The island on which the town stands is joined to the mainland by a causeway, at the further end of which is an arched gateway of curious design called 'the Gate of the Soudan.' Upon the mainland stands the crescent-shaped suburb of El Kaff. It comprises a few mean coral-built houses, a large area covered with mud huts inhabited by Arabs and fishermen, and all the barracks and military buildings. The whole is surrounded by a strong wall a mile and a half long, fifteen feet high, six feet thick, with a parapet pierced for musketry and strengthened at intervals by bastions armed with Krupp guns. Three strong detached posts complete the defences of Suakin. Ten miles to the northward, on the scene of Sir H. Kitchener's unfortunate enterprise, is the fort of Handub. Tambuk is twenty-five miles inland and among the hills. Situate upon a high rock, and consisting only of a store, a formidable blockhouse, and a lookout tower, this place is safe from any enemy unprovided with artillery. Both Handub and Tambuk were at the outset of the campaign provisioned for four months. The third post, Tokar Fort, lies fifty miles along the coast to the south. Its function is to deprive the Arabs of a base in the fertile delta of the Tokar river. The fort is strong, defended by artillery, and requires for its garrison an entire battalion of infantry. No description of Suakin would be complete without some allusion to the man to whom it owes its fame. Osman Digna had been for many years a most successful and enterprising Arab slave dealer. The attempted suppression of his trade by the Egyptian Government drove him naturally into opposition. He joined in the revolt of the Mahdi, and by his influence roused the whole of the Hadendoa and other powerful tribes of the Red Sea shore. The rest is upon record. Year after year, at a horrid sacrifice of men and money, the Imperial Government and the old slaver fought like wolves over the dry bone of Suakin. Baker's Teb, El Teb, Tamai, Tofrek, Hashin, Handub, Gemaiza, Afafit--such were the fights of Osman Digna, and through all he passed unscathed. Often defeated, but never crushed, the wily Arab might justly boast to have run further and fought more than any Emir in the Dervish armies.
