Davies was born in Harrow, England, the first-born son of Mr. and Mrs. Arthur Davies.^[2]

On 17 October 1915, he was commissioned second lieutenant in the Wiltshire Regiment.^[3] On 20 November 1917, he was seconded to the Royal Flying Corps as a lieutenant^[4] and a flying officer.^[5]

By mid-1918, Davies was posted to 150 Squadron in Salonika as a Sopwith Camel pilot. He scored his first aerial victories on 12 June 1918, when he set one Albatros D.V afire and destroyed another. His second successful day saw him become an ace, as he destroyed two more Albatros D.Vs in one dogfight on 17 July, then drove another down out of control an hour and a half later. Six days later, he teamed with John Preston to destroy another. On 8 August, he drove down two enemy fighters out of control. Ten days later, he rounded off his victory string by driving down another pair of Albatros D.Vs out of control.^[1]

He earned the Distinguished Flying Cross for his prowess. It was announced in The London Gazette on 2 November 1918:

"This officer sets a fine example of gallantry and courage, notably on two occasions. On the 12th of June he, single-handed, engaged four enemy scouts, one of which he shot down in flames and a second out of control; the latter was seen to catch fire on reaching the ground. Some weeks later he led his patrol of four scouts against a formation of eleven hostile machines; two of these were shot down in flames, the wings fell off another, and the remainder dispersed."^[6]

He returned to Kuwait twice as a civilian, once in 1962 and once again in 1965.^[17] In 1966 during a "very tense meeting" that had "turned nasty" and "confrontational" between members of the Egyptian Air Force and members of the RAF in London, Davies told a group of Egyptian air force officers that if they went to war with Israel "they would lose and lose badly."^[18] In 1967 Davies was outspokenly supportive of Israel during the Six-Day War, and he advocated a closer relationship between Britain and Israel.^[19] During the Iran–Iraq War he warned against Britain arming Iraq, and he viewed the entire conflict as being potentially dangerous to Kuwait.^[20] After Saddam Hussein invaded Kuwait, Davies was strongly supportive of U.S. and British policy with regards to using force to remove Saddam Hussein's forces from Kuwait during the Gulf War.^[21]
