Jacques François de Pérusse des Cars[Note 1] (November 1738 – 12 April 1782) was a French Navy officer who was a great-grandson of King James II of England.

[3] In 1780, he captained the frigate Prudente,[7] cruising from Saint-Servan to Saint-Malo, Cherbourg and Brest.

In the opening of the Battle of the Saintes, [11] at 9 am,[12] he was wounded by a musket ball, and had to climb down to the deck, where he continued to command.

He was then mortally wounded by a large-calibre musket ball, and died shortly afterwards on 12 April 1782.

[13] Des Cars' defence of Glorieux was later lauded in the subsequent inquiry into the battle.
