exclusion of the imperial armies from their
territories, and from supplies either of men, provisions, or ammunition.
Hard as the conditions were, which the victor thus imposed upon the
vanquished, the French mediator flattered himself he should be able to
induce the Elector of Bavaria to accept them. In order to give time for
an accommodation, Gustavus had agreed to a cessation of hostilities for
a fortnight. But at the very time when this monarch was receiving from
the French agents repeated assurances of the favourable progress of the
negociation, an intercepted letter from the Elector to Pappenheim, the
imperial general in Westphalia, revealed the perfidy of that prince, as
having no other object in view by the whole negociation, than to gain
time for his measures of defence. Far from intending to fetter his
military operations by a truce with Sweden, the artful prince hastened
his preparations, and employed the leisure which his enemy afforded him,
in making the most active dispositions for resistance. The negociation

Bavarians and the Swedes.
Tilly's augmented force, with which he threatened to overrun Franconia,

the Spaniards within his territories, he was still less disposed to
commit his estates to the suspicious protection of a heretic, and to
make the Swedish conqueror master of his destinies. Too weak to
maintain his independence between two such powerful competitors, he took
refuge in the protection of France. With his usual prudence, Richelieu
profited by the embarrassments of this prince to augment the power of
France, and to gain for her an important ally on the German frontier. A
numerous French army was despatched to protect the territory of Treves,
and a French garrison was received into Ehrenbreitstein. But the object
which had moved the Elector to this bold step was not completely gained,
for the offended pride of Gustavus Adolphus was not appeased till he
