Route choice turned bad intelligence into a predictable breakout

A false report placed four British battleships and a carrier at Scapa Flow and encouraged Lütjens to leave Norway quickly. Lindemann preferred the route south of Iceland and later wanted the operation cancelled as reports of British capital ships accumulated. Lütjens chose Denmark Strait, where ice and poor visibility narrowed the patrol area but could shield the ships from air attack. He declined to increase speed to stay beneath a moving cloud bank, probably because Bismarck's incomplete fuel load made a faster passage costly. Swedish reporting, Norwegian resistance information, and aerial reconnaissance had already given Britain a strong picture of the sortie. Lindemann and Brinkmann received the same alarming intelligence but could not draw Lütjens into the broader command discussion they wanted. The route decision therefore combined imperfect information with a command system that did not fully use the perspectives of both ship captains.
