By the 5th October, when Lord Wolseley arrived at Wady Halfa, Sir Herbert Stewart had been for several days at Dongola with 250 Mounted Infantry, who were transported in _nuggars_ (native boats) from Sarras. The whale-boats were arriving daily at Wady Halfa, the first boat having been hauled through the rapids on 25th September, and by the 5th October there were 103 whalers assembled at Wady Halfa. At Wady Halfa is the Second Cataract, at the lower end of which is the gorge of Bab-el-Kebir, the Great Gate. Between Wady Halfa and Dal are the cataracts of Samneh, Attireh, Ambigol, Tangour and Akasha. At intervals of about 33 miles from Sarras to (New) Dongola, stations were established with commissariat depots. The transport of troops and stores from the base camp at Wady Halfa to Dongola consisted of the steamers, whale-boats, and _nuggars_ along the river, the train from Wady Halfa to Sarras, from Sarras to Ambigol by camel, thence by water. The Camel Corps marched along the east bank to Dongola. It was composed of four regiments, Heavy, Light, Guards, and Mounted Infantry, each being composed of detachments from cavalry and infantry regiments, each detachment consisting of two officers, two sergeants, two corporals, one bugler, and 38 men; total, 94 officers, 1700 N.C.O.'s and men. Such, in brief, was the condition of affairs early in October (1884), when I was stationed at the Second Cataract at Wady Halfa. Here the Nile divides into two, flowing on either side of a group of rocks and islands for about 20 miles, and at the other (or upper) end of the group of rocks and islands, on the east (or left) bank, is the sickle-shaped gorge of Bab-el-Kebir. At this time, although the {228} river was falling, the roar of the torrent pouring through the Bab was so tremendous, that no voice could be heard, and we communicated with one another by semaphore. When I left the Bab, goats were feeding in the bed of the river. Lord Wolseley told me that he was informed that it was impossible to haul the steamers up the Second Cataract, and asked me if I could do it. I replied that nothing was impossible until it was proved to be impossible; and that, in the case under consideration, I would admit the impossibility when I had smashed two steamers in trying to get them through; while if I smashed only one, I might thereby get experience which would enable me to succeed with the other. The steamers were hauled through successfully while the Bab-el-Kebir was still full and roaring, the current being so powerful that the steamers forging against it trembled like a whip.
