The walls, however, were so strong that there seemed little prospect of success attending such an attempt, and a plan was therefore determined upon by which the enemy might be thrown off their guard.

The assault commenced at three points in the early morning and was continued all day.

No great vigour, however, was shown in these attempts which were repulsed at all points.
At nightfall the assailants drew off to their camp, and Oliver de Clisson, who commanded the town, suffered his weary troops to quit the walls and to seek for refreshment and repose.

The assailants, however, did not disarm, but after a sufficient time had elapsed to allow the garrison to lay aside their armour two strong parties attacked the principal gates of the town, while Sir Walter Manny and the Earl of Oxford moved round to the opposite side with ladders for an escalade.
The plan was successful.

The garrison, snatching up their arms, hurried to repel their attack upon the gates, every man hastening in that direction.
