four o'clock
At one o'clock the word to advance was passed round quietly . The moon was full and high overhead , so there was no difficulty in avoiding obstacles . Each brigade marched in square , accompanied by the guns and the Maxims , and the camels with provisions and spare ammunition . At four o'clock they halted again . They had been well guided , and were now but a short distance from the enemy 's position . At sunrise the men were again on their feet , and advanced to within two hundred yards of the position from which they were to deliver their attack . The British brigade -- the Camerons , Warwicks , Seaforths , and Lincolns -- were on the left .
