but the prelude to the still more crying enormities which shortly
followed.

The secret how Wallenstein had purposed to fulfil his extravagant
designs was now manifest. He had learned the lesson from Count
Mansfeld; but the scholar surpassed his master. On the principle that
war must support war, Mansfeld and the Duke of Brunswick had subsisted
their troops by contributions levied indiscriminately on friend and
enemy; but this predatory life was attended with all the inconvenience
and insecurity which accompany robbery. Like a fugitive banditti, they
were obliged to steal through exasperated and vigilant enemies; to roam
from one end of Germany to another; to watch their opportunity with
anxiety; and to abandon the most fertile territories whenever they were
defended by a superior army. If Mansfeld and Duke Christian had done
such great things in the face of these difficulties, what might not be
expected if the obstacles were removed; when the army raised was
numerous enough to overawe in itself the most powerful states of the
empire; when the name of the Emperor insured impunity to every outrage;
and when, under the highest authority, and at the head of an
overwhelming force, the same system of warfare was pursued, which these
two adventurers had hitherto adopted at their own risk, and with only an
untrained multitude?

Wallenstein had all this in view when he made his bold offer to the
Emperor, which now seemed extravagant to no one. The more his army was
augmented, the less cause was there to fear for its subsistence, because
it could irresistibly bear down upon the refractory states; the more
violent its outrages, the more probable was impunity. Towards hostile
states it had the plea of right; towards the favourably disposed it
could allege necessity. The inequality, too, with which it dealt out
