Hi Bill-
Thanks much. That is the one source I have for information on the battle. It features a picture- engraving, really, of the Union wounded being towed on the bayou. I can't quite pick out poor Pat Duggan but I know he's there. I'll go back to it & see what it contains for sources. I remember being cofused by the maps that seemed at odds with the text but that's too common in CW literature.
Thanks again for your information.
