Julius Caesar wrote The Civil War for the same reason he wrote about his campaigns in Gaul – i.e. to prove to the Roman people that his cause was just and that his opponents were unjust. The work was never completed, and the reason for this may be conjectured as having won the civil war – against the Pompeian faction – Caesar no longer needed to defend his actions because he was in full control of the state.
“…but let me remind you it is always at the end of a war that soldiers look for the reward of their efforts, and what that end is going to be not even you can doubt.
“Is it conceivable that a side which could make no stand with all its forces intact can now do so when its cause is lost; and can you, who declared for Caesar when victory still hung in the balance, now think of siding with the vanquished, after the issue of the war is decided, and when you ought to be reaping the reward of your services?
“With what seems to be a tradition among foreign nations, the African force lay scattered about their camping-ground without any properly made lines; consequently, when our troopers dashed in upon the broken groups of heavily sleeping men, numbers were slaughtered on the spot, and a considerable body took refuge in panic-stricken flight.
“But Curio answered unhesitatingly that, having lost the army which Caesar had entrusted to his charge, he would never go back to look him in the face, and with that answer he died fighting. Only a very small proportion of the Roman cavalry escaped from the battle; but those who, as recorded above, had dropped behind in the rear for the purpose of resting their horses, on observing from their distant position that the whole army was a rout, made good their return to the camp. The infantry were all cut down to a man.
“Inside the Pompeian lines the eye fell upon the spectacle of arbors artificially constructed, of masses of silver plate laid out for present use, of tents paved with cool, fresh cut sods, and even, in the case of Lentulus and others, protected from the heat by ivy. Many other indications could likewise be discerned of extravagant luxury and of confidence in coming victory, rendering it an easy assumption that men who went so far out of their way in the pursuit of superfluous pleasures could have had no misgivings as to the issue of the day. Yet these were the men who habitually taunted the poverty-stricken, long-suffering army of Caesar with the charge of being voluptuaries; whereas in truth they had all along been in want of the barest necessaries.
