adherents in Germany.
But still more ruinous for them would be the displeasure of an
irresistible conqueror, who, with a formidable army, was already before
their gates, and who might punish their opposition by the ruin of their
commerce and prosperity. In vain did their deputies plead the danger
which menaced their fairs, their privileges, perhaps their constitution
itself, if, by espousing the party of the Swedes, they were to incur the
Emperor's displeasure. Gustavus Adolphus expressed to them his
astonishment that, when the liberties of Germany and the Protestant
religion were at stake, the citizens of Frankfort should talk of their
annual fairs, and postpone for temporal interests the great cause of
their country and their conscience. He had, he continued, in a menacing
tone, found the keys of every town and fortress, from the Isle of Rugen
to the Maine, and knew also where to find a key to Frankfort; the safety
of Germany, and the freedom of the Protestant Church, were, he assured
them, the sole objects of his invasion; conscious of the justice of his
cause, he was determined not to allow any obstacle to impede his
progress. "The inhabitants of Frankfort, he was well aware, wished to
stretch out only a finger to him, but he must have the whole hand in
order to have something to grasp." At the head of the army, he closely
followed the deputies as they carried back his answer, and in order of
battle awaited, near Saxenhausen, the decision of the council.

If Frankfort hesitated to submit to the Swedes, it was solely from fear
of the Emperor; their own inclinations did not allow them a moment to
doubt between the oppressor of Germany and its protector. The menacing
preparations amidst which Gustavus Adolphus now compelled them to
decide, would lessen the guilt of their revolt in the eyes of the
Emperor, and by an appearance of compulsion justify the step which they
willingly took. The gates were therefore opened to the King of Sweden,
who marched his army through this imperial town in magnificent
procession, and in admirable order. A garrison of 600 men was left in
Saxenhausen; while the king himself advanced the same evening, with the
rest of his army, against the town of Hoechst in Mentz, which
surrendered to him before night.

While Gustavus was thus extending his conquests along the Maine, fortune
crowned also the efforts of his generals and allies in the north of
Germany. Rostock, Wismar, and Doemitz, the only
