four o’clock
For two hours casualties poured in and every one had a different kind of wound . There was scarcely any part of the human body with which McMahon was not called upon to deal . And the Colonel never once repeated himself . Before four o'clock about a third of the battalion and half of the officers were lying , very well content , in the shade under McMahon 's care . Many of them were sound asleep . The orderly was a man with a sense of military propriety . He insisted on the casualties lying in straight rows , as neatly aligned as if they were on their feet at parade in the barrack square .
