pay for their transport, and to provide military support if they would help him depose his uncle and ascend to his father's throne. The crusaders, whose objective had been Egypt, were persuaded to set their course for Constantinople, arriving there in June 1203, proclaiming Alexios IV as emperor, and inviting the populace of the capital to depose his uncle. Alexios III took no effective measures to resist, and his attempts to bribe the crusaders failed. His son-in-law, Theodore I Laskaris, who was the only one to attempt anything significant, was defeated at Scutari, and the siege of Constantinople began. Misgovernment by Alexios III had left the Byzantine navy with only 20 worm-eaten hulks by the time the crusaders arrived. In July, the crusaders, led by the aged Doge Enrico Dandolo, scaled the walls and took control of a major section of the city. In the ensuing fighting, the crusaders set the city on fire, ultimately leaving 20,000 people homeless. On 17 July, Alexios III finally took action and led 17 divisions from the Gate of St. Romanus, vastly outnumbering the crusaders. His courage failed, however, and the Byzantine army returned to the city without a fight. His courtiers demanded action, and Alexios III promised to fight. Instead, that night (17/18 July), Alexios III hid in the palace, and finally, with one of his daughters, Eirene, and as much treasure (1,000 pounds of gold) as he could collect, got into a boat and escaped to Develtos in Thrace, leaving his wife and his other daughters behind. Isaac II, drawn from his prison and robed once more in the imperial purple, received his son, Alexios IV, in state. Life in exile Alexios III attempted to organize resistance to the new regime from Adrianople and then Mosynopolis, where he was joined by the later usurper Alexios V Doukas in April 1204, after the definitive fall of Constantinople to the crusaders and the establishment of the Latin Empire. At first, Alexios III received Alexios V well, even allowing him to marry his daughter Eudokia Angelina. Later, Alexios V was blinded and deserted by his father-in-law, who fled from the crusaders into Thessaly. Here Alexios III eventually surrendered, with Euphrosyne, to Marquis Boniface of Montferrat, who was establishing himself as ruler of the Kingdom of Thessalonica. Alexios III attempted to escape Boniface's "protection" in 1205, seeking shelter with Michael I Komnenos Doukas, the ruler of
