The Battle of Limburg or Second Battle of Altenkirchen or Battle of the Lahn (16–19 September 1796) saw a Habsburg Austrian army commanded by Archduke Charles, Duke of Teschen attack a Republican French army led by Jean Baptiste Jourdan in its positions behind the Lahn River. The unexpected collapse of their right flank on the evening of the 16th compelled the French to make a three-day fighting withdrawal. The action occurred during the War of the First Coalition, part of a wider conflict known as the Wars of the French Revolution. Limburg an der Lahn is located in the state of Hesse in Germany about 50 kilometres (31 mi) east of Koblenz.
