Charles Ogier de Batz de Castelmore, Comte d'Artagnan (c. 1611 Lupiac - 25 June, 1673 Maastricht) served Louis XIV as captain of the Musketeers of the Guard and died at the Siege of Maastricht in the Franco-Dutch War. A fictionalized account of his life by Gatien de Courtilz de Sandras formed the basis for the d'Artagnan Romances of Alexandre Dumas, most famously including The Three Musketeers.
