A year after the signing of Sablé, the treaty was reneged upon in favour of a tripartite alliance at Amiens with Burgundy and England.

The town of Sablé was therefore chosen for a summit in 1488 when the duchy was forced to do homage to the King of France for the last time.

Moreover, the duke pledged the territories of Saint Malo, Dinan, Fougères and Saint-Aubin-du-Cormier to be controlled by the French crown.

Also, Francis promised to remove all foreign troops from his territories, as well as ensure to seek Charles's consent before marrying off his daughter, Anne.

In return, Charles removed his forces from Brittany except in the town garrisons of the territories pledged by Francis.
