His superior airship has the upper hand and severely damages the opposing vessel, but the musketeers use the clouds to rally and counterattack . The fight ends when both ships ram each other, crashing onto Notre Dame . On the roof, d'Artagnan duels and ultimately kills Rochefort . Constance is sent ahead to quietly return the necklace to Queen Anne .

Richelieu, satisfied, offers the musketeers a place in his guards, but they refuse, and Richelieu vows revenge . </P> <P> Meanwhile, Milady is found alive at the English Channel by Buckingham, who declares his intention to exact revenge .
