No problem! Not sure I've explained how I am selecting individuals. My approach is to first find identified, original, wartime photographs (ambrotypes, cartes de visite or tintypes) of men who served in the Union army. This includes those who served in the USCT, black regiments not designated as USCT (Ex.: Fifty-fourth Massachusetts Infantry), and non-USCT regiments. I also plan to include a few images of men (like Nicholas Biddle) who participated in some capacity before the U.S. government allowed men of color to join the army.

Only after I've located an image that meets my criteria and secured a high-resolution scan of the image do I begin researching the individual.

My goal is to find photos of seventy-seven men. This number is consistent with my other two books.

Hope this answer helps. Finding photographs that meet my criteria has been a challenge. I hope you and others who read this can help.
