Battle of the Atlantic

Between July 1943 and 22 April 1944, Buckley operated along the eastern seaboard as training ship for prospective officers and nucleus crews of other destroyer escorts.

On 22 April 1944, she joined hunter-killer Task Group 21.11 (TG 21.11) for a sweep of the North Atlantic and Mediterranean convoy routes. The ship was west of Africa near the Cape Verde Islands in May.^[1] In the early morning of 6 May, aircraft from the escort carrier Block Island (CVE-21) reported an enemy submarine approximately 20 miles from Buckley. The ship steamed toward the U-boat at full speed. Meanwhile, U-66 had exhausted supplies and surfaced to recharge batteries and waited for a supply ship. At 3:08 AM, believing the approaching ship was German, U-66 launched three flares. The distance between the two vessels was 4,000 yards when the U-boat realized the actual identity of the ship approaching them.^[1]

U-66 fired a torpedo, which Buckley dodged. The sub fired machine guns at the destroyer escort which returned fire with three-inch guns hitting the submarine's forecastle. Buckley then unleashed all its weapons on their target, repeatedly striking the conning tower as the sub backed away and fired another torpedo, which the Buckley avoided.^[1] At 0328 Buckley rammed the German submarine U-66 and the two vessels were briefly locked together. Some members of the German crew exited their burning boat, and hand-to-hand combat ensued using small arms and whatever weapons were at hand (such as coffee mugs and shell casings). The Buckley backed off, but the submarine pursued, striking the Buckley on the starboard side at the engine room. The collision also broke the ship's starboard propeller shaft.^[1] The U-66 disengaged and slowly backed away, but not before hand grenades were thrown into the gaping hole in the flaming conning tower.^[1] The submarine sank at 0341 in 17°17′N 32°24′W / 17.283°N 32.400°W / 17.283; -32.400 (German submarine U-66).

Buckley picked up 36 German survivors, transferred them to the Block Island and then retired to New York where she underwent repairs until 14 June 1944. For this most interesting action, regarded by several high naval officers as being the most "exciting" anti-submarine kill in the Battle of the Atlantic, Buckley personnel were authorized to wear a combat star in the European-African Theater ribbon. The then commanding officer, Lt. Comdr. Brent M. Abel, USNR, of Cambridge, Massachusetts, was awarded the Navy Cross for his part in its execution.

After completing refresher training at Casco Bay, Maine, in July 1944, Buckley escorted two convoys to North Africa (14 July – 7 November 1944). She then operated on anti-submarine and convoy escort duty along the eastern seaboard and in the North Atlantic until June 1945. During this period Buckley and Reuben James (DE-153) sank the German submarine U-548 on 19 April 1945 in 42°19′N 61°45′W / 42.317°N 61.750°W / 42.317; -61.750 (German submarine U-548). Buckley escorted one more convoy to Algeria during June–July 1945, before returning to the United States.

Conversion and fate

Buckley after her conversion, in late 1945.

Upon her return to the east coast, she commenced conversion to a radar picket ship. In October 1945, she participated in the Navy Day ceremonies at Jacksonville, Florida, and then on 31 October reported to the 16th Fleet at St. Johns River, Florida. Buckley was placed out of commission in reserve on 3 July 1946. On 26 April 1949 her classification was changed to DER-51 (radar picket destroyer escort), and on 29 September 1954, she was reclassified back to DE-51.

Buckley was stricken from the Naval Vessel Register on 1 June 1968; she was sold for scrapping July 1969.
