Kosheh is six miles south of Firket, and consists, like most places in the 'Military Soudan,' of little more than a name and a few ruined mud-huts which were once a village. On the 5th of July the whole camp was moved thither from the scene of the action. The reasons were clear and apparent. Kosheh is a point on the river above the Dal Cataract whence a clear waterway runs at high Nile to beyond Dongola. The camp at Firket had become foul and insanitary. The bodies of the dead, swelling and decaying in their shallow graves, assailed, as if in revenge, the bodies of the living. The dysentery which had broken out was probably due to the 'green' water of the Nile; for during the early period of the flood what is known as 'the false rise' washes the filth and sewage off the foreshore all along the river, and brings down the green and rotting vegetation from the spongy swamps of Equatoria. The water is then dangerous and impure. There was nothing else for the army to drink; but it was undesirable to aggravate the evil by keeping the troops in a dirty camp. The earliest freight which the railway carried to Kosheh was the first of the new stern-wheel gunboats. Train after train arrived with its load of steel and iron, or with the cumbrous sections of the hull, and a warship in pieces--engines, armaments, fittings and stores--soon lay stacked by the side of the river. An improvised dockyard, equipped with powerful twenty-ton shears and other appliances, was established, and the work--complicated as a Chinese puzzle--of fitting and riveting together the hundreds of various parts proceeded swiftly. Gradually the strange heaps of parts began to evolve a mighty engine of war. The new gunboats were in every way remarkable. The old vessels had been 90 feet long. These were 140 feet. Their breadth was 24 feet. They steamed twelve miles an hour. They had a command of 30 feet. Their decks were all protected by steel plates, and prepared by loopholed shields for musketry. Their armament was formidable. Each carried one twelve-pounder quick-firing gun forward, two six-pounder quick-firing guns in the central battery, and four Maxim guns. Every modern improvement--such as ammunition hoists, telegraphs, search-lights, and steam-winches--was added. Yet with all this they drew only thirty-nine inches of water. The contract specified that these vessels should be delivered at Alexandria by the 5th of September, but, by exertions, the first boat, the Zafir, reached Egypt on the 23rd of July, having been made in eight weeks, and in time to have assisted in the advance on Dongola. The vessels and machinery had been constructed and erected in the works in London; they were then marked, numbered, and taken to pieces, and after being shipped to Alexandria and transported to the front were finally put together at Kosheh. Although in a journey of 4,000 miles they were seven times transhipped, not a single important piece was lost.
