One could logically presume that the 1st Battalion (a battalion is a group of companies - or in the case of Artillery, group of batteries) would have Battery "A" included and that he would have served at Prospect Hill. Logic does not always work in Battalion assignments so other research might be in order. I have also included his record from civilwardata.com which indicates he was in Battery A. You may want to send for his service and pension records at NARA. Hope this helps some. Mike 5th REGIMENT HEAVY ARTILLERY (204th VOLUNTEERS). Organized at Pittsburg August and September, 1864.
