Cheerful in Verse

I was through all the fighting, commencing with the battle of Mons, until the 9th of last month, when I got wounded. This little verse will explain a lot:

I was wounded on the 9th,

Near the River Marne.

They got me in hospital on the 13th,

On the 18th they took off my arm:

A Corporal of the Durham Light Infantry.
