Plutarch, Cicero
Bernadotte Perrin, Ed.

38. But when Caesar set out for Spain, Cicero at once sailed to Pompey.¹ The rest of Pompey's followers were glad to see him, but when Cato saw him, he privately blamed him much for attaching himself to Pompey. In his own case, Cato said, it was not honourable to abandon the line of public policy which he had chosen from the beginning; but Cicero, though he was of more service to his country and his friends if he remained at home without taking sides and accommodated himself to the issue of events, without any reason and under no compulsion had made himself an enemy of Caesar, and had come thither to share in their great danger.

[2] By these words the purpose of Cicero was upset, as well as by the fact that Pompey made no great use of him. But he was himself to blame for this, since he made no denial that he was sorry he had come, made light of Pompey's preparations and showed a lurking displeasure at his plans, and did not refrain from jests and witty remarks about his comrades in arms; nay, although he himself always went about in the camp without a smile and scowling, still he made others laugh in spite of themselves. [3] And it will be well to give a few instances of this also. When Domitius, then, was advancing to a post of command a man who was no soldier, with the remark that he was gentle in his disposition and prudent, ‘Why, then,’ said Cicero, ‘do you not keep him as a guardian of your children?’ [4] And when certain ones were praising Theophanes the Lesbian, who was prefect of engineers in the camp, because he had given excellent consolation to the Rhodians on the loss of their fleet, ‘What a great blessing it is,’ said Cicero, ‘to have a Greek as prefect!’ Again, when Caesar was successful for the most part and in a way was laying siege to them,² Lentulus said he had heard that Caesar's friends were gloomy, to which Cicero replied: ‘You mean that they are ill-disposed to Caesar.’ [5] And when a certain Marcius, who had recently come from Italy, spoke of a report which prevailed in Rome that Pompey was besieged, ‘And then,’ said Cicero, ‘did you sail off that you might see with your own eyes and believe?’ Again, after the defeat, when Nonnius said they ought to have good hopes, since seven eagles were left in the camp of Pompey, ‘Your advice would be good,’ said Cicero, ‘if we were at war with jackdaws.’ [6] And when Labienus, insisting on certain oracles, said that Pompey must prevail, ‘Yes,’ said Cicero, ‘this is the generalship that has now cost us our camp.’
