Even when the railway had reached Dakhesh the tension was only slightly relaxed. The necessity of supplying the large force at Berber, 108 miles from Railhead, still required the maintenance of a huge and complicated system of boat and camel transport. Of course, as the railway advanced, it absorbed stage after stage of river and portage, and the difficulties decreased. But the reader may gain some idea of their magnitude by following the progress of a box of biscuits from Cairo to Berber in the month of December 1897. The route was as follows: From Cairo to Nagh Hamadi (340 miles) by rail; from Nagh Hamadi to Assuan (205 miles) by boat; from Assuan to Shellal (6 miles) by rail; from Shellal to Halfa (226 miles) by boat; from Halfa to Dakhesh (Railhead)--248 miles--by military railway; from Dakhesh to Shereik (45 miles) by boat; from Shereik by camel (13 miles) round a cataract to Bashtinab; from Bashtinab by boat (25 miles) to Omsheyo; from Omsheyo round another impracticable reach (11 miles) by camel to Geneinetti, and thence (22 miles) to Berber by boat. The road taken by this box of biscuits was followed by every ton of supplies required by 10,000 men in the field. The uninterrupted working of the long and varied chain was vital to the welfare of the army and the success of the war. It could only be maintained if every section was adequately supplied and none were either choked or starved. This problem had to be solved correctly every day by the transport officers, in spite of uncertain winds that retarded the boats, of camels that grew sick or died, and of engines that repeatedly broke down. In the face of every difficulty a regular supply was maintained. The construction of the railway was not delayed, nor the food of the troops reduced.
