During the assassination, senator Tillius Cimber grabbed hold of Caesar's toga and pulled it down from his neck, which signalled to the other conspirators that it was time to attack. According to the historian Suetonius, Caesar shouted out in Latin, "Ista quidem vis est!" ("Why, this is violence!" or "But this is violence!") when his toga was ripped down from his shoulder. Suetonius further writes that Caesar spoke no more after this, besides a groan after the first knife blow, and died without saying anything.
