I think it was about 9 a.m. when the Sirdar's army, re-formed for marching, stepped clear of the zereba and the trenches. The order of advance for the infantry was as before, in echelon of brigades, the British being on the left and in front. Lyttelton's 2nd brigade was leading, Wauchope's was behind it. On the right were Maxwell's and Lewis's brigades. Macdonald was to look after our extreme right rear flank, whilst Collinson followed in the gap nearer the river. Lyttelton's brigade was directed to pass to the left, east of Jebel Surgham, Maxwell's left was to extend to and pass over the hill, whilst Lewis and Macdonald would sweep part of the valley between Surgham and South Kerreri. Such was the general direction to be taken, exposing a front measured on the bias, of fully one mile. Once more the 21st Lancers trotted out towards Jebel Surgham to make sure there were no large bodies of the enemy in hiding. Keeping somewhat closer to the river than previously, and avoiding the main field of battle, they passed to the east of the hill. Part of their duty was to check, if possible, any attempt of the enemy to fall back into Omdurman, or at least delay such an operation. Great numbers of scattered dervishes were seen, some of whom fired at the troopers. Keeping on until about half a mile or more south of Surgham, a small party of dervish cavalry, about thirty, and what was thought to be a few footmen, were seen hiding in a depression or khor. Colonel Martin determined to push the party back and interpose his regiment between them and Omdurman. A few spattering shots came from the khor, as the four squadrons formed in line to charge. "A" squadron, under Major Finn, was on the right, next it was "B" squadron, commanded by Major Fowle. On the left of "B" was "D," or the made-up squadron, led by Captain Eadon, and "C" squadron, under Captain Doyne, was on the extreme left. [Illustration: A. GENERAL VIEW PLAN.
