Mortal Hit on the Bismarck

German Battleship Bismarck's Atlantic Sortie, May 1941.

In the wake of the successful January-March 1941 cruise of the battleships Scharnhorst and Gneisenau against Allied shipping, and in keeping with Grand Admiral Erich Raeder's strategy of aggressively employing his heavy ships, another German Navy raiding expedition into the Atlantic was undertaken, employing the new battleship Bismarck and heavy cruiser Prinz Eugen. After many delays, these ships left the Baltic Sea on 19-20 May. Briefly stopping near Bergen, Norway, on 21 May, they then headed north, planning to enter the shipping zone by way of the Denmark Strait, between Iceland and Greenland.

British planes had photographed the German ships while they were in Norwegian waters, and the Royal Navy sent its own warships to sea in an effort to intercept the enemy and keep him from attacking the vital convoys. British cruisers began to shadow the Germans on 23 May, and Bismarck fired on HMS Norfolk. At about 6AM the next day, in the Battle of the Denmark Strait, the Germans fought and destroyed HMS Hood and drove off HMS Prince of Wales.

Bismarck was also damaged sufficiently to force her to abort her mission. British aircraft and ships continued to follow the two German vessels, which separated late on 24 May during an exchange of gunfire with their pursuers. Prinz Eugen continued into the Atlantic while Bismarck was to head toward France, where her damage could be repaired. That night, the British hit the German battleship with a carrier plane's torpedo, reducing her speed, but also lost track of her. Contact was regained on the 26th and the Royal Navy vectored its ships to attempt to sink Bismarck before she could reach the protection of Luftwaffe aircraft from France. Late that day, planes from the carrier Ark Royal scored at least two torpedo hits, one of which crippled Bismarck's rudders.

Unable to maintain course toward France, and still out of range of friendly airpower, Bismarck now was at the mercy of her enemies. Torpedo attacks by destroyers on 26-27 May achieved no success, but on the morning of the 27th two Royal Navy battleships, Rodney and King George V, and two heavy cruisers arrived. Firing began before 9AM, with German gunfire accuracy quickly degrading to ineffectiveness. British fourteen and sixteen-inch shells gradually smashed Bismarck's main guns, superstructure, hull and armor. Prompted by torpedoes and scuttling charges, the German battleship rolled over and sank somewhat after 10:30 AM on 27 May 1941, bringing to an end the most serious challenge that German surface warships would make to British Atlantic Ocean supremacy.
