Go to sleep!  Yes, it was excellent advice, but I did not seem able to follow it just then; the throbbing and aching of my arm and the racking pain of my sore head were altogether against it, to say nothing of the continuous groaning and moaning of the injured men round about me, and the occasional sharp ejaculations of agony extorted from the unfortunate individual who happened at the moment to be under the surgeon's hands. So, instead, I looked about me and endeavoured to form some idea of the extent of our casualties during the past night.  Judging from what I saw, they must have been pretty heavy, for I counted twenty-three wounded, including myself, and I realised that there might be others elsewhere, for the tent in which we lay was full; there did not seem to be room enough for another patient in it without undue crowding.  And even supposing that we comprised the sum total of the wounded, there must have been a large proportion of dead in so desperate an affair as that of the past night.  I estimated that in so obstinately contested a fight as that in which we had all sustained our injuries, and against such tremendous odds as those which were opposed to us, there must have been at least half as many dead as wounded, which would make our casualties up to thirty-five; a very heavy percentage out of a crew that, owing to various causes, was already, before this fresh misfortune, growing short-handed.  When to these came to be added the casualties sustained on the preceding day in the attack upon the barracoon, it seemed to me that our new captain would have little more than a mere handful of men available for service on this fresh expedition upon which he had embarked--for I did not suppose that he had gone off taking with him every sound man and leaving the camp and the wounded entirely unprotected and exposed to a renewed attack by the savages.
