Even before the breakout into the North Atlantic, Lütjens had decided against conducting an underway refuelling in the Greenland Sea with Weissenburg,[7] one of the pre-positioned German tankers, before his ships entered the Denmark Strait. And when, as a result of the battle with Hood and Prince of Wales, Bismarck lost access to several thousand tons of fuel in her forecastle due to a shell hit from Prince of Wales (aft of the forecastle, in her anchor locker), Lütjens had to order his ships to slow down to conserve fuel. The decrease in speed made Force H’s airborne torpedo attacks inevitable, and those attacks led directly to the final encounter with the Home Fleet.
