lines of communication with Mantua and Vienna, in the belief that this would cause Melas to raise the siege of Genoa. He entered Milan on 2 June and by crossing to the South bank of the Po completely cut Melas's communications. Taking up a strong defensive position at Stradella, he confidently awaited an attempt by the Austrian Army to fight its way out. However, Melas had not raised the siege of Genoa, and on 4 June the French Army marched out with all equipment towards France as per the terms of the negotiated evacuation of the city. Napoleon then faced the possibility that, thanks to the British command of the Mediterranean, far from falling back, the Austrians could instead take Genoa as their new base and be supplied by sea. His defensive posture would not prevent this; he had to find and attack the Austrians before they could regroup. He therefore advanced from Stradella towards Alessandria, where Melas was, apparently doing nothing. Convinced that Melas was about to retreat, Napoleon sent strong detachments to block Melas's routes northwards to the Po, and southwards to Genoa. At this point, Melas attacked, and for all the brilliance of the previous campaign, Napoleon found himself at a significant disadvantage in the consequent Battle of Marengo (14 June). Napoleon was effectively defeated in a tough battle in the morning and early afternoon; Melas, thinking he had already won, had turned over delivery of the coup de grace to a subordinate, when the prompt return of a detached French force under Desaix and a vigorous French counter-attack (in the course of which Desaix was killed) converted the battle into an important French victory. Melas promptly entered into negotiations which led to the Austrians evacuating northern Italy west of the Ticino, and suspending military operations in Italy. Napoleon returned to Paris after the victory, leaving Brune to consolidate in Italy and begin a march toward Austria. Germany Although the First Coalition forces achieved several initial victories at Verdun, Kaiserslautern, Neerwinden, Mainz, Amberg and Würzburg, the efforts of Napoleon Bonaparte in northern Italy pushed Austrian forces back and resulted in the negotiation of the Peace of Leoben (17 April 1797) and the subsequent Treaty of Campo Formio (October 1797). This treaty proved difficult to implement. Austria was slow to give up some of the Venetian territories. A Congress convened at Rastatt for the purposes of deciding which
