Frantic shouts to the Guards to stand firm were heard. Both officers and men still faced the enemy, although the line of the Heavies was bent into an irregular semicircle extending into the square as far as the kneeling camels behind. These camels formed a useful breastwork, beyond which the assailants could not penetrate, and over and around the animals the battle raged, both parties fighting hand to hand, bayonet against spear. For ten minutes a desperate struggle extended from the left rear to the centre. It was at this period that Colonel Burnaby fell, a spear having severed his jugular vein, but not until he had killed with his own hand more than one of his assailants. Stewart's horse was thrown off his legs and then speared, and his orderly was killed beside him. The General's life was only saved by the coolness and presence of mind of Sir Charles Wilson, who was standing next to him. A few of the enemy had crawled in between the camels, and one man who had succeeded in doing this was making, spear in hand, for the General. Sir Charles Wilson observed the move, whipped out his revolver, and shot the man dead. Many of the camels were speared by the assailants, and the interior of the square formed a mass of falling camels and struggling combatants, half hidden amid dust and smoke. The issue could not, however, be said to have been a moment in doubt, for the Heavy Camel Corps were soon supported by soldiers from the other side of the square. These were in readiness to oppose any further advance had the line given way, though they were obliged to withhold their fire so long as the two parties were mingled in the strife. Later on they faced about and fired into the square, killing no doubt both friends and foes. It was not long before every Arab who had entered the square was killed, the rest beaten back, and amid three hearty cheers the square re-formed on fresh ground away from the killed and wounded. It was now half-past three, and as the enemy moved off the guns opened on them with grape at 500 yards range, and hastened their retreat.[110] They withdrew in a slow, sullen way, turning round from time to time as if anxious to come on again. Eventually the last of them disappeared over the sand-hills. The force opposed to Stewart was stated by the prisoners taken to consist of ten tribes of about 800 men each. According to the report of the Intelligence Department, their numbers were still greater, and were made up of Ababdeh, Bisharin, and other Arabs from Berber, soldiers of the old Egyptian army, Arabs and others from Metammeh, men of the Mahdi's regular army (400 armed with rifles), and Arabs of various tribes from Kordofan.
