August 1863 Michael Gassmann enlisted
8th Iowa Volunteer Cavalry.
Excerpt from a letter written by Sgt.
Washington Tharp that stated:
“..that I was a sergeant in Company G,
8th Iowa Cavalry; that I was well acquainted with Michael Gassmann of the
same company and Regiment; that we were both captured on the
thirtieth day of July 1864 about 30 miles southeast of Atlanta and
taken from there to Andersonville Georgia; that whilst at
Andersonville said Gassmann contracted the chronic diarrhea and was
very low all the time whilst in that prison…from Andersonville we
were both removed to Florence, South Carolina. Gassmann was hardly
able whilst at this…place to get around”. Michael’s name has now
been added to the National Park Service records at Andersonville.
