Does anyone know of good primary source accounts from the French army for the 1807 invasion of Portugal, subsequent occupation, and then the campaign leading up to Vimeiro? So far I have Thiébault's narrative and memoirs, Foy's history, and two accounts from artillery officers (the brothers Hulot). I also have several French histories of the campaign. What I could really do with are memoirs or letters from the infantry and cavalry. Does anyone know of any?
