Accident in Rotterdam and death

Coulisa took part in the Rotterdam CSIO5* in June 2014, struggling to complete the second round of the Nations Cup on June 20 with 16 faults.^[14][15] Denis Lynch nevertheless entered her in the Rotterdam Port Grand Prix on Sunday June 22, 2014. The pair commit a big fault on the river, which Coulisa barely manages to cross under the severe blows of her rider's whip and spurs, after nearly stumbling.^[14][16][17] Frightened by the blows, she missed a stride on the penultimate obstacle (no. 11), three Spa bars, and fell heavily.^{[14][17][18][19]} The fall, broadcast live on Dutch television, provoked a widespread "reaction of horror", including among the riders, journalists and judges.^[17][20] Lynch escaped unhurt.^[21]

Spa bars, the type of obstacle in which Coulisa fell.

Transported to a local veterinary clinic, Coulisa presented a visible wound to a hind limb.^[14][21][22] The following day, June 23, veterinary examination revealed a hip fracture.^[23] According to the Swiss media outlet Le Cavalier romand, the case caused quite a stir.^[19] With the ensuing surgery^[24] announced as successful in early July 2014, a recovery period lasting between four and eight months is announced for Coulisa, before her potential return to competition.^[25][26][27]

After three months of attempted care, Coulisa is euthanized on October 11, 2014, at the age of 10.^{[28][29][30][31]}

Dirk Willem Rosie, editor-in-chief of the Dutch magazine Paardenkrant,^[17] as well as French journalist Sébastien Roullier (Grand Prix magazine)^[3] and Dutch journalist René Banierink (BN DeStem)^[20] were astonished that Lynch, known for past doping on his horses, had not been punished for his dangerous attitude towards his mare. Despite a request for intervention from the president of the Geesteren CSI jury, Joop van Dijk de Wierden, Lynch received no sanction.^[20]
