The army of the insurgents, for which there was no retreat, was completely extirpated.

The prisoners taken in the battle--between 3000 and 4000 in number, including the generals Damasippus, Carrinas, and the severely-wounded Pontius-- were by Sulla's orders on the third day after the battle brought to the Villa Publica in the Campus Martius and there massacred to the last man, so that the clatter of arms and the groans of the dying were distinctly heard in the neighbouring temple of Bellona, where Sulla was just holding a meeting of the senate.

It was a ghastly execution, and it ought not to be excused; but it is not right to forget that those very men who perished there had fallen like a band of robbers on the capital and the burgesses, and, had they found time, would have destroyed them as far as fire and sword can destroy a city and its citizens.
Sieges Praeneste Norba Nola With this battle the war was, in the main, at an end.

The garrison of Praeneste surrendered, when it learned the issue of the battle of Rome from the heads of Carrinas and other officers thrown over the walls.

The leaders, the consul Gaius Marius and the son of Pontius, after having failed in an attempt to escape, fell on each other's swords.
