The three Musketeers and d’Artagnan return to the bastion and collect the weapons from the corpses of the fallen soldiers, while a servant named Grimaud prepares their breakfast. They tell d’Artagnan about Milady’s plans. When a group of enemy soldiers approaches, the Musketeers shoot at them while continuing to talk—a funny shootout that ends when the attackers come close enough for the Musketeers to push over the wall of the disintegrating bastion onto them.

Porthos suggests strangling Milady, but Aramis rejects killing a woman. They agree to inform the queen of the plot against the duke, and to write to Lord de Winter about his dangerous sister-in-law.

Another unit arrives to fight them, so the Musketeers prop up the bodies of dead soldiers to look alive and armed, escaping as the unit shoots at these decoys. Back in camp, the Musketeers are lauded as heroes. D’Artagnan decides to sell the diamond ring the queen gave him to fund the next mission. Treville hears of the Musketeers triumph and promotes d’Artagnan to a Musketeer.
