Gurdon was seconded to the Royal Flying Corps in May 1917, and was confirmed in his rank of the General List on 10 August 1917. He completed his pilot training at Central Flying School and was sent to No. 22 Squadron in 1918, flying Bristol F.2 Fighters. Gurdon achieved all twenty-eight of his victories between 2 April and 13 August 1918 while flying the Bristol Fighter aircraft, seventeen of them using the front gun. On 7 May he was involved in an historic engagement known as the "Two versus Twenty". Gurdon, together with his observer 2nd Lt. John Thornton, in partnership with one other Bristol Fighter aircraft, piloted by Alfred Atkey with his observer Charles George Gass engaged twenty enemy aircraft. Gurdon and Thornton shot down three enemy aircraft; Atkey and Gass shot down five. As a result of this action he was awarded the Distinguished Flying Cross, which was gazetted on 2 August. His citation read: On 10 July his aircraft was badly shot up, Gurdon being hit by a bullet in the left arm, and his gunner, Lt. J. J. Scaramaga, being killed. He was appointed a flight commander with the rank of temporary captain on 23 July, but in August he received a concussion from an anti-aircraft shell near-miss. He was returned to the UK in September and relinquished his commission owing to his injuries on 21 December, but was permitted to retain the rank of captain. His confirmed claims, in conjunction with his gunners, consisted of 13 and one shared aircraft destroyed, and 14 driven down 'out of control'.
Interwar career
After the war Gurdon pursued a career as a journalist and author, publishing his first novel Over and Above in 1919, republished in 2018. He then translated Georg Paul Neumann's Die Deutschen Luftstreitkräfte im Weltkriege, an official history, which was published in English as The German Air Force in the Great War in 1921. Another novel Feeding The Wind was published in 1924. However, in December 1925 he was declared bankrupt. and over the next fifteen years, to pay off his creditors, Gurdon wrote several novels, and numerous short stories, mainly adventure stories aimed at young adults, and published in such magazines as The Modern Boy and Air Stories. He finally gained his discharge from bankruptcy in late 1937, but continued to publish regularly up to the outbreak of the Second World War.
Despite being blinded in one eye after a car crash in 1935 and suffering a hip problem following an aircraft landing accident, Gurdon joined the Royal Air Force Volunteer Reserve, and was granted a commission "for the duration of hostilities" as a pilot officer on 20 September 1940. He served as an instructor and managed to fly on several bombing operations unofficially as a front gunner on Wellingtons, but after a landing accident aggravated his existing hip problem he was forced to relinquish his commission on 29 September 1941.
Later life
He published two more novels in the early 1950s. John Gurdon died on 14 April 1973 in Alassio, Italy.
