Lesson plan
HMS E40
HMS E40 was a British E-class submarine launched by Palmer, Jarrow in 1916 and was completed by Armstrong Whitworth, Newcastle upon Tyne. She was launched on 9 November 1916 and was commissioned in May 1917. During her World War I service while patrolling Scandinavian waters E40 encountered a U-boat. As the submarine dived the captain was hit with shrapnel and had to be dragged in; the hatch stuck and the vessel took on water, going straight to the bottom. After an hour the air was poor; with the captain unconscious, the first lieutenant asked the crew if he could use the remaining oxygen to try to raise the submarine. This succeeded and the E40 managed to get back to Middlesbrough where it had been posted missing, presumed sunk. The captain survived. HMS E40 was sold on 14 December 1921.
