Just found this online…
It’s a Google eBook of CAMERONE – The French Foreign Legion’s Greatest Battle, by James W. Ryan, a thin hardcover (110 pages, including index) published in 1996.
The entire book is not uploaded, as I believe it is meant only to be sampled prior to purchase.
Have to say, if you’re interested in Camerone and don’t have a copy, IMHO you should!
The eBook is not cheap — looks like it goes for almost $80.00.
The book and eBook includes several simple maps/diagrams of the battlefield and the hacienda compound.
I bought my copy from Articles of War, back in 1998, for about $50.00.
