The expedition's next destination was Sarawak, on the island of Borneo. By the time they left Sarawak, the conflict between Beebe and Horsfall had grown to such a degree that Beebe decided Horsfall was endangering the expedition and must be sent home. In response to Beebe's dismissal, Horsfall retorted that he had been ill-treated by Beebe from the beginning of the expedition and that his subsequent actions had been for the express purpose of revenge. Continuing without Horsfall, Beebe and Blair traveled to Batavia in Java, to the island of Madura just to the north, and to Belitung between Borneo and Sumatra.
