three o'clock in the morning
Orders were at once issued for a number of the troops to set to work to complete the defences . Another battery was , during the night , erected in front of the Roman ruins . A redoubt in front of the position of the Guards was strengthened , and other points seen to . 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 .
