Hardegen served for few months in the Torpedowaffenamt ("Torpedo Weapon Department") before becoming Battalion Commander in Marine Infanterie Regiment 6 from February 1945, taking part in the fighting around Bremen. He was the last surviving "Ace of the Deep", dying on 9 June 2018 at the age of 105. |
| Werner Hartenstein † | 5 | 19 | 97,489 | Hartenstein (1908–1943) commissioned U-156 in September 1941. On his second patrol, he attacked the refinery at Aruba with gunfire. On the fourth patrol, he was involved in the Laconia Incident. On his fifth patrol, on 8 March 1943, Hartenstein and his crew were killed when U-156 was sunk by depth charges dropped from a United States Navy PBY Catalina, east of the island of Barbados. |
| Werner Hartmann | 4 | 26 | 115,337 | Hartmann (1902–1963) was commander of both U-37 and the 2nd U-boat Flotilla from January–May 1940, but this proved inefficient, and BdU decided to direct the U-boats from land. After three patrols, Hartmann moved to the BdU staff. In November 1940, he became commander of 2. Unterseeboots-Lehr-Division ("2nd U-boat Training Division"), and a year later took command of the 27th U-boat Flotilla. In November 1942, he took command of U-198 for a patrol to the Indian Ocean lasting 200 days, the third-longest patrol ever undertaken, and sank seven ships totalling 36,778 GRT. In 1944, Hartmann became FdU Mittelmeer ("Commander of U-boats in the Mediterranean"). After the war, he served several years in the Bundesmarine. |
| Werner Henke | 7 | 24 | 155,714 | Henke (1909–1944) took command of U-515 in February 1942. U-515 was sunk by United States Navy aircraft and destroyers north of Madeira. Henke was taken to a secret interrogation centre known only as P. O. Box 1142 in Fort Hunt, Virginia, where his interrogator threatened to send him to England to face war crime charges if he did not cooperate. On 15 June 1944, Henke ran to the fence surrounding the interrogation centre and began to climb over. He ignored a guard's order to stop, and was shot and killed. |
| Günter Hessler | 3 | 21 | 118,822 | Hessler (1909–1968) commissioned U-107 in 1940, and on his first patrol sank four ships for a total of 18,514 tons. He became famous for his second patrol – the most successful of the entire war – sinking 14 ships for a total of 86,699 tons. His third patrol accounted for another three ships for a total of 13,641 tons. Hessler then transferred to the BdU to serve on the staff of his father-in-law Karl Dönitz. After the war, he testified at the Nuremberg trials. In 1947, Hessler was commissioned by the British Royal Navy to write The U-Boat War in the Atlantic. Assisted by Alfred Hoschatt, former BdU staff officer and commander of U-378, he completed the three-volume work in 1951. |
| Ulrich Heyse | 5 | 12 | 83,639 | (1906–1970) sailed on a single patrol on U-37 as Kommandantenschüler ("Commander-in-training"), before he commissioned U-128 in December 1941. He was an instructor from 1943, before taking command of the 32nd U-boat Flotilla in March 1945. |
| Hans Jenisch | 6 | 17 | 110,139 | Jenisch (1913–1982) took command of U-32 in early 1940. He sank 17 ships, including the 42,348 ton RMS Empress of Britain, the largest ship sunk by a U-boat.

In 1956, he joined the Bundesmarine, holding mainly staff positions, but also commanding the frigate Hipper for a few months. |
| Ernst Kals | 5 | 20 | 145,656 | Kals (1905–1979) took command of U-130 in June 1941. On 12 November 1942, during the Naval Battle of Casablanca he attacked the heavily guarded transport ships in Fedala Roads in Morocco, sinking three large troop ships for a total of 34,507 tons in five minutes. From January 1943 to the end of the war, he commanded the 2nd U-boat Flotilla. |
| Günther Krech | 10 | 19 | 100,771 | Krech (1914–2000) commissioned U-558 in February 1941, and sailed on ten patrols, mostly in the Atlantic and the Caribbean. U-558 was sunk by US aircraft on 20 July 1943 in the Bay of Biscay. Only five men – Krech, the engineering officer, and three men of the gun crew – survived. |
| Otto Kretschmer | 16 | 46 | 273,043 | Kretschmer (1912–1998) was the most successful of the World War II Aces of the Deep. As commander of U-35, U-23 and U-99 he sank 47 merchant ships in a remarkably short period of time, before being captured in March 1941 and spending the rest of the war in the Bowmanville POW camp, Canada. After the war, he rejoined the Bundesmarine, and became the Chief of Staff of the NATO Command COMNAVBALTAP in May 1965. He retired in September 1970 with a rank of Flottillenadmiral. During his time as a U-boat commander, he was given the nickname "The Tonnage King" because of his high GRT record. |
| Herbert Kuppisch † | 14 | 16 | 82,108 | Kuppisch (1909–1943) first commanded U-58, sailing on eight patrols between September 1939 and June 1940, and sinking four ships, including the British boom defence vessel HMS Astronomer. From August 1940, in command of U-94, he sailed on a further five patrols, and sank another 12 ships. From August 1941, he served on the staff of the BdU, before spending six months at the OKM. He finally returned to U-boats in July 1943, taking command of U-847. On 27 August 1943, only 30 days into her first patrol U-847 was sunk by aircraft from USS Card. There were no survivors. |
| Georg Lassen | 4 | 26 | 156,082 | Lassen (1915–2012) took command of U-160 and sailed on four combat patrols in 1942–43, sinking a remarkable average of 39,020 GRT per patrol.

| Heinrich Lehmann-Willenbrock | 10 | 25 | 179,125 | Lehmann-Willenbrock (1911–1986) commanded the U-8, U-5 and U-96. In May 1942, he took command of the 9th U-boat Flotilla, transferring to the 11th U-boat Flotilla in December 1944. After spending a year in captivity after the German surrender, he served as captain on merchant ships, and from 1964 commanded the German nuclear-powered freighter Otto Hahn. Willenbrock acted as advisor to the film Das Boot, based on an account of one of his own war patrols in U-96. |
| Fritz-Julius Lemp † | 10 | 20 | 96,639 | Lemp (1913–1941) commanded U-30 and U-110. His first attack, on 3 September 1939, only two days after the British declaration of war, was the most controversial. Lemp sank what he thought was an armed merchant cruiser, but was in fact the passenger liner SS Athenia; 112 of her passengers died. The sinking resulted in bad publicity throughout the English-speaking world, while the German High Command systematically attempted to cover up this error. Not until January 1946, during the Nuremberg Trials, did Admiral Dönitz finally admit that Athenia had been torpedoed by U-30. Lemp was killed in May 1941 when U-110, on her second patrol, was captured east of Cape Farewell, Greenland, by the British destroyers HMS Bulldog and HMS Broadway. |
| Heinrich Liebe | 9 | 34 | 187,267 | Liebe (1908–1997) commanded U-38 between 1938 and 1941, sinking 34 ships for a total of 187,267 GRT. In 1941 Liebe was assigned to the staff of Oberkommando der Marine, and from August 1944 was on the staff of the BdU. After the war, Liebe returned to his hometown in the Soviet sector. As he refused to train Soviet submariners, he was allowed only a series of menial occupations. |
| Wolfgang Lüth | 16 | 46 | 225,204 | Lüth (1913–1945) was given command of U-9 in December 1939, going on to command U-13, U-138, U-43 and U-181, and sinking 46 merchant ships for a total 225,204 tons in 15 patrols, including one of 205 days, the second longest of the war. In January 1944 Lüth took command of the 22nd U-boat Flotilla, before being appointed commander of the Naval Academy Mürwik in July. Lüth was mistakenly shot and killed by a German sentry on 13 May 1945. |
| Karl-Friedrich Merten | 5 | 27 | 170,151 | Merten (1905–1993) commanded U-68 on five patrols in 1941–42. He commanded the 26th U-boat Flotilla in early 1943, and this and other training appointments curtailed his operational career. |
| Karl-Heinz Moehle | 10 | 21 | 92,086 | Moehle (1910-1996) commissioned U-20 in October 1937, and in six wartime patrols, sank eight ships.

| Rolf Mützelburg | 8 | 19 | 81,961 | Mützelburg (1913–1942) served aboard U-100 under Joachim Schepke before commissioning U-203 in February 1941. In eight patrols, he sank 19 ships and damaged three more. On 11 September 1942, during his eighth patrol, Mützelburg was killed in a freak accident; diving off the conning tower into the sea southwest of the Azores, he struck the hull when the U-boat suddenly lurched in the swell. |
| Victor Oehrn | 4 | 23 | 103,760 | Oehrn (1907–1997) became commander of U-14 in January 1936, patrolling during the Civil War in July–September 1936. In August 1939, he joined the staff of BdU. In May 1940, Oehrn took command of U-37 in order to restore trust in the G7e/T2 torpedo, which had performed abysmally, often detonating prematurely or not at all. In four patrols he sank 23 ships for a total of 103,760 GRT before returning to the staff in August. From November 1941, Oehrn served on the Mediterranean U-boat staff, but during a mission to North Africa in July 1942, he was severely wounded and captured by the British. He was released in a prisoner exchange in October 1943 and returned to Germany. Oehrn spent the remainder of the war serving in several staff positions. |

His most famous exploit was infiltrating the British Home Fleet's base at Scapa Flow in October 1939 and sinking the battleship HMS Royal Oak, which won him the Knight's Cross of the Iron Cross, the first U-boat commander so honored. Prien was lost when U-47 went missing on 7 March 1941 during an attack on Convoy OB 293 south of Iceland. He was given the nickname "The Ace of Aces". |
| Wilhelm Rollmann † | 8 | 22 | 101,519 | Rollmann (1907–1943) took command of U-34 in October 1938. After seven successful patrols, Rollmann became an instructor in 2. Unterseeboots-Lehr-Division ("2nd U-boat Training Division"). He commissioned U-848 in February 1943, sailing on one patrol on 1 August 1943 and sinking one ship of 4,573 tons. Rollmann and his crew were killed on 5 November 1943 when U-848 was sunk by US aircraft south-west of Ascension in the mid-Atlantic. |
| Jürgen von Rosenstiel † | 4 | 14 | 78,843 | Rosenstiel (1912–1942) commanded U-502. On his fourth patrol, on 5 July 1942 U-502 was sunk by a British Wellington bomber in the Bay of Biscay. All of the crew were killed. |

From January to April 1940 he commanded U-19, sinking another nine ships. After a brief spell serving in a staff position, Schepke took command of U-100 in which he sank another 25 ships. On 17 March 1941, while attacking Convoy HX 112 U-100 was forced to the surface by depth charges from HMS Walker and HMS Vanoc, detected on radar, and consequently rammed by Vanoc. Schepke and 37 crewmen were killed; only six were rescued. |
| Georg Schewe | 10 | 16 | 85,779 | Schewe (1909–1990) commanded U-60 from July 1939, but in six patrols sank only one ship.
