Abdallahi ibn Muhammad
Several years later, having rebuilt an Egyptian army (including British and many Sudanese troops) and constructed railways and fleets of Nile steamboats to secure the lines of communication across the desert, the British again advanced into the Sudan under General Kitchener. The forces of the Khalifa Abdallahi ibn Muhammad, successor to the Mahdi, were bloodily defeated at the Battle of Omdurman and Britain established control over the Sudan. The last potential Anglo-French colonial dispute was resolved shortly afterwards in the Fashoda Incident, when a French expedition withdrew from southern Sudan and France acknowledged Britain's possession. This was one of the incidents resulting in an end to the long-standing colonial rivalries between Britain and France.
