It was yesterday evening, just as night fell, that it happened. The day had been fairly calm . . . and nothing forewarned us of a German attack. Suddenly one of my comrades shouted, “Hallo! what is this coming down on us? Any one would think it was petroleum [fuel].” At that time we could not believe the truth, but the liquid which began to spray on us was certainly some kind of petroleum. The Germans were pumping it from hoses . . . A few seconds later incendiary [fire- starting] bombs began to rain down on us and the whole trench burst into flame . . . the men began to scream terribly, tearing off their clothes, trying to beat out the flames . . . We had our eyebrows and eyelashes burned off, and clothes were burned in great patches and our flesh was sizzling like roasting meat.
