Apparently chastened by their failed relief effort and the loss of so valuable a warship, the French abandoned Candia in August 1669 leaving Captain General Francesco Morosini, the commander of Venetian forces, with only 3,600 fit men and scant supplies to defend the fortress. He, therefore, accepted terms and surrendered to Ahmed Köprülü, the Grand Vizier of the Ottoman Empire on 27 September 1669. However, his surrender without first receiving authorization to do so from the Venetian Senate made Morosini a controversial figure in Venice for some years afterward.
