He underwent basic military training in the 2nd company of the 7th standing ship department of the Baltic Sea in Stralsund (1 October 1938 – 27 February 1939).[Tr 1][Tr 2] Sieder was then transferred to the training ship Gorch Fock (28 February 1939 – 1 July 1939) and attained the rank of Seekadett (midshipman) on 1 July 1939. He then boarded Schlesien (2 July 1939 – 14 October 1939) for further ship based training. He then took the main cadet training course at the Naval Academy Mürwik in Flensburg-Mürwik (15 October 1939 – 1 March 1940). During this training period he advanced in rank to Fähnrich zur See (officer cadet) on 1 December 1939.
In January 1942, he became first watch officer on the newly commissioned U-440 and served on four patrols. He left U-440 in April 1943 just one month before U-440 was sunk; and commissioned the Type VIIC U-boat U-984 in June 1943.
