At this point, the French government belatedly transferred two divisions commanded by Jacques MacDonald and Jean Castelbert de Castelverd from France's idle Army of the North. MacDonald's division stopped at Düsseldorf while Castelverd's was placed in the French line on the lower Lahn. These reinforcements brought Jourdan's strength up to 50,000, which would have given him an edge on Charles, except that his abandonment of the sieges at Mainz, and later Mannheim and Philippsburg, released 16,200 and 11,630 Habsburg troops (respectively) to reinforce Charles' already overwhelming numbers. Moreau seemed oblivious to Jourdan's situation. Still far to the east of Jourdan, Moreau crossed to the south bank of the Danube on 19 August, leaving only Antoine Guillaume Delmas's division on the north bank. By no later than the 20th, Moreau was aware that Charles had recrossed the Danube, heading north, but instead of pursuing him, the French general pressed eastward toward the river Lech. Ferino's right wing, which had been wandering with seeming aimlessness around upper Swabia and Bavaria, finally rejoined the Army of Rhine and Moselle on 22 August, although Delaborde's division remained well to the south. Ferino's only notable action was repulsing a night attack by the 5,000–6,000-man Army of Condé at Kammlach on 13–14 August. The French Royalists and their mercenaries sustained 720 casualties, while Ferino lost a number of prisoners. In this action, Captain Maximilien Sébastien Foy led a Republican horse artillery battery with distinction. Facing the southern-most wing of the Army of the Rhine and Moselle, the combative Latour rashly stood to fight on the Lech near Augsburg on 24 August. Despite rising waters in which some soldiers drowned, Saint-Cyr and Ferino attacked across the river. In the Battle of Friedberg the French crushed an Austrian infantry regiment, inflicting losses of 600 killed and wounded plus 1,200 men and 17 field guns captured. French casualties numbered 400. Over the next few days, Jourdan's army withdrew again to the west bank of the Rhine. After his disastrous panic at Diez, Castelverd held east bank entrenchments at Neuwied and Poncet crossed at Bonn while the other divisions retired behind the Sieg.
