Service history
HMS E12 became trapped in anti submarine nets in the Dardanelles. Her forward hydroplanes became entangled which sent her down to 245 feet. At the time, it was the greatest depth achieved by any British submarine. E12 managed to surface only to come under fire by shore batteries. She avoided further damage.

HMS E12 was sold in Malta on 7 March 1921.
