There was another day's truce on Christmas Day, but at night rumours of a sortie which Baden-Powell intended to make on Game Tree Fort began to spread amongst the officers. At dawn next morning, December 26th, the sortie was made. Two squadrons of the Protectorate Regiment and one squadron of the Bechuanaland Rifles, accompanied by three guns and an armoured train, advanced upon Game Tree Fort in the twilight and began an attack, which Baden-Powell in his despatch to Cape Town characterizes as being "carried out and pressed home with the greatest gallantry and steadiness under very hot fire." The action began by an artillery duel, in which the British Maxim joined as the daylight increased, and was soon general in the vicinity of the fort, which was situated about a mile and a half from the town. At sunrise the attacking force, under Captains Vernon and FitzClarence, was ready to rush the Boer position. Those watching the fight from a little distance saw the men of the Protectorate and Bechuanaland squadrons moving rapidly upon the fort, and heard a continuous rattle of musketry as they drew to close quarters with the enemy. For a while there was some anxiety amongst the watching staff; then it was seen that the British troops were slowly drawing back, "the fort," said Baden-Powell in his despatch, "being practically impregnable." Then came the news of the repulse and the opinion of the commanding officer that the position was too difficult to attempt a second time. But it was not until the list of casualties was made out that anyone not actually engaged in it knew how gallant and strenuous the attack had been. Out of the attacking force of about one hundred men, only one half came back scatheless. Captains Vernon and Sandford, Lieutenant Paton, and twenty-one rank and file were killed; Captain FitzClarence and twenty-two rank and file were wounded; three troopers were taken prisoners. Most of the casualties occurred in the final attempt to storm the fort, and Captain Vernon, in particular, showed magnificent courage. Wounded more than once during the attack, he kept on fighting until he was shot dead. Little wonder that the Boers were greatly impressed by the courage of the besiegers, and that General Snyman began to feel still more doubtful as to the success of his forces!
