‘My escape was truly miraculous, for I was very dangerously wounded — A wound half the size of this sheet of paper through my groin and out the side — My hip bone gone etc. etc. — By no means trifling. I most certainly have good reasons to be thankful — I get splendid parcels from our Red Cross and such a great amount of clothing as well. A few days ago I received a complete uniform — boots — shoes — four sets of under-clothing & toilet requisites etc.’

I wonder that I’m not dotty. Doctors say that no one else could have lived through what I had.’
