In Paris, d'Artagnan visits Monsieur de Tréville at the headquarters of the Musketeers, but without the letter, Tréville politely refuses his application. He does, however, write a letter of introduction to an academy for young gentlemen which may prepare his visitor for recruitment at a later time. From Tréville's window, d'Artagnan sees Rochefort passing in the street below and rushes out of the building to confront him, but in doing so he offends three Musketeers, Athos, Porthos, and Aramis, who each demand satisfaction; d'Artagnan must fight a duel with all of them that afternoon.As d'Artagnan prepares himself for the first duel, he realizes that Athos's seconds are Porthos and Aramis, who are astonished that the young Gascon intends to duel them all. As d'Artagnan and Athos begin, Cardinal Richelieu's guards appear and attempt to arrest d'Artagnan and the three Musketeers for illegal dueling. Although they are outnumbered four to five, the four men win the battle. D'Artagnan seriously wounds Jussac, one of the Cardinal's officers and a renowned fighter. After learning of this, King Louis XIII appoints d'Artagnan to Des Essart's company of the King's Guards and gives him forty pistoles.
