Here are the words of Plutarch on the assassination of Caesar, from the John Dryden translation, revised by Arthur Hugh Clough in 1864, of Plutarch's Caesar, so you can see the gory details for yourself:
When Caesar entered, the senate stood up to show their respect to him, and of Brutus's confederates, some came about his chair and stood behind it, others met him, pretending to add their petitions to those of Tillius Cimber, in behalf of his brother, who was in exile; and they followed him with their joint supplications till he came to his seat. When he was sat down, he refused to comply with their requests, and upon their urging him further, began to reproach them severally for their importunities, when Tillius, laying hold of his robe with both his hands, pulled it down from his neck, which was the signal for the assault. Casca gave him the first cut, in the neck, which was not mortal nor dangerous, as coming from one who at the beginning of such a bold action was probably very much disturbed. Caesar immediately turned about, and laid his hand upon the dagger and kept hold of it. And both of them at the same time cried out, he that received the blow, in Latin, "Vile Casca, what does this mean?" and he that gave it, in Greek, to his brother, "Brother, help!" Upon this first onset, those who were not privy to the design were astonished and their horror and amazement at what they saw were so great, that they durst not fly nor assist Caesar, nor so much as speak a word. But those who came prepared for the business enclosed him on every side, with their naked daggers in their hands. Which way soever he turned, he met with blows, and saw their swords leveled at his face and eyes, and was encompassed, like a wild beast in the toils, on every side. For it had been agreed they should each of them make a thrust at him, and flesh themselves with his blood; for which reason Brutus also gave him one stab in the groin. Some say that he fought and resisted all the rest, shifting his body to avoid the blows, and calling out for help, but that when he saw Brutus's sword drawn, he covered his face with his robe and submitted, letting himself fall, whether it were by chance, or that he was pushed in that direction by his murderers, at the foot of the pedestal on which Pompey's statue stood, and which was thus wetted with his blood. So that Pompey himself seemed to have presided, as it were, over the revenge done upon his adversary, who lay here at his feet, and breathed out his soul through his multitude of wounds, for they say he received three and twenty.
