Four hundred men occupied this post.
The Vendeans had no axes to cut down the palisades, nor powder to blow then in.

They were therefore obliged to content themselves with a musketry fire against it.

As the garrison were well supplied with ammunition, and kept up a constant fire, they suffered heavily.
When night came, the Vendeans scattered among the houses to find food, fire, and shelter; and all night the batteries on the heights played upon them.
In the morning the Republicans redoubled their fire.

It became evident that the town itself could not be taken, and the mass of the Vendeans, without orders from their chiefs, began to retire, and in a short time the whole were in rapid retreat to Avranches.
There the cry was raised, "Back to La Vendee!" La Rochejaquelein, after halting his force on the main road a few hours, called upon the men to follow him to Caen; but only one thousand did so.

On arriving at a village he learned that the bulk of the army, instead of being behind him, had marched towards Pontorson.
