The campaign in the Adriatic has been credited with having a significant effect on the wider war through the disruption of French forces in the Balkans. It has been suggested that Napoleon intended to invade the Ottoman Empire following the War of the Fifth Coalition, but was dissuaded in part due to the difficulty of supplying a force in the region without control of the Adriatic, his attention eventually turning to Russia. The campaign also had effects on the morale and effectiveness of the French fleet, which lost some of its best commanders and frigates in the campaign, and on the Austrian advance on Italy in 1813, when French defence lines were repeatedly out-flanked by British attacks from the sea.
