Here is a photo of my grandfather, Allen Lee Millard Gooch. He served in the 89th Division, Military Police company in France. He was inducted on 25 Apr 1918 and discharged 11 Jun 1919. Below is a picture of him on his motorcycle–his job was to paint signs and ride to the front (or close to it) to post them. I don’t know the nature of the signs, but I do have letters he wrote home which describe the bullets whizzing by his head as he was riding back to his unit. I will post some of his letters sometime. They are amazing!
A few pages from his Military Service Record are posted here.
