Johann Ludwig von Erlach (1595 – 1650)
The first Battle of Rheinfelden took place on 28 February 1638, during the Thirty Years' War. On one side of the field was the Bernese Johann Ludwig von Erlach, the Chief of Staff to Duke Bernard of Saxe-Weimar and organiser of the High Rhine campaign, which ended with the cession of Alsace to France. Johann Ludwig von Erlach ended his career as Marshal of France, and is regarded as one of the greatest generals in the mercenary service of the 17th century.
