Montgomery On the death of Charles IX in 1574,
Montgomery took the opportunity to attempt to seize
Alençon, departing
Carentan with 650 horse hoping to surprise the city. Matignon was ready, and attacked him as he moved from Alençon to raise the siege of
St Lô pinning him down in
Domfront. Defending the town vigorously, while his opponent received reinforcements from Paris, he was eventually subdued, with Matignon promising that his life would be spared. However, Montgomery was the man who had accidentally killed
Henri II and
Catherine de'Medici had not forgiven him. Brought to Paris, she would see him executed on 26 June before a large crowd. Matignons army, now numbering around 7500 marched on Saint-Lô, bringing the siege of the town to a successful conclusion. His operations were almost derailed by a threatened strike from his artillery officers due to lack of pay, however Catherine arranged for the sum to be forwarded to them from Paris. This accomplished Carentan opened its gates to him, and Normandy was subdued.
Return of Henri Henri III who had been in
Polish-Lithuanian Commonwealth as their king, returned to France in early 1575 and was crowned king. To inaugurate his reign he elevated Matignon and
Biron to Marshals with the aim of diluting Retz's influence. He promptly resigned his Marshalate. Displeasure about royal taxation was increasing throughout late 1578, with anger at local estates threatening to spill over into armed revolt. Matignon in his role as governor of lower Normandy wrote to the king informing him of areas where there might be trouble, and further stepped in to stop a disturbance in
Coutances. In December Henri wrote back, indicating his fears that greater trouble was on the horizon in Caen, and to be on the lookout.
Seventh war of religion In 1579,
Condé, frustrated about his failure to re-acquire the governorship of
Picardie, seized the town of
La Fère, initiating the seventh war of religion. Matignon settled in to siege the city for the crown, succeeding in reducing it after ten months. He was joined by a considerable
ligue force under Aumale as he conducted his siege, and perhaps as a result offered generous terms to the besieged, hoping to avoid giving the
ligue political advantage. Aumale fumed when he was made aware of the terms, and stormed out of the royal camp without taking leave of Matignon. In 1581 he accompanied Catherine as she tried to appeal to
Alençon who was determined to take up a role as king of the
Netherlands. At a meeting he warned the duke that his plans were likely to end in disaster. Alençon responded that if not for the presence of his mother he would have Matignon beaten and thrown from a window.
Guyenne In 1583 the governorship of Normandy was re-consolidated into one office, and provided to Henri's favourite,
Anne de Joyeuse, in compensation, Matignon was reassigned to
Guyenne where he and
Épernon were granted the office of lieutenant-generals. In further compensation it was agreed that Matignons son would receive the singular lieutenant-general role of the reunified governorship after
François d'O had a period in the role.
Triumph of the ligue In 1585, the
Catholic ligue led by
Henry I, Duke of Guise successfully forced the capitulation of the crown, in the
Treaty of Nemours into revoking all edicts of pacification, and to accept the
ligue as a mechanism by which Calvinism might be destroyed. As a result, the royal army was now tasked with crushing the forces of
Navarre and Condé. While the forces of the
ligue set to work with zeal, Marshals Matignon and Biron in
Guyenne half heartedly pressed against Navarre. With the
assassination of the duke of Guise by the king in 1588, the king indicated to Navarre he was ready to ally with the
politiques against the ligue, and they met in April 1589, signing an agreement. Matignon at this time held
Bordeaux for the king, but Henri had little territory left aside from that. ==Reign of Henri IV==
