That afternoon the "Dal" and two of the gunboats left Fashoda and steamed away up the Nile towards Sobat. Before leaving, the Sirdar sent a formal written document to Major Marchand, protesting against any usurpation by another Power of the rights of Great Britain and Egypt to the Nile Valley. He stated that he would refuse to recognise in any way French authority in the country. There was found to be large quantities of grass weed and sudd in the Nile at no great distance from Fashoda. In several places the clear channels were less than 150 yards wide. As the steamers made southing, the river became narrower and the obstacles to navigation more serious--floating islands of weeds and banked sudd blocking the fairway, leaving it but 50 yards or less in width. It is about 62 miles from Fashoda to the Sobat river, that Abyssinian tributary to the Nile. There was formerly an Egyptian station and fort on the neck of land at the junction of the two rivers. Other stations were also held by Khedivial troops further up the river in the old days before the Mahdi's rebellion. It was on the 20th September, the date as officially given, that the flotilla reached Sobat. The place was overgrown with bush, as compared with what had formerly been the case. Only a few natives were seen upon the mainland and islands, and they were friendly disposed. The Sobat, though but 150 yards or so wide, is 30 feet deep when in flood. Its yellow stream runs at two knots an hour, the current driving far into the wider and slacker waters of the Nile, which is about three-quarters of a mile wide at that point. The banks were accessible, and a landing of the troops was much more easily effected than had been the case at Fashoda. As soon as the soldiers and the two remaining guns of Captain Peake's battery were got ashore, the Egyptian flag was formally hoisted and greeted. It was the Sirdar who directed the whole proceedings. The ceremonial observance attending the re-occupation was precisely similar to that which had taken place at Fashoda. Major Smith Dorian was placed in command of the post and district. Three companies of the 13th Soudanese were left as a garrison together with the two Maxim-Nordenfeldt guns. A gunboat was also detailed to proceed a little way up the Sobat and the Bahr el Ghazal.
