The Russo-Ottoman siege of Corfu ends with the surrender of the French garrison.

The Russo-Ottoman siege of Corfu in 1799 was a pivotal episode in the struggle for control of the Ionian Islands during the broader conflicts of the French Revolutionary Wars. After the fall of the Venetian Republic in 1797, the Ionian Islands, including Corfu, were ceded to France under the Treaty of Campo Formio. The French quickly fortified the island, recognizing its strategic importance at the entrance to the Adriatic Sea. However, their presence alarmed both the Russian Empire and the Ottoman Empire, who formed an unlikely alliance aimed at curbing French expansion in the eastern Mediterranean. A joint fleet under the command of Russian Admiral Fyodor Ushakov, supported by Ottoman naval forces, began operations in late 1798 to dislodge the French from the region.

The siege itself intensified in early 1799, as Russo-Ottoman forces systematically captured the smaller Ionian islands before concentrating on Corfu, the strongest French-held position. Corfu’s defenses were formidable, centered on its Old and New Fortresses, and protected by the small but heavily fortified island of Vido at the entrance to the harbor. Ushakov implemented a coordinated naval bombardment and land assault strategy, gradually isolating the French garrison. The decisive moment came in February 1799, when Vido was stormed after heavy artillery fire from Russian ships. Once Vido fell, the French position became untenable. On March 3, 1799, the French commander, General Louis François Jean Chabot, surrendered the island to the allied forces.

The capture of Corfu marked a rare and significant instance of successful cooperation between Russia and the Ottoman Empire, traditional rivals with a long history of conflict. In the aftermath, the Ionian Islands were reorganized into the Septinsular Republic, formally under Ottoman suzerainty but effectively influenced by Russia. This arrangement represented one of the first modern Greek autonomous political entities and foreshadowed later movements for independence in the Balkans. Strategically, the siege weakened French influence in the eastern Mediterranean and demonstrated the growing reach of Russian naval power. Admiral Ushakov’s leadership during the campaign earned him lasting recognition, and the siege remains a notable example of combined naval and amphibious warfare at the turn of the nineteenth century.
