From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
When at the end of forty days the navigation had been everywhere set free in the western basin of the Mediterranean, Pompeius proceeded with sixty of his best vessels to the eastern seas, and first of all to the original and main seat of piracy, the Lycian and Cilician waters. On the news of the approach of the Roman fleet the piratical barks everywhere disappeared from the open sea; and not only so, but even the strong Lycian fortresses of Anticragus and Cragus surrendered without offering serious resistance. The well-calculated moderation of Pompeius helped even more than fear to open the gates of these scarcely accessible marine strongholds. His predecessors had ordered every captured freebooter to be nailed to the cross; without hesitation he gave quarter to all, and treated in particular the common rowers found in the captured piratical vessels with unusual indulgence.
The bold Cilician sea-kings alone ventured on an attempt to maintain at least their own waters by arms against the Romans; after having placed their children and wives and their rich treasures for security in the mountain-fortresses of the Taurus, they awaited the Roman fleet at the western frontier of Cilicia, in the offing of Coracesium. But here the ships of Pompeius, well manned and well provided with all implements of war, achieved a complete victory. Without farther hindrance he landed and began to storm and break up the mountain-castles of the corsairs, while he continued to offer to themselves freedom and life as the price of submission. Soon the great multitude desisted from the continuance of a hopeless war in their strongholds and mountains, and consented to surrender. Forty-nine days after Pompeius had appeared in the eastern seas, Cilicia was subdued and the war at an end.
