Mike,
Thank you, that was a good read. My Great Grandfather was on the recieving end (90th Illinois) of Swetts battery at Missionary Ridge. It is my understanding that Captain Swett was not there at the time but his guns were. It was nice to hear from him how they moved a section of his battery and replaced the section with four howitzers. I think that was when the Corporal that at that point was in command with Lt. Key. I could be wrong but that is my memory of the day. Frank
