Using the Island of Lobau as a spring board, can you take Lannes Corps and deliver the decisive blow to the Austrian army? Alternatively lead Massénas corps to glory, or succeed with the massed cuirassier divisions of Bessières against the infantry of Hohenzollern. The Austrians will need commanders with their wits about them, to assault and take the fortified Granary in Essling and defeat Massénas troops in Aspern. The game is afoot, can Napoleon win through, or can the Austrians complete the first defeat over the monster of Europe!
