My great-grandfather Henry Harrison Staub was also a member of the 132nd Ohio Infantry. I found some history of this unit at: http://www.infinet.com/~lstevens/a/cw132.html They were mustered in at Camp Chase, Ohio, on May 14-15, 1864 as an Ohio national guard unit, did guard duty at the White House around May and June. Had picket duty at the Bermuda Hundred with the Army of the James (Henry Harrison Staub described laying in the swampy mud for hours at a time here, resulting in lots of sick soldiers) Mustered out September 10, 1864.
