I'm trying to find Masséna's report of May 7, 1811 concerning the battle of Fuentes de Oñoro. I've consulted Koch and Fririon and others, but have been unable to locate the original text. I'd be grateful if anyone can help me find it.
Regards, Terry Doherty
Belmas, vol. I, pp. 533-542, brings probably the report you are looking for:
