At another part of the field, Cassius has caught one of his ensigns (a flag-bearer) trying to retreat. He killed him and took the flag himself. Titinius points out that things aren’t going so well on the battlefield. Brutus’ men attacked Octavius’ men too early.
Pindarus suddenly enters and tells Cassius to run away. Antony’s men have made it to their tents. Cassius assures him that he is okay parched on top of this hill.
Cassius, then, instructs Titinius to take his horse and ride to a group of troops they see in the distance. He wants to figure out if they’re friends or enemies. Titinius does so. Cassius has bad eyesight, so Pindarus has to tell Cassius what he observes.
Pindarus watches as Titinius is surrounded by the troops. Titinius gets off his horse, as do a few of the other men. The troops shout for joy.
Cassius believes Titinius, his best friend, has been captured by the enemy. Cassius is now short on hope. Cassius decides it’s time to die. Cassius promises Pindarus, his servant, his freedom if he kills him. Pindarus takes Cassius’ dagger, the same dagger used to stab Caesar. Pindarus, then, plunges it into Cassius’ heart. Pindarus makes it clear that he would rather have remained a servant to Cassius than have killed him. He leaves the area, promising to leave Rome.
Messala and Titinius then enter the scene. Messala reveals that Octavius’ army has been beaten by Brutus’ army, while Cassius army has been defeated by Antony’s army. The two men are stunned to find Cassius dead. They realize that it was in error that he killed himself. Titinius has Messala go tell Brutus of Cassius’ death.
Titinius, alone with Cassius’ body, reveals that the troops that he encountered were of Brutus’ army. They cheered and embraced Titinius in their victory over Octavius. Titinius knows that Cassius must have misconstrued his observations. He probably assumed that Titinius had been captured.
The troops even gave Titinius a garland, a gift from Brutus. It was to be sent over to Cassius as a celebratory gesture. Titinius adorns Cassius’ body with the garland. Then, he takes Cassius’ dagger and plunges it within his own heart.
Before long, Brutus and his entourage enter the scene. They are stunned to find Titinius dead alongside Cassius. Brutus wants to make funeral arrangements elsewhere so the funerals don’t discourage the soldiers. For the time being, their focus will remain on the battlefield.
