In September, 1884, having driven the rebels out of Berber, Gordon authorized his companions, Colonel Stewart and Frank Power (_Times_ correspondent), to go down the river in the steamer Abbas to open communication with Dongola. The steamer struck on a rock, and they were both treacherously murdered. Gordon was now the only Englishman in Khartoum. On December 20th, Lord Wolseley launched Sir Herbert Stewart's expedition from Korti across the desert to Metemmeh, where, after two severe engagements, it arrived on January 20, 1885, under command of Sir Charles Wilson, Stewart having been mortally wounded. In order to succor the advancing force, Gordon had deprived himself for three months of five out of his seven steamers. These five steamers, fully armed, equipped, and provisioned, were in waiting, and in them were his diaries and letters up to December 14th. On that date he wrote to Major Watson, R.E., at Cairo, that he thought the game was up, and a catastrophe might be expected in ten days' time, and sent his adieux to all. On the same day he wrote to his sister: "I am quite happy, thank God, and like Lawrence, I have tried to do my duty." His diary ended on the same day with: "I have done the best for the honor of my country. Good-by." It was necessary for the safety of his troops that Wilson should first make a reconnoissance down the river toward Berber before going to Khartoum, and when he started up the river, on January 24th, the difficulties of navigation were so great that it was midday on the 28th before the goal was reached, and then only to find it in the hands of the Mahdi, Khartoum having fallen early on the 26th, after a siege of 317 days. From the most accurate information since obtained, it appears that the garrison, early in January, had been reduced to great straits for want of food, and great numbers of the inhabitants had availed themselves of Gordon's permission to join the Mahdi. Omdurman, opposite to Khartoum, on the west bank of the river, fell about January 13th, and about the 18th a sortie was made, in which some serious fighting took place. The state of the garrison then grew desperate. Gordon continually visited the posts by night as well as day, and encouraged the famished garrison. The news of Sir Herbert Stewart's expedition, and the successful engagements it had fought on the way to Metemmeh, determined the Mahdi to storm Khartoum before reinforcements could arrive for its relief. The attack was made on the south front at 3.30 a.m., on Monday, January 26, 1885. The defence was half-hearted, treachery was at work, and Gordon received no tidings of the assault. The rebels made good their entrance, and then a general massacre ensued. The accounts of Gordon's death are confused and conflicting, but they all agree in stating that he was killed near the gate of the palace, and his head carried to the Mahdi's camp.
