 The Byzantine state and its fleet were thus in no state to resist the naval might of Venice, which supported the Fourth Crusade. When Alexios III and Stryphnos were alerted to the fact that the Crusade was sailing for Constantinople, only 20 "wretched and decayed" vessels could be found, according to Niketas Choniates. During the first Crusader siege of the city in 1203, the attempts of the Byzantine ships to oppose the Crusader fleet from entering the Golden Horn were repulsed, and the Byzantine attempt to employ fireships failed due to the Venetians' skill at handling their ships.
