Legend has it that then the island was rescued by the only surviving knight, barely 18 years old. He dressed women and children in the armor of the dead defenders, convincing the Ottomans that the garrison of Leros was still strong. Finally, on 24 December 1522, following the siege of Rhodes, a treaty was signed between Sultan Suleiman and the Grand Master of the Knights, Philippe Villiers de L'Isle-Adam, and Leros, along with all the Aegean possessions of the Order, passed into Ottoman hands which ruled the island with brief interruptions during a period of four hundred years.
