Kapitänleutnant Siegfried Strelow after patrol

Siegfried Strelow began his naval career in April 1931. He served as torpedo officer on the battleships Schleswig-Holstein, Admiral Graf Spee and on the destroyer Richard Beitzen. He spent a year on E-boats (Schnellboot) S-9 and S-11 and then commanded the torpedo boat G-11 for a year.

During the war he commanded the torpedo boats Albatros and Löwe for six months each before serving as torpedo officer on the light cruiser Leipzig.

Having gained experience of almost every type of vessel in the Kriegsmarine, Strelow joined the U-boat force in April 1941.

He commissioned the type VIIC U-boat U-435 in August 1941, and despite lacking prior combat experience on U-boats went on to become one of the most experienced and successful commanders operating in northern and Arctic waters.

During six patrols in action against PQ and QP convoys he sank seven ships totalling some 35,000 GRT, for which he was awarded the Knights Cross. In January 1943 he moved base to Brest, France and was from then on attached to the 1st Flotilla. On her second patrol in the Atlantic U-435 was sunk with all hands by a British Wellington bomber on 9 July 1943. (Niestlé, 1998)
