Hans Trojer after joining the Kriegsmarine

Hans-Hartwig Trojer joined the Kriegsmarine in 1936, and was part of the Olympia Crew. Because he was born in Transylvania, he was soon nicknamed Count Dracula by his comrades.

In October 1938 he joined the U-boat force, and he spent the first two years of the war as Watch Officer on U-34 and U-67.

After completing commander training, Trojer took over command of the school boat U-3. In March 1942 he commissioned the combat boat U-221.

His first patrol in the North Atlantic was so successful (six ships totalling 29,682 tons), that he and his crew were mentioned in the daily Wehrmachtsbericht (Armed Forces bulletin). He was awarded the Knights Cross via radio during his third patrol in March 1943.

On 8 Dec 1942 Trojer's boat accidentally rammed U-254 while the boats were on convoy operations in the North Atlantic. U-254 went down immediately with all but four of her crew (41 dead, including the Commander). U-221 herself was seriously damaged and unable to dive. Trojer abandoned the patrol and made for St. Nazaire, France, reaching base on 23 Dec. He was later absolved of any blame for the accident (Blair, 1998).

Kapitänleutant Trojer died with his entire crew on 27 September 1943 when a British Halifax sank U-221 in the Atlantic south of Ireland (Niestlé, 1998).
