1809
1809 saw the War of the Fifth Coalition, as the British and Austrians united to take on the French. Whilst the British were tied up in the Peninsular campaign, the Austrians attempted to retake territory they had previously held in Germany. This led to Napoleon leaving Spain and heading east to take charge himself, resulting in several major battles in Aspern-Essling and Wagram among others. This latter was a crushing defeat for Austria and resulted in the Treaty of Schönbrunn, ending the Fifth Coalition.
