That day, Suvorov got definite news of MacDonald's offensive. Meanwhile, a French squadron put in at Genoa on 2 June to drop off French reinforcements. Intelligence indicated that Moreau was about to descend from the mountains. Suvorov ordered Bellegarde's corps to march on Alessandria to keep an eye on Moreau while the rest of his army concentrated against MacDonald. The "Army of Naples" negotiated the Apennine Mountains in four major columns. The divisions of Montrichard and Jean-Baptiste Dominique Rusca formed the eastern-most column, moving from Florence to Bologna. Next to the west were the divisions of Jean-Baptiste Olivier and François Watrin, accompanied by MacDonald and advancing from Pistoia on Modena. Farther west was Jean Henri Dombrowski's division descending the Secchia River valley. The western-most column was made up of Victor's division marching from Borgo Val di Taro down the Taro River toward Parma. Because MacDonald's offensive across the Apennines was so unlikely, it took the Austrian covering forces by surprise. These were Klenau's command southwest of Ferrara, now reduced to 3,500 men, Prince Friedrich Franz Xaver of Hohenzollern-Hechingen at Modena with 4,800 troops and Ott west of Fornovo di Taro. MacDonald planned to destroy Hohenzollern's division by pinning it with his own column while enveloping it with Dombrowski's division from the west and Rusca's division from the east. Klenau deduced the French strategy and shifted northeast behind the Panaro River to block Rusca. MacDonald lost touch with Dombrowski's command. Nevertheless, MacDonald fell on the Austrians at Modena with two divisions. On 12 June in the Battle of Modena, the French inflicted losses of 750 killed and wounded on their enemies while capturing 1,650 men, eight guns and three colors. French casualties were 400 killed and wounded and 200 captured. During the pursuit, MacDonald was set upon by a troop of French Royalist cavalry and suffered saber cuts on the head and arm before his own soldiers could finish off their enemies. Since the fortress of Alessandria commanded the only crossing of the Bormida, the Austro-Russian main body waited on a pontoon train which finally arrived on 15 June. At 5:00 pm the span was in place and Suvorov's army crossed and marched all night to reach Castelnuovo Scrivia on the morning of the 16th.
