World War II: German submarine U-29 sinks the British aircraft carrier HMS Courageous.
HMS Courageous was the lead ship of her class of three battlecruisers built for the Royal Navy during the First World War. Designed to support the Baltic Project championed by First Sea Lord John Fisher, the ship was very lightly armoured and armed with only a few heavy guns. Courageous was completed in late 1916 and spent the war patrolling the North Sea. She participated in the Second Battle of Heligoland Bight in November 1917 and was present when the German High Seas Fleet surrendered a year later.
Courageous was decommissioned after the war, then rebuilt as an aircraft carrier during the mid-1920s. She could carry 48 aircraft compared to the 36 carried by her half-sister Furious on approximately the same displacement. After recommissioning she spent most of her career operating off Great Britain and Ireland. She briefly became a training ship, but reverted to her normal role a few months before the start of the Second World War in September 1939. Courageous was torpedoed and sunk by a German submarine later that month, going down with the loss of more than 500 of her crew.
German submarine U-29 was a Type VIIA U-boat of Nazi Germany's Kriegsmarine during World War II.
She was laid down on 2 January 1936, launched on 29 August and commissioned on 10 November. During her career U-29 was involved in seven war patrols under the command of Kapitänleutnant Otto Schuhart.
