The movement of the March revolution within the member states of the German Confederation led to the election of Frankfurt Assembly, the first all-German parliament.
On 17 June, August Willich and his irregulars (Freischar) moved from Frankweiler to join Schimmelpfenning at Rinnthal.
The volunteers had barricaded the road between Wilgartswiesen and Rinnthal in order to stop the advance of the Prussian troops towards Landau at a narrow point in the valley.
The fusiliers captured the bridge in front of Rinnthal and then occupied the hill of Buchholzer Berg, which had also not been held in sufficient strength by the volunteers.
On 18 July, the scattered troops then withdrew, together with the main body of the Palatine rebel army, over the bridge at Knielingen to Baden - Willich's Freikorps being the last unit to cross on 19 June.
