The camp at North Coates Fitties was opened by the army in 1914 and occupied by men of the Lincolnshire Regiment. In 1916 it was converted into a forward landing ground for aircraft from the Royal Flying Corps' No. 33 (Home Defence) Squadron, based at Brattleby, and tasked with coastal patrols in North Lincolnshire. From October 1918 it was occupied by No. 248 Squadron RAF, but after the armistice the airfield was gradually run down and eventually closed in March 1919, and the land was returned to its original owner.
