surrendered; but Marienberg he was obliged to carry by storm. In this
place, which was believed to be impregnable, the enemy had collected a
large store of provisions and ammunition, all of which fell into the
hands of the Swedes. The king found a valuable prize in the library of
the Jesuits, which he sent to Upsal, while his soldiers found a still
more agreeable one in the prelate's well-filled cellars; his treasures
the bishop had in good time removed. The whole bishopric followed the
example of the capital, and submitted to the Swedes. The king compelled
all the bishop's subjects to swear allegiance to himself; and, in the
absence of the lawful sovereign, appointed a regency, one half of whose
members were Protestants. In every Roman Catholic town which Gustavus
took, he opened the churches to the Protestant people, but without
retaliating on the Papists the cruelties which they had practised on the
former. On such only as sword in hand refused to submit, were the
fearful rights of war enforced; and for the occasional acts of violence
committed by a few of the more lawless soldiers, in the blind rage of
the first attack, their humane leader is not justly responsible. Those
who were peaceably disposed, or defenceless, were treated with mildness.
It was a sacred principle of Gustavus to spare the blood of his enemies,
as well as that of his own troops.

On the first news of the Swedish irruption, the Bishop of Wurtzburg,
without regarding the treaty which he had entered into with the King of
Sweden, had earnestly pressed the general of the League to hasten to the
assistance of the bishopric. That defeated commander had, in the mean
time, collected on the Weser the shattered remnant of his army,
reinforced himself from the garrisons of Lower Saxony, and effected a
junction in Hesse with Altringer and Fugger, who commanded under him.
Again at the head of a considerable force, Tilly burned with impatience
to wipe out the stain of his first defeat by a splendid victory. From
his camp at Fulda, whither he had marched with his army, he earnestly
requested permission from the Duke of Bavaria to give battle to Gustavus
Adolphus. But, in the event of Tilly's defeat, the League had no second
army to fall back upon, and Maximilian was too cautious to risk again
the fate of his party on a single battle. With tears in his eyes, Tilly
read the commands of his superior, which compelled him to inactivity.
Thus his march to Franco
