On October 21 the Mahdi himself arrived in the camp outside Khartum, and on the following day sent Gordon convincing proofs that Stewart's steamboat had sunk and that all on board had been slain. He added a list of all the journals and documents found on board. From these the Mahdi had learned almost to a day how long Khartum could hold out, the strength of the garrison, the scheme of defence, where the batteries stood and how long the ammunition would last. This was a terrible blow to the lonely soldier, but it did not break down his courage. The death of Stewart and his companions grieved him inexpressibly, but he sent an answer to the Mahdi that if 20,000 boats had been taken it would be all the same to him--"I am here like iron." In the relief expedition was a major named Kitchener, who was afterwards to become very famous. He tried to get into Khartum in disguise to carry information to Gordon, and he did succeed in sending him a letter with the news that the relieving force would set out from Dongola on November 1. When the letter reached Gordon the corps had been two days on the march, but the distance from Dongola to Khartum is 280 miles in a straight line. By November 22 Gordon had lost nearly 1900 of his fighting men, but his diary shows that he was still hopeful. On December 10 there were still provisions for fifteen days. The entries in the diary now become shorter, and repeatedly speak of fugitives and deserters, and of the diminishing store of provisions. On December 14 Gordon had a last opportunity of sending news from Khartum, and the diary which the messenger took with him closes with these words: "I have done the best for the honour of our country. Good-bye." After the sending-off of the diary impenetrable darkness hides the occurrences of the last weeks in Khartum. One or two circumstances, however, were made known by deserters. During the forty days during which the town held out after December 14, 15,000 townspeople were sent over to the Mahdi's camp, and only 14,000 civilians and soldiers were left in the doomed city. Omdurman fell, and the Mahdi's troops pressed every day more closely on all sides. Actual starvation began, and rats and mice, hides and leather were eaten, and palms stripped to obtain the soft fibres inside. But the White Pasha rejected all proposals to surrender. Meanwhile the relief columns struggled southwards and on January 20, 1885, reached Metemma, only a hundred miles from Khartum. There they fell in with Gordon's boats, which had lain waiting in vain for four months, and four days later two of the boats started for Khartum.
