I wrote a regimental history on the 38th Mississippi and will be happy to help you - the 38th did indeed have a very strong connection with the 17th Illinois - in fact, a number of men from the 38th deserted after the siege of Vicksburg ended and joined the 17th Illinois. If you would like to contact me directly, I will be happy to help you. My e-mail address is: championhilz@comcast.net
