Eddie Rickenbacker,
Fighting the Flying Circus — Chapter 31
(1919)
“ To know that human beings were lying there without a possible means of escape — waiting there while the pitiless hailstorm of shrapnel drew slowly closer to their hiding places — seemed such a diabolical method of torture that I wondered why men in the trenches did not go utterly mad with terror. Suddenly I noticed that our gunners had drawn back their range to the exact line of the trenches. A first shell fell directly into the trench in front of me, tearing it open and gutting it completely for a space of thirty feet. ”
