Amazingly, a photograph of the attack is in the IWM archives.
The Liberator (serial 120/H) was piloted by Flight Lieutenant Alexander Fraser, Royal Australian Air Force, operating from Reykjavik, Iceland. As you can see from the photograph, Fraser caught U-200 on the surface and his two depth charges straddled the U-boat perfectly.
Fraser was awarded a bar to his Distinguished Flying Cross for his “magnificent example of determination to destroy the enemy in the face of opposition.”
U-200 was lost with all hands. The figure of 67 dead includes not only the U-boat’s crew, but also a 7-man German special forces unit of Brandenburg commandos. The Brandenburg unit was in transit to South Africa, where they were to be landed and make contact with anti-British sympathizers in the Boer community.
