A while back, I heard of an archive of photographs at the Military History Institute in Carlisle, PA. The article said they had photos of a great many Union army officers of the Civil War. So I wrote to them, and sure enough, I was able to order a portrait of great-great Grandpa Henry B. Myers.
As you may recall from my posts on his son Stephen, the 33rd Iowa saw combat action in Arkansas and Mississippi, in particular a long bivouac and eventually a major battle at Helena, Ark. Living conditions there were primitive and unsanitary, as documented in this history. Like many of the men stationed at Helena, Henry developed chronic dissentery. He received a medical discharge in March of 1864, while the 33rd was still in the thick of action, and died three months later. Although these old photos can be deceiving, in this one I would say Henry looks a bit hollowed-out.
As for Stephen, no further progress to report. My current thinking is that he was most probably not wounded and left for dead, as his obituary stated, but I am still entertaining the idea that he may have accompanied his father on the military expedition. Stay tuned.
