[Act III, Scene ii]—[Scene iii]. The orations of Antony, in vivid contrast to the conciliatory but unimpassioned speeches of Brutus, fire the people and liberate fresh forces in the falling action. Brutus and Cassius have to fly the city, riding "like madmen through the gates of Rome." In unreasoning fury the mob tears to pieces an innocent poet who has the same name as a conspirator.
[Act IV, Scene i]. Antony, Octavius, and Lepidus, having formed a triumvirate of which Antony is the master spirit, agree on a proscription list and join forces against Brutus and Cassius, who "are levying powers."
[Act IV, Scene ii]. Brutus and Cassius, long parted by pride and obstinacy, meet to discuss a plan of action.
[Act IV, Scene iii]. This is one of the most famous individual scenes in Shakespeare (see note, page 123). Its intensely human interest is always conceded, but its dramatic propriety, because of what seems a 'dragging' tendency, has been often questioned. The scene opens with Brutus and Cassius bandying recriminations, and the quarrel of the two generals bodes disaster to their cause. As the discussion proceeds, they yield points and become reconciled. Brutus then quietly but with peculiar pathos tells of Portia's death by her own hand. In all the great tragedies, with the notable exception of Othello, when the forces of the resolution, or falling action, are gathering towards the dénouement, Shakespeare introduces a scene which appeals to an emotion different from any of those excited elsewhere in the play. "As a rule this new emotion is pathetic; and the pathos is not terrible or lacerating, but, even if painful, is accompanied by the sense of beauty and by an outflow of admiration or affection, which come with an inexpressible sweetness after the tension of the crisis and the first counter-stroke. So it is with the reconciliation of Brutus and Cassius, and the arrival of the news of Portia's death."—Bradley. While the shadow of her tragic passing overhangs the spirits of both, Brutus overhears the shrewd, cautious counsel of Cassius and persuades him to assent to the fatal policy of offering battle at Philippi. That night the ghost of Cæsar appears to Brutus.
[Act V, Scene i]. The action now falls rapidly to the quick, decisive movement of the dénouement. The antagonists are now face to face. Brutus and Cassius have done what Antony and Octavius hoped that they would do. The opposing generals hold a brief parley in which Brutus intimates that he is willing to effect a reconciliation, but Antony rejects his proposals and bluntly charges him and Cassius with the wilful murder of Cæsar. Cassius reminds Brutus of his warning that Antony should have fallen when Cæsar did. Antony, Octavius, and their army retire, and the scene closes with the noble farewell without hope between Brutus and Cassius.
[Act V, Scene ii]. The opposing armies meet on the field, and a final flare-up of hope in the breast of Brutus is indicated by his spirited order to Messala to charge. The scene implies that Cassius was defeated by being left without support by Brutus.
V. Dénouement, Catastrophe, or Conclusion (The Knot Untied)
[Act V, Scene iii]. The charge ordered by Brutus has been successful, and Octavius has been driven back, but Cassius is thus left unguarded, and Antony's forces surround him. He takes refuge on a hill and sends Titinius to see "whether yond troops are friend or enemy." Believing Titinius to be slain, he begs Pindarus to stab him, and Cassius dies "even with the sword that kill'd" Cæsar. With the same sword Titinius then slays himself, and Brutus, when Messala bears the news to him, exclaims in words that strike the keynote of the whole falling action and dénouement:
