The details of a Roman campaign are no longer interesting. The results, with an outline of the means by which they were brought about, alone concern the modern reader. Pompey's lieutenant, having failed to secure the passes, was lying at Lerida, in Catalonia, at the junction of the Segre and the Naguera, with the Ebro behind them, and with a mountain range, the Sierra de Llena, on their right flank. Their position was impregnable to direct attack. From their rear they drew inexhaustible supplies. The country in front had been laid waste to the Pyrenees, and everything which Caesar required had to be brought to him from Gaul. In forty days from the time at which the armies came in sight of each other Afranius and Petreius, with all their legions, were prisoners. Varro, in the south, was begging for peace, and all Spain lay at Caesar's feet. At one moment he was almost lost. The melting of the snows in the mountains brought a flood down the Segre. The bridges were carried away, the fords were impassable, and his convoys were at the mercy of the enemy. News flew to Rome that all was over, that Caesar's army was starving, that he was cut off between the rivers, and in a few days must surrender. Marseilles still held out. Pompey's, it seemed, was to be the winning side, and Cicero and many others, who had hung back to watch how events would turn, made haste to join their friends in Greece before their going had lost show of credit.[2] The situation was indeed most critical. Even Caesar's own soldiers became unsteady. He remarks that in civil wars generally men show less composure than in ordinary campaigns. But resource in difficulties is the distinction of great generals. He had observed in Britain that the coast fishermen used boats made out of frames of wicker covered with skins. The river banks were fringed with willows. There were hides in abundance on the carcasses of the animals in the camp. Swiftly in these vessels the swollen waters of the Segre were crossed; the convoys were rescued. The broken bridges were repaired. The communications of the Pompeians were threatened in turn, and they tried to fall back over the Ebro; but they left their position only to be intercepted, and after a few feeble struggles laid down their arms. Among the prisoners were found several of the young nobles who had been released at Corfinium. It appeared that they regarded Caesar as an outlaw with whom obligations were not binding. The Pompeian generals had ordered any of Caesar's soldiers who fell into their hands to be murdered. He was not provoked into retaliation. He again dismissed the whole of the captive force, officers and men, contenting himself with this time exacting a promise from them that they would not serve against him again. They gave their word and broke it. The generals and military tribunes made their way to Greece to Pompey. Of the rest, some enlisted in Caesar's legions; others scattered to combine again when opportunity allowed.
