Because of the Tyrolese revolt, the viceroy sent General of Division Achille Fontanelli's Italian division to Trento on the upper Adige with General of Division Louis Baraguey d'Hilliers in overall command. By 14 April, Eugène massed six divisions near Sacile with Lamarque's infantry and General of Division Charles Randon de Pully's dragoons still distant. At this time, the Italian Guard, Durutte's infantry, and General of Division Emmanuel Grouchy's dragoons were still assembling on the Adige. Before the war, Eugène proposed to Napoleon that his infantry be formed into three corps, but the emperor had not replied to this request. Because of this, Eugène army fought the coming battle as a collection of divisions, which had a detrimental effect on command control. Meanwhile, John used small forces to mask the fortresses of Osoppo on the upper Tagliamento and Palmanova south of Udine.

Thanks to his scouts, Archduke John had a clear picture of his opponent's army. He ordered Frimont's advance guard to attack the French soldiers at Pordenone in the morning.
