21 July 1914

By mid-July 1914 the prospect of war with Germany and her allies became inevitable and the Royal Flying Corps began to mobilize in order to provide aerial support for the proposed British Expeditionary Force to France. The BE2a machines of 4th Squadron's 'A' and 'B' flights moved to Eastchurch on 21 July 1914 to support the RNAS in home defence during mobilization.
