The report of this glorious exploit having spread beyond the Rhine, the Suevi, who had come to its banks, returned home. The Ubii, who dwelt near the river, pursued their terrified bands, and slew a considerable number of the fugitives. Cæsar, having concluded two great wars in one single campaign, placed his army in winter quarters among the Sequani rather sooner than the season required--at the beginning of September--and left them under the command of Labienus. He then left, and went to hold the assemblies in Cisalpine Gaul.[237] [Sidenote: Observations.] IX. There are several things worthy of remark in this campaign:-- 1. The resolution taken by Cæsar to gain possession of Besançon, and thus to anticipate Ariovistus. We see the importance which he attaches to that military position as a point of support and of supply. 2. The facility with which a whole legion transforms itself into cavalry. 3. The judicious use which Cæsar makes of his light troops (_alarii_), by assembling them in mass, so that the enemy should believe in a greater number of legions. 4. Lastly, this singular circumstance, that the third line, which serves as reserve and decides the fate of the battle, receives from young P. Crassus, and not from the general-in-chief, the order to attack. The dates of the principal events of this year may be indicated in the following manner:-- Rendezvous of the Helvetii on the banks of the Rhone (the day of the equinox) March 24. Cæsar refuses them a passage through the province April 8. Arrival at the confluence of the Rhone and the Saône of the legions from Italy and Illyria June 7.
