[485] As Titus was saying this, an extraordinary fury fell upon the men; and as Trajan was already come before the fight began, with four hundred horsemen, they were uneasy at it, because the reputation of the victory would be diminished by being common to so many. Vespasian had also sent both Antonius and Silo, with two thousand archers, and had given it them in charge to seize upon the mountain that was over against the city, and repel those that were upon the wall; which archers did as they were commanded, and prevented those that attempted to assist them that way; And now Titus made his own horse march first against the enemy, as did the others with a great noise after him, and extended themselves upon the plain as wide as the enemy which confronted them; by which means they appeared much more numerous than they really were. Now the Jews, although they were surprised at their onset, and at their good order, made resistance against their attacks for a little while; but when they were pricked with their long poles, and overborne by the violent noise of the horsemen, they came to be trampled under their feet; many also of them were slain on every side, which made them disperse themselves, and run to the city, as fast as every one of them were able. So Titus pressed upon the hindmost, and slew them; and of the rest, some he fell upon as they stood on heaps, and some he prevented, and met them in the mouth, and run them through; many also he leaped upon as they fell one upon another, and trod them down, and cut off all the retreat they had to the wall, and turned them back into the plain, till at last they forced a passage by their multitude, and got away, and ran into the city.
