French ship Invincible (1780)

Invincible was a first-rate ship of the line of the French Royal Navy.

Built on plans by Francois Guillaume Clairin Deslauriers at Rochefort as part of the French naval mobilisation for the American War of Independence, she was a sister-ship of Royal Louis.

She was built within 13 month and completed in May 1780.

American War of Independence
In 1781, stationed in the Antilles, she picked a British convoy. In 1782 she was ordered to Gibraltar, in Lamotte-Picquet's squadron. (Comte de la Motte was her captain April 1781–April 1783). She took part in the Battle of Cape Spartel, where she attacked the rear of the British squadron.

She was refitted several time (1781, 1784 and 1795) until her career came to an end in 1807 when she was disarmed and finally broken up in 1808 at Brest. Her replacement was the Commerce de Marseille of 118 guns.
