Having first served with the Royal Engineers, Leslie Hamilton scored 6 victories flying the S.E.5a in Salonika in 1918. He relinquished his temporary and short service commissions at his own request, leaving the Royal Air Force on 28 November 1919. Post-war he became a commercial stunt flyer and was called the "Flying Gypsy."
On the morning of 31 August 1927, Hamilton and Colonel Frederick F. Minchin departed Upavon with their 63 year old passenger and financier, Princess Lowenstein-Wertheim, on an ill-fated trans-Atlantic flight from England to Canada. Hours later their Fokker Jupiter monoplane, the St. Raphael, was seen over coast of Ireland heading out to sea. The plane was last reported flying west over the mid-Atlantic by the crew of the Josiah Macy, a Standard Oil steamer. Hamilton and his companions were lost at sea and never found.
