Charles de Batz de Castelmore, also known as d'Artagnan and later Count d'Artagnan, was a French Musketeer who served Louis XIV as captain of the Musketeers of the Guard. He died at the siege of Maastricht in the Franco-Dutch War. A fictionalised account of his life by Gatien de Courtilz de Sandras formed the basis for the d'Artagnan Romances of Alexandre Dumas père, most famously including The Three Musketeers (1844). The heavily fictionalised version of d'Artagnan featured in Dumas' works and their subsequent screen adaptations is now far more widely known than the real historical figure.
