A few days after the return of headquarters to Berber, Mahmud was sent down country, and Fatma was permitted to accompany him. She expressed to Gregory, in touching terms, her gratitude for what he had done for her.  
"We have been of mutual assistance," said Gregory. "I have the same reason to be grateful to you, as you have to thank me. I saved your life, and you saved mine. You were very kind to me, when I was a captive--I have done as much as I could for you, since you have been with us. So we are quits. I hope you will be happy with Mahmud. We do not treat our prisoners badly, and except that he will be away from the Soudan, he will probably be more comfortable than he has ever been in his life."
 
Gregory was now employed in the transport department, and journeyed backwards and forwards, with large convoys of camels, to the head of the railway. The line was completed to Berber, but the officers charged with its construction were indefatigable; and, as fast as the materials came up, it was pushed on towards the Atbara. Complete as had been the victory on that river, the Sirdar saw that the force which had been sufficient to defeat the twenty thousand men, under Mahmud, was not sufficiently strong for the more onerous task of coping with three times that number, fighting under the eye of the Khalifa, and certain to consist of his best and bravest troops. He therefore telegraphed home for another British brigade, and additional artillery, with at least one regiment of cavalry--an arm in which the Egyptian Army was weak.
 
Preparations were at once made for complying with the request. The 21st Lancers, 1st battalion of Grenadier Guards, 2nd battalion of the Rifle Brigade, 2nd battalion of the 5th Lancashire Fusiliers, a field battery, a howitzer battery, and two forty-pounders, to batter the defences of Omdurman, should the Khalifa take his stand, were sent. A strong detachment of the Army Service Corps and the Royal Army Medical Corps was to accompany them, but they had yet some months to wait, for the advance would not be made until the Nile was full, and the gunboats could ascend the cataract.
 
However, there was much to be done, and the troops did not pass the time in idleness. Atbara Fort was to be the base, and here the Egyptian battalions built huts and storehouses. The Soudanese brigades returned to Berber, and the transport of provisions and stores for them was thus saved. The British at Darmali were made as comfortable as possible, and no effort was spared to keep them in good health, during the ensuing hot weather. A small theatre was constructed, and here smoking concerts were held. There was also a race meeting, and one of the steamers took parties, of the men who were most affected by the heat, for a trip down the Nile. They were practised in long marches early in the morning, and although, of course, there was some illness, the troops on the whole bore the heat well.
 
Had there been a prospect of an indefinitely long stay, the result might have been otherwise; but they knew that, in a few months, they would be engaged in even sterner work than the last battle, that Khartoum was their goal, and with its capture the power of the Khalifa would be broken for ever, and Gordon avenged.
 
Early in April the railway reached Abadia, a few miles from Berber, and in a short time a wonderful transformation took place here. From a sandy desert, with scarce a human being in sight, it became the scene of a busy industry. Stores were sorted and piled as they came up by rail.
 
Three gunboats arrived in sections, and these were put together. They were stronger, and much better defended by steel plates than the first gunboats; and each of them carried two six-pounder quick-firing guns, a small howitzer, four Maxims, and a searchlight. They were, however, much slower than the old boats, and could do very little in the way of towing.
 
Besides these, eight steel double-deck troop barges were brought up, in sections, and put together. Three Egyptian battalions came up from Merawi to aid in the work, which not only included building the gunboats and barges, but executing the repairs to all the native craft, and putting them in a thoroughly serviceable state.
 
In June the railway reached the Atbara, and for the first time for two years and a half, the officers who had superintended its construction had a temporary rest. The stores were now transferred from Abadia to the Atbara, and two trains ran every day, each bringing up something like two hundred tons of stores.
 
In the middle of July two Egyptian battalions left Atbara and proceeded up the Nile, one on each bank, cutting down trees and piling them for fuel for the steamers. As the river rose, four steamers came up from Dongola, together with a number of sailing boats; and in the beginning of August the whole flotilla, consisting of ten gunboats, five unarmed steamers, eight troop barges, and three or four hundred sailing boats, were all assembled.
 
By this time the reinforcements from home were all at Cairo, and their stores had already been sent up. It was arranged that they were to come by half battalions, by squadrons, and by batteries, each one day behind the other. To make room for them, two Egyptian battalions were sent up to the foot of the Shabluka cataract.
 
The six black battalions left Berber on July 30th, and arrived at Atbara the next day. There were now four brigades in the infantry divisions instead of three, two battalions having been raised from the Dervishes taken at the battle of Atbara. These were as eager as any to join in the fight against their late comrades.
 
This was scarcely surprising. The Baggara, the tyrants of the desert, are horsemen. The infantry were, for the most part, drawn from the conquered tribes. They had enlisted in the Khalifa's force partly because they had no other means of subsistence, partly from their innate love of fighting. They had, in fact, been little better than slaves; and their condition, as soldiers in the Egyptian Army, was immeasurably superior to that which they had before occupied.
 
Broadwood, with nine squadrons of Egyptian cavalry, was already on the western bank of the river opposite Atbara; and was to be joined at Metemmeh by the camel corps, and another squadron of horse from Merawi.
 
On the 3rd of August the six Soudanese battalions left Fort Atbara for the point of concentration, a few miles below the cataract. To the sides of each gunboat were attached two of the steel barges; behind each were two native craft. All were filled as tightly as they could be crammed with troops. They were packed as in slavers, squatting by the side of each other as closely as sardines in a box. The seven steamers and the craft they took with them contained six thousand men, so crowded that a spectator remarked that planks might have been laid on their heads, and that you could have walked about on them; while another testified that he could not have shoved a walking stick between them anywhere. White men could not have supported it for an hour, but these blacks and Egyptians had a hundred miles to go, and the steamers could not make more than a knot an hour against the rapid stream, now swollen to its fullest.
 
While they were leaving, the first four companies of the Rifle Brigade arrived. Every day boats laden with stores went forward, every day white troops came up. Vast as was the quantity of stores sent off, the piles at Atbara did not seem to diminish. Ninety days' provisions, forage, and necessaries for the whole force had been accumulated there, and as fast as these were taken away they were replaced by others from Berber.
 
Like everyone connected with the transport or store department, Gregory had to work from daybreak till dark. Accustomed to a warm climate, light in figure, without an ounce of spare flesh, he was able to support the heat, dust, and fatigue better than most; and, as he himself said, it was less trying to be at work, even in the blazing sun, than to lie listless and sweating under the shade of a blanket. There was no necessity, now, to go down the line to make enquiries as to the progress of the stores, or of the laden craft on their way up. the telegraph was established, and the Sirdar, at Atbara, knew the exact position of every one of the units between Cairo and himself; and from every station he received messages constantly, and despatched his orders as frequently.
 
There was no hitch, whatever. The arrangements were all so perfect that the vast machine, with its numerous parts, moved with the precision of clockwork. Everything was up to time. For a train or steamer, or even a native boat, to arrive half an hour after the time calculated for it, was almost unheard of.
 
The Sirdar's force of will seemed to communicate itself to every officer under him, and it is safe to say that never before was an expedition so perfectly organized, and so marvellously carried out. At Atbara the Sirdar saw to everything himself. A brief word of commendation, to those working under him, cheered them through long days of toil--an equally curt reproof depressed them to the depths.
 
Twice, when Gregory was directing some of the blacks piling large cases, as they were emptied from the train; anathematizing the stupid, urging on the willing, and himself occasionally lending a hand in order to show how it should be done; the Sirdar, who, unknown to him, had been looking on, rode up and said shortly, "You are doing well, Mr. Hilliard!"--and he felt that his offence of jumping overboard had been condoned.
 
General Hunter, himself indefatigable, had more occasion to notice Gregory's work; and his commendations were frequent, and warm.
 
The lad had not forgotten the object with which he had come to the front. After Atbara, he had questioned many of the prisoners who, from their age, might have fought at El Obeid; but none of these had done so. The forces of the Khalifa came and went, as there was occasion for them. The Baggara were always under arms, but only when danger threatened were the great levies of foot assembled; for it would have been impossible, in the now desolate state of the Soudan, to find food for an army of a hundred thousand men.
 
All agreed, however, that, with the exception of the Egyptian artillerymen, they heard that no single white man had escaped. Numbers of the black soldiers had been made slaves. The whites had perished--all save one had fallen on the field. That one had accompanied a black battalion, who had held together and, repulsing all attacks, had marched away. They had been followed, however, and after repeated attacks had dwindled away, until they had finally been broken and massacred.
 
With the Khalifa's army were several emirs who had fought at El Obeid; and these would, no doubt, be able to tell him more; but none of those who were taken prisoners, at the Atbara, had heard of any white man having escaped the slaughter of Hicks's army.
 
Just as the general movement began, the force was joined by three companies of Soudanese. These had marched from Suakim to Berber, two hundred and eighty-eight miles, in fifteen days, an average of nineteen miles a day--a record for such a march, and one that no European force could have performed. One day, after marching thirty miles, they came to a well and found it dry, and had to march thirty miles farther to another water hole, a feat probably altogether without precedent.
 
"You had better fall back upon your old work, Hilliard," the General said, the day before they started. "As my aide I shall find plenty for you to do, now that I command the whole division."
 
"Thank you very much, sir! I don't think that I shall find any work hard, after what I have been doing for the past four months."
 
"You have got your horse?"
 
"Yes; he is in good condition, for I have had no riding to do, for some time."
 
"Well, you had better get him on board one of the gyasses we shall tow up, tomorrow. All our horses will embark this evening. We shall be on board at daybreak. Our private camels are going with the marching column; you had better put yours with them. No doubt they will join us somewhere. Of course, your kit will be carried with us."
 
It was a delight to Gregory to be on the water again. There was generally a cool breeze on the river, and always an absence of dust. He was now halfway between seventeen and eighteen, but the sun had tanned him to a deep brown, and had parched his face; thus adding some years to his appearance, so that the subalterns of the newly-arrived regiments looked boyish beside him. The responsibilities of his work had steadied him, and though he retained his good spirits, his laugh had lost the old boyish ring. The title of Bimbashi, which had seemed absurd to him seven months before, was now nothing out of the way, for he looked as old as many of the British subalterns serving with that rank in the Egyptian army.
 
Returning to the little hut that Zaki, with the aid of some of the blacks, had built for him; he gave his orders, and in a short time the camel--a very good one, which he had obtained in exchange for that which he had handed over to the transport--started, with its driver, to join those that were to carry up the baggage and stores of General Hunter, and his staff. These were in charge of a sergeant and three privates, of one of the Soudanese battalions. Gregory had got up a case of whisky, one of bottled fruit, and a stock of tea and sugar from Berber. No tents could be carried, and he left his tente d'abri at the stores with his canteen; taking on board, in his own luggage, a plate, knife, fork, and spoon, and a couple of tumblers. When the camels had started, he saw his horse put on board, and then took a final stroll round the encampment.
 
The change that had occurred there, during the past fortnight, was striking. Then none but black faces could be seen. Now it was the encampment of a British force, with its white tents and all their belongings.
 
The contrast between the newly-arrived brigade, and the hardy veterans who had fought at the Atbara, was striking. Bronzed and hearty, inured to heat and fatigue, the latter looked fit to go anywhere and do anything, and there was hardly a sick man in the four regiments. On the other hand, the newcomers looked white and exhausted with the heat. Numbers had already broken down, and the doctors at the hospital had their hands full of fever patients. They had scarcely marched a mile since they landed in Egypt, and were so palpably unfit for hard work that they were, if possible, to proceed the whole way in boats, in order to be in fighting condition when the hour of battle arrived.
 
The voyage up the river was an uneventful one. It seemed all too short to Gregory, who enjoyed immensely the rest, quiet, and comparative coolness. The Sirdar had gone up a week before they landed at Wady Hamed. Here the whole Egyptian portion of the army, with the exception of the brigade that was to arrive the next day, was assembled. The blacks had constructed straw huts; the Egyptians erected shelters, extemporized from their blankets; while the British were to be installed in tents, which had been brought up in sailing boats. The camp was two miles in length and half a mile wide, surrounded by a strong zareba.
 
The Egyptian cavalry and the camel corps had arrived. On the opposite side of the river was a strong body of friendly Arabs, nominally under the Abadar sheik, but in reality commanded by Major Montague Stuart-Wortley. By the 23rd of August the whole force had arrived; and the Sirdar reviewed them, drawn up in battle array, and put them through a few manoeuvres, as if in action. General Gatacre commanded the British division--Colonel Wauchope the first brigade, and Lyttleton the second. As before, Macdonald, Maxwell, and Lewis commanded the first three Egyptian brigades, and Collinson that newly raised, General Hunter being in command of the division.
 
The force numbered, in all, about twenty thousand; and although destitute of the glitter and colour of a British army, under ordinary circumstances, were as fine a body of men as a British general could wish to command; and all, alike, eager to meet the foe. The British division had with them two batteries and ten Maxims, and the Egyptian division five batteries and ten Maxims.
 
As Gregory was strolling through the camp, he passed where the officers of one of the British regiments were seated on boxes, round a rough table, over which a sort of awning had been erected.
 
"Come and join us, Hilliard. We are having our last feast on our last stores, which we got smuggled up in one of the gunboats," the Major called out.
 
"With pleasure, sir."
 
The officer who was sitting at the head of the table made room beside him.
 
"You men of the Egyptian Army fare a good deal better than we do, I think," the Major went on. "That institution of private camels is an excellent one. We did not know that they would be allowed. But, after all, it is not a bad thing that we did not have them, for there is no doubt it is as well that the soldiers should not see us faring better than they. There is bother enough with the baggage, as it is. Of course, it is different in your case. There are only two or three white officers with each battalion, and it would not strike your black troops as a hardship that you should have different food from themselves. They are living as well as, or better than, they ever did in their lives. Three camels make no material addition to your baggage train, while, as there are thirty or forty of us, it would make a serious item in ours, and the General's keen eyes would spot them at once."
 
"Our camels are no burden to the army," Gregory said. "They only have a few pounds of grain a day, and get their living principally on what they can pick up. When they go on now, they will each carry fifty pounds of private grain. They get five pounds when there are no bushes or grass, so that the grain will last them for a fortnight."
 
"I suppose you think that the Dervishes mean fighting?"
 
"I think there is no doubt about it. All the fugitives that come in say that the Khalifa will fight, but whether it will be in the defence of Omdurman, or whether he will come out and attack us at Kerreri, none can say. The Khalifa keeps his intentions to himself."
 
"By the bye, Hilliard, I don't think you know my right-hand neighbour; he only joined us an hour before we started, having been left behind at Cairo, sick.
 
"Mr. Hartley, let me introduce you to Mr. Hilliard--I should say Bimbashi Hilliard. He is on General Hunter's staff."
 
The young lieutenant placed an eyeglass in his eye, and bowed to Gregory.
 
"Have you been in this beastly country long?" he asked.
 
"If you include Lower Egypt, I have been here eighteen years."
 
"Dear me!" the other drawled; "the climate seems to have agreed with you."
 
"Fairly well," Gregory replied. "I don't mind the heat much, and one doesn't feel it, while one is at work."
 
"Hartley has not tried that, yet," one of the others laughed. "Work is not in his line. This most unfortunate illness of his kept him back at Cairo, and he brought such a supply of ice with him, when he came up, that he was able to hand over a hundredweight of it to us when he arrived. I don't think, Major, that in introducing him you should have omitted to mention that, but for a temporary misfortune, he would be the Marquis of Langdale; but in another two years he will blossom out into his full title, and then I suppose we shall lose him."
 
Gregory, whose knowledge of the English peerage was extremely limited, looked puzzled.
 
"May I ask how that is?" he said. "I always thought that the next heir to a title succeeded to it, as soon as his father died."
 
"As a rule that is the case," the Major said, "but the present is an exceptional one. At the death of the late marquis, the heir to the title was missing. I may say that the late marquis only enjoyed the title for two years. The next of kin, a brother of his, had disappeared, and up to the present no news has been obtained of him. Of course he has been advertised for, and so on, but without success. It is known that he married, but as he did so against the wish of his father, he broke off all communication with his family; and it is generally supposed that he emigrated. Pending any news of him, the title is held in abeyance.
 
"He may have died. It is probable that he has done so, for he could hardly have escaped seeing the advertisements that were inserted in every paper. Of course, if he has left children, they inherit the title.
 
"After a lapse of five years Mr. Hartley's father, who was the next heir, and who died five years ago, applied to be declared the inheritor of the title; but the peers, or judges, or someone decided that twenty-one years must elapse before such an application could be even considered. The income has been accumulating ever since, so that at the end of that time, it is probable that Mr. Hartley will be allowed to assume the title.
 
"Will the estates go with the title, Hartley?"
 
"Oh, I should say so, of course!" the other drawled. "The title would not be of much use, without them."
 
"Nonsense, my dear fellow!" another said. "Why, a fellow with y............
