 Modern attempts to deal with his naval service are similarly confounded; notably, Texas Ranger handbooks and sites claim various things, that he graduated from the United States Naval Academy at Annapolis, Maryland, in 1844, and after a year's service resigned from the navy, or that he served as a midshipman, but not at the Academy.The Academy was founded in 1845.The most credible report has him being a midshipman 1844–1846, graduating with the first class ever to graduate from there, Class of 1846, and resigning to fight in the Mexican–American War with the "Texas Rangers," then the military arm of the new State of Texas.
