Operation Carthage was a sad story although the mission was still successful, - the Gestapo HQ in Copenhagen was destroyed.
The sad part of the story was husshed by the British, but when RAF fighter pilots passing through Copenhagen on their way back from Germany in 1945 found out, they threw one hell of an airshow for the aid of the children that were injured from the raid.
A similar raid on Aalborg was a complete success, with the Target destroyed and a nearby hospital completely undamaged.
