[Sidenote: Account of northern nations.] [Sidenote: Their strange customs.] [Sidenote: Well-trained horses.]
Caesar gives, in his narrative, very extraordinary accounts of the customs and modes of life of some of the people that he encountered. There was one country, for example, in which all the lands were common, and the whole structure of society was based on the plan of forming the community into one great martial band. The nation was divided into a hundred cantons, each containing two thousand men capable of bearing arms. If these were all mustered into service together, they would form, of course, an army of two hundred thousand men. It was customary, however, to organize only one half of them into an army, while the rest remained at home to till the ground and tend the flocks and herds. These two great divisions interchanged their work every year, the soldiers becoming husbandmen, and the husbandmen soldiers. Thus they all became equally inured to the hardships and dangers of the camp, and to the more continuous but safer labors of agricultural toil. Their fields were devoted to pasturage more than to tillage, for flocks and herds could be driven from place to place, and thus more easily preserved from the depredations of enemies than fields of grain. The children grew up almost perfectly wild from infancy, and hardened themselves by bathing in cold streams, wearing very little clothing, and making long hunting excursions among the mountains. The people had abundance of excellent horses, which the young men were accustomed, from their earliest years, to ride without saddle or bridle, the horses being trained to obey implicitly every command. So admirably disciplined were they, that sometimes, in battle, the mounted men would leap from their horses and advance as foot soldiers to aid the other infantry, leaving the horses to stand until they returned. The horses would not move from the spot; the men, when the object for which they had dismounted was accomplished, would come back, spring to their seats again, and once more become a squadron of cavalry.
[Sidenote: Caesar's popularity with the army.] [Sidenote: Caesar's military habits.] [Sidenote: His bridge across the Rhine.]
Although Caesar was very energetic and decided in the government of his army, he was extremely popular with his soldiers in all these campaigns. He exposed his men, of course, to a great many privations and hardships, but then he evinced, in many cases, such a willingness to bear his share of them, that the men were very little inclined to complain. He moved at the head of the column when his troops were advancing on a march, generally on horseback, but often on foot; and Suetonius says that he used to go bareheaded on such occasions, whatever was the state of the weather, though it is difficult to see what the motive of this apparently needless exposure could be, unless it was for effect, on some special or unusual occasion. Caesar would ford or swim rivers with his men whenever there was no other mode of transit, sometimes supported, it was said, by bags inflated with air, and placed under his arms. At one time he built a bridge across the Rhine, to enable his army to cross that river. This bridge was built with piles driven down into the sand, which supported a flooring of timbers. Caesar, considering it quite an exploit thus to bridge the Rhine, wrote a minute account of the manner in which the work was constructed, and the description is almost exactly in accordance with the principles and usages of modern carpentry.
[Sidenote: System of posts.] [Sidenote: Their great utility.]
After the countries which were the scene of these conquests were pretty well subdued, Caesar established on some of the great routes of travel a system of posts, that is, he stationed supplies of horses at intervals of from ten to twenty miles along the way, so that he himself, or the officers of his army, or any couriers whore he might have occasion to send with dispatches could travel with great speed by finding a fresh horse ready at every stage. By this means he sometimes traveled himself a hundred miles in a day. This system, thus adopted for military purposes in Caesar's time, has been continued in almost all countries of Europe to the present age, and is applied to traveling in carriages as well as on horseback. A family party purchase a carriage, and arranging within it all the comforts and conveniences which they will require on the journey, they set out, taking these post horses, fresh at each village, to draw them to the next. Thus they can go at any rate of speed which they desire, instead of being limited in their movements by the powers of endurance of one set of animals, as they would be compelled to be if they were to travel with their own. This plan has, for some reason, never been introduced into America, and it is now probable that it never will be, as the railway system will doubtless supersede it.
[Sidenote: Caesar's invasion of Britain.] [Sidenote: His pretext for it.]
One of the most remarkable of the enterprises which Caesar undertook during the period of these campaigns was his excursion into Great Britain. The real motive of this expedition was probably a love of romantic adventure, and a desire to secure for himself at Rome the glory of having penetrated into remote regions which Roman armies had never reached before. The pretext, however, which he made to justify his invading the territories of the Britons was, that the people of the island were accustomed to come across the Channel and aid the Gauls in their wars.
[Sidenote: Caesar consults the merchants.]
In forming his arrangements for going into England, the first thing was, to obtain all the information which was accessible in Gaul in respect to the country. There were, in those days, great numbers of traveling merchants, who went from one nation to another to purchase and sell, taking with them such goods as were most easy of transportation. These merchants, of course, were generally possessed of a great deal of information in respect to the countries which they had visited, and Caesar called together as many of them as he could find, when he had reached the northern shores of France, to inquire about the modes of crossing the Channel, the harbors on the English side, the geographical conformation of the country, and the military resources of the people. He found, however, that the merchants could give him very little information. They knew that Britain was an island, but they did not know its extent or its boundaries; and they could tell him very little of the character or customs of the people. They said that they had only been accustomed to land upon the southern shore, and to transact all their business there, without penetrating at all into the interior of the country.
[Sidenote: Volusenus.]
Caesar then, who, though undaunted and bold in emergencies requiring prompt and decisive action, was extremely cautious and wary at all other times, fitted up a single ship, and, putting one of his officers on board with a proper crew, directed him to cross the Channel to the English coast, and then to cruise along the land for some miles in each direction, to observe where were the best harbors and places for landing, and to examine generally the appearance of the shore. This vessel was a galley, manned with numerous oarsmen, well selected and strong, so that it could retreat with great speed from any sudden appearance of danger The name of the officer who had the command of it was Volusenus. Volusenus set sail, the army watching his vessel with great interest as it moved slowly away from the shore. He was gone five days, and then returned, bringing Caesar an account of his discoveries.
