The first, second, and third watches passed uneventfully; but the fourth watch was little more than half through when--about a quarter after three o'clock in the morning--the whole camp was roused from its slumbers by the sound of musket-shots, one from the party guarding the boats and the river approach, quickly followed by three in rapid succession from the contingent that occupied the sand pits stretched across the neck of the peninsula.  Then three or four more shots from the river party spurted out, and it began to dawn upon us that the matter threatened to be serious.  Of course none of us had thought of discarding any of our clothing that night, the second shot therefore had scarcely pealed out upon the night air before we in the camp were upon our feet, with our weapons in our hands, and all drawn up in regular array ready for the next move in the game, with the skipper in command.
