retire. He considered it, however, as equivalent to a victory, to have
disturbed the repose of the enemy in their winter quarters, who, by the
severity of the weather, sustained a loss of 3000 horses. He now made a
movement towards the Oder, as if with the view of reinforcing himself
with the garrisons of Pomerania and Silesia; but, with the rapidity of
lightning, he again appeared upon the Bohemian frontier, penetrated
through that kingdom, and relieved Olmutz in Moravia, which was hard
pressed by the Imperialists. His camp at Dobitschau, two miles from
Olmutz, commanded the whole of Moravia, on which he levied heavy
contributions, and carried his ravages almost to the gates of Vienna.
In vain did the Emperor attempt to arm the Hungarian nobility in defence
of this province; they appealed to their privileges, and refused to
serve beyond the limits of their own country. Thus, the time that
should have been spent in active resistance, was lost in fruitless
negociation, and the entire province was abandoned to the ravages of the
Swedes.

While Torstensohn, by his marches and his victories, astonished friend
and foe, the armies of the allies had not been inactive in other parts
of the empire. The troops of Hesse, under Count Eberstein, and those of
Weimar, under Mareschal de Guebriant, had fallen into the Electorate of
Cologne, in order to take up their winter quarters there. To get rid of
these troublesome guests, the Elector called to his assistance the
imperial general Hatzfeldt, and assembled his own troops under General
Lamboy. The latter was attacked by the allies in January, 1642, and in
a decisive action near Kempen, defeated, with the loss of about 2000 men
killed, and about twice as many prisoners. This important victory
opened to them the whole Electorate and neighbouring territories, so
that the allies were not only enabled to maintain their winter quarters
there, but drew from the country large supplies of men and horses.
