D'Artagnan was born at the castle of Castelmore near Lupiac in south-western France.
His father, Bertrand de Batz lord of Castelmore, was the son of a newly ennobled merchant, Arnaud de Batz, who purchased the castle of Castelmore.
Charles de Batz went to Paris in the 1630s, using the name of his mother Françoise de Montesquiou d'Artagnan.
D'Artagnan found a way to enter into the Musketeers in 1632 through the support of his uncle, Henri de Montesquiou d'Artagnan or perhaps thanks to the influence of Henri's friend, Monsieur de Tréville (Jean-Armand du Peyrer, Comte de Troisville).
D’Artagnan joined the guards in the mid-1630s and served under Captain des Essarts.
The regiment saw much action in the early 1640s, taking part in sieges at Arras, Aire-sur-la-Lys, la Bassée and Bapaume in 1640–41  and Collioure and Perpignan in 1642.
Whether or not d’Artagnan was personally involved is unclear, but it is likely he took part in some, if not all, of these sieges.
While in the Musketeers, d'Artagnan sought the protection of the influential Cardinal Mazarin, France's principal minister since 1643.
In 1646, the Musketeers company was dissolved, but d'Artagnan continued to serve his protector Mazarin.
