49 Pryor notes that, given the Venetians’ knowledge of the weakness of the Byzantine navy, if Constantinople was always the planned target for the crusade, then the provision of 50 war galleys was superfluous. By contrast, the Egyptian navy was known to be more of a danger, hence the provision of war galleys to fight them. This is further proof that the crusade intended to go to Egypt from its inception.
