Moravia, and contented himself with securing a key to these provinces,
by leaving behind him Swedish garrisons in the conquered fortresses. He
then directed his march into Bohemia, whither he was followed by the
Imperialists, under the Archduke Leopold. Such of the lost places as
had not been retaken by the latter, were recovered, after his departure,
by the Austrian General Bucheim; so that, in the course of the following
year, the Austrian frontier was again cleared of the enemy, and Vienna
escaped with mere alarm. In Bohemia and Silesia too, the Swedes
maintained themselves only with a very variable fortune; they traversed
both countries, without being able to hold their ground in either. But
if the designs of Torstensohn were not crowned with all the success
which they were promised at the commencement, they were, nevertheless,
productive of the most important consequences to the Swedish party.
Denmark had been compelled to a peace, Saxony to a truce. The Emperor,
in the deliberations for a peace, offered greater concessions; France
became more manageable; and Sweden itself bolder and more confident in
its bearing towards these two crowns. Having thus nobly performed his
duty, the author of these advantages retired, adorned with laurels, into
the tranquillity of private life, and endeavoured to restore his
shattered health.

By the retreat of Torstensohn, the Emperor was relieved from all fears
of an irruption on the side of Bohemia. But a new danger soon
threatened the Austrian frontier from Suabia and Bavaria. Turenne, who
had separated from Conde, and taken the direction of Suabia, had, in the
year 1645, been totally defeated by Mercy, near Mergentheim; and the
victorious Bavarians, under their brave leader, poured into Hesse. But
the Duke of Enghien hastened with considerable succours from Alsace,
Koenigsmark from Moravia, and the Hessians from the Rhine, to recruit
the defeated army, and the Bavarians were in turn compelled to retire to
the extreme limits of Suabia. Here they posted themselves at the
village of Allersheim, near Nordlingen, in order to cover the Bavarian
frontier. But no obstacle could check the impetuosity of the Duke of
Enghien. In person, he led on his troops against the enemy's
entrenchments, and a battle took place, which the heroic resistance of
the Bavarians rendered most obstinate and bloody; till at last the death
of the great Mercy, the skill of Turenne, and the iron firmness of the
