Marus Petreius, a centurion of the same legion, after attempting to hew down the gates, was overpowered by numbers, and, despairing of his safety, having already received many wounds, said to the soldiers of his own company who followed him: “Since I can not save you as well as myself, I shall at least provide for your safety, since I, allured by the love of glory, led you into this danger, do you save yourselves when an opportunity is given.”
At the same time he rushed into the midst of the enemy, and slaying two of them, drove back the rest a little from the gate. When his men attempted to aid him, “In vain,” he says, “you endeavor to procure me safety, since blood and strength are now failing me, therefore leave this, while you have the opportunity, and retreat to the legion.”
Thus he fell fighting a few moments after, and saved his men by his own death.

This is quite Hollywood moment. I somehow doubt that Julius Caesar was good chronicler.: the fighting surely did not stop for few seconds to allow him clear enunciation and eloquent speech, especially if he was short of breath and in great pain.
