text: Wartime service Brown set sail for England on 22 November 1914 and underwent further training at Chingford. On 2 May 1916, Brown crashed his Avro 504 emerging apparently unscathed, though next morning he experienced severe back pain as he had broken a vertebra. He spent two months in hospital and in September 1916 was posted to Eastchurch Gunnery School. In January 1917, he was sent to Cranwell to complete advanced training.
  In March 1917, Brown was posted to No. 9 Naval Squadron, flying coastal patrols off the Belgian coast in Sopwith Pups. In April, "B" Flight, which included Brown, was attached to the Army's Royal Flying Corps to assist during the Battle of Arras. Brown fell ill at this time and missed "Bloody April", a period when British casualties were very high.
  In June 1917, Brown was posted to No. 11 Naval Squadron, and in July he was briefly posted to No. 4 Naval Squadron before returning to No. 11 Naval Squadron later that month. On 17 July, he achieved his first "kill", an Albatros D.III, while flying a Pup, and gathered another three unconfirmed kills.
  No. 11 was disbanded in mid-August 1917, and Brown returned to No. 9, equipped with the Sopwith Camel. He was promoted to flight lieutenant on 1 October, and on 6 October, Brown was awarded the Distinguished Service Cross (DSC). His citation read:
