From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The rapid suppression of piracy was a great relief, but not a grand achievement; with the resources of the Roman state, which had been called forth in lavish measure, the corsairs could as little cope as the combined gangs of thieves in a great city can cope with a well-organized police. It was a naive proceeding to celebrate such a razzia as a victory. But when compared with the prolonged continuance and the vast and daily increasing extent of the evil, it was natural that the surprisingly rapid subjugation of the dreaded pirates should make a most powerful impression on the public; and the more so, that this was the first trial of rule centralized in a single hand, and the parties were eagerly waiting to see whether that hand would understand the art of ruling better than the collegiate body had done.
Nearly 400 ships and boats, including 90 war vessels properly so called, were either taken by Pompeius or surrendered to him; in all about 1300 piratical vessels are said to have been destroyed; besides which the richly-filled arsenals and magazines of the buccaneers were burnt. Of the pirates about 10,000 perished; upwards of 20,000 fell alive into the hands of the victor; while Publius Clodius the admiral of the Roman army stationed in Cilicia, and a multitude of other individuals carried off by the pirates, some of them long believed at home to be dead, obtained once more their freedom through Pompeius. In the summer of 687, three months after the beginning of the campaign, commerce resumed its wonted course and instead of the former famine abundance prevailed in Italy.
