Jean Baptiste Charles Henri Hector, Comte d'Estaing was born November 24, 1729, in the south-central region of France. Coming from a lifelong military family, his father was a lieutenant for the French Army. At nine, he was placed into the musketeers and rose through the ranks, becoming a lieutenant at seventeen.
In 1746, his regiment saw action in the War of Austrian Succession. He was promoted to colonel and wounded during a siege.
His regiment sailed to Cuddalore, British-occupied South India during the French and Indian War in 1755, and engaged in combat against the Royal Navy. After placing a siege on British territory, the French and the Royal navy faced in combat. D'Estaing was quickly surrounded by the British, wounded twice, forced to surrender, and taken prisoner by the British governor.
Upon release, he continued his service by commanding fleets for the French East India Company. After the French and Indian War, d'Estaing served as governor of the Caribbean Leeward Islands for two years (1764-1766). He returned to France and, in 1777, was appointed Vice Admiral of the Asian and American seas.
The following year, in 1778, France signed the Franco-American alliance, agreeing to support the colonies in the American Revolution. Determined to help the colonies, d'Estaing left France with sixteen ships—mostly ships of the line—and 4,000 men. He arrived in July and began blockading William Howe's fleet in New York Harbor.
