Throughout September and early October, Charles maintained his pressure on Moreau's army, pushing it further to the west.
On 18 September, part of an Austrian division under Feldmarschall-Leutnant Petrasch swept from Karlsruhe, south to Kehl and stormed the Rhine bridgehead there; he succeeded in holding it, with high losses (about 2,000 of his 5,000 men were killed, wounded or missing).
Immediately, though, General Schauenburg, the French garrison commander, counter-attacked and drove the Austrians back; the French lost 1,200 killed or wounded, and 800 captured.
Even though the French still held the crossing at Kehl and Strasbourg, Petrasch's Austrians prevented Moreau from using the crossing to escape, leaving the bridge at Hüningen as his only reliable route to France.
If Moreau, at that point situated in Freiburg, withdrew too soon from the Breisgau, Pierre Marie Barthélemy Ferino 's column would be trapped there.

The next contact occurred on 19 October at Emmendingen, in the Elz valley which winds through the Black Forest.
The section of the valley involved in the battle runs southwest through the mountains from Elzach, through Bleibach and Waldkirch.
Just to the southwest of Waldkirch, the river emerges from the mountains and flows north-west towards the Rhine, with the Black Forest to its right.
This section of the river passes through Emmendingen before it reaches Riegel.
Riegel sits in a narrow gap between the Black Forest and an isolated outcropping of volcanic hills known as the Kaiserstuhl.
Here the archduke split his force into four columns.

Column Nauendorf, in the upper Elz, had 8 battalions and 14 squadrons, advancing southwest to Waldkirch; column Wartensleben had 12 battalions and 23 squadrons advancing south to capture the Elz bridge at Emmendingen.
Latour, with 6,000 men, was to cross the foothills via Heimbach and Malterdingen, and capture the bridge of Köndringen, between Riegel and Emmendingen, and column Fürstenberg held Kinzingen, about 2 miles (3.2 km) north of Riegel.
Michael Fröhlich and Condé (part of Friedrich Joseph, Count of Nauendorf's column) were to pin down Ferino and the French right wing in the Stieg valley.
Nauendorf's men were able to ambush Saint' Cyr's advance; Latour's columns attacked Beaupuy at Matterdingen, killing the general and throwing his column into confusion.
Wartensleben, in the center, was held up by French riflemen until his third (reserve) detachment arrived to outflank them.
In the ensuing melee, Wartensleben was mortally wounded.
The French retreated across the rivers, destroying all the bridges.

Lack of bridges did not slow the Coalition pursuit.
The Austrians repaired the bridges by Matterdingen, and moved on Moreau at Freiburg.
On 20 October, Moreau's army of 20,000 united south of Freiburg im Breisgau with Ferino's column.
Ferino's force was smaller than Moreau had hoped, bringing the total of the combined French force to about 32,000.
Charles' combined forces of 24,000 closely followed Moreau's rear guard from Freiburg, southwest, to a line of hills stretching between Kandern and the river.
