On the 26th of September, its deployment beyond the mountains was complete, and as Napoleon did not know of Mack's intention to stay at Ulm and had learned that the Russian advance had been delayed, he directed his columns by the following roads on the Danube, between Donauworth and Ingolstadt, so as to be in a position to intervene between the Austrians and the Russians and beat both in detail.
This was the signal for a general coalition against Turkey; Venice, Poland and the pope allied themselves with the Austrians; Russia, Tuscany and Malta joined in the attack.
One after another the Hungarian forts were captured by the Austrians; the Venetians were equally successful in Greece and the Morea; the Russians pressed on the Crimea, and Sobieski besieged Kamenets.
But the disorder in the army and the administration continued, and the advance of the Austrians and the Venetians met with little opposition.
At first eminently successful, he drove the Austrians across the Danube, recapturing Nish, Vidin, Semendria and Belgrade; repulses were also inflicted on the Venetians and the Russians.
