of the Mahdi daily desertions of his Arab and other
soldiers to Gordon took place, and by these and levies among the
townspeople all gaps in the garrison were more than filled up. Such
was the confidence in Gordon that it more than neutralised all the
intrigues of the Mahdi's agents in the besieged town, and scarcely a
man during the first seven months of the siege deserted him; but after
the arrival of the Mahdi there was a complete change in this respect.
In the first place there were no more desertions to Gordon, and then
men began to leave him, partly, no doubt, from fear of the Mahdi, or
awakened fanaticism, but chiefly through the non-arrival of the
British Expedition, which had been so much talked about, yet which
never came. Still to all the enemy's invitations to surrender on the
most honourable terms Gordon gave defiant answers. "I am here like
iron, and I hope to see the newly-arrived English;" and when the
situation had become little short of desperate, at the end of the
year, he still, with bitter agony at his heart, proudly rejected all
overtures, and sent the haughty message: "Can hold Khartoum for twelve
years." Unfortunately the Mahdi knew better. He had read the truth in
all the papers captured on Stewart's steamer, and he knew that
Gordon's resources were nearly spent. Even some of the messages Gordon
sent out by spies for Lord Wolseley's information fell into his hands,
and on one of these Slatin says it was written: "Can hold Khartoum at
the outside till the end of January." Although Gordon may be
considered to have more than held his own against all the power of the
Mahdi down to the capture of Omdurman Fort on 15th January, the Mahdi
knew that his straits must be desperate, and that unless the
expedition arrived he could not hold out much longer. The first
advance of the English troops on 3rd January across the desert towards
the Nile probably warned the enemy that now was the time to renew the
attack with greater vigour, but it does not seem that there is any
justification for the entirely hypothetical view that at any point the
Mahdi could have seized the unhappy town. Omdurman Fort itself fell,
not to the desperate onset of his Ghazis, but from the want of food
and ammunition, and with Gordon's expressed permission to the
commandant to surrender. Unfortunately the details of the most tragic
part of the siege are missing, but Gordon himself well summed up what
he had done up to the end of Octobe
