The Crusade fleet left Venice during the first week of October 1202, following an emotional and rousing ceremony in San Marco di Venezia where Dandolo "took the cross" –committed himself to crusading–and promised to "go live or die" with the Crusaders in exchange for his people's support, and his sons' taking his place during his absence. The Crusaders arrived in Zara in November, the sheer size of their fleet intimidating the Zarans into near surrender. Dandolo gave the Zarans an ultimatum: either they leave the city right away or they would be killed. Confusion ensued, as Pope Innocent forbade the Crusade from settling this dispute unrelated to their original religious agenda, especially since the land was controlled by King Emeric of Hungary, who had himself participated in a crusade. Finally, Innocent threatened excommunication to anyone who antagonized the Zarans. The Crusaders attacked the city anyway, and it at last fell on 24 November 1202. All of the Venetian members of the Crusade were thus excommunicated (the French Crusaders had sent an envoy to the pope to ask for forgiveness), but Dandolo kept this a secret from them since he knew they would abandon the Crusade if they found out.
