Loos

British troops advancing through the gas cloud at Loos, 25 September 1915.

The division's first major offensive action was the Battle of Loos.The front lines were opposite Loos-en-Gohelle and on 27 August the divisional RE began work on a new start line. Each night an infantry battalion was brought up from Nœux-les-Mines to dig under the supervision of the sappers, and 2 miles (3.2 km) of trenches were dug in three weeks, including special recesses for gas cylinders. At 06.30 on 25 September, after a 40-minute discharge of poison gas, the infantry of 47th Division 'went over the top' accompanied by parties of sappers. Two sections from 1/3rd Fd Co were with 140th (4th London) Brigade and two from 1/4th Fd Co were with 141st (5th London) Brigade; two more sections of 1/3rd Fd Co were with 142nd (6th London) Brigade, which was only to make a demonstration. The remainder of the Divisional RE was in reserve. Casualties in the attack were moderate, and the division's two attacking brigades took their objectives with the exception of one strongpoint where the Germans held out for 48 hours. Major E.B. Blogg, OC of 1/4th Fd Co, was awarded a Distinguished Service Order (DSO) after he went out under heavy shellfire to cut the electric leads to mines laid by the enemy under the church tower at Loos. However, the flanking divisions had not done as well, and 47th Division was forced to fight to hold onto its gains. After four days the frontline brigades were relieved, while 142nd Bde relieved part of the Guards Division, and in turn spent three days in the line. During this period the brigade signal office in a Loos cellar was blown in, causing casualties, but communication back to Divisional HQ was restored in about 10 minutes/^[44][45][46]

Once the front line had settled down, signal lines were quickly laid from brigade HQs to battalion HQs and in some cases company HQs, while the motorcycle despatch riders (DRs) did good work on the exposed road into Loos. Maintaining communication from divisional HQ back to corps HQ proved more difficult, because wagon movements after dar continually disrupted the signal cables.^[47] The division was engaged on 8 October when heavy enemy counter-attacks were repulsed. IV Corps used 9000 Grenades in two-and-a-half hours, all of which had to be fused by the RE working under great pressure.^[45][48]

47th Division spent the winter of 1915–16 in the Loos salient, with the REs attempting to shore up trenches collapsing under incessant rain. The divisional RE built a new fire trench using Russian saps, but this was damaged by German mining. On 23 January British tunnellers blew 'Harrison Crater', but this did much damage to the British trenches. In attempting to seize and consolidate the crater, 1/4th Fd Co suffered heavy casualties and had to be relieved by 2/3rd Fd Co. The crater was lost later after a German retaliatory mine was fired. On 15 February the division was relieved and went into GHQ Reserve.^[49][50]

From March to July the division was in the Vimy area, where there was intensive mining by both sides and the sappers were employed in consolidating the craters. Major Blogg was mortally wounded by a sniper in March and his successor was killed within a few days. On 3 May the British fired four mines north of 'Ersatz Avenue' trench forming three big craters, which were seized and consolidated by the 1/21st Londons and 2/3rd London Fd Co. One of these craters was named 'Love Crater' after Major Love, OC 2/3rd Fd Co. The crater lips gave splendid observation over the German lines. On 21 May the Germans began an intensive bombardment of this area, extending into the British rear areas. The smoke and dust thrown up obscured observation for the British guns, and lachrymatory shells increased the confusion. After fours hours the Germans fired a mine and attacked in overwhelming numbers: they 'had little more to do that take possession of the 140th Brigade sector'. The situation was so critical for a while that all three companies of 47th Divisional RE were brought up under the CRE, Lieutenant-Colonel Sydney D'Aguilar Crookshank, to man the trenches. In June 1/19th Londons carried out a trench raid, accompanied by sappers from 1/4th London Fd Co carrying slabs of Gun-cotton to blow in dugouts.^[51][52][53]

High Wood

In August the division moved to the Somme sector to join the British offensive, and began training for an attack at High Wood. This was made on 15 September, resulting in extremely heavy casualties; the RE went in with the attackers and 2/3rd London Fd Co were instrumental in consolidating the 'Starfish Line' after its capture on 18 September.^[54][55] 47th (2nd London) Division took part in further attacks on the Somme in October, capturing Eaucourt l'Abbaye before being relieved and sent to the Ypres Salient, where it spent the winter in trench warfare and raiding.^[56][57]

On 1 February 1917 all TF RE companies received numbers; in 47th Divisional RE they were assigned as follows:^{[21][37][34][58]}

• 1/3rd London Fd Co became 517th (1/3rd London)
• 1/4th London Fd Co became 518th (1/4th London)
• 2/3rd London Fd Co became 520th (2/3rd London)

On 20 February a party from 520th Fd Co and 2nd Australian Tunnelling Company accompanied 1/6th Londons in a successful trench raid near Hill 60, but a similar raid next month by 1/18th Londons and a detachment of 517th Fd Co turned into a pitched battle with heavy casualties. The division took part in the Battle of Messines in June, when a deep penetration was made into the enemy position and the signal company quickly established communications. 47th (2nd L) Division then remained in the Ypres Salient, with the sappers working under shellfire to prepare tracks and railways for the resumption of the Third Ypres Offensive (the Battle of the Menin Road Ridge) in September.^[59][60]

Bourlon Wood

47th (2nd London) Division left the Ypres Salient on 21 September and travelled south to hold the line around Oppy and Gavrelle until November, where the infantry carried out a major trench raid on 4 November with RE demolition teams and signal parties in support. It then went to take over positions in Bourlon Wood that had been captured during the Battle of Cambrai. The relief was carried out under gas shelling, and on 30 November the division was hit by a fierce German counter-attack. Some of the RE acted as infantry reinforcing the hard-pressed 1/15th Londons, others as stretcher-bearers. After bitter fighting and heavy casualties, the division was ordered to retreat on the night of 4/5 December while the RE destroyed dugouts and equipment that could not be withdrawn, and the signallers recovered their cables. They were the last to leave the wood, blowing up the captured enemy guns that had not been taken away, and destroying the catacombs under Graincourt.^[61][62]

Spring Offensive

The German spring offensive broke on 47th Division's positions near Cambrai on 21 March 1918. Casualties were heavy, and the division was withdrawn that night, coordinated by the Signal Company's buried cable communications. It continued to be forced back the following day, and the field companies went into the line to reinforce the infantry, proving in the words of the divisional history 'that they were as good fighters as they were engineers'. On 24 March the Germans threatened the retreat of the divisional transport, but the divisional RE and pioneer battalion defended the road until it could withdraw, causing heavy casualties to the attackers. By now the division had no cable communications and had to rely on despatch riders: its OC, Major W.F. Bruce, took vital messages up to the brigade HQs in person, and was captured. The division crossed the Ancre on 25/26 March, and got one day's rest before going back to improve the defence line. On the night of 3/4 April a party of 518th Fd Co went out with an infantry fighting patrol to destroy Black Horse Bridge. On 5 April the Germans made a heavy attack on the division, but were held after desperate fighting. 47th Division was finally relieved on 8/9 April.^[63][64]

Hundred Days

47th (2nd London) Division occupied a quiet part of the line until August while it rested and absorbed drafts, though there was plenty of work for the sappers digging new trenches and constructing concrete machine gun positions and dugouts. The division joined in the Allied Hundred Days Offensive on 22 August, meeting strong opposition, but captured its objectives after a night attack on 23/24 August. The advance continued from 31 August to 2 September. The CRE had his sappers and pioneers hard on the heels of the advancing infantry, who ended this phase by constructing crossings over the Canal du Nord.^[65][66][67]

By now the division was very weak, and it was withdrawn to prepare to relieve another division from the Italian Front. However, the Germans on the Western Front were retreating quickly, and 47th (2nd L) Division was brought back to the line to hasten their departure. The RE spent much time repairing roads and bridges to allow the transport to keep up with the advance. The division masked Lille for 10 days and then took the outer forts with little opposition on 16 October. It took part in the official entry into the city on 28 October. On 8 November the enemy evacuated Tournai, the sappers built footbridges over the Scheldt and began work on a heavy trestle bridge. The 1st Engineer Company of the Portuguese Army was attached to the division at this time. The Armistice with Germany took effect on 11 November, and the division concentrated round Tournai.^[21][68][69]

While awaiting demobilisation, the division repaired the Tournai–Ath railway, and then settled down into winter quarters around Béthune, where it had originally concentrated in 1915. The first parties left for England in early January, and by 28 March all the units had been reduced to cadre strength.^[21][70][71]

Salonika

60th (2/2nd London) Division had been earmarked to join in the Somme Offensive, but instead was switched to the Macedonian front. This required the RE companies to reorganise with pack mule transport rather than horse-drawn wagons. The CRE and 2/4th Fd Co left in the first ship from Marseille, SS Translyvania, and reached Salonika with 179th Bde on 30 November. The rest of the division followed by mid-December, while 179th Bde and 2/4th Fd Co were sent to guard the southwestern approaches to Salonika: the sappers had to repair the railway to allow their train to proceed. The company then spent the next three months constructing a pier at Skala Vromeria, defences to cover the Petra Pass, and the requisite roads including 'Chelsea Bridge' (built by 2/4th Fd Co and a working party of the 2nd London Scottish). At the end of 1916 the rest of the divisional RE moved up to the main line, 1/6th Fd Co joining 180th Bde south of Lake Doiran, 3/3rd Fd Co and 181 Bde arriving last, east of the Lake.^{[72][80][81][82]}

The field companies in 60th Divisional RE were now assigned numbers as follows:^[72][34][83]

• 3/3rd London Fd Co became 519th (3/3rd London) on 5 February
• 2/4th London Fd Co became 521st (2/4th London) on 7 February
• 1/6th London Fd Co became 522nd (1/6th London) on 1 February

On the Doiran front 60th Division began a policy of vigorous raiding of Bulgarian outposts. For example, on the evening of 17 February 181st Bde attacked the village of Brest, evicting the garrison and holding it all night while an RE demolition party rendered it untenable. Each time the Bulgarians repaired the defences, the brigade raided Brest and the Hodza Redoubt, taking prisoners and causing destruction. At the end of March 179 Bde and 521st Fd Co rejoined the division, which took up new positions for the opening of the Spring offensive.^[84][83]

On 5 April German Gotha bombers raided Karasuli, catching a column of waggons waiting to load up with RE stores: only one man was wounded but all the waggons and mules were destroyed. The Allies launched their offensive (the Battle of Doiran at the end of April, with 60th Division carrying out a diversionary raid on the night of 24/25 April against 'The Nose'. The infantry of 2/20th Londons were accompanied by sappers of 519th Fd Co carrying Bangalore torpedoes to breach the barbed wire. They were caught by searchlights while negotiating the gaps in the wire, and only one party was able to dash through into the Bulgarian trenches. Here they fought off counter-attacks while the sappers carried out demolitions before withdrawing; casualties were severe. For the second phase of the battle on 8/9 May 179th Bde carried out a surprise attack accompanied by 521st Fd Co. All five objectives were taken without serious resistance, and the gains were extended the following morning and then counter-attacks were beaten back on 10 May while the sappers and pioneers consolidated the ground won.^[85][86][87]

Palestine

The fighting died down in later May, and on 1 June 60th Division was given new orders: it was to re-embark on 12 June, bound for Egypt to reinforce the Egyptian Expeditionary Force (EEF). After arriving in Alexandria on 3 July the engineers had to reorganise for wheeled and camel transport, followed by desert training. Lieutenant-Colonel C.B. Thomson took over as CRE on 27 August. On 30 October the 60th Division concentrated for the Third Battle of Gaza and took part in the attack on Beersheba the following day. The division advanced with two brigades (179th and 181st), each accompanied by its field company, the third field company being held ready to move into Beersheba at short notice. The town fell to the Desert Mounted Corps, and 519th and 521st Fd Cos entered the town to get the water supply going: only two of 17 wells had been destroyed, though the remainder were prepared for demolition. The Sheria position, with its water supply, was taken on 6–7 November after a 15 miles (24 km) march across the desert and a pre-dawn attack, and Huj was taken on 8 November.^{[72][88][89][90]}

After a rest, the division marched again in the operation to capture Jerusalem, advancing on 8 December with 179th Bde and a section of 521st Fd Co leading the attack on the right, 180th Bde with 519th Fd Co on the left, and 181st Bde and 522nd Fd Co in reserve. As 179th Bde's columns advanced, RE parties with pioneers were dropped off at intervals to improve the muddy track and direct the follow-up troops. Despite bad weather, the attacks were successful in driving back the Turks, and on 9 December the city's civilian leaders surrendered it to two sergeants of 2/19th Londons. The division then had to defend its gains against fierce Turkish counter-attacks (22–28 December) before resuming its advance to positions from which it could cover the city during the next pause in operations.^{[72][91][92][93]}

Early in February the division began advancing on Jericho, advancing as three independent brigade groups with their usual RE companies attached (the RE detachment with 180th Bde in the centre was specially tasked with repairing culverts). After preliminary moves on 14 February, the brigades attacked on 18 February and by 21 February had fought their way over very bad ground to within 7 miles (11 km) of Jericho, and the town was captured next day by the ANZAC Mounted Division.^{[72][94][95][96]}

Units returning from the second Transjordan raid crossing the pontoon bridge at El Auja.

60th Division was now tasked with crossing the River Jordan in order to raid the enemy's communications around Amman: it was to cross at Ghoraniyeh, one of two bridging sites that had been identified. 521st Field Co extemporised rafts of timber, wire netting and tarpaulin to get infantry across and then form the basis for an infantry assault bridge. However, the floodwater prevented them being launched on the nights of 21/22 or 22/23 March. The first infantry only got across on 23 March after the Anzacs had already crossed, 521st's assault bridge then being quickly followed by a barrel pier constructed by 519th Fd Co and by a pontoon bridge by the army's bridging train. 522nd Field Co then began to build a heavy timber trestle bridge on 25 March, but the rising floodwater caused this to be abandoned on 29 March. Instead 522 Fd Co built a suspension bridge between 1 and 18 April after cables had been brought from Egypt. A second raid lasting from 30 April to 4 May was launched from this bridgehead.^{[72][97][98][99]}

The EEF now had to provide urgent reinforcements to counter the German Spring Offensive on the Western Front. 60th Division was 'Indianised' and about three-quarters of its London infantry battalions went to France, to be replaced with Indian Army units. In the Divisional RE, 522nd Fd Co went to 7th (Meerut) Division on 18 July 1918, and No 1 Company, King George V's Own Bengal Sappers and Miners joined in exchange.^{[72][34][100][101][102]}

Megiddo

The final offensive in Palestine (the Battle of Megiddo) began on 19 September, with 60th and 7th (Meerut) Divisions rapidly breaking through along the coastal plain to capture Tulkarm and Tabsor respectively, opening a gap for the cavalry to exploit.^{[72][102][103][104][105]}

The pursuit after the battle was a cavalry affair, and 60th Division was left behind on battlefield salvage work, while 7th (Meerut) Division participated in the advance across the Jordan to Baalbek. The Armistice with Turkey came into force on 31 October. By 26 November the whole of 60th Division was back in Alexandria, where the RE carried out various engineering tasks while demobilisation got under way. At one point 519th Fd Co was put under orders to proceed to Russia, but these were cancelled. Units were progressively reduced to cadre, and the division was disbanded on 31 May 1919.^[72][106] 7th (Meerut) Division remained as part of the occupation force in Palestine until its units were dispersed in 1920.^[102]

Middle East

During August 1942 the division moved to the embarkation ports of Liverpool and Glasgow, and sailed for the Middle East on 25 August. The fast troop convoy reached South Africa safely, but the slow convoy carrying guns and vehicles was heavily attacked by U-boats off the coast of West Africa and lost several ships. From South Africa most of the troops sailed to Bombay, while the RE drivers were sent to Egypt to collect the vehicles that had escaped the U-boats, which arrived at Suez in December. The main. body sailed from Bombay to Basra in Iraq on 4 November and then by road and rail to Kirkuk where they were joined by the drivers who had brought the transport overland from Suez.^[119][146]

56th Divisional RE spent the spring of 1943 training for mountain warfare, particularly bridging ravines. In March, 168th (2nd London) Brigade accompanied by 501 Fd Co was detached to Palestine. Then the rest of the division began an overland drive to join Eighth Army in Tunisia, driving some 3,200 miles (5,100 km) between 18 March and 19 April. An advanced party of RE officers and NCOs had gone forward earlier (covering 1,330 miles (2,140 km) in four days) to be attached to 51st (Highland) Infantry Division for battle experience.^{[117][123][119][147]}

Tunisia

On 22 April 201 Guards Motor Brigade joined the division as temporary replacement for 168 Bde, bringing with it 42 Fd Co, which became part of divisional RE for the rest of the year. Next day 56th (London) Division went into action for the first time at Enfidaville. The infantry were roughly handled, and the divisional RE suffered its first casualties, from shellfire and mines. The final attack on Tunis (Operation Strike) began on 6 May, the division meeting strong resistance before the Germans surrendered on 12 May. 56th Divisional RE built its first operational bridge (a Small Box Girder (SBG) bridge) just before the end of the fighting. By the end of the month division had been pulled back to Tripoli to train for the invasion of Italy. Divisional RE lost 10 men to an accident with Bangalore torpedoes, while Sapper Robert Southall of 221 Fd Co won a George Medal for gallantry while clearing mines.^{[117][119][148][149][150][151][152]}

Sicily

RE sappers repairing Primosole Bridge after its final capture, July 1943.

While the rest of 56th (London) Division trained for the assault on mainland Italy, 168 Bde and 501 Fd Co took a leading part in the Allied invasion of Sicily (Operation Husky) with 50th (Northumbrian) Infantry Division. The company had trained at the Combined Operations Training Centre at the Great Bitter Lake in Egypt, then sailed in convoy from Alexandria. 168 Brigade Group landed on 13 July (D+3), after the rest of the division had taken its objectives; 501 Fd Co disembarked dryshod on the quay at Syracuse. The company was involved in 168 Bde's failed night attack beyond Primosole Bridge on 17/18 July, and later built a Folding Boat Equipment (FBE) bridge across the River Dittano there. It was then set to clearing mines and suffered several casualties. The retreating Germans had destroyed the cliff road at Taormina, and while XXX Corps Troops, Royal Engineers bridged the gap and a tunnelling company of the Royal Canadian Engineers excavated the cliff, 2 and 3 Platoons of 501 Fd Co were tasked with mine clearance on the beach below. While reconnoitring forward they became involved in a firefight with a German patrol. The other two platoons were landed north of Taormina to begin clearance from the other side. 50th (N) Division reached Messina on 17 August, when 168 Bde Group left the division. 501 Field Co constructed an SBG bridge and prepared launching points for the assault crossing of the Straits of Messina (Operation Baytown) on 3 September. After the beachhead had been secured and Eighth Army began driving north, 168 Bde and 510 Fd Co crossed over to travel overland to rejoin 56th (L) Division, which had landed at Salerno on 9 September.^{[153][154][155][156][157]}

Operation Avalanche

D7 Armoured bulldozer.

56th (London) Division landed as the right hand half of X Corps at Salerno before dawn on 9 September 1943 in Operation Avalanche. There were few beach defences, but once ashore there was plenty of work for the sappers. 503 (London) Fd Co (see below) was also present with one of the beach groups landed immediately after the first infantry waves. Bulldozer drivers from 220 Fd Co towed out seven bogged-down Sherman tanks of the Royal Scots Greys on the first morning. 221 Field Co sent a party to Montecorvino Airfield to disarm suspected demolition charges, but got involved in a firefight: the airfield was not fully cleared for several days. 563 Field Park Co came ashore during the morning and had a stores dump organised by evening. Sapper F. Martin of 563 Fd Park Co won a Military Medal (MM) for his work with a D7 armoured bulldozer, during which he was badly wounded. There was bitter fighting for 10 days along the Salerno beachhead: on 12 September 220 Fd Co took up defensive positions with its brigade when a German counter-attack threatened to break through, and on 14 September both 220 and 221 Fd Cos acted as infantry and took heavy casualties.^{[158][159][160]}

On 22 September the Allies broke out and X Corps headed north towards Naples. Meanwhile, the divisional reconnaissance unit (44th Reconnaissance Regiment) sent a mixed pursuit force, including a platoon of 220 Fd Co, eastward along Highway 18 to make contact with Eighth Army advancing from the south. It was held up by demolitions at Battipaglia, so 220 Fd Co built the first Bailey bridge on this front. There was another blown bridge 5 miles (8.0 km) further on, so 220 Fd Co constructed a bypass while 221 Fd Co began work on a second Bailey bridge. On X Corps' main axis of advance over the Sorrento Peninsula another platoon of 220 worked 'feverishly' to repair a damaged mountain road, and road clearance and repair became a major job as the force advanced across the plain of Naples. The retreating Germans had blown every bridge across the River Sarno for 8 miles (13 km) inland, but 56th Division captured an intact bridge at San Mauro and continued past Naples to Capua, where the Germans were making a stand on the River Volturno.^[161][162]

Volturno and Garigliano

The attempt to cross the Volturno began with a feint attack at Capua by 201 Guards Bde using assault boats, which was repulsed, but the neighbouring divisions got across, and 56th (L) crossed by a US-built bridge. The RE then set to work to build additional bridges, the main one being a Class 30 (30 ton load) Bailey pontoon, the first of its kind to be built operationally under fire, and something 56th Divisional Engineers had never tackled before. It became a joint effort of 220 Fd Co, 270 Fd Co from 46th Division and a corps RE company. 168 Bde Group, including 501 Fd Co, rejoined 56th (L) Division at Caserta during these operations. After the Volturno, X Corps made rapid progress up Highway 6 until it reached the Bernhardt Line in the mountains round Monte Camino. The sappers built jeep tracks through the mountains, but there was bitter fighting on Monte Camino itself that lasted until its capture on 9 December, when the division was rested.^{[163][164][165]}

The next obstacle in front of X Corps was the lower Garigliano river south of Monte Cassino. 56th (London) Division's attack on the night of 17 January launched the Battle of Monte Cassino. Many assault boats were sunk in the crossing, but the divisional RE built and operated rafts of varying types: 501 Fd Co providing a Class 40 Bailey pontoon ferry powered by eight outboard motors, which operated for a week without being hit by the enemy's accurate mortar fire. Two nights later construction began on a Class 40 Bailey pontoon bridge, which was completed by the evening of 20 January. However, fierce counter-attacks prevented X Corps from advancing far beyond the river.^{[166][167][168]}

Anzio

On 30 January 168 Bde (with 501 Fd Co) was about to resume the offensive on the Garigliano when it was hurriedly withdrawn to reinforce the landing further up the coast at Anzio, which had run into trouble. On 6 February the rest of 56th Division (less 201 Gds Bde and 42 Fd Co, which now left the division) was also withdrawn from the Gariglianao and landed as reinforcements at Anzio. Much of the work for the sappers consisted of repairing roads in the bridgehead, including quarrying the necessary stone, all under heavy artillery and air bombardment. There was also a programme of laying defensive wire and minefields. The infantry were continually engaged, and by 25 February were down to less than half strength, so the engineers had to go into the fighting line while enemy counter-attacks were repulsed. On 9 March the exhausted division and 501 Fd Co were evacuated from Anzio, but 220 and 221 Fd Cos remained behind working on roads and quarrying until 18 March.^{[117][119][151][169][170][171]}

56th Division now went back to Egypt for rest. While driving south to Taranto to embark, the divisional engineers spent a day bulldozing the road clear of volcanic ash from the eruption of Mount Vesuvius. On arrival at Port Said the division went into camp, leave was granted, and RE training resumed at various locations in Palestine and Syria. On 10 July the refitted division left Port Said to return to Taranto, from where it was sent to join V Corps with Eighth Army on the Adriatic coast of Italy.^[119][172]

Gothic Line

Massive engineering works were required in preparation for Eighth Army's assault on the Gothic Line (Operation Olive), including opening up two heavily demolished roads and erecting 40 separate Bailey bridges, of which 220 and 510 Fd Cos built one apiece near Pergola. V Corps opened the attack on 25 August, and by 1 September the Gothic Line had been cracked open, but 56th (L) Division coming up from reserve still had hard fighting at Monte Capello, Montefiore Conca village and the Gemmano ridge. During the Battle of Gemmano one RE bulldozer was forced by a German counter-attack to retreat down the ridge at speed, towing out a bogged jeep ambulance as it went. Eventually, 56th (L) Division bypassed the Gemmano ridge and crossed the Conca river, and finally took Gemmano village on 9 September. After a short rest, the division advanced on 16 September and fought its way to the swollen Fiumicino river by the beginning of October. At Savignano 501 Fd Co built a major bridge nicknamed 'Itsonitsoff' because the operation was 'on' and 'off' so many times during the week of fighting to secure the bridging site. By 7 October 56th (L) Division was exhausted and withdrawn, together with 563 Fd Park Co, while the field companies and 563's bridging platoon remained working in the line a few days longer.^[173][174]

Argenta Gap

In the middle of December the division returned to the line, moving via Forlì to Faenza, where it spent the winter months, divisional RE working on road maintenance, mine clearance, and repairing the floodbanks of the River Lamone.^[175][176] For 56th (L) Division the Spring 1945 offensive in Italy began on 5 April with an operation to clear a triangle of ground between the River Reno and the south-west corner of Comacchio Lagoon. 220 Field Co built a Class 40 and a Class 12 raft at dusk, ready to be towed into position, when No 1 Platoon would cross with the infantry. Then 221 and 501 Fd Cos were to build a Bailey pontoon bridge at dawn the following day. The infantry assault went in at 23.00 and early on 6 April a tug pulled the Class 40 raft up, to be loaded with a bulldozer. Unfortunately there were still Germans dug in on the far bank, who sank the raft with an anti-tank (A/T) rocket, the dozer driver being drowned. In the subsequent firefight and recovery attempts led by the CRE, Lieutenant-Colonel R.E.C. Hughes, the OCs of 220, 501 and 563 Cos, and the Regimental Sergeant Major all became casualties. After a tank shelled the Germans, the post surrendered to Lieutenant-Colonel Hughes. The sappers then cleared dozens of mines from the approaches to allow the 282 feet (86 m) pontoon bridge to be built.^{[177][178][179]}

On the night of 10/11 April 56th Division launched Operation Impact Plain to widen the bridgehead and open the 'Argenta Gap', for which the divisional RE had been reinforced by a company of the African Pioneer Corps and by Royal Army Service Corps troops transporting bridging equipment and dozers, and driving tipper lorries. Prior to the assault 56th Divisional RE built two Bailey bridges to allow amphibious LVTs known as 'Fantails' to reach their assembly area, then following behind the advance built several bridges across the network of irrigation and drainage canals. On 15 April 501 Fd Co put up a 160 feet (49 m) FBE bridge and 221 Fd Co a 70 feet (21 m) Bailey. 56th Division renewed the attack that day, and on 16 April it took Bastia in Operation Impact Royal. However, it was held up at the Marina Canal. During 17 April 501 Fd Co was employed making a diversion route across country to the canal. Next day the divisional RE began to dam the canal, but handed the work over to 8th Army Troops RE in order to keep up with its division as the advance accelerated.^{[180][181][182]}

On 25 April the division reached the River Po. This was a formidable obstacle, but 56th (L) Division planned to make an assault crossing that night using LVTs and storm boats, while 220 and 221 Fd Cos built and operated three Class 9 close support rafts and two Class 40 rafts; there was also a Class 50/60 raft built and operated by H Assault Squadron of 2nd Armoured Regiment, RE. 501 Field Co supported 169 Bde in the assault and built ramps for the LVTs. In the event the infantry got across by storm boat in the afternoon to occupy Crespino, and the river assault after nightfall was almost unopposed. The Class 50/60 raft had arrived without motors, so the engines from close support rafts had to be used for it, reducing the number available.^{[183][184][185]}

The division pushed on to the Adige, where 501 Fd Co found a suitable bridging site near Rovigo and began a 392 feet (119 m) pontoon Bailey, which it then handed over to 221 Fd Co and 564 Fd Co of V Corps Troops RE for completion. 56th (London) Division and 2nd New Zealand Division were given the task of capturing Venice, which they did on 28 April after a brief action. The war in Italy ended on 2 May with the Surrender of Caserta.^{[186][187][188]}

56th (London) Divisional RE remained in the area of Trieste and Pula, building camps, frontier posts and hospitals, until they were disbanded in the summer of 1946.^[189]

Le Havre

42nd Assault Rgt went into action in Operation Astonia to capture Le Havre on the evening of 10 September. Each attacking infantry brigade was supported by an assault team from 79th Armoured Division: a mixed group of Churchill AVREs, Sherman Crab mine flails and Churchill Crocodile flamethrowing tanks. Part of 222 Assault Sqn provided AVREs for 56 Bde while 2 Troop was with 146 Bde, both of 49th (West Riding) Division. Three of the chosen lanes of attack crossed the fortress's A/T ditch. For these the regiment employed bridgelayer tanks and the AVRE 'Conger' mine clearance device (a flexible hose filled with liquid explosive) for its first use in action. An AVRE of 222 Assault Sqn deployed an older AVRE 'Snake' (utilising a rigid pipe instead of a flexible pipe), but this exploded as it was pushed across the ditch. The AVRE was then put out of action reversing over a mine, and the following bridgelaying AVRE also struck a mine. Thus the 'Hazel' lane through the defences had to be abandoned. In another lane the SBG bridge on the AVRE was hit and fell. A reserve bridge was brought up but was hit 500 yards (460 m) from the ditch. The AVRE crew dismounted and under heavy fire succeeded after 20 minutes in winching it into position. Several AVREs were knocked out by 88 mm A/T guns, but the remainder silenced enemy guns and used their Petard mortars against concrete positions. Once the town was entered, 2 Trp of 222 Sqn pushed on with 146 Bde to take Harfleur, destroying A/T guns and roadblocks as they went. At one point the AVREs used their petards to fell trees and fill in a ditch. The capture of Le Havre was completed on 12 September.^{[208][209][210]}

Low Countries

79th Armoured Division's squadrons with their varied equipment (the 'Funnies') were often widely scattered and rarely under regimental control. On 4 November 51st (Highland) Division attacked towards 's-Hertogenbosch with support from 79th Division, including a troop of 222 Assault Sqn, which transported an SBG bridge across 4 miles (6.4 km) of difficult terrain and laid it successfully over a 28 feet (8.5 m) ditch to allow armour to cross.^[211][212]

Offensive operations came to a virtual halt during the winter, and 222 Aslt Sqn rested at Waterscheide. Early in 1945 the squadron took part in Operation Blackcock to clear the Roer Triangle. On 17 January a troop laid three bridges for 7th Armoured Division's attack on Susteren, while the other two troops operated with two columns formed by 8th Armoured Bde and 52nd (Lowland) Division. Captain Herbert Baynton-Jones of 222 Sqn supporting 4th/7th Dragoon Guards was awarded a Military Cross (MC) for dismounting to take control of an RE mineclearing detachment and then leading his troop of AVREs to attack a village with their petards.^{[212][213][214]}

Germany

AVREs with SBG bridge and fascines move up during Operation Veritable.

42nd Assault Rgt next participated in the Battle of the Reichswald (Operation Veritable). On 8 February 222 Assault Sqn supported 51st (Highland) Division, which advanced down three lanes cleared by flails. In each lane the flails were followed by two AVRE bridgelayers and two carrying Fascines. In the right hand lane all went well; the centre lane was blocked by a knocked-out flail tank, but the AVREs completed a fascine crossing by the evening; the third lane was impassable due to mud. Captain D. Hamilton, OC 1 Trp, was awarded an MC for this operation. On 13/14 February 51st HD crossed the River Niers and took Heijin, where 222 Aslt Sqn bridged a crater and destroyed a roadblock, then laid a bridge that allowed the division to enter Hommersum. 222 Assault Sqn next helped 51st HD to capture Hervorst on 17 February; during the fighting 3 Trp attacked and destroyed a large pillbox with petards. Then on 19–20 March the squadron helped 51st HD capture Goch, penetrating the defences and reducing pillboxes.^{[215][216][217][218]}

While Veritable continued, 42 Assault Rgt was withdrawn to Nijmegen to train for the Rhine crossing (Operation Plunder), particularly operating Class 50/60 rafts. These consisted of five linked pontoons supporting a section of roadway to ferry a tank. For the final stretch of their journey to the riverbank, the heavy pontoons on sledges were towed by AVREs. Once launched, the ferries were hauled to and fro across the river by RAF Barrage balloon winches.^{[216][219][220]} For the crossing on the night of 23/24 March, 42nd Assault Rgt was assigned to 15th (Scottish) Division leading XII Corps' attack at Xanten. Having hauled their pontoons through the mud, 42nd Assault Rgt began assembling its rafts at 02.45 on 24 March, and had three operational by 21.00 that night. Two ferry points were used, each with two rafts; 222 Assault Sqn and half of 81 Assault Sqn operated the ferry point codenamed 'Abdullah'. The regiment ran its ferries until the afternoon of 26 March when a Bailey bridge was completed (by 503 Fd Co, see below), during which period it carried 311 tanks and self-propelled guns and a few wheeled vehicles.^{[216][221][222]}

After the Rhine crossing, 21st Army Group fanned out over North Germany towards the River Elbe. 222 Assault Sqn was in Second Army Reserve, then supported 3rd Division in crossing the flooded approaches to Bremen, using their petards to flush defenders out of strongpoints, and skid Baileys to cross breaches in the causeways. Most of Bremen was in British hands by 27 April. 21st Army Group continued its advance until the German surrender at Lüneburg Heath on 4 May, when the squadron had reached Baden, Lower Saxony.^{[223][224][225]}

It was intended to reorganise 42 Assault Rgt for service in the Far East, but this was cancelled after the Surrender of Japan, and 222 Aslt Sqn was disbanded at Garlstorf in Germany.^[223]

Italy

The company next went to Gaza to join 35 Beach Group, in training as a reserve unit for Operation Husky. It was then assigned to Operation Avalanche, the landing at Salerno (see above). It was transported by road and sea to Algeria, concentrating at Bougie. Company Sergeant Major L.J. King was awarded a George Medal for rescuing some gunners from a vehicle whose ammunition was burning after a bombing raid. 35 Beach Group landed at Salerno on 9 September immediately after the leading infantry. The sappers' task was to lay Sommerfeld tracking and create roads across the beach to the intended supply dumps, as well as clear minefields. They suffered numerous casualties from shellfire, and won an MBE, two MCs and two MMs during the beachhead fighting. After the armies moved north, 503 Fd Co remained at Salerno for the rest of the year, carrying out municipal and civil engineering, repairing the sewer system and the airfield, and operating a stone quarry for the usual road repairs. Formally, 503 Fd Co was now part of 14th GHQ Troops RE.Early in January 1944 the company moved north to the Volturno, then to Teano near Naples. In early March the company was withdrawn and sailed from Naples to the UK^{[227][228][123]}

Normandy

The company landed at Liverpool, and after leave and training joined 7th Army Troops RE. This group of sapper units was earmarked for Operation Overlord (see above). It landed in Normandy on D+6, and one of its first tasks was to construct a 4 miles (6.4 km) road to bypass the congested town centre of Bayeux. This was 45 feet (14 m) wide between side drains, with a roadway 21 feet (6.4 m) wide chiefly composed of Sommerfeld track and chestnut paling covered with sand and gravel. The company then moved to Caen on bridge and road maintenance, losing casualties to enemy snipers. After 21st Army Group's breakout from the Normandy beachhead 7th Army TRE went to bridge the Seine, but 503 Fd Co was not involved. Instead it went to camouflage the oil tanks erected for the Pluto oil pipeline at Boulogne and clear mines in the area. They also cleared beach obstacles at Ambleteuse and at Ostend once that port had been captured, losing further casualties in this dangerous work.^{[229][230][231]}

Holland and Germany

503 Field Co spent the winter of 1944–45 in South Holland on bridge and road maintenance. At Gennep in February it participated with 7th ATRE in building the longest Class 40 Bailey bridge yet constructed, (4,008 feet (1,222 m) including the approach viaducts across the floods at each end), followed in March by a 550 feet (170 m) Class 40 floating Bailey at Well, Limburg, and a Class 70 high level pontoon bridge at Venlo. For the Rhine crossing (Operation Plunder, see above) 503 Fd Co and 7th ATRE built a Class 40 tactical pontoon Bailey at Xanten, utilising an existing ferry site. Craters in the ferry approach road had to be filled by tipper trucks before zero hour while the barrage was being fired, but the bridge was built in 31 hours, the first one completed during the operation. It carried 29,139 vehicles in the next six days as 21st Army Group advanced across Germany.^[232][233]

503 Field Co was then ordered to Münster, but while the rest of 7th ATRE advanced to bridge the Elbe, the company was diverted back into Holland to join HQ Netherland Force, just before VE Day. Over the following months the company was engaged in rehabilitation work in the liberated area, principally bridging rivers and canals, installing Bailey bridges with lifting sections. It also trained 5 Engineer Company of the Royal Netherlands Army in Bailey bridging, and supervised German Prisoners of War clearing mines on the Frisian Islands. 503 Field Co remained in Holland until November 1945 and was eventually disbanded in Minden, Germany.^[234][235]
