"Ay, ay, sir," answered Tommy.  He picked out the first twenty men he could lay hands on and taarched them off to join Mr Marline's "picnic," as he expressed it, and the rest of us went off at the double to take part in the scrimmage that was proceeding in the neighbourhood of the sand pits.  And a very pretty scrimmage it was, if one might judge from the tremendous medley of sounds that reached us from that direction. The firing was now very irregular and intermittent, but there was plenty of yelling and shrieking mingled, as we drew nearer to the scene of the fray, with sounds of gasping as of men engaged in a tremendous struggle, quick ejaculations, a running fire of forecastle imprecations, the occasional sharp order of an officer to "Rally here, lads!" dull, sickening thuds as of heavy blows crashing through yielding bones, and here and there a groan, or a cry for water.  It was evident that the fight had resolved itself into a desperate hand-to-hand struggle; and it seemed to me that our lads were being hard put to it to hold their own. But the worst feature of the whole affair, to my mind, was that the darkness was so intense that it was almost impossible to distinguish friend from foe.
