The Imperial German Navy Zeppelin LZ 48 (L 15) was a P-class World War I zeppelin.

Operational history edit

The Airship took part in eight reconnaissance missions with three attacks on England dropping 5,780 kg (12,740 lb) of bombs.

Destruction edit

The Zeppelin was damaged by ground fire from Dartford AA battery^[1] during a raid on London on 1 April 1916. The airship came down at Kentish Knock Deep in the Thames estuary. One crew member was killed; the other 17 were taken prisoner of war after being picked up by ships.^[2] The gunners at Purfleet attempted to claim a prize of £500 offered by the Mayor of London for shooting down the Zeppelin, but the War Office declared them ineligible.^[3] Instead the gunners received a gold medal.
