The long British naval blockade of French ports had sapped the morale of the French populace. Morale declined further when news of defeat in the Battle of Signal Hill in Newfoundland reached Paris. After Russia's about-face, Sweden's withdrawal and Prussia's two victories against Austria, Louis XV became convinced that Austria would be unable to re-conquer Silesia (the condition for which France would receive the Austrian Netherlands) without financial and material subsidies, which Louis was no longer willing to provide. He therefore made peace with Frederick and evacuated Prussia's Rhineland territories, ending France's involvement in the war in Germany.
