From an interview with John Fallwain, a former military man from Cork, Ireland:

"war is a terrible experience. I had to kill by any means to survive. I killed a man with the butt of my own revolver. My conscience still torments me for such a ruthless murder of a man, though armed, but a man.

During the war, I missed my family ith John so much that I wrote family and heart with dirt, because I didn't have enough love either.

Over time, I felt that I was starting to go crazy. It seemed to me that the war was forever. In an attempt to get rid of the back thoughts, I drew with the help of dirt and rust on my revolver. And I even liked it."
