Seven Years' War: France began an unsuccessful attempt to retake Quebec City, which had been captured by Britain.

The Seven Years' War, 1756 to 1763, was a global war fought by numerous great powers, primarily in Europe, with significant subsidiary campaigns in North America and the Indian subcontinent. The warring states were Great Britain and Prussia fighting against France and Austria, with other countries joining these coalitions: Portugal, Spain, Saxony, Sweden, and Russia. Related conflicts include the Third Silesian War, French and Indian War, Third Carnatic War, Anglo-Spanish War (1762–1763), and Spanish–Portuguese War. Winston Churchill later famously referred to the conflict as the "First World War" due to its truly global scale, with major campaigns spanning four continents.
