The strong ramparts of Canea opposed but an ineffectual resistance to the numbers and resolution of the Ottomans, who pressed the siege with all the ardour arising from the confidence of success; and after fifty days of open trenches, and the failure of two assaults, the second fortress of the island capitulated, August 17. The churches and the cathedral of St Nicholas were converted into mosques: and Delhi-Hussein (whose subsequent tragical fate has been already commemorated) was sent out to take the government of this new conquest. The brave Yusuf, returning to Constantinople at the end of the year, was at first received with the highest honours by Ibrahim, but soon after put to death in one of his fits of senseless cruelty; but the Ottomans in Crete, under the gallant leadership of Delhi-Hussein, who now became _serdar_ or commander-in-chief, overran and occupied the inland districts almost without opposition from the Greek inhabitants, in whose eyes any alternative was preferable to the bloody tyranny under which they had so long groaned:[15] while the Venitian garrisons, shut up in the fortified towns along the northern shore, depended for supplies on the Christian fleet, which the Turks did not venture to bring to action. The campaign of 1646 was marked by the capture of the important city of Retimo, which surrendered Nov. 15, after a murderous siege of thirty-nine days, in which both the governor Cornaro and the provveditor Molino were slain: but though the Turks received reinforcements to the amount of 30,000 men, including 10,000 janissaries, in the course of the following year, it was not till May 1648 that the trenches were at length opened before Candia, the capital of the island, and the only fortress of importance still in the hands of the Venetians. [15] Many of them adopted the faith of the invaders--and Tournefort, who visited Crete in 1700, says that "the greater part of the Turks on the island were either renegades, or sons of renegades." The Candiote Turks of the present day are popularly held to combine the vices of the nation from which they descend with those of their adopted countrymen.
