Thank you very much R.D. for the lookup.

Shipman Reed was born in Arkansas in August 1848. He must have fudged his age. He would have been 13 not 16 when he enlisted. He did in 1930. So died at age 82.

For the majority of the war, the minimum enlistment age was 18. Boys who wanted to enlist but weren't old enough wrote the number 18 on a scrap of paper and put it their shoes, so when a boy was asked how old he was by the recruiting officer, he could truthfully say I am over eighteen and I stand on my word.
