I our prior correspondence, you found the following:

One of the prisoners at Ft. Delaware, (Judge) John W. Stevens, Co. K, 5th Texas Infantry, wrote a book in 1902 and said, “No one but my own company men knew him, and we always addressed him as Sam and never as captain. I fed him a stolen ration every night. I had known him from boyhood---a brave and gallant man”.

As you stated, Sam disguised himself as a private prior or during capture so he would have a better chance to escape POW prison.

I have a bio-sketch (that needs to be revised now) of Sam A. Willson along with two post war photos and one pre-war photo. I will see about sending them to you at your e-mail address. Thank you very much.
