|The quantity of men wounded and injured in this war was on a scale never seen before or since.|
The RAMC went out into "no man's land" unarmed during and after each action, to tend to the wounded and dying; and bring them back. That is what this corporal did. In modern terms he would be called a paramedic.
The overseas service chevrons on his right cuff indicate he was in his third year abroad. Many were themselves wounded . This man was, as the wound stripe on his left cuff shows.
Inscribed on the front : Yours Irving 6-4-18
Estimate: There can't be many RAMC Corporals with the Military Medal called Irving
