Military and Financial Results of the Seizure of Italy
But it may be questioned whether Caesar gained or lost more by the conquest of Italy. In a military respect, no doubt, very considerable resources were now not merely withdrawn from his opponents, but rendered available for himself; even in the spring of 705 his army embraced, in consequence of the levies en masse instituted everywhere, a considerable number of legions of recruits in addition to the nine old ones But on the other hand it now became necessary not merely to leave behind a considerable garrison in Italy, but also to take measures against the closing of the transmarine traffic contemplated by his opponents who commanded the sea, and against the famine with which the capital was consequently threatened; whereby Caesar's already sufficiently complicated military task was complicated further still.
Financially it was certainly of importance, that Caesar had the good fortune to obtain possession of the stock of money in the capital; but the principal sources of income and particularly the revenues from the east were withal in the hands of the enemy, and, in consequence of the greatly increased demands for the army and the new obligation to provide for the starving population of the capital, the considerable sums which were found quickly melted away. Caesar soon found himself compelled to appeal to private credit, and, as it seemed that he could not possibly gain any long respite by this means, extensive confiscations were generally anticipated as the only remaining expedient.
