As the rainstorms continued, it was decided, by a council of war, that the health of the troops would suffer by a longer stay. On the 29th, therefore, the army set out in order of battle, ready to encounter the Khalifa's attack, but arrived without molestation at Um Teref, a short distance from Kerreri, where it was expected the enemy would give battle.
The camp was smaller than those hitherto made, and was protected by a strong zareba. The sentries were doubled, and patrols thrown out. Heavy rain set in after sunset, and almost a deluge poured down. The tents had been left behind, and as the little blanket shelters were soon soaked through, their occupants were speedily wet to the skin.
It was still raining when, at half-past five, the force again started. As before, the army was marching in fighting order. The day was cool and cloudy, and at one o'clock they halted at a village called Merreh, or Seg. The cavalry had come into touch with the Dervish patrols, but the latter, although numerous, avoided combat.
In one of the deserted villages was found one of Wingate's spies, in Dervish attire. He had left Omdurman thirty hours before, and brought the news that the Khalifa intended to attack at Kerreri. This place had been chosen because there was current an old prophecy, by a Persian sheik, to the effect that English soldiers would one day fight at Kerreri, and be destroyed there. It had, therefore, become an almost holy place to the Mahdists, and was called the death place of all the infidels; and, once a year, the Khalifa and his followers made a pilgrimage to it.
A few shots were fired during the night, and fires blazed on the hills to notify, to Omdurman, our precise position. The troops started again soon after daylight, facing now to the right and marching westward, to leave the bush and broken ground, and get out in the open desert, stretching away to Omdurman. The cavalry were widely spread out, and the Lancers ascended to the top of the hill of El Teb, from which a view of the Dervish camp was obtained.
It lay some ten miles due south. The Dervishes were disposed in three long lines, stretching from within two thousand yards of the Nile out into the desert, being careful to get, as they believed, beyond the range of the four gunboats that steamed quietly up.
After a short march the force halted near the river, two miles north of Kerreri. The place was convenient for camping, but the banks of the river were steep, and there was much difficulty in watering the horses and transport animals.
"We are in for another bad night," one of the General's staff said to Gregory, as the evening approached.
"It looks like it. Clouds are banking up fast. If the rain would but come in the daytime, instead of at night, one would not object to it much. It would lay the dust and cool the air. Besides, on the march we have other things to think of; and though, of course, we should be drenched to the skin, we should not mind it. But it is very unpleasant lying in a pool of water, with streams running in at one's neck."
"As to one's blanket, it is like a sponge, five minutes after the rain begins," the officer said.
