This was an interesting bit of trivia I didn't know about. In 1944, 2nd Lt. Jackie Robinson -- yes, that Jackie Robinson -- was court-martialed after refusing to move to the back of a bus on a Texas army base. The army had recently desegregated army buses on army bases, and so Robinson knew he was entirely in the right when he refused to move back. Nonetheless, he was taken into custody and interrogated by a superior officer who was none too keen on the "uppity" Robinson.
Robinson was charged with insubordination, but in part thanks to excellent representation and in part thanks to sterling testimony by his battalion commander, he was acquitted of all charges.
