Meanwhile the howitzer battery had again opened fire at daybreak, and continued its work of destruction amongst the buildings of Omdurman. The effect of the Lyddite shells was so terrible that the Khalifa seems to have abandoned his plan of falling back behind the walls of his capital. This was a most fortunate thing, so far as we were concerned, for if, after the fearful slaughter of his troops in the first half of the engagement, the Khalifa had retreated with ten or fifteen thousand men inside the tortuous streets and crowded houses of Omdurman, we should have had the utmost difficulty in driving the enemy out, and could not, in all probability, have occupied Omdurman on the evening of the 2nd. House-to-house fighting is always a costly and dangerous business, and had it taken place, the prophetic estimate popularly attributed to the Sirdar of "one thousand casualties before Khartum is ours," might well have been realised in fact. As it was, the Dervishes prepared to take their chance in the open desert, rather than await our onset under a continual fire of fifty-pounder shells which burst amid sheets of flame and clouds of dust, and sent huge fragments for hundreds of yards, wrecking every obstacle in their path. When the battle was over, the gunboats steamed up side by side with the general advance, and were met at Omdurman by a hot rifle fire from Dervishes concealed in the houses along the margin of the river. The streets leading to the southern exit of the town were by this time crowded with a mass of fugitives. In addition to mounted Baggaras and Dervish infantry, a mob of inhabitants--men, women, and children, dragging after them camels, horses, and donkeys laden with goods and chattels--all this confused stream of human beings and animals was pressing madly forward in panic-stricken flight. Orders were given to fire upon the fugitives, and as the artillerymen on the gunboats, from their raised position, could see well over the walls, a deadly fire was opened upon the crowded thoroughfares. One street especially, which led down to the river, was swept by a frightful hail of Maxim bullets, which mowed the poor wretches down in scores. After taking part in the battle and the subsequent destruction of fugitives, the gunboats proceeded, on the night of the 2nd, about one hundred miles farther up the river, and returned to Omdurman on 5th September with the report that they had seen no more Dervishes.
