Ah yes, the lure of America - of the West. The chance for adventure and freedom. That's what a lot of soldiers who joined the Regular Army after the Civil War were thinking. They were disappointed later when they were assigned to garrison the frontier. Cavalry soldiers deserted more frequently than infantry soldiers because they had horses and could get away faster and go farther. The desertion rate was tremendous and caused a lot of meetings back in DC. They weren't as worried about losing men as they were about losing horses and equipment. Posts tried improving food and paying more, and that helped a bit, but the bottom line was that post duty was mind-numbingly boring. Indians didn't try and attack large posts, such as Fort Lincoln, so there wasn't much in the way of military action unless the men were out on a campaign or a foray of some sort. Many of the soldiers were illiterate and received permission at larger posts (which had officers, their wives and children) to attend school if only to have something to occupy their minds. Scurvy set in because of the limited diet of beef and bread, essentially. This led to budgeting for seeds and creating the post garden, often 10-20 acres or more, which was tended by one or several soldiers specifically assigned to it. Before the invention of the post garden one garrison commander ordered those with scurvy to head out into the prairie and eat their fill of wild onions. It helped cure scurvy but some were killed by Indians while they were munching away. What a life! Private Shea from England was just one of many men who lived like this and was ultimately killed at the Battle of Little Bighorn.
