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-69s 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: Seewolf (4 – 15 September 1941) Brandenburg (15 – 24 September 1941) Störtebecker (5 – 19 November 1941) Gödecke (19 – 25 November 1941) Letzte Ritter (25 November – 3 December 1941) Falke (8 – 19 January 1943) Haudegen (19 January – 15 February 1943) Summary of raiding history References Bibliography External links German Type VIIC submarines World War II submarines of Germany Ships built in Kiel 1940 ships U-boats commissioned in 1940 U-boats sunk in 1943 U-boats sunk by British warships U-boats sunk by depth charges Ships lost with all hands World War II shipwrecks in the Atlantic Ocean Maritime incidents in February 1943
