Sickness broke out among the half-starved Turks, and, after a stay of only thirteen days in the island, they re-embarked. But in that short time they had wrought enormous damage. They had ravaged the fair island with fire and sword, and they carried away more than 20,000 captives[257]. The population was so greatly reduced by this wholesale deportation that nearly forty years afterwards the whole island contained only some 17,500 inhabitants, and rather more than a century after this siege a census showed that the total was not more than 50,000—a much smaller number than in classical days, when it is estimated to have been 100,000. In 1761 it had declined to 44,333; at the end of the Venetian occupation it was put down at 48,000; a century later, in 1896, it was 90,872[258]. At the census of 1907 it was 94,451. Butrinto and Paxo, less able to defend themselves than Corfù, fell into the hands of the Turks, who plundered several of the other Ionian islands. Great was the joy of Venice at the news that the invaders had abandoned Corfù, and public thanksgivings were offered up for the preservation of the island, even in the desolate condition in which the Turks had left it. A Corfiote, named Noukios, secretary of an Ambassador of Charles V and author of three books of travels, the second of which, relating to England, has been translated into English, wrote, with tears in his eyes, a graphic account of this terrible visitation. One result of this invasion was the tardy but systematic fortification of the town of Corfù, at the repeated request of the Corfiote council, which sent several embassies to Venice with that object. More than 2000 houses were pulled down in the suburb of San Rocco to make room for the walls, for which the old classical city, Palaiopolis, as it is still called, provided materials, and Venice spent a large sum on the erection of new bastions. Two plans are in existence showing the fortifications of the citadel and of the town about this period[259], and some parts of the present Fortezza Vecchia date from the years which followed this first Turkish siege. The still existing Fortezza Nuova was built between 1577 and 1588, when the new works were completed. Another result of the Turco-Venetian war was the grant of lands at Corfù to the Greek soldiers, or _stradioti_, who had formed the Venetian garrisons of Monemvasia and Nauplia, and for whom provision had to be made when, in 1540, the Republic ceded these two last of her Peloponnesian possessions to the sultan. The present suburb of Stratia still preserves the name of these soldiers. The loss of the Venetian stations in the Morea and the subsequent capture of Cyprus by the Turks naturally increased the numbers of the Greeks in Corfù.
