The night was freezing cold. The hard ground shrouded in mist. By dawn the soldiers were on the move. It was 2 December 1805 and just outside what is now Brno, 3 mighty armies were about to fight one of the greatest battles in history. By the time the sun set, the French Emperor Napoleon Bonaparte had achieved a stunning victory, a victory so decisive that it would set the course of European history for a decade. It was the Battle of Austerlitz.
