Sudanese troops refused evacuation and revolted for Egypt. [fact]
In November, Stack was murdered in Cairo. In angry response, Lord Allenby, then British consul in Egypt, quickly ordered the evacuation of all Egyptian troops from the Sudan. Zaghlül refused to issue the order, and Egyptian troops stationed in the Sudan refused to evacuate. In a gesture of loyalty to Egypt, Sudanese troops in the Eleventh Battalion rebelled and tried to reach their Egyptian colleagues to the north of Khartoum. Under heavy British fire, the Sudanese troops were finally defeated after retreating to a military hospital. The troops were dis- appointed that no similar gesture of loyalty had come from the Egyptian soldiers, who did not fire against the British. Then, the evacuation of Egyptian soldiers was accomplished quickly and completely, and by the end of November, the revolution in the Sudan had died down.
