Danny,
Due to a problem with my PC did not read your post until today. The records on the 29th are vague. The order of battle for Pryor's command in December,1862 shows the 29th as part of his brigade. Gen. Marshall sent the 29th, 54th, and 50th regiments to the area. I also have the volumes mentioned by Mike and I have the official records on CD-ROM. The OR dates the 29th's assignment to Corse as March, 1863. And by the way , as to bouncing back and forth from Lance to CPL. LOL. One of the best machine gunners to ever serve under me in The Corps never had a stripe on his sleeve in 4 years!! But he could fire single shots with an M-60! No mean feat. He could also practically write his name with the piece.
