This is identified as being Corporal Hiram Madden, Company F, 5th Michigan Volunteer Infantry Regiment. My problem is that the 5th Michigan Infantry received dark blue 5 button "Michigan" blouses. This plainly is not a dark blue 5 button blouse. This left me a couple of possibilities.
1. The photo has been misidentified.
2. Madden is wearing a pre war militia uniform. The Michigan Uniformed Militia regulations at the start of the Civil War called for gray uniforms/
3. He is wearing the gray uniform with black trim issued to NCOs from the 5th to 7th Michigan at the Camp of Instruction which NCOs of those regiments attended prior to those regiments were formed and before Michigan started making the Michigan 5 button blouses.
I went with opinion #3. However, some people greatly disagree with my view.
