P. G. T. Beauregard
Miles was selected for both the provisional and regular Confederate Congress. He was chairman of the House Military Affairs Committee while also serving as an aide-de-camp for General P. G. T. Beauregard at both Charleston, in the buildup to the attack on Fort Sumter, and the First Battle of Bull Run. Recognizing, however, his own lack of military training, Miles focused most of his attention on his congressional duties.
