Thank you. It sounds as though he was a major ringleader, or at least desired the benefits by leading an illegal enterprise. He might not have had an opportunity to enlist at the beginning of the war on the Union side. That clearly is a good reason if he wanted to fight, to head south.Johnson was accused of trying to misappropriate government property during the Mexican War and allowed to resign. A 2008 article in the Murphreesboro Post stated "He was then transferred to Gen. Winfield Scotts army for the Vera Cruz campaign. Instead of being given a combat role, Johnson was appointed acting assistant commissary. At this point in his career, Johnson made a serious mistake in judgment and approached his commanding officer in New Orleans with a scheme to make money by misappropriating government property. That officer turned him in. A government inquiry followed and the decision was appealed to then President James K. Polk. Johnson was allowed to resign his commission in October 1847 without prosecution."
