Spain was the next campaign for Verdier, and in March 1808 he took command of the 2nd Division of Bessières' corps. After winning at Logrono in June, he was chosen to replace Savary as commander of Aragon and Navarre. Upon taking charge of the siege of Saragossa, Verdier was wounded and then later lifted the siege. In November he was to join Soult's corps, but instead was directed to command the province of Bilbao. Replacing Reille as commander of a German division, Verdier then took up the siege of Girona in March 1809, and in December he accepted the city's surrender. The month before returning to France in April 1810, Verdier distinguished himself in the fighting around Arenys de Mar.
