he analogy of the relation subsisting between the praetor
and the consul or the consul and the dictator served generally
as a basis, so that, while the governor in his own right retained
the supreme military authority in his province, the Imperator
was entitled at any moment to take it away from him and assume it
for himself or his delegates, and, while the authority of the governor
was confined to the province, that of the Imperator, like the regal
and the earlier consular authority, extended over the whole empire.
Moreover it is extremely probable that now the nomination
of the officers, both the military tribunes and the centurions,
so far as it had hitherto belonged to the governor,(36) as well as
the nomination of the new adjutants of the legion, passed directly
into the hands of the Imperator; and in like manner even now
the arrangement of the levies, the bestowal of leave of absence,
and the more important criminal cases, may have been submitted
to the judgment of the commander-in-chief. With this limitation
of the powers of the governors and with the regulated control
of the Imperator, there was no great room to apprehend
in future either that the armies might be utterly disorganized
or that they might be converted into retainers personally devoted
to their respective officers.

Caesar's Military Plans
Defence of the Frontier

But, however decidedly and urgently the circumstances pointed
to military monarchy, and however distinctly Caesar took the supreme
command exclusively for himself, he was nevertheless not at all
inclined to establish his authority by means of, and on, the army.
No doubt he deemed a standing army necessary for his state,
but only because from its geographical position it required
a comprehensive regulation of the frontiers and permanent frontier
garrisons. Partly at earlier periods, partly during the recent
civil war, he had worked at the tranquillizing of Spain,
and had established strong positions for the defence of the frontier
in Africa along the great desert, and in the north-west of the empire
along the line of the Rhine. He occupied himself with similar plans
for the regions on the Euphrates and on the Danube. Above all
he designed an expedition against the Parthians, to avenge the day
of Carrhae; he had destined three years for this war, and was resolved
to settle accounts with these dangerous enemies once for all
and not less cautiously than thoroughly. In like manner
he
