Battle of the Chesapeake in the context of "HMS Europa (1765)"

French involvement in the American Revolutionary War of 1775–1783 began in 1776 when the Kingdom of France secretly shipped supplies to the Continental Army of the Thirteen Colonies upon its establishment in June 1775. France was a long-term historical rival with the Kingdom of Great Britain, from which the Thirteen Colonies were attempting to separate. Having lost its own North American colony to Britain in the Seven Years' War, France sought to weaken Britain by helping the American insurgents.

A Treaty of Alliance between the French and the Continental Army followed in 1778, which led to French money, matériel and troops being sent to the United States. An ignition of a global war with Britain started shortly thereafter. Subsequently, Spain and the Dutch Republic also began to send assistance, which, along with other political developments in Europe, left the British with no allies during the conflict (excluding the Hessian mercenaries). Spain openly declared war in 1779, Spain joined its ally France in the war (but did not make a formal treaty with the Americans), and war between the British and Dutch followed soon after.

Lieutenant général des armées navales François Joseph Paul, Comte de Grasse, Marquis of Grasse-Tilly, KM (13 September 1722 – 11 January 1788) was a French naval officer. He is best known for his crucial victory over the Royal Navy at the Battle of the Chesapeake in 1781 during the American Revolutionary War. The battle directly led to the Franco-American victory at the siege of Yorktown and helped secure the independence of the United States.

After the battle, de Grasse returned with his fleet to the Caribbean. In 1782, a British fleet under Admiral George Rodney defeated and captured de Grasse at the Battle of the Saintes. De Grasse was widely criticised for his defeat in the battle. On his return to France in 1784, he blamed his captains for the defeat. A court-martial exonerated all of his captains, effectively ending his naval career.
