On 12 August 1345 Venetians started to
besiege the city and the surrounding
castles. Their land army was commanded by
Marco Giustiniani and their
marine forces were under the command of Pietro de Canale. The siege consisted of many separate operations, movements,
battles and other military activities, that can be divided into three
phases. The first phase ended at the end of January 1346 with the Venetians' breaking of the
harbour chain which from the beginning of siege prevented Venetian
galleys from entering the Zadar port. The breaking enabled the besiegers to come closer to the
city walls and to control the movements of Zadar ships. In the meantime, Pietro Civrano took over supreme command of the Venetian forces as
capitaneus generalis. The second phase was marked by the king Louis' army entering the conflict. In
late springtime the King's forces attacked the Venetian fortress (
bastida) built near Zadar at the beginning of the siege, but without success. Although large in number (according some sources up to 100,000 men), they were compressed in the narrow passage between the fortress and the sea, so they could not come closer strong enough to capture the fortress. Besides, they were under heavy fire from two sides – from the Venetian ships and from
ballistic devices in the fortress. The major attack of the Croato-Hungarian forces took place on 1 July 1346, but at the end the Venetians carried the day. Louis the Angevin decided to retreat and ordered his troops to move northwards. In the third phase Zadar's defenders remained alone. They were short of food and water and without new
supply lines, but they fought on until December. Finally, on 21 December 1346 the Venetian troops marched into town and took control of it. == Aftermath ==
