Unhappy with Hiller's inability to chase Eugène out of Italy, the Hofkriegsrat replaced him with Count Heinrich von Bellegarde. When Joachim Murat defected to the Coalition in January 1814, bringing the army of the Kingdom of Naples with him, Eugène abandoned the line of the Adige and fell back to the Mincio River. Hoping to secure a bridgehead across the Mincio, Bellegarde put his army in motion. On the same day, Eugène determined to drive back the Austrian outposts. These actions brought about the Battle of the Mincio River on 8 February 1814. The Franco-Italians won the battle while losing 3,000 killed and wounded and 500 captured out of 34,000 troops engaged. The Austrians suffered losses of 2,800 killed and wounded plus 1,200 men captured. Accompanied by Bellegarde, Radivojevich's right-wing got across the Mincio at Borghetto near Valeggio and began to drive back Eugène's weak left wing under Jean-Antoine Verdier. Meanwhile, Eugène made his main effort on the right with Paul Grenier's reinforced corps. He and Grenier crossed the river and began rolling up the Austrian left wing after heavy fighting near Pozzolo. Though outnumbered three-to-one, Verdier's men proved unexpectedly tenacious and held out most of the day. When Eugène and Grenier approached Valeggio from the south, threatening to cut them off from the east bank, Bellegarde and Radivojevich hastily withdrew their soldiers and conceded defeat. Undaunted, they tried to force a crossing two days later but were repulsed again. Discouraged, Bellegarde never again tried to break the Mincio line during the campaign.
