On 26 December 1793, Lazare Hoche, in overall command of his own "Army of the Moselle" and Jean-Charles Pichegru's "Army of the Rhine" defeated the Coalition army of Dagobert Sigmund von Wurmser in the Second Battle of Wissembourg. Though part of the Prussian army of Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel intervened late in the day, it could only keep the French from launching a close pursuit. Three days later, Wurmser's army crossed to the east bank of the Rhine River at Philippsburg. The two French armies pressed north along the west bank of the Rhine and relieved the siege of Landau. Brunswick's Prussians withdrew all the way to Worms and Oppenheim.
