Sometimes called the Battle of Limburg or Second Battle of Altenkirchen or Battle of the Lahn (16–19 September 1796), this was actually a single-day battle followed by a lengthy rear-guard action. On 16 September, the Habsburg Austrian army commanded by Archduke Charles, Duke of Teschen attacked a Republican French army led by Jean-Baptiste Jourdan in its positions behind the Lahn River. The unexpected collapse and withdrawal of their right flank on the evening of the 16th compelled the French to make a fighting withdrawal that began in the evening of the 16th and continued until late on 19 September.
