The son of Benjamin and Eliza Highfield Jones, Philip was born in Wolverhampton in 1893. Some records have “Highfield” as his middle name, some as a double-barrelled surname, and some with both. In 1901, he was living with his parents and sister Gabrielle at The Poplars, Upper Penn, Wolverhampton. By 1911, Philip was a boarder at Berkhampstead School in Hertfordshire. He later attended Cambridge University and became a Cadet in their Officer Training Corps.
On 5 November 1914, the London Gazette announced that he had been made Second Lieutenant. Philip later became a Lieutenant and then a Captain (in May 1918) within the South Staffordshire Regiment. On 17 September 1917, the London Gazette announced that he had been awarded the Military Cross:
For conspicuous gallantry and devotion to duty. During an attack upon a village he was in command of a company of moppers-up. Two of the attacking companies having suffered heavily under machine gun fire, he took command of the remnants, and with great gallantry and determination cleared the enemy out of the houses which they had occupied, inflicting heavy casualties upon then, and capturing eight prisoners and three machine guns. He showed great initiative and resource in the way in which he handled a difficult situation.
Philip survived the war, and married Muriel V. Reed in Wolverhampton in 1931. He continued to serve with the Army, becoming a Major in 1930, and later a Colonel. Philip died in Cannock on 26 July 1951, and the value of his effects was £10498 7s. 2d.
