Your local library can borrow a copy from another library through its interlibrary loan department. So far David's book is the only one that gives a good account of the fighting. The burial place(s) of Confederates killed there may be difficult, if not impossible, to find. Bodies left behind when the Confederate forces left the area might have been put in a mass grave by Union soldiers. If the Confederates took any bodies with them, they might have ended up in cemeteries at Jackson or Clinton, Louisiana.
