The Ottoman siege of the city began on 8 July, with landings of some 4,000 Janissaries and 6,000 other troops at Ypsos.
On the evening of the same day, however, Corner's squadron arrived unexpectedly and attacked the Ottoman fleet, despite having only 27 ships to the Ottomans' 62.
The ensuing naval battle was indecisive, but the sudden Venetian attack forced the Ottoman ships to cut their anchors and temporarily abandon their anchorage and interrupt their ferrying of the Ottoman troops.
This bold action demonstrated the Venetians' determination to defend Corfu, and also raised hopes about the island's ability to resist the Ottomans; for a time, it seemed even possible that the Venetian fleet might hinder the passage of fresh Ottoman troops, and allow those already present on the island to be cut off.
As a result, the mood of the population swung into enthusiastic support for the defence, and many hundreds volunteered to assist in building fortifications, man artillery pieces, or enlisted in militias.

On 10 July, the Ottoman ships recommenced landing troops, a process which continued without the Venetians making any attempt to interrupt it.
Clashes with the Canım Hoca Mehmed's men on the island continued over the next few days, as reinforcements started arriving for the defenders and the Ottomans alike: on 18 July Pisani returned to the island with a new, eighty-gun warship, two transports with 1,500 men, and a ship with food, while shortly after the troops of the serasker also began landing on the island.
The Ottoman forces were able to expand their occupation in the interior, pressing the inhabitants of the villages they captured into erecting field works.
On 21 July, the Ottomans reached the suburbs of Mantouki and Gastrades.

On the next day, the first ships of Venice's Christian allies appeared of Cape Lefkimmi in the south: nine ships of the Knights of Malta, the vanguard of a much larger Christian fleet composed of ships from the Papal States, the Republic of Genoa, Spain, and the Grand Duchy of Tuscany.
On 31 July, four Papal, two Genoese, three Tuscan and five Spanish galleys arrived, along with four ships of the line hired by the Pope.
Their arrival helped to prevent the Ottoman fleet from attacking the fortress from the northeast, and kept the sea open for supplies to reach Corfu city.
At the same time, the Ottoman forces on the island were making progress, capturing the fort of the Saviour (San Salvatore) and the hill of Abramios (Monte Abramo) to the west of the city.
On 5 August, the serasker issued a demand for the Venetians' surrender, threatening to massacre the garrison and flatten the city otherwise.
Schulenburg rejected the demand, but the defenders were in dire straits, as they had suffered heavy losses and much of their artillery had been destroyed.
On the same day, the Venetian fleet moved to engage the Ottomans, but at the last moment, the wind shifted, giving the Ottomans the advantage, forcing the Venetians to break off.
Schulemburg proposed a sortie of the garrison for 6 July, but Pisani refused to co-operate and the project was shelved.

On 8 August, the situation began to change in favour of the defenders, as 1,500 troops with ample supplies and ammunition arrived to bolster the garrison, bringing with them news of the Austrian victory at the Battle of Petrovaradin on 5 August.
As a result, on the night of 18/19 August, the Venetians sortied against the Ottoman lines supported by fire from the galleys on both sides of the city.
As the German contingent failed in its objectives, and the sortie was pushed back.
In turn, on the morning of 19 August, the Janissaries launched a mass assault on the fortifications, overrunning the bastion of St. Athanasios and part of the outer fortified belt and reaching the Skarpon Gate, where they hosted their banners.
Schulenburg led a counterattack in person, and managed to push the Ottomans back.
On the next day, a storm broke out that wrought havoc with both fleets; some of the Christian ships unmoored by the winds and thrown towards the shore, while the Ottom
