German bombing of Britain, 1914–1918

A German air campaign of the First World War was carried out against Britain. After several attacks by seaplanes, the main campaign began in January 1915 with airships. Until the Armistice the Marine-Fliegerabteilung (Navy Aviation Department) and Die Fliegertruppen des deutschen Kaiserreiches (Imperial German Flying Corps) mounted over fifty bombing raids. The raids were generally referred to in Britain as Zeppelin raids but Schütte-Lanz airships were also used.

Weather and night flying made airship navigation and accurate bombing difficult. Bombs were often dropped miles off target (a raid on London hit Hull) and hitting military installations was a matter of luck. Civilian casualties made the Zeppelins objects of hatred. British defensive measures made airship raids much riskier and in 1917 they were largely replaced by aeroplanes. The military effect of the raids was small but they caused alarm, disruption to industrial production and the diversion of resources from the Western Front. Concern about the conduct of the defence against the raids, the responsibility for which was divided between the Admiralty and the War Office, led to a parliamentary inquiry under Jan Smuts and the creation of the Royal Air Force (RAF) on 1 April 1918.

Airships made 51 bombing raids on Britain during the war in which 557 people were killed and 1,358 injured. The airships dropped 5,806 bombs, causing damage worth £1,527,585. Eighty-four airships took part, of which 30 were either shot down or lost in accidents. Aeroplanes carried out 52 raids, dropping 2,772 bombs of 73.5 long tons (74.7 t) weight for the loss of 62 aircraft, killing 857 people, injuring 2,058, and causing £1,434,526 of damage. The German bombing has been called, by some authors, the first Blitz, alluding to the Blitz of the Second World War. The defence organisation developed by the British foreshadowed the ground-controlled interception system used in the Second World War.
