Operation Carthage, on 21 March 1945, was a controversial British air raid on Copenhagen, Denmark,
The attacking force consisted of Royal Air Force de Havilland Mosquito F.B.VI fast bombers of No. 21 Squadron RAF, No. 464 Squadron RAAF, and No. 487 Squadron RNZAF, from the No. 140 Wing RAF. These were organised in three waves of six aircraft, with two reconnaissance Mosquito B.IVs from the Royal Air Force Film Production Unit to record the results of the attack. Thirty RAF P-51 Mustang fighters gave air cover from German aircraft, and these also attacked antiaircraft guns during the raid.
The force left RAF Fersfield in the morning and it reached Copenhagen after 11:00. The raid was carried out at rooftop level. In the course of the initial attack, a Mosquito hit a lamp post, damaging its wing, and the plane crashed into the Jeanne d'Arc School, about 1.5 km (0.93 mi) from the target. Several bombers in the second and third wave mistakenly attacked the burning school, thinking it was their target. Sadly 86 schoolchildren and 18 adults died, many of which were nuns.
