Brian:
ome of my ancestors served in the 4th cavalry. That knowledge excited my interest a nd I went to Edward Gerdes page and by noting the locations where they suffered casualties was able to make a map of their travels. I was amazed at the territory they covered.... sometimes in a short interval.
One of my ancestors left the 4th Cavalry and transfered to the 34th Inf. That was the reverse of the usual prodedure.
Just a passsing comment.
