On 14 June 1800, the French army under Napoleon Bonaparte was taken by surprise and attacked by the Austrian army under General Melas. Outnumbered and outgunned, the French were defeated and forced to retreat. But later that same day, French reinforcements arrived under General Desaix, and in what amounted to a second battle the French counter-attacked and won, taking thousands of prisoners and driving the Austrians from the field.
Thus was won the battle of which Napoleon was always the most proud – Marengo.
Bonaparte at Marengo recreates that dramatic battle. The game is simple and fast-playing, departing from almost all of the standard conventions of wargaming in order to achieve the look and feel of nineteenth century linear warfare.
