L 33 dropped a few incendiaries over Upminster before losing its way and making several turns, heading over London and dropping bombs on Bromley at around midnight. As the bombs began to explode, the Zeppelin was hit by an anti-aircraft shell fired from the guns at either Beckton, Wanstead, or Victoria Park despite being at . Dropping bombs now to shed weight, a large number fell on homes in Botolph Road and Bow Road. As the airship headed towards Chelmsford it continued to lose height, coming under fire at Kelvedon Hatch and briefly exchanging fire with a B.E.2c. Despite the efforts of the crew, L 33 was forced to the ground at around 01:15 in a field close to New Hall Cottages, Little Wigborough. The airship was set alight and the crew headed south before being arrested at Peldon by the police. Inspection of the wreckage provided the British with much information about the construction of Zeppelins, which was used in the design of the British R33-class airships. One engine recovered from the wreck was subsequently substituted for two (of four) engines on a Vickers-built machine, the hitherto underpowered R.9.
