Looks like a touch of Post Traumatic Stress Disorder doesn't it ?His service records prove interesting reading. After his discharge he re-enlisted to what looks like the Argyll & Sutherland Highlanders. There seems to be quite a few times he was absent and forfeiting several days pay. Then he moved onto the Army Service Corps before deserting on 28 July 1917. No more info after that.
However, we must admire his pluck as a 14 year old lad enlisting into a regular battalion of the Worcestershire Regiment and serving for nearly a year in the trenches before being badly wounded with a gun shot wound to his stomach.
