and Protestant bishops were present,
either personally or by deputy, at this assembly, which the chaplain to
the Saxon Court, Dr. Hoe von Hohenegg, opened with a vehement discourse
from the pulpit. The Emperor had, in vain, endeavoured to prevent this
self-appointed convention, whose object was evidently to provide for its
own defence, and which the presence of the Swedes in the empire,
rendered more than usually alarming. Emboldened by the progress of
Gustavus Adolphus, the assembled princes asserted their rights, and
after a session of two months broke up, with adopting a resolution which
placed the Emperor in no slight embarrassment. Its import was to demand
of the Emperor, in a general address, the revocation of the Edict of
Restitution, the withdrawal of his troops from their capitals and
fortresses, the suspension of all existing proceedings, and the
abolition of abuses; and, in the mean time, to raise an army of 40,000
men, to enable them to redress their own grievances, if the Emperor
should still refuse satisfaction.

A further incident contributed not a little to increase the firmness of
the Protestant princes. The King of Sweden had, at last, overcome the
scruples which had deterred him from a closer alliance with France, and,
on the 13th January 1631, concluded a formal treaty with this crown.
After a serious dispute respecting the treatment of the Roman Catholic
princes of the empire, whom France took under her protection, and
against whom Gustavus claimed the right of retaliation, and after some
less important differences with regard to the title of majesty, which
the pride of France was loth to concede to the King of Sweden, Richelieu
yielded the second, and Gustavus Adolphus the first point, and the
treaty was signed at Beerwald in Neumark. The contracting parties
mutually covenanted to defend each other with a military force, to
protect their common friends, to restore to their dominions the deposed
princes of the empire, and to replace every thing, both on the frontier
and in the interior of Germany, on the same footing on which it stood
before the commencement of the war. For this end, Sweden engaged to
maintain an army of 30,000 men in Germany, and France agreed to furnish
the Swedes with an annual subsidy of 400,000 dollars. If the arms of
Gustavus were successful, he was to respect the Roman Catholic religion
and the constitution of the empire in all the conquered places, and to
make no attempt aga
