had
obtained a free passage for his troops through Treves.

Pending these negociations with Treves and France, the king's generals
had entirely cleared the territory of Mentz of the Spanish garrisons,
and Gustavus himself completed the conquest of this district by the
capture of Kreutznach. To protect these conquests, the chancellor
Oxenstiern was left with a division of the army upon the Middle Rhine,
while the main body, under the king himself, began its march against the
enemy in Franconia.

The possession of this circle had, in the mean time, been disputed with
variable success, between Count Tilly and the Swedish General Horn, whom
Gustavus had left there with 8,000 men; and the Bishopric of Bamberg, in
particular, was at once the prize and the scene of their struggle.
Called away to the Rhine by his other projects, the king had left to his
general the chastisement of the bishop, whose perfidy had excited his
indignation, and the activity of Horn justified the choice. In a short
time, he subdued the greater part of the bishopric; and the capital
itself, abandoned by its imperial garrison, was carried by storm. The
banished bishop urgently demanded assistance from the Elector of
Bavaria, who was at length persuaded to put an end to Tilly's
inactivity. Fully empowered by his master's order to restore the bishop
to his possessions, this general collected his troops, who were
scattered over the Upper Palatinate, and with an army of 20,000 men
advanced upon Bamberg. Firmly resolved to maintain his conquest even
against this overwhelming force, Horn awaited the enemy within the walls
of Bamberg; but was obliged to yield to the vanguard of Tilly what he
had thought to be able to dispute with his whole army. A panic which
suddenly seized his troops, and which no presence of mind of their
general could check, opened the gates to the enemy, and it was with
difficulty that the troops, baggage, and artillery, were saved. The
reconquest of Bamberg was the fruit of this victory; but Tilly, with all
his activity, was unable to overtake the Swedish general, who retired in
good order behind the Maine. The king's appearance in Franconia, and
his junction with Gustavus Horn at Kitzingen, put a stop to Tilly's
conquests, and compelled him to provide for his own safety by a rapid
retreat.

The king made a general review of his troops at Aschaffenburg. After
his junction with Gustavus Horn, Banner, and Duke William of Weimar,
