R.W. Johnson wrote to General A.S. Johnston on 18 November 1861 and among other issues, discussed Bocage's resignation:

One other subject I beg to call to your attention: I understood that the Arkansas regiment formerly Colonel Hindman is greatly discontented. It is because of the action of General Hardee placing a stranger from another State over them, and the regiment protests. I learn the facts from Lieutenant-Colonel Bocage, who has resigned. I will not go into the many particulars he relates, embracing the protest of all the officers of the regiment, but will merely say that it is a course pursued towards the troops of no other State, and would be submitted to by no other State quietly. The State of Arkansas has no fame to bank upon that she can see her opportunities sacrificed to the personal preferences of General Hardee, and we all know that honor won by the Missourian, the commanding officer, would inure to Missouri, if not also reflect upon Arkansas, that she had no man fit, in the opinion of the commanding officer, to lead them. I have protested to the Government against this course, and had wished to lay the matter personally before you, but find I cannot.
