The following letter has been received from the Officer Commanding:- "Dear Captain Cragg, – I am very sorry to inform you that your son went into action with us on July 1st and was killed. His Company was the leading one of his Battalion to go over, and all his officers were hit. He was very keen, and I much regret his loss. Lieut. Cragg was wounded in the leg in the Battle of Loos, on September 25th, 1915, but he made a good recovery, and afterwards came home on leave. In January, he was blown out of a trench, and suffered from shell shock. Captain and Mrs. Cragg had four officer sons in the Army, and this is the second to fall, the other being Lieut. Noel Henry Cragg, killed in action at Nieuport on September 15th, 1915.
