Unfortunately, there is not a great deal of information on Benavides' Regiment. They served along the Texas-Mexico border, from Laredo to Brownsville. Most of what I know is from the book Rip Ford's Texas. Another book is Jerry Don Thompson's Vaqueros in Blue and Gray. Also, the Last Battle of the Civil War: Palmetto Ranch, by Jeffrey Wm. Hunt. Some of the companies assigned to Santos Benavides participated in this battle, i.e. Cocke's Company. I cannot even find a roster of Cocke's Company. I am piecing it together, little by little. So far I have come up with about 10 who were members of this company.
