He was a Sub-Lieutenant in the Royal Navy Volunteer Reserve. Later he joined the Royal Naval Air Service.
Before obtaining his age of majority he sailed from Liverpool to Vancouver, around Cape Horn, serving as a sailor before the mast. Later he crossed the Atlantic on board a three-masted schooner yacht Karina as one of the guests of Robert E. Todd of the New York Yacht club. He was a noted big game shot.
Prior to joining 2 (Naval) Squadron, Royal Naval Air Service at Eastchurch, he distinguished himself serving with the R.N.A.S. Armoured Car Division, with his armoured motorcar in helping to check the advance of the Germans on Brussels and in the defence of Antwerp.
Lord Annesley was last seen alive on 6 November 1914 leaving Eastchurch, England, in a Bristol T.B.8 biplane, serial 1220, flown by Flight Lieutenant C.F. Beevor, R.N.A.S., bound for France / Flanders. They were never seen again. His death was presumed on 2 December 1914 by Mr. Justice Astbury. Two German prisoners had been interrogated and it was established that the two aviators had been shot down when a German shell had hit the petrol tank of their aircraft and it had fallen in flames near Diksmuide.[1]
