In the meantime, more and more Austrian troops poured into the west bank of the river. The final brigade of Radivojevich, three squadrons of uhlans, and two brigades of Pflacher's division crossed the Mincio between 9 and 10 am. The Austrian reserve division under General Merville arrived at Pozzolo and halted to await further instructions. But while the situation for the French appeared bleak in the center, their southern offensive proved far more successful. There were about 20,000 men being used for this double-pronged attack and there would be two main assaulting points: the fortress of Mantua, from which Grenier would begin, and the village of Goito, a bit further upstream from Mantua and where Eugène was commanding. The vanguard of Eugène's assault was led by General Bonnemains, who controlled the 31st Chasseurs à Cheval, two light infantry battalions, and four guns. General Mayer's outposts were easily overrun, over 500 became prisoners, and Grenier and Eugène finally linked up at the village of Roverbella. In danger of being outflanked, General Mayer retreated three-and-a-half mile north-eastwards to the village of Mozzecane. The French kept pursuing to the north and thought they would meet the main Austrian force around Villafranca, only to be bitterly disappointed. Around 10 am, Eugène heard gunfire on the western bank of the river and was astonished to see much of the Austrian army at a place where he completely did not expect them.
