Should circumstances now unforeseen make the enterprise too hazardous, abandon it. Your own judgment must decide if risks do or do not counterbalance the important results to be hoped for from success. Brigadier-General Chalmers's move to Memphis and Charleston Railroad should precede yours by a day if practicable. Brigadier-General Jackson was instructed, three or four months ago, to issue the cavalry-arms for which I had applied to the Ordnance Department, so as to convert the best-instructed regiments into cavalry first. Let those instructions be executed. Brigadier-General Jackson is under the misapprehension that you have countermanded them.
