My great grandfather lied about his age and joined the US cavalry at age 16, he was part general pershing's expeditionary force that chased after pancho villa in 1916-17. I dont think either side was "good" but it definitely is a fascinating period. After that he got sent to France for the first world war where he mostly supported artillery units hauling supplies but was briefly injured during a poison gas attack. He recovered and remained in France until after the end of the war. After a few unsavory episodes apparently he was seriously considering murdering one of his commanding officers and likely deserting but decided against as he had a battlefield conversion experience and decided to give up violence along with his alcoholism and whoring along with other vices he picked up as a cavalry man. He was discharged and returned home. I think he worked in a casket factory or something until the depression. At which time he got a job with a CCC project in colorado building a train trestle bridge. As part of the program he got a tax free property in the mountains of colorado somewhere near tabernash I believe. After the trestle project was done he built a cabin on his property and spent some time hunting and fishing there until he got a job in Englewood colorado where he stayed til he passed away on the early 90s. We still have a lot of his things, his cavalry uniform, spurs, photos, hunting equipment, I have his tools and revolver. For better or worse people seemed to be built different back then. Had fascinating lives.
