@Walter Hinteler,
Strategic bombing was used in World War I, though it was not understood in its present form. The first bombing of a citywas on the night of 24–25 August 1914, when eight bombs were dropped from a German airship onto the Belgian city of Antwerp.
The Royal Naval Air Service (RNAS) undertook the first Entente strategic bombing missions on 22 September 1914 and 8 October, when it bombed the Zeppelin bases in Cologne and Düsseldorf.
On November 21, 1914, he RNAS flew across Lake Constance to bomb the Zeppelin factories in Friedrichshafen

When WW1 started in August 1914 the Zeppelin was perceived as being a significant threat. It could fly higher, faster, further, had a greater rate of climb and carry a greater payload than any aircraft of the day.
Concerns about possible Zeppelin attacks were taken seriously by the Britishgovernment, even as early as 1908. While no one expected an invasion force to disembark from the airships, the idea that the Zeppelins could be loaded with explosivesand flown over England to “pour death into one town after the other” was widely believed, according to the
San Francisco Sunday Call.
Churchill had become First Lord of the Admiralty in October 1911, and saw the potential of aircraft beyond the limited view of the Military Wing. In October 1913 he wrote a paper describing how Britain needed fighter aircraft for its defence, and bombers to attack the Zeppelins.
