Only three days have elapsed since I last wrote to you, but those three days have completely changed the prospects of things here. Then a move forward appeared to be an event which, we hoped, might happen somewhere in the dim future, but which, with the reports that provisions were scarcely accumulating at Senafe, but were being consumed as fast as they were taken up, seemed a very distant matter indeed. Now all this is changed, and “forward” is the cry. The 25th Native Infantry are already on the move, the 4th, “King’s Own,” are to go in a day or two, and the 3d Native Infantry are to follow as soon as possible. Sir Robert Napier goes up to-morrow or next day. Whether he will remain up there, and go forward at once, or whether he will return here again for a short time, is a moot point. I incline to the former opinion. From what I hear, and from what I see in the English papers, pressure is being strongly applied to Sir Robert Napier to move forward. Now, with the greatest deference for the home authorities and for the leader-writers upon the London press, I submit that they are forming opinions upon matters on which no one who has not visited this place is competent to judge. No one, I repeat, can form any opinion of the difficulties with which the Commander-in-chief has to contend here. The first want is the want of water, the second the want of forage, the third the want of transport. Twenty-eight thousand animals were to have been here by the end of December; not more than half that number have arrived, and of the 12,000 which have been landed 2000 are dead, and another 2000 unfit for work. The remainder are doing quite as much as could be expected of them, and are working well and smoothly; but 8000 are not sufficient to convey the provisions and stores of an army up seventy miles, and to carry their own forage as well. That is, they might convey quite sufficient for their supply from day to day, but they cannot accumulate sufficient provisions for the onward journey. The difficulties are simply overwhelming, and I do not know of a position of greater responsibility than that of Sir Robert Napier at the present moment. If he keeps the troops down here upon the plain, the increasing heat may at any moment produce an epidemic; and, in addition to this, the English public will ferment with indignation. On the other hand, if he pushes on with a few thousand men, he does so at enormous risk. He may take any number of laden animals with them; but if we get, as in all probability we shall get, into a country where for days no forage is obtainable, what is to become of the animals? It is not the enemy we fear—the enemy is contemptible; it is the distance, and the questions of provisions and transport. If a column goes on, it cuts itself loose from its base. With the exception of the laden animals, which start with it, it can receive no supplies whatever from the rear; it must be self-supporting. When Sherman
