With Emin
Jephson was sent on ahead to the lake with the Advance, took the boat up to Mswa, and met Emin on 27 April 1888. Emin brought his steamer to the south end of the lake, and there met Stanley on the 29th, who was surprised to find the figure of Emin to have "not a trace on it of ill-health or anxiety", and celebrated with three bottles of champagne that had been carried all the way up the Congo. Emin provided Stanley with food and other supplies, thus rescuing the rescuers.
At this point things became difficult. Emin was primarily interested in ammunition and other supplies, and a communications route, all of which would assist him in remaining in Equatoria, while Stanley's main goal was to bring Emin out. A month of discussion produced no agreement, and on 24 May Stanley went back to Fort Bodo, arriving there 8 June and meeting Stairs, who had returned from Ugarrowwa's with just fourteen surviving men. On the way Stanley saw the Ruwenzori Mountains for the first time (although Parke and Jephson had seen them on 20 April).
