When war broke out in August 1914, they were serving as part of 4th London Brigade, 2nd London Division. The Division had just arrived for their annual summer camp on Salisbury Plain; they were at once recalled to their home base and mobilized for war service. George first went overseas in March 1915. He served in France until October 1918. See also the letters written by George to his family.
