This manual is a copy of US Infantry Tactics.
This work is based on the two volumes in one of the US Infantry tactics that has added explanation and comments from Lt. Col. H Wilson and was printed in Columbus Ohio in 1863. This is an unusual work and scarce.
This copy is complete and has the original bindings. It is tight with wear to the spine. There are no missing pages and the pages have some foxing but quite readable. There is an identification to "John O'Brien 14th Inf I Vol". I am not sure about the Las three letters.
