Harry was educated at Pelham Street School, Brighton, then became a Compositor in the employment of Messrs. Billing & Sons. He enlisted into the R.A.M.C. on 23rd October 1915. He was 26 years and 5 months old; and was living at 3 Springfield Road, Guildford at the time. On enlistment, he was posted to “T” Co, then on the 28th was transferred to serve with the 134th Field Ambulance. He was first promoted to acting Lance Corporal on 11th December 1915. Harry embarked, with his unit, at Southampton on 6th March 1916, then disembarking at Havre the next day, entered war in France on 7th March 1916. He was appointed acting Corporal on 26th June 1916, however, his rank reverted back and forth on several occasions. He was awarded the Distinguished Conduct Medal "For conspicuous gallantry and devotion to duty as bearer. He remained all night in "No Man's Land" with 17 wounded and was responsible for the recovery of these men, dragging them by means of blankets and waterproof sheets along the ground. He then returned for more, and his work during the whole of the operations was marked by gallantry and devotion of the highest order." He was himself wounded at Jara Drive on 26th September 1917, receiving gun shot wounds to his head and thigh. He died from him wounds at No 41 Casualty Clearing Station. Harry’s Commanding Officer, Lt/Col H C Hilditch wrote: “ I cannot express to you my great loss of such a noble, gallant man, the pride of my unit. Practically the whole unit turned out to pay our last respects, but that was a feeble return for such a splendid example. I need hardly say he was loved and admired by all, and he has been ever since he joined us. We are particularly sorry for you, who would have loved to see him with the D.C.M., which he richly deserved. It will be some comfort to you to know he died a hero’s death.” A comrade also wrote: “No decoration in all the war has been more worthily given. It was a brave and self-sacrificing deed that Harry did when he preformed the action for which he was decorated; he was admired and respected by all.” Harry was the only son of Harry and Elizabeth Naomi (daughter of George and Mary Likeman) Tallon of 17 Port Hall Place, Brighton.
