My ancestor James T. Lyon was captured July 5, 1864 at the Chattahoochee River. I'm trying to figure out where on the river he was when he was captured.

I found this on a website about the Atlanta Campaign......July 5-17, 1864.
Operations on the line of the Chattahoochee River, with skirmishes at Howell's, Turner's, and Pace's Ferries, Isham's
Ford, and other points.

Anyone know where the 35th was on the 5th?
Thankyou for the help!
