the pensions that would be lost because of conflict with France and to pay the past debts that would be forfeit; to seal the alliance, he also agreed to marry Henry's only daughter, Mary. In July, the English raided Morlaix and in September an English army marched from Calais, burning and looting the countryside in an unsuccessful attempt to engage the French in battle. To raise money, Francis pursued a lawsuit against Charles III, Duke of Bourbon, who had received the majority of his holdings through his marriage to Suzanne, Duchess of Bourbon. After Suzanne's death, Louise of Savoy, her sister and the king's mother, insisted that the territories in question should pass to her because of her closer kinship to the deceased. Francis was confident that seizing the disputed lands would improve his own financial position sufficiently to continue the war and began to confiscate portions of them in Louise's name. Bourbon, angered by this treatment and increasingly isolated at court, sought redress by making overtures to Charles V. The death of Doge Antonio Grimani brought Andrea Gritti, a veteran of the War of the League of Cambrai, to power in Venice. He quickly began negotiations with the Emperor and on 29 July 1523 concluded the Treaty of Worms, which removed the Republic from the war. Bourbon continued his scheming with Charles, offering to begin a rebellion against Francis in exchange for money and German troops. When Francis, who was aware of the plot, summoned him to Lyon in October, he feigned illness and failed to appear. Francis ordered as many of Bourbon's associates as could be captured to be brought to justice after the Duke reached Imperial territory and openly entered the Emperor's service. Charles then invaded southern France over the Pyrenees. Lautrec successfully defended Bayonne against the Spanish, but Charles was able to recapture Fuenterrabia in February 1524. On 19 September 1523, an English army under the Duke of Suffolk advanced into Picardy from Calais. The French, stretched thin by the Imperial attack, were unable to resist, and Suffolk soon advanced past the Somme, devastating the countryside in his wake and stopping only from Paris. When Charles failed to support the English offensive, Suffolk—unwilling to risk an attack on the French capital—turned away from Paris on 30 October, returning to Calais by mid-December. Francis now turned his attention to Lombardy. In September 1523, a French army under
