Caesar's Commentaries - De Bello Gallico - The Gallic Wars by Julius Caesar Commentarii de Bello Gallico, also Bellum Gallicum, is Julius Caesar's firsthand account of the Gallic Wars, written as a third-person narrative. In it Caesar describes the battles and intrigues that took place in the nine years he spent fighting the Germanic peoples and Celtic peoples in Gaul that opposed Roman conquest. The character of the First Caesar has perhaps never been worse appreciated than by him who in one sense described it best; that is, with most force and eloquence wherever he really did comprehend it. This was Lucan, who has nowhere exhibited more brilliant rhetoric, nor wandered more from the truth, than in the contrasted portraits of Caesar and Pompey. The famous line, "Nil actum reputans si quid superesset agendum," is a fine feature of the real character, finely expressed.
