Quite a few soldiers . . . had ended up spending some time wrapped around each other, alone in the night. Most often, it was just for the touch of another person and not in the pursuit of an entangling relationship. In fact, when it happened there was usually an unspoken covenant which existed between soldiers to just forget whatever had happened and move on, as many preferred not to talk about how you secretly needed to curl up in basically the fetal position, tucked away with another psychologically damaged human, deep in the bowels of your tin-can refuge from the deep black, just to get through another week of it all.
