Operation Donnerkeil
The German flotilla had reached home ports on the evening of the 12 February. However, while the threat from RAF bombers in daylight had now gone, Bomber Command was soon making night bombing attacks on Kiel’s port. "Gneisenau" was moved into an inner basin alongside her depot ship, "Monte Olivia". The hatches were left open and her tanks, still containing a large amount of fuel, were left unattended. RAF Bomber Command made its first attack on the night of the 25/26 February, when 61 bombers flew over Kiel. "Monte Olivia" was destroyed but "Gneisenau" escaped. On 26/27 February another 61 RAF bombers returned. A bomb penetrated "Gneisenau"s foredeck and exploded. The oil fumes from the tanks ignited and the ship was engulfed in fire from her bow to the Anton turret. The entire forward part of the bow needed to be replaced. She steamed to Gdynia, in Poland on 4 April where she was decommissioned out of range of RAF bombers. "Gneisenau" did not put to sea again. The raid cost three aircraft, one Hampton and two Wellingtons. German casualties amounted to 16 civilians and 116 sailors dead.
