He was killed whilst attending to wounded. His Brigadier-General wrote:- “He is a great loss to the Service, and did an enormous amount of good.... When there was any fighting going on he seemed indefatigable; he seemed to be able to go on with sleep indefinitely. The enemy shells had no terrors for him, and if there were any need for his services in the most dangerous places, he always went.” Frank was the eldest son of Dr Auriol Armitage. He was married and had one child.
