The centre of the allied army had been utterly routed, before either the Commander-in-Chief at the left, or General Colli at the right of the line, had any notion that a battle was going on.
Such was the battle of Monte Notte, the first of Napoleon's fields.
Beaulieu, in order that he might re-establish his communication with Colli (much endangered by the defeat of D'Argenteau) was obliged to retreat upon Dego; the Sardinian, with the same purpose in view, fell back also, and took post at Millesimo; while D'Argenteau was striving to re-organise his dispirited troops in the difficult country between.

It was their object to keep fast in these positions until succours could come up from Lombardy; but Napoleon had no mind to give them such respite.
The very next day after this victory he commanded a general assault on the Austrian line.

Augereau, with a fresh division, marched at the left upon Millesimo; Massena led the centre towards Dego; and Laharpe, with the French right wing, manoeuvred to turn the left flank of Beaulieu.
Augereau rushed upon the outposts of Millesimo, seized and retained the gorge which defends that place, and cut off Provera with two thousand Austrians, who occupied an eminence called Cossaria, from the main body of Colli's army.

Next morning Buonaparte himself arrived at that scene of the operations.

He forced Colli to accept battle, utterly broke and scattered him, and Provera, thus abandoned, was obliged to yield at discretion.
Meanwhile Massena on the same day had assaulted the heights of Biastro, and carrying them at the point of the bayonet, cut off Beaulieu's communication with Colli; then Laparpe came in front and in flank also upon the village of Dego, and after a most desperate conflict, drove the Austrian commander-in-chief from his post.
