This Henry County AL link should help --

However, I believe this line to be incorrect --

It was assigned to the 25th Regiment Georgia Infantry on May 2, 1862.

The company had already been assigned to the 25th Georgia. When reorganized under the Conscript Act on May 2, 1862, the company was assigned to the 38th Georgia.

Since both the 38th and 60th Georgia served together in Lawton's-Gordon's Georgia Brigade, campaigns, battles and skirmishes will be the same for both regiments. Of course once the company was reassigned to the 61st Alabama in April 1864, you should follow campaigns, battles and skirmishes for Battle's Alabama Brigade.
