Francis could not afford to resume a large-scale war, and Henry was concerned only for the disposition of Boulogne. Negotiations between the two resumed on 6 May. On 7 June 1546, the Treaty of Ardres—also known as the Treaty of Camp—was signed by Claude d'Annebault, Pierre Ramon, and Guillaume Bochetel on behalf of Francis, and Viscount Lisle, Baron Paget and Nicholas Wotton on behalf of Henry. By its terms, Henry would retain Boulogne until 1554, then return it in exchange for two million écus; in the meantime, neither side would construct fortifications in the region, and Francis would resume payment of Henry's pensions. Upon hearing the price demanded for Boulogne, the Imperial ambassador told Henry that the city would remain in English hands permanently.
