Here he remained until the spring of 1852, and was in the graduating class of that year, when he took offense at some remark made to him by Stonewall Jackson (then Professor Jackson), in the lecture room, and a passage of sharp words took place between the two. Cadet Walker, feeling that he had been publicly insulted and wronged by Professor Jackson, sent him a challenge to fight a duel.
