He has likewise left Commentaries of his own actions both in the war in Gaul, and in the civil war with Pompey; for the author of the Alexandrian, African, and Spanish wars is not known with any certainty. Some think they are the productions of Oppius, and some of Hirtius; the latter of whom composed the last book, which is imperfect, of the Gallic war. Of Caesar's Commentaries, Cicero, in his Brutus, speaks thus: " He wrote his Commentaries in a manner deserving of great approbation: they are plain, precise, and elegant, without any affectation of rhetorical ornament. In having thus prepared materials for others who might be inclined to write his history, he may perhaps have encouraged some silly creatures to enter upon such a work, who will needs be dressing up his actions in all the extravagance of bombast; but he has discouraged wise men from ever attempting the subject." Hirtius delivers his opinion of these Commentaries in the following terms: "So great is the approbation with which they are universally perused, that, instead of rousing, he seems to have precluded, the efforts of any future historian. Yet, with respect to this work, we have more reason to admire him than others; for they only know how well and correctly he has written, but we know, likewise, how easily and quickly he did it."

Pollio Asinius thinks that they were not drawn up with much care, or with a due regard to truth; for he insinuates that Caesar was too hasty of belief in regard to what was performed by others under his orders; and that, he has not given a very faithful account of his own acts, either by design, or through defect of memory; expressing at the same time an opinion that Caesar intended a new and more correct edition. He has left behind him likewise two books on Analogy, with the same number under the title of Anti-Cato, and a poem entitled The .Itinerary. Of these books, he composed the first two in his passage over the Alps, as he was returning to the army after making his circuit in Hither-Gaul; the second work about the time of the battle of Munda; and the last during the four-and-twenty days he employed in his journey from Rome to Farther-Spain. There are extant some letters of his to the senate, written in a manner never practised by any before him; for they are distinguished into pages in the form of a memorandum book: whereas the consuls and commanders till then, used constantly in their letters to continue the line quite across the sheet, without any folding or distinction of pages. There are extant likewise some letters from him to Cicero, and others to his friends, concerning his domestic affairs; in which, if there was occasion for secrecy, he wrote in cyphers; that is, he used the alphabet in such a manner, that not a single word could be made out. The way to decipher those epistles was to substitute the fourth for the first letter, as d for a, and so for the other letters respectively. Some things likewise pass under his name, said to have been written by him when a boy, or a very young man; as the Encomium of Hercules, a tragedy entitled (Edipus, and a collection of Apophthegms; all which Augustus forbad to be published, in a short and plain letter to Pompeius Macer, who was employed by him in the arrangement of his libraries.

He was perfect in the use of arms, an accomplished rider, and able to endure fatigue beyond all belief. On a march he used to go at the head of his troops, sometimes on horseback, but oftener on foot, with his head bare in all kinds of weather. He would travel post in a light carriageMeritoria rheda; a light four-wheeled carriage, apparently hired either for the journey or from town to town. They were tolerably commodious, for Cicero writes to Atticus, (v. 17.)Hanc eptstolam dictavi sedens in rheda, cum in castra proficiscerer. without baggage, at the rate of a hundred miles a day; and if he was stopped by floods in the rivers, he swam across, or floated on skins inflated with wind, so that he often anticipated intelligence of his movements. Plutarch informs us that Caesar travelled with such expedition, that he reached the Rhone on the eighth day after he left Rome.

In his expeditions, it is difficult to say whether his caution or his daring was most conspicuous. He never marched his army by roads which were exposed to ambuscades, without having previously examined the nature of the ground by his scouts. Nor did he cross over to Britain, before he had carefully examined, in person, Caesar tells us himself that he employed C. Volusenus to reconnoitre the coast of Britain, sending him forward in a long ship, with orders to return and make his report before the expedition sailed. the navigation, the harbours, and the most convenient point of landing in the island. When intelligence was brought to him of the siege of his camp in Germany, he made his way to his troops, through the enemy's stations, in a Gaulish dress. He crossed the sea from Brundisium and Dyrrachium, in the winter, through the midst of the enemy's fleets; and the troops, under orders to join him, being slow in their movements, notwithstand, ing repeated messages to hurry them, but to no purpose, he at last went privately, and alone, aboard a small vessel in the night time, with his head muffled up; nor did he make himself known, or suffer the master to put about, although the wind blew strong against them, until they were ready to sink.

He was never deterred from any enterprise, nor retarded in the prosecution of it, by superstition.Religione; that is, the omens being unfavourable. When a victim, which he was about to offer in sacrifice, made its escape, he did not therefore defer his expedition against Scipio and Juba. And happening to fall, upon stepping out of the ship, he gave a lucky turn to the omen, by exclaiming, "I hold thee fast, Africa." To chide the prophecies which were spread abroad, that the name of the Scipios was, by the decrees of fate, fortunate and invincible in that province, he retained in the camp a profligate wretch, of the family of the Cornelii, who, on account of his scandalous life, was surnamed Salutio.

He not only fought pitched battles, but made sudden attacks when an opportunity offered; often at the end of a march, and sometimes during the most violent storms, when nobody could imagine he would stir. Nor was he ever backward in fighting, until towards the end of his life. He then was of opinion, that the oftener he had been crowned with success, the less he ought to expose himself to new hazards; and that nothing he could gain by a victory would compensate for what he might lose by a miscarriage. He never defeated the enemy without driving them from their camp; and giving them no time.to rally their forces. When the issue of a battle was doubtful, he sent away all the horses, and his own first, that having no means of flight, they might be under the greater necessity of standing their ground.
