The Siege of Corfu was one of the defining moments of the Seventh Ottoman-Venetian War, showcasing the intense rivalry between the two maritime powers over control of the Ionian Islands. Early in August, the Ottomans, under the command of Grand Vizier Ahmed III, laid siege to the island, which had significant strategic importance for Venice. As the siege progressed, the Venetian defenders, although outnumbered, were resolute. Reports of the Battle of Petrovaradin, where the Ottomans faced a decisive defeat against the Habsburg forces, reached the Venetian command shortly before reinforcements arrived. The favorable news coupled with the naval reinforcements allowed the Venetians to bolster their defenses effectively and counter the Ottoman advances.

As Ottoman forces prepared for a final assault on the city, the unexpected arrival of Venetian ships caught the besieging forces off guard. This moment marked a turning point in the siege, shifting momentum back to the Venetians, who had been holding on under dire circumstances. By the end of August, the Ottomans, realizing their precarious position due to the dual threats of well-organized Venetian defense and a newly fortified fleet, decided to withdraw their forces and abandon the siege altogether. This retreat not only preserved Venetian rule over Corfu but also maintained their influence in the Ionian Islands, which were crucial for trade and naval operations in the Mediterranean.
