Whatever might be the feeling in the latter country, there was no doubt as to the popularity of Maximilian's cause in Austria. Great enthusiasm prevailed, and his advance was as rapid and bloodless as it was triumphant. Vienna University declared unanimously in his favour, and, by the end of June, 12,000 men had enlisted in his service. In July Maximilian entered Graz, and on August 19, made his triumphal entry into Vienna, which had been hastily abandoned by the Hungarian forces.[32] The oath of allegiance was taken to Maximilian only: the citizens remembered Frederick too well to entrust themselves a second time to his mismanagement. Meanwhile Uladislas had been proclaimed King of Hungary on July 15, 1490,[33] and in September was crowned at Stuhlweissenburg. Maximilian on this occasion displayed great activity, and, aided by a liberal grant of money from the Tyrolese Estates, invaded Hungary at the head of an army of about 17,000 men. Crossing the Raab late in October, he met with but slight opposition; Uladislas was unprepared, and by nature averse to energetic measures; and the invader was joined by a number {30} of Hungarian magnates. But this phenomenal success was fatal to the invaders; and by the time that it reached Stuhlweissenburg, the army was virtually out of hand. In spite of a firm resistance, the city was cannonaded (Maximilian personally directing the artillery) and taken by storm; but a disgraceful scene of plunder and slaughter ensued. Maximilian and his captains were quite unable to restrain the soldiers, and on the next day an open mutiny broke out. Their refusal to advance upon Buda, and the consequent delay, proved fatal to the whole enterprise. When summoned to surrender, the capital indignantly declined, and Uladislas found time to bring up his Bohemians and to threaten Vienna. Frederick III., true to his ultra-Fabian motto--"Mit der Zeit lohnt oder rächt sich alles"[34]--sent no assistance, and Maximilian, seeing his base endangered, and hampered by want of money and discipline, found it necessary to withdraw westwards. His overtures to Poland met with no response, and he was quite unable to continue the struggle alone. By July 1491 Stuhlweissenburg fell into the hands of Uladislas, and all Maximilian's recent conquests were lost. The urgent appeals of Reichenburg to Maximilian for reinforcements and of Maximilian to his father for money were all in vain. His position was absolutely desperate from sheer want of funds,[35] while the turn which Breton affairs were taking seemed to render peace necessary, at whatever price. Frederick, who {31} throughout the war had thwarted his aims and damped his ardour,[36] now offered his mediation, and negotiations were opened in August. By the Treaty of Pressburg (November 7, 1491), Uladislas was formally recognized as King of Hungary, but, failing his lawful issue, the crown was to fall to Maximilian or his son. This
