september 1357 negotiations began in london between the english government and king john ii, who was still a prisoner. philip had attempted to persuade edward that the release of his brother charles should be one of the conditions for a truce with france, but met only evasions. 9 november 1357 charles of navarre escaped from his prison at arleux, three weeks later he was received as a hero returned by a paris increasingly hostile to the dauphin's government. this sped up the proceedings considerably and the kings agreed to a draft treaty, which among other things, provided that philip of navarre should be restored to all that he had held in france before the outbreak of the civil war. peace between france and england was however not in the interest of the king of navarre who relied on the continued political instability to achieve his political ambitions.
