"He will not surrender the town without orders from the Prince of Navarre.

But if you will grant a fortnight's armistice, he will send a messenger to the prince; and if no answer arrives, or if no succour reaches him at the end of that time, he will surrender; on condition that the garrison shall be permitted to retire, with their horses and arms, and that religious liberty shall be granted to all the inhabitants." The Duc consulted with his generals.

The losses in the attacks had been extremely heavy, and disease was raging in the army and, to Philip's inward surprise and delight, an answer was made that the conditions would be granted, but that only ten days would be given.
He returned with the answer to De Piles, and the armistice was at once agreed upon, six hostages for its proper observance being given on both sides.
On the ninth day Saint Surin, with forty horsemen, dashed through the enemy's lines and rode into the town; thus relieving De Piles from the necessity of surrendering.

The hostages were returned on both sides, and the siege recommenced.
Attack after attack was repulsed, with heavy loss; several of the bravest royalist officers, among them the governor of Brittany, being killed.

The town was valiantly defended until the 2nd of December, when De Piles, satisfied with having detained the royal army seven weeks before the walls, and seeing no hope of relief, surrendered on the same conditions that had before been agreed on.
Its capture had cost the Duc d'Anjou 6000 men, about half of whom had fallen by disease, the rest in the assaults; and the delay had entirely defeated the object of the campaign.
The gates were opened, and the little body of defenders marched out, with colours flying.
