At first the English were very surprised by our disregarding the Hague Convention. But from 1916 onward they used at least as much poison as we did.
First we attacked the Russian soldiers with our gases, and then when we saw the poor fellows lying there, dying slowly, we tried to make breathing easier for them by using our own life-saving devices on them.
I felt profoundly ashamed, I was very much upset.
I knew that the Hague Convention prohibited the use of poison in war. I didn’t know the details of the terms of the Convention, but I did know of that prohibition.
