Henry, Isabella, Louis, Guala and William came to agreement on the final Treaty of Lambeth, also known as the Treaty of Kingston, on 12 and 13 September. The treaty was similar to the first peace offer, but excluded the rebel clergy, whose lands and appointments remained forfeit. Louis accepted a gift of £6,666 to speed his departure from England, and promised to try to persuade King Philip to return Henry's lands in France. Louis left England as agreed and joined the Albigensian Crusade in the south of France.
