The Navy attempted to follow up the Army's success the following night. Three Zeppelins were directed against London and one against the benzol plant at Skinningrove. L 11 turned back early with engine trouble; L 14 suffered the same problem while over Norfolk: its bombs were dropped on Dereham and the Zeppelin returned home. L 13 reached London, approaching over Golders Green, and "Kapitänleutnant" Heinrich Mathy began bombing around 22:40. The bomb-load included a device, the largest yet carried. This exploded on Bartholomew Close near Smithfield Market, destroying several houses and killing two men. Further bombs fell on the textile warehouses north of St Paul's Cathedral, causing a fire which despite the attendance of 22 fire engines caused over half a million pounds damage: Mathy then turned east, dropping his remaining bombs on Liverpool Street station. The Zeppelin was repeatedly caught by searchlights and all 26 anti-aircraft guns in London were active, but every shell exploded too low and the falling shrapnel caused both damage and alarm on the ground. Three aircraft were in the air. None even saw the Zeppelin; one crashed on landing, killing the pilot. The raid killed 22 people and injured 87: the monetary damage was over one sixth of the total damage inflicted by bombing raids during the war.
