The French prepared a great advance on three fronts, with Jourdan and Jean Victor Marie Moreau on the Rhine and the newly promoted Napoleon Bonaparte in Italy. The three armies were to link up in Tyrol and march on Vienna. In the Rhine Campaign of 1796, Jourdan and Moreau crossed the Rhine River and advanced into Germany. Jourdan advanced as far as Amberg in late August while Moreau reached Bavaria and the edge of Tyrol by September. However Jourdan was defeated by Archduke Charles, Duke of Teschen and both armies were forced to retreat back across the Rhine. Napoleon, on the other hand, was successful in a daring invasion of Italy. In the Montenotte Campaign, he separated the armies of Sardinia and Austria, defeating each one in turn, and then forced a peace on Sardinia. Following this, his army captured Milan and started the Siege of Mantua. Bonaparte defeated successive Austrian armies sent against him under Johann Peter Beaulieu, Dagobert Sigmund von Wurmser and József Alvinczi while continuing the siege.
