 A truce at Nice in 1538 on the basis of "uti possidetis" ended the war but lasted only a short time.War resumed in 1542, with Francis now allied with Ottoman Sultan Suleiman I and Charles once again allied with Henry VIII.Despite the conquest of Nice by a Franco-Ottoman fleet, the French could not advance toward Milan, while a joint Anglo-Imperial invasion of northern France, led by Charles himself, won some successes but was ultimately abandoned, leading to another peace and restoration of the "status quo ante bellum" in 1544.
