in the midst of the tension the blaze of lights in his head went out, and he fell into a half-conscious doze. When he started into full consciousness again the men were stirring, and he became aware that the sergeant was calling for volunteers.
Volunteers for what? He didn't know and was afraid to ask. But it became clear to him that the one chance to wash his guilt away (was that funny old-fashioned phrase a quotation, and where did it come from?) was to offer himself for the job, whatever it might be.
The decision once taken, he became instantly calm, happy and alert. He observed the gesture made by the other volunteers and imitated it. It was too dark for the sergeant to distinguish one man from another, and without comment he let Troy fall into the line of men who were creeping up out of the hollow.
