Edward's army laid siege to the port in September 1346. With French finances and morale at a low ebb after Crécy, Philip failed to relieve the town, and the starving defenders surrendered on 3 August 1347. Following further inconclusive military manoeuvres by each side for four weeks, and given that both were financially exhausted, emissaries despatched by Pope Clement VI found willing listeners. By 28 September the Truce of Calais, intended to bring a temporary halt to the fighting, had been agreed. This strongly favoured the English, confirming them in possession of all of their territorial conquests. It was to run for nine months to 7 July 1348, but was extended repeatedly over the years until it was formally set aside in 1355. The truce did not stop ongoing naval clashes between the two countries, nor small-scale fighting in Gascony and Brittany.
