At three o'clock in the morning the army was, as usual, under arms. Half an hour later there was a sudden outburst of firing on the extreme left. The firing continued, but it did not increase in strength, as would have been the case had a serious attack been made, and General Moore, who was the general officer of the night, remained on the right, against which portion of the line he believed the real attack would be delivered. It was still dark, and all waited anxiously for some sign of the spot against which the storm was to burst.
