Hostilities lapsed for years until trouble between England and Spain led to the so-called War of Jenkins's Ear (1739–41), which merged into the War of the Austrian Succession (1740–48). The American phase, King George's War, did not begin until 1744, when the French made an unsuccessful assault on Port Royal. The next year, a Massachusetts-planned expedition under William Pepperrell with a British fleet under Sir Peter Warren took Louisburg. Border warfare was severe but not conclusive. The Treaty of Aix-la-Chapelle (1748) returned Louisburg to France, but the hostile feelings that had been aroused did not die.
