In May of 1480 the Turkish galleys under the command of Sultan Mohamet (Mehmet) laid siege to the island of Rhodes, home of the Order of St. John. Forty thousand Turks strove to conquer it. The siege lasted three months and finally the Ottoman army was defeated, despite their numerical superiority, by the embattled Order of St. John. Tradition has it that in the last battle the victory was not inclined towards any of the two sides that fought bravely. The heavens opened and the figures of the Blessed Virgin Mary and St. John the Baptist (Patron of the Order) caused such terror to the infidel that the Christian troops put them to flight and managed to achieve the desired victory.

The Frenchman William of Cauorsin (c.1430-1501) Vice Chancellor of the Order of St. John was one of the knights who fought in the siege of Rhodes. As witness testified to the facts in his Obsidionis Rhodiae Urbis Descriptio
