He began his military service in the
Royal Warwickshire Regiment, being commissioned as a temporary second lieutenant on 26 August 1915. Price volunteered for aviation duty and undertook pilot's training. On 28 November 1916, he was appointed a
flying officer; this appointment signified his qualification as a pilot. He was seconded from the
Royal Warwickshire Regiment to the
Royal Flying Corps for duty. He was one of the founding members of
No. 48 Squadron RFC, and served with them piloting a two-seater
Bristol F.2 Fighter. Price became a
flying ace during
Bloody April, 1917; British aviation suffered their heaviest casualties of World War I during that month. He scored two further victories on 9 May 1917, only to be shot down in turn by
Lothar von Richthofen. Despite being wounded, he managed to land his aircraft in friendly territory north-east of
Fampoux, France. On 1 July 1917 he was promoted to lieutenant, and was awarded the
Military Cross for his gallantry on this occasion, which was
gazetted on 18 July 1917: :"For conspicuous gallantry and devotion to duty. His machine being disabled by hostile fire, and his gun out of action, he managed by skilful handling to effect a safe landing, thus saving the machine and his passenger from capture. He has previously done fine work against hostile aircraft." On 1 March 1918, Price was appointed a
flight commander with the accompanying temporary rank of captain, and transferred to the
General List of the RFC. ==List of aerial victories==
