Caesar sent again to Ariovistus to say, that since he was so unmindful of his obligations to the Roman people as to refuse an interview with him on business of common interest, he would state the particulars that he required of him. The Aeduans, he said, were now his allies, and under his protection; and Ariovistus must send back the hostages which he held from them, and bind himself henceforth not to send any more troops across the Rhine, nor make war upon the Aeduans, or injure them in any way. If he complied with these terms, all would be well. If he did not, Caesar said that he should not himself disregard the just complaints of his allies. [Sidenote: Ariovistus's spirited reply to Caesar.] Ariovistus had no fear of Caesar. Caesar had, in fact, thus far, not begun to acquire the military renown to which he afterward attained Ariovistus had, therefore, no particular cause to dread his power. He sent him back word that he did not understand why Caesar should interfere between him and his conquered province. "The Aeduans," said he, "tried the fortune of war with me, and were overcome; and they must abide the issue. The Romans manage their conquered provinces as they judge proper, without holding themselves accountable to any one. I shall do the same with mine. All that I can say is, that so long as the Aeduans submit peaceably to my authority, and pay their tribute, I shall not molest them; as to your threat that you shall not disregard their complaints, you must know that no one has ever made war upon me but to his own destruction, and, if you wish to see how it will turn out in your case, you may make the experiment whenever you please." [Sidenote: Preparations for war.] Both parties immediately prepared for war. Ariovistus, instead of waiting to be attacked, assembled his army, crossed the Rhine, and advanced into the territories from which Caesar had undertaken to exclude him. [Sidenote: Panic in the Roman army.] As Caesar, however, began to make his arrangements for putting his army in motion to meet his approaching enemy, there began to circulate throughout the camp such extraordinary stories of the terrible strength and courage of the German soldiery as to produce a very general panic. So great, at length, became the anxiety and alarm, that even the officers were wholly dejected and discouraged; and as for the men, they were on the very eve of mutiny. [Sidenote: Caesar's address.]
