The next major action was the Battle of Tarvis from 15 to 18 May. The engagement included two actions where small garrisons of Grenz infantry heroically defended two blockhouses against overwhelming Franco-Italian forces. This was followed by an Austrian disaster at the Battle of Sankt Michael on 25 May. Eugène pursued John into Hungary where he defeated him at the Battle of Raab on 14 June before joining Napoleon at the Battle of Wagram on 5 and 6 July. The last action of note in the theater was the Battle of Graz from 24 to 26 June.
