Aerial warfare was by no means a First World War invention. Balloons had already been used for observation and propaganda distribution during the Napoleonic wars and the Franco-Prussian conflict of 1870-1871. Planes had been used for bombardment missions during the Italo-Turkish war of 1911-1912. Yet, aerial warfare during the First World War marked a rupture with these past examples. It was the first conflict during which aircraft were involved on a large scale and played a significant role.
At the beginning of the war, the usefulness of air machines was met with a certain amount of skepticism by senior officers on all sides. In fact, aeroplanes were mostly involved in observation missions during the first year of the conflict. However, rapid progress enhanced aeroplanes’ performance. In 1915, the Dutch aircraft manufacturer Anthony Fokker, who was working for the Germans, perfected a French invention allowing machine-gun fire through the propeller. This discovery had a revolutionary consequence: the creation of fighter aircraft. This type of plane gave an edge to the Germans during 1915.
Their air superiority was to last until April 1916, two months after the beginning of the battle of Verdun. Thereafter, Allied dominance was gained through the creation of French fighting squadrons and the expansion of the British Royal Flying Corps. The control of the sky was to change hands again in the first half of 1917 when the Germans reformed their squadrons and introduced modern fighters. During April 1917, nicknamed ‘bloody April’, the British suffered four times more casualties than the Germans. But things were on the move on the Allied side. Successful reorganisations in France and Britain brought back air control for good until the Armistice.
During 1915, another important step was taken when the Germans organised strategic bombing over Britain and France by Zeppelin airships. In 1917-18 ‘Gotha’ and ‘Giant’ bombers were also used. This new type of mission, targeting logistic and manufacturing centres, prefigured a strategy commonly adopted later in the century. Inevitably, bombardments of ports and factories were quickly adopted by all sides and led to civilian deaths.
