Unable to deploy in the valley, and confident in the cavalry screen, Alten has taken the risk of moving his corps very close to the enemy still in column of march.
Leval has withdrawn his battle line back to the Vilada road and deployed most of his infantry in line
Rather than deploy in two lines of column further back, Alten has marched his whole corps clear of the valley, and very close to the French, still in column of march. None of them, except the cavalry, can fight in this formation. If the French cavalry had not been routed they would not have dared to take this risk.
