During the night of October 13th-14th, the British opened an attack with gas on the front south of Ypres. They used the yellow gas whose effect was unknown to us, at least from personal experience. I was destined to experience it that very night. On a hill south of Werwick, in the evening of October 13th, we were subjected for several hours to a heavy bombardment with gas bombs, which continued throughout the night with more or less intensity. About midnight a number of us were put out of action, some for ever. Towards morning I also began to feel pain. It increased with every quarter of an hour; and about seven o'clock my eyes were scorching as I staggered back and delivered the last dispatch I was destined to carry in this war. A few hours later my eyes were like glowing coals and all was darkness around me.
