Grave unknown

Hugh was the son of Dr J B Terres. He was educated at Westminster School and Christ Church Oxford. On 26 May 1917, Hugh joined the Foreign Legion.

When he died he was an Ensign US Naval Reserve Force Class 5. Appointed from North Carolina. He served in France and Italy.

High was killed in flight - an American list says that he was killed in a seaplane accident with another ensign Alen F. Nichols.  His mother, Mrs C Terres of 35 Pembroke Road, Kensington was his next of kin. 

His name appears on a list of the Lafayette Flying Corps who have their Memorial at Marnes-La-Coquette outside Paris.

Lafayette Flying Corps is a name used to describe the American volunteer pilots who flew for the French during World War I.  It includes the pilots who flew with the bona fide Lafayette Escadrille squadron. The estimations of number of pilots range from 180 to over 300.  The generally accepted number of pilots who successfully completed French flight training is 209.  Of these, 180 served in combat. 

Hugh Terres was one of a few who shared their combat experience with inexperienced US Army pilots.
