The Spanish wanted to cut the French supply route. They therefore had been attempting to retake Maastricht ever since its fall. The Prince-Bishopric of Liège refusing to join the anti-French coalition, the Spanish tried to support an anti-French uprising  and took military control of the cities of Huy and Dinant. Finally on 31 March 1675, just when an anti-French uprising seemed most imminent, Maastricht sent a garrison of 1,500 soldiers to the city of Liège. From France, a fresh army marched in and retook Dinant  and Huy . Likewise the town of Limbourg was taken by the French after a siege lasting from 13 June until 21 June 1675. Meanwhile, Turenne was trying to protect the Alsace from invasion by Montecuccoli. On 27 July 1675, Turenne caught Montecuccoli's army . However, during an Imperial artillery barrage, a cannonball landed among a group of French officers and killed Turenne. Though defeated in this battle, Montecuccoli and his imperial forces were victorious in the following campaign, driving the French back to the Vosges mountains. Meanwhile, Charles IV and the duke of Brunswick-Lüneburg managed to defeat a French army in the Battle of Konzer Brücke. There were two other significant changes in the cast of military leaders during the year. On 17 August 1675, Charles IV died and was succeeded by his son, Charles V. He became the main Imperial commander and in this year managed to win the Siege of Philippsburg against the French. The city surrendered in September. At the end of the campaign season the Great Condé was forced to retire from all military duties because of his infirmities. After eleven years in retirement, he died on 11 December 1686.
