From the end of March until the close of the siege scarcely a day passed without the exchange of artillery and rifle fire on one side or the other of the beleaguered town. On special occasions the Khedive's garrison would fire as many as forty or even fifty thousand rounds of Remington cartridges, and the Arab fire was sometimes heavier. This incessant fire, as the heroic defender wrote in his journal, murdered sleep, and at last he became so accustomed to it that he could tell by the sound where the firing was taking place. The most distant points of the defence, such as the santal on the White Nile and Fort Omdurman, were two miles from the Palace; and although telegraphic communication existed with them during the greater part of the siege, the oral evidence as to the point of attack was often found the most rapid means of obtaining information. This was still more advantageous after the 12th of November, for on that day communications were cut between Khartoum and Omdurman, and it was found impossible to restore them. The only communications possible after that date were by bugle and flag. At the time of this severance Gordon estimated that the garrison of Omdurman had enough water and biscuit for six weeks, and that there were 250,000 cartridges in the arsenal. Gordon did everything in his power to aid Ferratch in the defence, and his remaining steamer, the Ismailia, after the grounding of the Husseinyeh on the very day Omdurman was cut off, was engaged in almost daily encounters with the Mahdists for that purpose. Owing to Gordon's incessant efforts, and the gallantry of the garrison led by Ferratch, Omdurman held out more than two months. It was not until 15th January that Ferratch, with Gordon's leave, surrendered, and then when the Mahdists occupied the place, General Gordon had the satisfaction of shelling them out of it, and showing that it was untenable.

The severance of Omdurman from Khartoum was the prelude to fiercer fighting than had taken place at any time during the earlier stages of the siege, and although particulars are not obtainable for the last month of the period, there is no doubt that the struggle was incessant, and that the fighting was renewed from day to day. It was then that Gordon missed the ships lying idle at Shendy. If he had had them Omdurman would not have fallen, nor would it have been so easy for the Mahdi to transport the bulk of his force from the left to the right bank of the White Nile, as he did for the final assault on the fatal 26th January.

At the end of October the Mahdi, accompanied by a far more numerous force than Gordon thought he could raise, described by Slatin as countless, pitched his camp a few miles south of Omdurman. On 8th November his arrival was celebrated by a direct attack on the lines south of Khartoum. The rebels in their fear of the hidden mines, which was far greater than it need have been, as it was found they had been buried too deep, resorted to the artifice of driving forward cows, and by throwing rockets among them Gordon had the satisfaction of spreading confusion in their ranks, repulsing the attack, and capturing twenty of the animals. Four days later the rebels made the desperate attack on Omdurman, when, as stated, communications were cut, and the Husseinyeh ran aground. In attempting to carry her off and to check the further progress of the rebels the Ismailia was badly hit, and the incident was one of those only too frequent at all stages of the siege, when Gordon wrote: "Every time I hear the gun fire I have a twitch of the heart of gnawing anxiety for my penny steamers." At the very moment that these fights were in progress he wrote, 10th November: "To-day is the day I expected we should have had some one of the Expedition here;" and he also recorded that we "have enough biscuit for a month or so"—meaning at the outside six weeks. Throughout the whole of November rumours of a coming British Expedition were prevalent, but they were of the vaguest and most contradictory character. On 25th November Gordon learnt that it was still at Ambukol, 185 miles further away from Khartoum than he had expected, and his only comment under this acute disappointment was, "This is lively!"

Up to the arrival 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 October when his position was secure, and aid, as he thought, was close at hand:—

"The news of Hicks's defeat was known in Cairo three weeks after the event occurred; since that date up to this (29th October 1884) nine people have come up as reinforcements—myself, Stewart, Herbin, Hussein, Tongi, Ruckdi, and three servants, and not one penny of money. Of those who came up two, Stewart and Herbin, have gone down, Hussein is dead; so six alone remain, while we must have sent down over 1500 and 700 soldiers, total 2200, including the two Pashas, Coetlogon, etc. The regulars, who were in arrears of pay for three months when I came, are now only owed half a month, while the Bashi-Bazouks are owed only a quarter month, and we have some £500 in the Treasury. It is quite a miracle. We have lost two battles, suffering severe losses in these actions of men and arms, and may have said to have scrambled through, for I cannot say we can lay claim to any great success during the whole time. I believe we have more ammunition (Remington) and more soldiers now than when I came up. We have £40,000 in Treasury in paper and £500. When I came up there was £5000 in Treasury. We have £15,000 out in the town in paper money."

At the point (14th December) when the authentic history of the protracted siege and gallant defence of Khartoum stops, a pause may be made to turn back and describe what the Government and country which sent General Gordon on his most perilous mission, and made use of his extraordinary devotion to the call of duty to extricate themselves from a responsibility they had not the courage to face, had been doing not merely to support their envoy, but to vindicate their own honour. The several messages which General Gordon had succeeded in getting through had shown how necessary some reinforcement and support were at the very commencement of the siege. The lapse of time, rendered the more expressive by the long period of silence that fell over what was taking place in the besieged town, showed, beyond need of demonstration, the gravity of the case and the desperate nature of the situation. But a very little of the knowledge at the command of the Government from a number of competent sources would have enabled it to foresee what was certain to happen, and to have provided some remedy for the peril long before the following despairing message from Gordon showed that the hour when any aid would be useful had almost expired. This was the passage, dated 13th December, in the last (sixth) volume of the Journal, but the substance of which reached Lord Wolseley by one of Gordon's messengers at Korti on 31st December:—

"We are going to send down the Bordeen the day after to-morrow, and with her I shall send this Journal. If some effort is not made before ten days' time the town will fall. It is inexplicable this delay. If the Expeditionary forces have reached the river and met my steamers, one hundred men are all that we require just to show themselves.... Even if the town falls under the nose of the Expeditionary forces it will not in my opinion justify the abandonment of Senaar and Kassala, or of the Equatorial Province by H.M.'s Government. All that is absolutely necessary is for fifty of the Expeditionary force to get on board a steamer and come up to Halfiyeh, and thus let their presence be felt. This is not asking much, but it must happen at once, or it will (as usual) be too late."

The motives which induced Mr Gladstone's Government to send General Gordon to the Soudan in January 1884 were, as has been clearly shown, the selfish desire to appease public opinion, and to shirk in the easiest possible manner a great responsibility. They had no policy at all, but they had one supreme wish, viz. to cut off the Soudan from Egypt; and if the Mahdi had only known their wishes and pressed on, and treated the Khartoum force as he had treated that under Hicks, there would have been no garrisons to rescue, and that British Government would have done nothing. It recked nothing of the grave dangers that would have accrued from the complete triumph of the Mahdi, or of the outbreak that must have followed in Lower Egypt if his tide of success had not been checked as it was single-handed by General Gordon, through the twelve months' defence of Khartoum. Still it could not quite stoop to the dishonour of abandoning these garrisons, and of making itself an accomplice to the Mahdi's butcheries, nor could it altogether turn a deaf ear to the representations and remonstrances of even such a puppet prince as the Khedive Tewfik. England was then far more mistress of the situation at Cairo than she is now, but a helpless refusal to discharge her duty might have provoked Europe into action at the Porte that would have proved inconvenient and damaging to her position and reputation. Therefore the Government fell back on General Gordon, and the hope was even indulged that, under his exceptional reputation, the evacuation of the Soudan might not only be successfully carried out, but that his success might induce the public and the world to accept that abnegation of policy as the acme of wisdom. In all this they were destined to a complete awakening, and the only matter of surprise is that they should have sent so well-known a character as General Gordon, whose independence and contempt for official etiquette and restraint were no secrets at the Foreign and War Offices, on a mission in which they required him not only to be as indifferent to the national honour as they were, but also to be tied and restrained by the shifts and requirements of an embarrassed executive.

At a very early stage of the mission the Government obtained evidence that Gordon's views on the subject were widely different from theirs. They had evidently persuaded themselves that their policy was Gordon's policy; and before he was in Khartoum a week he not merely points out that the evacuation policy is not his but theirs, and that although he thinks its execution is still possible, the true policy is, "if Egypt is to be quiet, that the Mahdi must be smashed up." The hopes that had been based on Gordon's supposed complaisance in the post of representative on the Nile of the Government policy were thus dispelled, and it became evident that Gordon, instead of being a tool, was resolved to be master, so far as the mode of carrying out the evacuation policy with full regard for the dictates of honour was to be decided. Nor was this all, or the worst of the revelations made to the Government in the first few weeks after his arrival at Khartoum. While expressing his willingness and intention to discharge the chief part of his task, viz. the withdrawal of the garrisons, which was all the Government cared about, he also descanted on the moral duty and the inevitable necessity of setting up a provisional government that should avert anarchy and impose some barrier to the Mahdi's progress. All this was trying to those who only wished to be rid of the whole matter, but Gordon did not spare their feelings, and phrase by phrase he revealed what his own policy would be and what his inner wishes, however repressed his charge might keep them, really were.

Having told them that "the Mahdi must be smashed up," he went on to say that "we cannot hurry over this affair" (the future of the Soudan) "if we do we shall incur disaster," and again that, although "it is a miserable country it is joined to Egypt, and it would be difficult to divorce the two." Within a very few weeks, therefore, the Government learnt that its own agent was the most forcible and damaging critic of the policy of evacuation, and that the worries of the Soudan question for an administration not resolute enough to solve the difficulty in a thorough manner were increased and not diminished by Gordon's mission. At that point the proposition was made and supported by several members of the Cabinet that Gordon should be recalled. There is no doubt that this step would have been taken but for the fear that it would aggravate the difficulties of the English expedition sent to Souakim under the command of General Gerald Graham to retrieve the defeat of Baker Pasha. Failing the adoption of that extreme measure, which would at least have been straightforward and honest, and ignoring what candour seemed to demand if a decision had been come to to render Gordon no support, and to bid him shift for himself, the Government resorted to the third and least justifiable course of all, viz. of showing indifference to the legitimate requests of their emissary, and of putting off definite action until the very last moment.
