ing the war into
the heart of Austria. As the Austrian dominions in that quarter were
entirely defenceless, Wallenstein received immediate orders to leave the
King of Denmark, and if possible to intercept Mansfeld's progress
through Silesia.

The diversion which this movement of Mansfeld had made in the plans of
Wallenstein, enabled the king to detach a part of his force into
Westphalia, to seize the bishoprics of Munster and Osnaburg. To check
this movement, Tilly suddenly moved from the Weser; but the operations
of Duke Christian, who threatened the territories of the League with an
inroad in the direction of Hesse, and to remove thither the seat of war,
recalled him as rapidly from Westphalia. In order to keep open his
communication with these provinces, and to prevent the junction of the
enemy with the Landgrave of Hesse, Tilly hastily seized all the tenable
posts on the Werha and Fulda, and took up a strong position in Minden,
at the foot of the Hessian Mountains, and at the confluence of these
rivers with the Weser. He soon made himself master of Goettingen, the

towards Brunswick. But Tilly incessantly harassed his retreat, and
after three days' skirmishing, he was at length obliged to await the
enemy near the village of Lutter in Barenberg. The Danes began the
attack with great bravery, and thrice did their intrepid monarch lead
them in person against the enemy; but at length the superior numbers and
discipline of the Imperialists prevailed, and the general of the League
obtained a complete victory. The Danes lost sixty standards, and their
whole artillery, baggage, and ammunition. Several officers of
distinction and about 4,000 men were killed in the field of battle; and
several companies of foot, in the flight, who had thrown themselves into
the town-house of Lutter, laid down their arms and surrendered to the
conqueror.

The king fled with his cavalry, and soo
