On 13 October 1793, a 43,185-man Coalition army led by Dagobert Sigmund von Wurmser defeated Carlenc's 34,400-strong army in the First Battle of Wissembourg. The government ordered Carlenc's arrest on the 23rd. The "Army of the Rhine" withdrew to the Zorn River near Strasbourg while Wurmser's army occupied northern Alsace. On 22 October, Delauney sent six battalions to Saverne where they helped repel an attack by one of Wurmser's divisions. Pichegru took command of the "Army of the Rhine" on 29 October. That same day Delaunay was dismissed from command of the "Army of the Moselle". The representatives on mission wanted Eustache Charles d'Aoust to replace Delauney but Lazare Hoche arrived from Paris to take command on 31 October. His rank was general of division rather than army commander because he was supposed to act under the orders of Pichegru. On 18 November, Pichegru began a series of attacks on Wurmser's defensive lines in the Battle of Haguenau.
