Many thanks, so it seems Bonnet and Lerida is what Pétiet intended.

Even though we found out elsewhere that there was no officer Bonnet with the 1er léger, but another one named Bouché, and that the 1er léger had not been at Lerida.

Was it at Tarragona ?

Maybe through personal contacts the editor of the 1844 edition knew better than Pétiet, and corrected Bonnet and Lerida to Bouché and Tarragone.

Maybe ...
