I have three original photos (CDV albumen print format) of officers of the 1st Missouri (Bissell's) Engineers of the Civil War era. They are identified, but I do not know if they were from Company E as I have not researched their records. I can provide their names if you are interested. Either the Missouri State Archives (archref@mail.sos.state.mo.us) or the national archives has microfilm of the roster cards for this regiment. You might start with the Missouri Archives first as they respond quickly and are very customer friendly. The national archives is much slower to respond and is not as professional. Dale West
