Shortly after six a.m. on the morning of 22nd July, a large number of officers assembled at the Abbassieh ranges to watch the result of the experiments of the sham bombardment. Lieutenant-General Sir Francis Grenfell and staff, Major-General Lyttelton, and many others were present. It was arranged that the new 5-inch howitzer battery, with the "Lyddite" or high explosive shells, was to make the first attempt to breach or throw down the wall. There were six of these new howitzers, and they were worked by the 37th Field Battery, commanded by Major Elmslie. Except that the bore was larger, there was little to distinguish the pieces from the 15-lb. Maxim-Nordenfeldt automatic recoil guns used at the battle of the Atbara. The latter cannon, however, only used cordite, whereas the 5-inch howitzer shells are filled with a picric compound resembling M. Turpin's melinite. For over ten years Russia has had 100-lb. howitzer batteries in the field, firing high explosives. It was the Sirdar who insisted upon the necessity of being supplied with these light and handy cannon. Neither the velocity nor the range of their shell-fire is great, but it is enough—4000 yards or thereby—for all practical purposes, and is fairly accurate. The explosion of the picric shells was very violent, and the danger area about 300 yards from where they burst. It has been found that, with about six or eight mules to draw the guns, the battery was quite mobile. Egyptian drivers were employed, though the men serving the guns were all British artillerymen. Even the drivers of the 32nd Field Battery, commanded by Major Williams, had "gippy" teamsters. Both batteries were drawn by smart Cyprus mules. The howitzers opened fire at 750 yards from the wall. With few exceptions, the Lyddite shells hit the mark. Range is given more by increase or diminution of the charge than elevation or depression of the howitzers. The guns kicked viciously and ran back at each discharge. Bursting violently, the shells threw out big sheets of tawny flame, followed by showers of stones and a cloud of dust and brownish smoke. It was possible to see the missiles in their flight and note where they struck. As each shell rushed through the air it made a noise not unlike an express train passing under a bridge. There were salvoes of two or three guns, and huge chunks were knocked out of the wall. Pieces of flying débris frequently dropped at no great distance from the gunners. It was plain that the shells were bursting upon impact, and only blowing away the face of the wall to the depth of but a foot or two. Had there been thick shells with retarding fuses the structure might have been breached in two or three rounds.
After a preliminary ten rounds had been fired, the wall was closely inspected. It was seen that infantry might have clambered over the débris to the top of the structure and jumped down upon the other side. A strange feature was that wherever the "Lyddite" explosive failed to detonate the stones and ground around had been transformed to a deep chrome colour. The battery was moved closer, to about 350 yards from the wall, and the firing was recommenced at that range. Much better results were obtained, and the upper part of the wall was knocked away, and easy, practicable breaches made. One of the other advantages of these new guns is that with reduced firing charges they become reliable mortars, and the high explosive shells can be dropped over a wall or building, so as to drive the defenders from their works. Not a man would have escaped injury had there been an enemy behind the wall, for blocks of stone were scattered in all directions. When the howitzers had finished their practice, six rounds were fired from two 40-lb. Armstrong guns, which were also ordered to assist in breaching Omdurman's walls. Next to the 7-lb. screw guns the 40-lb. Armstrong is reputed to be the most accurate shooting cannon in the British service. Mounted on lofty carriages, these siege guns were laid to fire at 800 yards range. Oddly enough, one of the 40-lbs. scored as high a percentage of misses as the howitzers. The great velocity of the 40-lb. shells, filled with the slower-bursting gunpowder, carried them well into the part of the wall aimed at, with the result that, in a few seconds, they made a good breach. The morning's experiments were concluded by a detachment of the Royal Irish Fusiliers, under Captain Churches, firing their Maxims against targets representing bands of dervishes, the dummy enemy being, as usual, riddled with bullets.
From Cairo to Dakhala, evidence was not lacking that the form and movement of preparations for the general advance were growing apace. Every train and boat going south was overloaded with officers, men, and transport animals, together with munitions of war galore for the campaign. The gunboats and deserters brought in reports that the dervishes were concentrating at Omdurman. The strongly defensible positions of Shabluka, together with the mud forts, had been evacuated by the dervishes. Very quickly the Sirdar sent small bodies of troops up stream to occupy suitable positions for wood-cutting and forming advance camps. In that way the river pass at the Sixth Cataract was seized without the long anticipated fight for that difficult bit of country. The Nile highway was at length in the Sirdar's undisputed possession up to within thirty miles of Omdurman.
There is no dustier journey by rail, or one of an altogether more uncomfortable nature, than from Cairo to Shellal. It is bad enough in the so-called winter season, for you have to breathe an atmosphere of dust the whole way, and are powdered and almost suffocated before you reach Luxor. The same trip taken in midsummer, in the stuffy, crowded carriages of the Egyptian lines, is real martyrdom, or something akin thereto. High speed or over twenty-five miles an hour is not attempted. Although the journey ordinarily occupies thirty-two hours, I was forty hours en route. There are no refreshment-bars or restaurants for the supply of palatable food or drink for the fierce needs of the passengers. I made some provision for the trip, and managed to survive it, as I have done before, but I cannot forget its tortures any more than the newest of new-comers. Not until we reached Assouan could we secure a fair supply of water and get a bath and an enjoyable meal. That same afternoon, I, with three other correspondents, was allowed to take passage on barge No. 9, which, with two giassas, was taken in tow up to Wady Halfa by a sternwheeler. Among others proceeding on the craft to join the army were Major-General Wauchope and Surgeon-General Taylor, and a number of other army medicoes, fresh in their new dignity as officers of the "Royal Army Medical Corps." Under the instruction of Surgeon-General Taylor, Surgeon-Major Wilson was good enough to present each of us with a packet of first field dressings, a kindness which I appreciated, but of which I hoped not to have need.
