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 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
