Lewis, dreading an attack, sent the archbishop of Sens and the count of Blois to the English camp, and desired that next day should be appointed for a conference, in order to establish a general peace, and terminate the difference between Henry and his sons.

The king, who passionately desired this accommodation, and suspected no fraud, gave his consent; but Lewis, that morning, obliging the garrison to surrender, according to the capitulation, set fire to the place, and began to retire with his army.

Henry, provoked at this artifice, attacked the rear with vigor, put them to rout, did some execution, and took several prisoners.

The French army, as their time of service was now expired, immediately dispersed themselves into their several provinces, and left Henry free to prosecute his advantages against his other enemies.
The nobles of Brittany, instigated by the earl of Chester and Ralph de Fougeres, were all in arms; but their progress was checked by a body of Brabancons, which the king, after Lewis's retreat, had sent against them.

The two armies came to an action near Dol, where the rebels were defeated, fifteen hundred killed on the spot, and the leaders, the earls of Chester and Fougeres, obliged to take shelter in the town of Dol.
Henry hastened to form the siege of that place, and carried on the attack with such ardor, that he obliged the governor and garrison to surrender themselves prisoners.
