later picked up by , but the master, 31 crewmen, and two gunners were lost. The U-boat had her third success of the day at 20:37, sinking the 5,086 GRT Belgian merchant ship Gand. One crew member was lost and another wounded. The master, 38 crewmen and four gunners were rescued. Ten days later, on 20 May, the wolfpack attacked Convoy HX 126. Between 14:48 and 15:16 U-556 fired torpedoes at the convoy and sank two British merchant ships, the 4,974 GRT Darlington Court and the 5,995 GRT Cockaponset, and the 8,470 GRT tanker British Security. Loaded with 11,200 tons of benzine and kerosene, the tanker caught fire and burned for three days before sinking. There were no survivors from her crew of 53. The sinking of Bismarck On 26 May, while returning from patrol, low on fuel and having fired all her torpedoes, U-556 was ordered to reconnoitre the most recently reported position of the battleship . U-556 and Bismarck had been neighbours in the ways at Blohm & Voss and their construction was completed at about the same time. (Bismarck was commissioned on 24 August 1940.) In January 1941, as U-556s commissioning ceremony approached, Wohlfarth wanted a band for the celebration, but could not afford to hire one. Kapitän Ernst Lindemann, commanding officer of Bismarck, lent him his ship's band. As thanks, Wohlfarth drew up a humorous Patenschaftsurkunde ("Certificate of Sponsorship") promising that U-556 would protect Bismarck. A drawing shows Wohlfarth as the knight Parzival [Percival] (his nickname) on the deck of U-556 simultaneously bringing down planes with a sword and reaching underwater to stop a torpedo with his thumb. A second drawing then shows the submarine towing the battleship to safety. The text accompanying the drawing reads: Around 19:50, Wohlfahrt saw the battlecruiser and the aircraft carrier coming out of the mist at high speed. He recorded in his log, "Enemy bows on, 10 degrees to starboard, without destroyers, without zigzagging," but without any torpedoes, could only submerge and avoid them. Wohlfahrt saw activity on Ark Royals flight deck, which transpired to be the launching of the second, fatal attack on Bismarck. At 20:39, Wohlfahrt surfaced and transmitted, "Enemy in view, a battleship, an aircraft carrier, course 115, enemy is proceeding at high speed. Position 48° 20′ N, 16° 20′ W." Renowns and Ark Royals course toward Bismarck coincided almost exactly with his own; he proceeded on
