12-03-1918  D3 was sunk in error in Channel by a French airship

D3 left Gosport on 7th March 1918 for an anti-submarine patrol in the English Channel. Little is known of her patrol movements but it is believed that a submarine spotted by a Royal Naval Air Service airship on the 11th was D3. On the 12th March the French airship AT-0 was patrolling when at 1420 a vessel was spotted to her north east. The airship drew close for recognition purposes and according to her commander, the submarine fired rockets at her. Four 52-kilo bombs were dropped by the airship. The submarine disappeared but several minutes later men were seen in the water. Attempts were made by the airship to rescue the men but it proved too difficult. The airship withdrew to seek help but all the men had drowned by the time it arrived. It is clear that D3 was the victim of a serious identification error on the part of the French airship, with identification rockets being mistaken for aggressive gunfire.
