enemies,
his Austrian territories invaded by a powerful army, the people
hailing the King of the Romans as their deliverer, and the adversary,
whom he had despised and insulted, in the very heart of his dominions.
In these circumstances he recalled his army from Teppel, and led them
through the woods and mountains of Bohemia to Drosendorf, on the
frontiers of Austria, with the hope of saving the capital. But his
troops being harassed by the fatigues of this long and difficult
march, and distressed for want of provisions, he was unable to
continue his progress, while Rudolph, advancing along the southern
bank of the Danube, made himself master of Klosterneuburg by
stratagem, and encamped under the walls of Vienna. Here, being joined
by Meinhard of Tyrol, who had overrun Styria and Carinthia, and drawn
the natives to his standard, he laid siege to the city. The garrison
and people, who were warmly attached to Ottocar and encouraged with
the hopes of speedy relief, held out for five weeks; at length the
want of provisions and the threats of Rudolph to destroy the vineyards
excited a small tumult among the people, and the governor proposed a
capitulation.

During this time the discontents in Ottocar's army increased with
their increasing distress; he was threatened by the approach of the
Hungarians toward the Austrian frontiers; he saw his own troops
alarmed, dispirited, and mutinous; and he was aware that on the
surrender of the capital Rudolph had prepared a bridge of boats to
cross the Danube and carry the war into Bohemia. In this situation,
surrounded by enemies, embarrassed by increasing difficulties,
deserted or opposed by his nobles, his haughty spirit was compelled to
bend; he sued for peace, and the conditions were arranged by the
arbitration of the Bishop of Olmuetz, the Elector Palatine, and the
Burgrave of Nuremberg. It was agreed, on the 22d of November, 1276,
that the sentence of excommunication and deprivation which had been
pronounced against Ottocar and his adherents should be revoked; that
he should renounce all his claims to Austria, Styria, Carinthia,
Carniola, and Windischmark; that he should take the oath of
allegiance, do homage for the remainder of his territories to the head
of the empire, and should receive the investiture of Bohemia, Moravia,
and his other fiefs. An article was also inserted, by which Ottocar
promised to deliver up to Ladislaus, King of Hungary, all the places
wrested from him
