German submarine U-69 (1940)
German submarine "U-69" was the first Type VIIC U-boat of Nazi Germany's "Kriegsmarine" during World War II. This meant that compared to previous U-boats, she could travel further afield for longer, with a payload of eleven torpedoes, an deck gun for smaller vessels and a flak gun for use against aircraft. "U-69" was very successful, sinking over of Allied shipping in a career lasting two years, making her one of the longest surviving, continuously serving, U-boats. Her most notable attack was on the civilian ferry , which sank off the coast of Newfoundland  in October 1942, killing 137 men, women and children. She was rammed and sunk by on 17 February 1943. Design and construction. German Type VIIC submarines were preceded by the shorter Type VIIB submarines. "U-69" had a displacement of when at the surface and while submerged. She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . While on the surface the submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of ; while two AEG GU 460/8–27 double-acting electric motors producing  a total of were use when the submarine was submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to . The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . "U-69" was fitted with five torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one SK C/35 naval gun, 220 rounds, and one C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty sailors . She was built at the Germaniawerft in Kiel during 1940, and was ready for service in November. After her warm up in the Baltic Sea (designed to give her an opportunity to train and repair minor faults), she was deployed into the Atlantic Ocean in February 1941. Service history. First patrol. "U-69" departed Kiel for her first patrol on 10 February 1941. Her route took her across the North Sea, through the gap between the Faroe and Shetland Islands and into the Atlantic Ocean. She encountered the southwest of the Faroe Islands on 17 February and sank her. No survivors  were picked up, even though the crew were seen to reach the lifeboats. The boat was attacked twice by a Sunderland flying boat on the 22nd – no damage was sustained. "U-69"s next victim was "Empire Blanda", sunk on the 19th. Four days later (on the 23rd), "Marslew" was similarly destroyed, north northwest of Rockall. 13 men died, there were 23 survivors. The submarine was depth charged for three hours by the escorts of convoy OB 288 on 24 February. She escaped without any damage and docked at Lorient on the French Atlantic coast on 1 March. Second patrol. The boat 's second foray was to the mid-Atlantic. She sank "Coultarn" southwest of Iceland on 30 March. She then attacked and damaged "Thirlby", which had been "en route" from St. Johns, Newfoundland to Hull. The ship had also probably been hit by a torpedo fired by . This weapon was a dud. (The ship was further damaged by a bomb from a German aircraft on 10 April). "U-69" returned to Lorient on 11 April. Third patrol. The boat's next sortie was to the West African coast. She laid mines off Lagos and Takoradi and made full use of the failure  of the allies to enforce convoy systems. One of her victims was the neutral American ship operating off the British port of Freetown, Sierra Leone. The sinking of "Robin Moor" caused President Roosevelt to brand Germany an "international outlaw" and to require Germany and Italy to close all of their consulates in the United States except for their embassies. Before the sinking, "Robin Moor"s passengers and crew were allowed thirty minutes to board lifeboats, then the submarine torpedoed, shelled and sank the ship. The survivors then drifted without rescue or detection for up to eighteen days. When news of the  sinking reached the US, few shipping companies felt truly safe anywhere. As "Time" magazine noted in June 1941, "if such sinkings continue, US ships bound for other places remote from fighting fronts, will be in danger. Henceforth the US would either have to recall its ships from the ocean or enforce its right to the free use of the seas." In October 1941, federal prosecutors in the espionage case against a group of 33 defendants known as the "Duquesne Spy Ring" adduced testimony that Leo Waalen had submitted the sailing date of "Robin Moor" for radio transmission to Germany, five  days before the ship began her final voyage. Waalen was found guilty and sentenced to 12 years in prison for espionage and a concurrent 2-year term for violation of the Foreign Agents Registration Act. "U-69" also sank "Tewkesbury" about south of the Cape Verde Islands on the same date (21 May). Her master was awarded the OBE for his actions, but never knew about it; he was lost when "Newbury" went to the bottom on 15 September. She then sank "Sangara" in Accra harbour on 31 May 1941. The ship went down in of water, her bow was still  visible. (The vessel was salvaged in 1943 and her cargo sold, she was broken up in 1947). "Robert Hughes" was lost to a mine laid by "U-69" on 4 June. The submarine sank "River Lugar" southeast of the Azores on 27 June 1941 and "Empire Ability" on that same day. On the return journey, "U-69" was engaged in what was an ultimately successful gun-duel with "Robert L. Holt" southwest of the Canary Islands on 3 July 1941. She fired 102 high explosive and 34 incendiary rounds from her deck gun, 220 rounds from her 20mm anti-aircraft weapon  and 400 rounds from her MG 34 machine gun at the merchantman. The boat returned to France, to St. Nazaire on 8 July. Unfortunately for the crew of "U-69", it was nearly a year before they sank another ship, due to the tightening of convoys in the second half of 1941 and some frustratingly short patrols, called off because of mechanical failure or sickness on the boat. Fourth and fifth patrols. Patrol number four was relatively short, lasting barely a week and hardly leaving the Bay of Biscay. "U-69"s fifth patrol took her northwest of St. Nazaire towards Greenland; although  longer, it was also unsuccessful. Sixth and seventh patrols. The boat's sixth patrol was uneventful. During her seventh outing, she was depth charged for several hours by escorts of a convoy on 21 March, west of Ireland. She escaped without any damage. Eighth patrol. "U-69" added to her tally when she sank the tiny four-masted sailing vessel "James E. Newson" off the United States' seaboard with her guns. She sank a further three ships that month, making use of the "Second Happy Time" to add to her score. On one of them, "Lise", the first mate, the Norwegian  Hangar Lyngås, survived a total of four torpedoings. Ninth patrol and SS "Caribou". Easily the most controversial action by "U-69" was the destruction of the civilian ferry in the Cabot Strait at 3:21 a.m. Atlantic Summer Time, on 14 October 1942. The submarine had been in the area for a few days, and sank the SS "Carolus" the day before, with the loss of eleven lives. Early that morning, "Caribou" was spotted, primarily because her coal-fired steam boilers emitted a long solid black smoke trail, and was silhouetted against the phosphorescent sky. While sitting in wait on the surface , Gräf launched one torpedo, which hit. The stricken vessel's boilers exploded soon after being hit, and the ship sank in approximately five minutes, trapping most of the crew and passengers in the ship. "Caribou" departed North Sydney, Nova Scotia, on 13 October 1942, heading for its home port Port aux Basques in Newfoundland. She made this trip three times a week as part of the SPAB convoy series (SPAB for Sydney-Port aux Basques) organized by . The one-ship coastal convoy was escorted by , a . Controversy surrounded HMCS "Grandmère"s actions immediately after the sinking in the local Cape Breton  Island media. Instead of searching for the survivors right away, she engaged the U-boat in combat, almost ramming her, and firing off six depth charges. "Grandmère" pursued "U-69" for close to two hours, then turned back to look for survivors. During this time, some survivors of the sinking died from exposure in the cold Atlantic. As noted in a dispatch a few weeks later by the Flag Officer of the Newfoundland Force, Commodore H. E. Reid, "Grandmère" was following normal operational doctrine by going after the submarine, and not stopping to pick up survivors. If she had stopped, she  would likely have been sunk as well by "U-69". In all 57 military personnel, 31 merchant seamen and 49 civilians — including many women and children — were killed in the sinking, totalling 137 persons lost (most were trapped in the ship, and drowned). The sinking was also one of the few times that military censorship was immediately lifted, in an attempt to prevent rumours and speculation. The sinking made news across North America that week and was used effectively as a rallying cry for Victory Bond campaigns. The sinking was possibly the most significant in Canadian and Newfoundland waters, not because  of "Caribou"s tactical importance; but rather, the U-boat war was on display to Canadians and Newfoundlanders on their home front. Tenth patrol and loss. On 17 February 1943, while operating with wolf-pack "Haudegen", "U-69" was involved in an attack on convoy ONS 165 in the middle of the North Atlantic. Located by HF/DF and radar, she was forced to the surface by depth charges and then rammed by the destroyer . None of her 46 crew survived the sinking. Emblem. "U-69" was unusual in that she had two ships' emblems. The first, adopted on commissioning, was chosen by  her first commander, Metzler. This consisted of the word "Horrido" (Tally-Ho) and the three two-flag signal groups for the letters L M A (, a reference to Gotz von Berlichingen’s famous retort). The second came about when the 7th flotilla adopted Prien's bull emblem as its flotilla insignia. "U-69"s new first officer, who had not seen the insignia before, found a picture of a cow on a French cheese box, and had that painted on the conning tower, complete with the motto on the box "" (the laughing cow). When Metzler saw it, he decided to keep it , as it raised a laugh with all who saw it, and the crew adopted the slogan as a war-cry; "U-69" thereafter became known as the "laughing cow". Wolfpacks. "U-69" took part in seven wolfpacks, namely:
