[522] But now, when the vessels were gotten ready, Vespasian put upon ship-board as many of his forces as he thought sufficient to be too hard for those that were upon the lake, and set sail after them. Now these which were driven into the lake could neither fly to the land, where all was in their enemies' hand, and in war against them; nor could they fight upon the level by sea, for their ships were small and fitted only for piracy; they were too weak to fight with Vespasian's vessels, and the mariners that were in them were so few, that they were afraid to come near the Romans, who attacked them in great numbers. However, as they sailed round about the vessels, and sometimes as they came near them, they threw stones at the Romans when they were a good way off, or came closer and fought them; yet did they receive the greatest harm themselves in both cases. As for the stones they threw at the Romans, they only made a sound one after another, for they threw them against such as were in their armor, while the Roman darts could reach the Jews themselves; and when they ventured to come near the Romans, they became sufferers themselves before they could do any harm to the ether, and were drowned, they and their ships together. As for those that endeavored to come to an actual fight, the Romans ran many of them through with their long poles. Sometimes the Romans leaped into their ships, with swords in their hands, and slew them; but when some of them met the vessels, the Romans caught them by the middle, and destroyed at once their ships and themselves who were taken in them. And for such as were drowning in the sea, if they lifted their heads up above the water, they were either killed by darts, or caught by the vessels; but if, in the desperate case they were in, they attempted to swim to their enemies, the Romans cut off either their heads or their hands; and indeed they were destroyed after various manners every where, till the rest being put to flight, were forced to get upon the land, while the vessels encompassed them about [on the sea]: but as many of these were repulsed when they were getting ashore, they were killed by the darts upon the lake; and the Romans leaped out of their vessels, and destroyed a great many more upon the land: one might then see the lake all bloody, and full of dead bodies, for not one of them escaped. And a terrible stink, and a very sad sight there was on the following days over that country; for as for the shores, they were full of shipwrecks, and of dead bodies all swelled; and as the dead bodies were inflamed by the sun, and putrefied, they corrupted the air, insomuch that the misery was not only the object of commiseration to the Jews, but to those that hated them, and had been the authors of that misery. This was the upshot of the sea-fight. The number of the slain, including those that were killed in the city before, was six thousand and five hundred.
