Julius Caesar is stabbed to death by a group of conspirators in the Senate, in Act III, scene 1. Casca strikes the first blow, to the neck, and Brutus strikes the last.
The group approaches under the pretext of a petition: Metellus Cimber kneels before Caesar to ask for an end to his brother's exile. Caesar refuses, saying he is as constant as the northern star, and Brutus and Cassius join the petition, which Cinna and Decius also support. Trebonius had already drawn Antony away. When Caesar asks Cinna whether he wants to raise Olympus, Casca cries "Speak, hands, for me!" and wounds him.
Caesar, seeing Brutus among those who strike him, says "Et tu, Brute?" and "Then fall, Caesar!" and dies. The conspirators then proclaim liberty, and Brutus proposes washing their hands in Caesar's blood up to the elbows and going out shouting "peace, liberty."
The play speaks of thirty-three wounds: it is Octavius who says, at Philippi (Act V, scene 1), that his sword will not return to its scabbard until Caesar's wounds are avenged. Antony, in the Forum (Act III, scene 2), points out on the cloak the tear made by Cassius's dagger, Casca's knife, and Brutus's blow.
