Amazing details!
Do you by any chance know of any Situational de troupes reports for the 3rd Corps prior to April 19th? I have seen SHDT data from this website https://officiersdenapoleon.jimdo.com/la-péninsule-ibérique/la-albuera/ but I am not aware of any way to look at these reports online. I have Mr. John Gill books on the 1809 campaign and I am reading through Saski work, but my real passion is looking closely at the men who fought the battles. I have been collecting uniform and portraits of many of the men who fought at this combat.
Thank you for your help again!
