The governor of the fortress convened a council of war. As there was no hope of a relief army and he feared pillages and massacres in the city after a takeover, he started to negotiate a surrender. These negotiations did not bring results, and the gun fire from both sides became heavier than ever. In the smaller sites of the siege, especially in the area of the castle, the attackers were making breaches. In the end it was clear to the defenders that they could not hold out. On 3 June they raised a white flag and asked for negotiations. Both sides ceased fire, and soon negotiated an honourable surrender.
