He joined the RAMC in 1913 as a surgeon-lieutenant, attached to 10 Bn King's (Liverpool) Regt. aka the Liverpool Scottish.
He received his MC as a Lieutenant, then his two VCs as a Captain for rescuing the wounded from no-man's land, first in the Ypres salient then on the Somme, then back to Ypres in 1917 for the attacks on Passchendale.
He was killed when a shell came through the door of the dug-out he was using as an aid post.
