THE DERVISH INVASION OF EGYPT. 425 the Khalifa's chief lieutenant. It is worth noting that, in as far as I can discover, the Khalifa himself never took part in the raids which he directed against Egypt. After the battle of Toski, in August, 1889, no further serious attempt was made to invade Egypt, while on the other hand, no attempt was made by the Egyptian Government, under British control, to move the frontier of Egypt further southwards. For nearly seven years there was a sort of armed truce, if I may use the word, between Egypt and the Soudanese Government installed at Khartoum under Abdullah el Taashi.
