Damage, fuel, and repair capacity drove Bismarck toward France

A shell hit had left Bismarck down by the bow, severed fuel lines, opened tanks to seawater, and reduced the ship's practical top speed. Because Lütjens had not topped up in Norway, the contaminated and inaccessible fuel made every route calculation more severe. He believed the shadowing force was driving him toward Nelson and Rodney waiting ahead, although Rodney was still searching for him. Lindemann argued for the shorter return through Denmark Strait to Norway after having urged an aggressive pursuit immediately after battle. Lütjens rejected that course because it passed close to concentrated British coastal air and sea forces and because French yards were more likely to restore Bismarck to service. He also tried to assemble U-boats south of Greenland against the presumed shadowers, one reason he continued sending operational information. Fuel endurance, repair capacity, assumptions about British deployments, and the proposed submarine attack all affected the choice.
