But they remained, and as misfortunes rarely come alone, their own subjects just at this juncture rose in arms against them, and in their extremity they sought for peace at Mahomet's hands, offering to become his tributaries; and the conqueror sent over one of his generals and an army and quieted the insurrection. As vassals to the Turk the two princes lived for a few years (but not in the greatest harmony with each other), and then hearing that "the Christian princes of the west were making great preparation against the Turke," refused further tribute to Mahomet, who thereupon re-entered Peloponnesus, with a "puissant army," and the Greek princes had to fly for their lives, the one to Mantinia, and the other to "the strong cittie of Epidaurus, now called Ragusa." Again they had to sue for peace, which Mahomet, after stripping them of almost all the little authority they had left, and imposing further tribute, granted. Not long after this Mahomet was himself disquieted by rumours of the Christian princes of the west being about to intervene and drive him out of Greece, and thinking probably there would be no settled peace for him in the Peloponnesus, while the Greek princes remained there with any semblance of power, and the brothers Paleologi being at variance between themselves, and the promised tribute also not forthcoming, availed himself of the opportunity to finally subdue it. He therefore marched into those parts with a large force, reducing the cities, laying waste the country, and cruelly putting to death thousands of its inhabitants. Demetrius fled to Sparta, but when Mahomet arrived there, he came out and "humbly submitted himself with all he had in his power," which so "pleased the Turkish tyrant, that hee courteously received him, and comforted him; neverthelesse, hee committed him to safe custodie, and carried him about with him as his prisoner." Thence after much ravage and slaughter the Moslem victor, "by the counsell of Demetrius, 'sent one of his captaines, with certaine companies of Greeke souldiours, unto the strong cittie of Epidaurus, to command them in the name of the prince, to deliver unto him the citie, with the prince, his wife, and daughter, that lay there. But the Governour trusting unto the strength of the citie, refused to deliver the same; yet suffred the princess with her daughter, to depart out of the citie, being willing to goe to her husband; whom the captaine having received, returned and presented them to _Mahomet_; by whose commandment they were sent into Beotia, there to attend his returne toward Constantinople, and an eunuch appointed to take charge of the young ladie who had so warmed _Mahomet's_ affection, that he tooke her afterwards to his wife.'"
