In addition to the fire from the enemy's guns, they were exposed to a rain of arrows, and at the end of two days and nights they were utterly worn out and exhausted, and protested that they could do no more.

Pisani, who had himself laboured among them in the thickest of the danger, strove to keep up their spirits by pointing out the importance of their work, and requested the doge to swear on his sword that, old as he was, he would never return to Venice unless Chioggia was conquered.
The doge took the oath, and for the moment the murmuring ceased; and, on the night of the 24th, the channel of Chioggia was entirely choked from shore to shore.

On that day, Corbaro succeeded in sinking two hulks in the passage of Brondolo.

Doria, who had hitherto believed that the Venetians would attempt nothing serious, now perceived for the first time the object of Pisani, and despatched fourteen great galleys to crush Corbaro, who had with him but four vessels.

Pisani at once sailed to his assistance, with ten more ships, and the passage was now so narrow that the Genoese did not venture to attack, and Corbaro completed the operation of blocking up the Brondolo passage.
