Service history[]
U-70's first and only patrol began on 22 June 1940. Having sunk the Castleton near the Orkney Islands on the 28th and the Clearton about 180 mi (290 km) west of Ushant (often known as Ouessant, an island in northwest France)[1] on 1 July, she was herself sunk on the same day as the latter ship by depth charges from a British destroyer, HMS Vansittart. 43 men died with the submarine; there were no survivors.
After the U-boat's sinking, Vansittart rescued the 26 survivors from Clearton.
