August 5, 1862, :HQ TRANS-MISS DIST, Little Rock, Ark to General S. COOPER from Gen Hindman: “The arms brought out by Captain Hart, together with those brought by General Parsons, have relieved me of embarrassment and enabled me to make effective the greater part of my command.”

I know the story of Parson's bringing an artillery train with him when he corssed back west of the Mississippi, but what arms were "brought out by Captain Hart"? Does this imply that Hart help bring guns from east of the river back to Arkansas?
