Gordon Digs In
Though London desired to abandon Sudan, Gordon firmly believed the Mahdists needed to be defeated or they could overrun Egypt. Citing a lack of boats and transport, he ignored his orders to evacuate and began organizing a defense of Khartoum. In an effort to win over the city's residents, he improved the justice system and remitted taxes. Recognizing that Khartoum's economy rested on the slave trade, he re-legalized slavery despite the fact that he had originally abolished it during his earlier term as governor-general.
While unpopular at home, this move increased Gordon's support in the city. As he moved forward, he began requesting reinforcements to defend the city. An initial request for a regiment of Turkish troops was denied as was a later call for a force of Indian Muslims. Increasingly agitated by Gladstone's lack of support, Gordon began sending a series of angry telegrams to London.
These soon became public and led to a vote of no confidence against Gladstone's government. Though he survived, Gladstone steadfastly refused to become committed to a war in Sudan. Left on his own, Gordon began enhancing Khartoum's defenses. Protected to the north and west by the White and Blue Niles, he saw that fortifications and trenches were constructed to the south and east.
Facing the desert, these were supported by land mines and wire barriers. To defend the rivers, Gordon retrofitted several steamers into gunboats which were protected by metal plates. Attempting an offensive near Halfaya on March 16, Gordon's troops faltered and took 200 casualties. In the wake of the setback, he concluded that he should remain on the defensive.
The Siege Begins
Later that month, Mahdist forces began to near Khartoum and skirmishing commenced. With Mahdist forces closing in, Gordon telegraphed London on April 19 that he had provisions for five months. He also requested two to three thousand Turkish troops as his men were increasingly unreliable. Gordon believed that with such a force, he could drive off the enemy.
As the month ended, the tribes to the north elected to join with the Mahdi and cut off Gordon's lines of communication to Egypt. While runners were able to make the journey, the Nile and telegraph were severed. As enemy forces surrounded the city, Gordon attempted to convince the Mahdi to make peace but with no success.
Trapped in Khartoum
Holding the city, Gordon was able to somewhat replenish his supplies by raiding with his gunboats. In London, his plight was played up in the press and eventually, Queen Victoria directed Gladstone to send aid to the beleaguered garrison. Acquiescing in July 1884, Gladstone ordered General Sir Garnet Wolseley to form an expedition for the relief of Khartoum.
Despite this, it took a substantial amount of time to organize the needed men and supplies. As the fall progressed, Gordon's position became increasingly tenuous as supplies dwindled and many of his more capable officers were killed. Shortening his line, he constructed a new wall inside the city and tower from which to observe the enemy. Though communications remained spotty, Gordon did receive word that a relief expedition was en route.
Despite this news, Gordon greatly feared for the city. A letter that arrived in Cairo on December 14 informed a friend, "Farewell. You will never hear from me again. I fear that there will be treachery in the garrison, and all will be over by Christmas." Two days later, Gordon was forced to destroy his outpost across the White Nile at Omdurman. Made aware of Gordon's concerns, Wolseley began pressing south.
Defeating the Mahdists at Abu Klea on January 17, 1885, the men met the enemy again two days later. With the relief force approaching, the Mahdi began planning to storm Khartoum. Possessing around 50,000 men, he ordered one column to wade across the White Nile to attack the city's walls while another assaulted the Massalamieh Gate.
The City Falls
Moving forward on the night of January 25-26, both columns quickly overwhelmed the exhausted defenders. Swarming through the city, the Mahdists massacred the garrison and around 4,000 of Khartoum's residents. Though the Mahdi had expressly ordered that Gordon be taken alive, he was struck down in the fighting. Accounts of his death vary with some reports stating he was killed at the governor's palace, while others claim he was shot in the street while trying to escape to the Austrian consulate. In either case, Gordon's body was decapitated and taken to the Mahdi on a pike.
Aftermath
In the fighting at Khartoum, Gordon's entire 7,000-man garrison was killed. Mahdist casualties are not known. Driving south, Wolseley's relief force reached Khartoum two days after the city's fall. With no reason to remain, he ordered his men to return to Egypt, leaving Sudan to the Mahdi.
It remained under Mahdist control until 1898 when Major General Herbert Kitchener defeated them at the Battle of Omdurman. Though a search was made for Gordon's remains after Khartoum was retaken, they were never found. Acclaimed by the public, Gordon's death was blamed on Gladstone who delayed forming a relief expedition. The resulting outcry led his government to fall in March 1885 and he was formally rebuked by Queen Victoria."
