It was not until the 11th March, however, that Gessi received a sufficient supply of ammunition to enable him to assume the offensive. Suleiman's camp or fort was a strongly barricaded enclosure, surrounded by a double row of trunks of trees. The centre of the enclosure was occupied by an inner fort, which was Suleiman's own residence. On Gessi attacking it, his first shell set fire to one of the huts, and as the wood was dry, the whole encampment was soon in a blaze. Driven to desperation, the brigands sallied forth, only to be driven back by the steady fire of Gessi's troops, who by this time were full of confidence in their leader. Then the former broke into flight, escaping wherever they could. Suleiman was among those who escaped, although eleven of his chiefs were slain, and the unfortunate exhaustion of Gessi's powder again provided him with the respite to rally his followers and make another bid for power. This further period of enforced inaction terminated at the end of April, when the arrival of a full supply of powder and cartridges enabled Gessi to take the field for the last time. On the 1st May the Egyptian commander started to attack the slave robber in his last stronghold, Dem Suleiman. Three days later he fought the first of these final battles outside that fort, and succeeded in cutting off the retreat of the vanquished Arabs into that place of shelter. He then broke into the fort itself, where there were only a few men, and he almost succeeded in capturing Suleiman, who fled through one gate as Gessi entered by another. Thanks to the fleetness of his horse, Suleiman succeeded in making good his escape. Before his hurried flight Suleiman murdered four prisoners sooner than allow of their recapture, and throughout the long pursuit that now began all slaves or black troops who could not keep up were killed. These were not the only crimes perpetrated by these brigands. Superstition, or the mere pleasure of cruelty, had induced them when their fortunes were getting low to consecrate a new banner by bathing it in the blood of a murdered child. For these iniquities the hour of expiation had now arrived.
