Instead of attacking the Allied convoys singly, U-boats were directed to work in wolf packs (Rudel) coordinated by radio. In early 1941, the problems were determined to be due to differences in the earth's magnetic fields at high latitudes and a slow leakage of high-pressure air from the submarine into the torpedo's depth regulation gear. [44] Bismarck nearly reached her destination, but was disabled by an airstrike from the carrier Ark Royal, and then sunk by the Home Fleet the next day.

However, the combined assault by air, surface, and submarine forces failed to force Britain to surrender. As an island country, the United Kingdom was highly dependent on imported goods. It was both the largest armoured clash and the costliest single day of aerial warfare in history. This was in stark contrast to the traditional view of submarine deployment up until then, in which the submarine was seen as a lone ambusher, waiting outside an enemy port to attack ships entering and leaving. Some British naval officials, particularly the First Lord of the Admiralty, Winston Churchill, sought a more 'offensive' strategy. [103], Historians disagree about the relative importance of the anti-U-boat measures. a) the pursuit of higher education. A Catalina from 209 Squadron took over watching the damaged U-boat until the arrival of the armed trawler Kingston Agate under Lt Henry Owen L'Estrange. Instead, the London Naval Treaty required submarines to abide by "cruiser rules", which demanded they surface, search[21] and place ship crews in "a place of safety" (for which lifeboats did not qualify, except under particular circumstances)[22] before sinking them, unless the ship in question showed "persistent refusal to stopor active resistance to visit or search".
