Siege of Roche-au-Moine

The Siege of Roche-au-Moine was a siege between the Kingdom of France and the Kingdom of England in 1214. John besieged the castle but retreated in the face of Prince Louis of France's relief army after he was refused support from Angevin nobles.

Siege
In 1214 John began his final campaign to reclaim Normandy from Philip. John was optimistic, as he had successfully built up alliances with the Emperor Otto, Renaud of Boulogne and Count Ferdinand of Flanders; he was enjoying papal favour; and he had successfully built up substantial funds to pay for the deployment of his experienced army. Nonetheless, when John left for Poitou in February 1214, many barons refused to provide military service; mercenary knights had to fill the gaps. John's plan was to split Philip's forces by pushing north-east from Poitou towards Paris, whilst Otto, Renaud and Ferdinand, supported by William Longespée, marched south-west from Flanders.

The first part of the campaign went well, with John outmanoeuvring the forces under the command of Prince Louis and retaking the county of Anjou by the end of June. John besieged the castle of Roche-au-Moine, a key stronghold, forcing Louis to advance against John's larger army. The local Angevin nobles refused to fight with the king; left at something of a disadvantage, John had to retreat back to La Rochelle.

Aftermath
Shortly afterwards, Philip won the hard-fought battle of Bouvines in the east against Otto and John's other allies, bringing an end to John's hopes of retaking Normandy. A peace agreement was signed in which John returned Anjou to Philip and paid the French king compensation; the truce was intended to last for six years. John arrived back in England in October.
