U 984 was a German type VII C submarine that was used by the former German Navy during World War II. The boat was part of the 9th submarine flotilla in Brest . The commandant was Lieutenant Heinz Sieder.
commander
Heinz Sieder was born on June 28, 1920 in Munich and joined the Navy as an officer candidate in autumn 1938 . He was thus a member of Crew 38 , the officer class of that year. After training on board the Gorch Fock , he was promoted to midshipman the following year . The further on-board training on the liner Silesia was followed by the main course for ensigns at the naval school in Flensburg - Mürwik . This was ended on December 1, 1939 with the promotion to ensign at sea . Heinz boiler was in August 1940 for Midshipman and in the spring of 1941 to lieutenant promoted. At the turn of the year 1941/1942 he took part in the building instruction for U 440 , on which he drove under commandant Hans Geißler until spring 1943 as 1st WO. On April 1, 1943, Heinz Sieder was promoted to lieutenant in the sea and in June of the same year took command of U 984 .
history
The class VII C submarine was laid down on September 7, 1942 in the Hamburg shipyard Blohm & Voss . After training trips with the 5th U-Flotilla , the boat left Kiel on December 30, 1943 for transfer to Brest, where it arrived on February 24, 1944. From there it undertook a total of four patrols.
Operation Neptune
During the operation against the Allied invasion fleet from June 6 to 10, 1944, the boat fought its first skirmishes with destroyers, shot several torpedoes at them, was shot at with anti-aircraft weapons and pursued with depth charges. The torpedo hits on a destroyer reported by Commander Sieder could never be proven. During a further mission from June 12 to 19, 1944, U 984 fired on a frigate with the identification A 466 on June 13, 1944 without success. Due to the large number of enemy ships, it could only continue its journey with a snorkel . This device made it possible to operate the submarine's diesel engines - since exhaust air is guaranteed - also under water, which in turn can be used to recharge the boat's electric motors. The large number of Allied ships that were at sea in the course of Operation Neptune and the additionally increased air surveillance made it impossible for U 984 to achieve a sufficiently long "snorkeling time". The boat finally had to call at St. Peter Port on Guernsey due to empty batteries . Here the boat was bombed by fighter bombers . Bombs hit the harbor basin near the boat, but U 984 was not damaged.
Convoy battle against EMC17
The operation was continued on June 21, 1944 from St. Peter Port. On June 25, 1944, U 984 damaged the British destroyer Goodson (1,300 t). Commander Sieder reported the ship as sunk, but in fact the destroyer was towed by another British ship and towed to Portland. When approaching the convoy EMC17 on June 29, 1944 , U 984 also damaged the American ships Henry G. Blasdel (7,176 GRT) ( location ), James A. Farell (7,176 GRT) ( location ) and John A. Treutlen (7,176 GRT) ( Location ) so sustainable that all three steamers had to be abandoned by the crew and declared a total loss. In addition, U 984 damaged the Edward M. House (7,240 GRT) . In the course of the return voyage, U 984 was fired at by an unidentified ship with machine weapons on July 1, 1944 and reached its home port of Brest on July 5. On the basis of the success reports, Commander Sieder was awarded the Knight's Cross of the Iron Cross on June 8th . At that time, the high command of the Navy had recognized two destroyers, a frigate and three steamers (with 24,000 GRT) as sinking successes.
Whereabouts
U 984 left Brest on July 26, 1944 . The Bay of the Seine was intended as the operating area. On August 16, however, the submarine command ordered the trip to be aborted and returned to Brest. From this point on, no further contact could be made with U 984 . According to allied sources, the boat was sunk on August 20, 1944 by the Canadian destroyers Ottawa , Kootenay and Chaudiere in front of the port entrance of Brest ( Lage ).
