In the Battle of the Pyrenees in late July 1813, Taupin's division fought in Clausel's corps and suffered 131 killed, 1,045 wounded and 26 captured. His division was not engaged in the Battle of Roncesvalles on 25 July. In the Battle of Sorauren on 28 July, Taupin's whole division launched an assault on the hill of Oricain with Lecamus' brigade on the right and Béchaud's brigade on the left. Normally light companies were used to skirmish. Since Taupin employed his grenadier companies also, the French skirmish line was twice as strong as usual. Lecamus' brigade was repulsed before it reached the crest, but Béchaud's troops briefly established themselves on the crest before being driven off.
