Cudemore was transferred from the Shropshire Light Infantry as a second lieutenant on 21 June 1915. He opened his victory roll when he and Robert Hall shot down an observation balloon on 7 May 1917. Cudemore then promptly shot down another balloon single-handed.

He became an ace on 3 September 1917. He was promoted from temporary second lieutenant to temporary lieutenant effective 1 July 1917.
He continued to score through 9 November 1918. A summary of his final results is he destroyed three enemy fighter planes and two observation balloons, and drove down ten enemy planes out of control.
On 8 March 1925, he was appointed flying officer in the Royal Air Force. Also in 1925, he was sued for divorce by Carolyn Alice Cudemore.
