One morning, on the Enipeus, near Larissa, the 9th of August, old style, or toward the end of May by real time, Caesar had broken up his camp and was preparing for his usual leisurely march, when he perceived a movement in Pompey's lines which told him that the moment which he had so long expected was come. Labienus, the evil genius of the Senate, who had tempted them into the war by telling them that his comrades were as disaffected as himself, and had fired Caesar's soldiers into intensified fierceness by his barbarities at Durazzo, had spoken the deciding word: "Believe not," Labienus had said, "that this is the army which defeated the Gauls and the Germans. I was in those battles, and what I say I know. That army has disappeared. Part fell in action; part perished of fever in the autumn in Italy. Many went home. Many were left behind unable to move. The men you see before you are levies newly drawn from the colonies beyond the Po. Of the veterans that were left, the best were killed at Durazzo." A council of war had been held at dawn. There had been a solemn taking of oaths again. Labienus swore that he would not return to the camp except as a conqueror; so swore Pompey; so swore Lentulus, Scipio, Domitius; so swore all the rest. They had reason for their high spirits. Pompey had forty-seven thousand Roman infantry, not including his allies, and seven thousand cavalry. Caesar had but twenty-two thousand, and of horse only a thousand. Pompey's position was carefully chosen. His right wing was covered by the Enipeus, the opposite bank of which was steep and wooded. His left spread out into the open plain of Pharsalia. His plan of battle was to send forward his cavalry outside over the open ground, with clouds of archers and slingers, to scatter Caesar's horse, and then to wheel round and envelop his legions. Thus he had thought they would lose heart and scatter at the first shock. Caesar had foreseen what Pompey would attempt to do. His own scanty cavalry, mostly Gauls and Germans, would, he well knew, be unequal to the weight which would be thrown on them. He had trained an equal number of picked active men to fight in their ranks, and had thus doubled their strength. Fearing that this might be not enough, he had taken another precaution. The usual Roman formation in battle was in triple line. Caesar had formed a fourth line of cohorts specially selected to engage the cavalry; and on them, he said, in giving them their instructions, the result of the action would probably depend.
