With the personal appearance of King John II of France at the siege, the English garrison surrendered.

The French did not take any initiative to attack the city because they lacked large enough siege engines to break the walls of Saint-Jean-d'Angély.

The town was surrounded and trade routes blocked to starve the English garrison into surrendering.

An English relief force led by the Seneschal of Gascony, John de Cheverston and Arnaud-Amanieu, was intercepted by a French detachment of the siege army.

In August 1351, with the presence of the King of France, the inhabitants opened the gates of Saint-Jean-d'Angély to the French.
