[426] Now Placidus's concern was to exclude them in their flight from getting into the village; and causing his horse to march continually on that side of them, he then turned short upon them, and at the same time his men made use of their darts, and easily took their aim at those that were the nearest to them, as they made those that were further off turn back by the terror they were in, till at last the most courageous of them brake through those horsemen and fled to the wall of the village. And now those that guarded the wall were in great doubt what to do; for they could not bear the thoughts of excluding those that came from Gadara, because of their own people that were among them; and yet, if they should admit them, they expected to perish with them, which came to pass accordingly; for as they were crowding together at the wall, the Roman horsemen were just ready to fall in with them. However, the guards prevented them, and shut the gates, when Placidus made an assault upon them, and fighting courageously till it was dark, he got possession of the wall, and of the people that were in the city, when the useless multitude were destroyed; but those that were more potent ran away, and the soldiers plundered the houses, and set the village on fire. As for those that ran out of the village, they stirred up such as were in the country, and exaggerating their own calamities, and telling them that the whole army of the Romans were upon them, they put them into great fear on every side; so they got in great numbers together, and fled to Jericho, for they knew no other place that could afford them any hope of escaping, it being a city that had a strong wall, and a great multitude of inhabitants. But Placidus, relying much upon his horsemen, and his former good success, followed them, and slew all that he overtook, as far as Jordan; and when he had driven the whole multitude to the river-side, where they were stopped by the current, (for it had been augmented lately by rains, and was not fordable,) he put his soldiers in array over against them; so the necessity the others were in provoked them to hazard a battle, because there was no place whither they could flee. They then extended themselves a very great way along the banks of the river, and sustained the darts that were thrown at them, as well as the attacks of the horsemen, who beat many of them, and pushed them into the current. At which fight, hand to hand, fifteen thousand of them were slain, while the number of those that were unwillingly forced to leap into Jordan was prodigious. There were besides two thousand and two hundred taken prisoners. A mighty prey was taken also, consisting of asses, and sheep, and camels, and oxen.
