Meanwhile, Ignaz Gyulai began his maneuver, leaving General-major Johann Kleinmayer's grenadier reserve to help defend the left flank. Reaching Roveredo around noon, he veered to the southwest, launching three infantry brigades at Eugène's thinned-out center about 1:30 pm. With General-major Anton Gajoli's brigade holding Grenier's division near Ronche, the IX Armeekorps threatened to overwhelm Broussier. Grenier rapidly disengaged most of his troops and sent them back to defend Fontanafredda, while Broussier counterattacked near Vignovo. In the center, there was bitter fighting near Ronche as the French repelled one attack only to have the Austrian mount a second one. Eugène refused to commit Sahuc's cavalry in the face of the Austrian superiority in cavalry. During this crisis, Seras lost Porcia to an Austrian attack.
