For 15 months after, he acted as Resident Medical Officer at Lambeth Infirmary and attended Guy's Hospital weekly as Chief Clinical Assistant in the Throat Department. He passed the examination of F.R.C.S. in 1914 but was only admitted to Fellowship because he was 24 years old at the time he qualified. In April 1915, after passing the Final Fellowship he took a temporary commission at the rank of Lieutenant in the R.A.M.C. For a short time he was attached to the Cambridge Hospital in Aldershot. He entered the war in France on 25th May 1915 and acted temporarily as a Regimental Medical Officer.

Welch Regiment from the 27th to cover the M.O. on leave. George reported himself to the regiment but was advised he was not needed so rejoined the Field Ambulance. From 10th to 21st November 1916 he finally took temporary medical charge of the 2nd Bn. Welch Regiment, rejoining the Field Ambulance on the 21st. He was granted leave from 30th March to 13th April 1916 on renewal of his contract.
