Pompey had not yet brought on the right wing, but stayed and looked about, waiting to see what execution his cavalry would do on the left. They had already drawn out their squadrons in form, designing to turn Caesar's flank, and force those few horse, which he had placed in the front, to give back upon the battalion of foot.
But Caesar, on the other side, having given the signal, his horse retreated back a little, and gave way to those six subsidiary cohorts, which had been posted in the rear, as a reserve to cover the flank, and which now came out, three thousand men in number, and met the enemy; and when they came up, standing by the horses, struck their javelins upwards, according to their instructions, and hit the horsemen full in their faces. They, unskillful in any manner of fight, and least of all expecting or understanding such a kind as this, had not courage enough to endure the blows upon their faces but turning their backs, and covering their eyes with their hands, shamefully took to flight. Caesar's men, however, did not follow them, but marched upon the foot, and attacked the wing, which the flight of the cavalry had left unprotected, and liable to be turned and taken in the rear, so that this wing now being attacked in the flank by these, and charged in the front by the tenth legion, was not able to abide the charge, or make any longer resistance, especially when they saw themselves surrounded and circumvented in the very way in which they had designed to invest the enemy. Thus these being likewise routed and put to flight, when Pompey, by the dust flying in the air, conjectured the fate of his horse, it were very hard to say what his thoughts or intentions were, but looking like one distracted and beside himself, and without any recollection or reflection that he was Pompey the Great, he retired slowly towards his camp, without speaking a word to any man, exactly according to the description in the verses-"But Jove from heaven struck Ajax with a fear;Ajax the bold then stood astonished there, Flung o'er his back the mighty sevenfold shield, And trembling gazed and spied about the field."In this state and condition he went into his own tent and sat down, speechless still, until some of the enemy fell in together with his men that were flying into the camp, and then he let fall only this one word, "What! into the very camp?" and said no more, but rose up, and putting on a dress suitable to his present fortune, made his way secretly out.
By this time the rest of the army was put to flight, and there was a great slaughter in the camp among the servants and those that guarded the tents, but of the soldiers themselves there were not above six thousand slain, as is stated by Asinius Pollio, who himself fought in this battle on Caesar's side. When Caesar's soldiers had taken the camp, they saw clearly the folly and vanity of the enemy; for all their tents and pavilions were richly set out with garlands of myrtle, embroidered carpets and hangings, and tables laid and covered with goblets. There were large bowls of wine ready, and everything prepared and put in array, in the manner rather of people who had offered sacrifice and were going to celebrate a holiday, than of soldiers who had armed themselves to go out to battle, so possessed with the expectation of success and so full of empty confidence had they gone out that morning.
