On the north of the National road the First Corps under Hooker had been opposed by one of Hill's brigades and four of Longstreet's, and had gradually worked its way along the old Hagerstown road, crowning the heights in that direction after dark in the evening. Gibbon's brigade had also advanced in the National road, crowding up quite close to Turner's Gap and engaging the enemy in a lively combat. It is not my purpose to give a detailed history of events which did not come under my own eye. It is due to General Burnside, however, to note Hooker's conduct toward his immediate superior and his characteristic efforts to grasp all the glory of the battle at the expense of truth and of honorable dealing with his commander and his comrades. Hooker's official report for the battle of South Mountain was dated at Washington, November 17th, when Burnside was in command of the Army of the Potomac, and when the intrigues of the former to obtain the command for himself were notorious and near their final success. In it he studiously avoided any recognition of orders or directions received from Burnside, and ignores his staff, whilst he assumes that his orders came directly from McClellan and compliments the staff officers of the latter, as if they had been the only means of communication. This was not only insolent but a military offence, had Burnside chosen to prosecute it. He also asserts that the troops on our part of the line had been defeated and were at the turnpike at the base of the mountain in retreat when he went forward. At the close of his report, after declaring that "the forcing of the passage of South Mountain will be classed among the most brilliant and satisfactory achievements of this army," he adds, "its principal glory will be awarded to the First Corps."
