Governor Letcher went at once to the War Department to plead with Secretary Benjamin for the saving of Stonewall Jackson's genius and devotion to the Confederate cause. Benjamin so far yielded as to hold open the question of Jackson's resignation. He had not intended to provoke that. It is doubtful that he would have dared it. He had not intended anything, indeed, except to impress his own authority upon the army. When he understood how great a loss Jackson would be to the cause, and how narrowly his own grossly irregular interference with Jackson had missed compelling the resignations of Beauregard, Johnston, and a host of others in high and low position, Mr. Benjamin became placative in an extreme degree. In the meanwhile he had sacrificed all that Jackson's energy and genius had accomplished in the Valley and had discouraged the army in a degree and to an extent for which no later efficiency could by any possibility atone. Until Benjamin interfered with him Jackson was master of the Valley, and of all that its possession signified, by virtue of his painful endeavors to achieve that highly desirable result by means of arduous campaigns in snow and sleet and slush and mud. If he had been let alone Jackson would have been in undisputed command of the upper Potomac country; he would have had Maryland and southern Pennsylvania thenceforth always at his mercy; and with reinforcements that might at any moment have been sent to him he would have been in position to threaten Washington in a way possibly to compel the instant withdrawal of McClellan's army from Richmond and the recall of McDowell's from Fredericksburg. As it was, it was left to Lee to achieve those purposes in much more arduous ways and at cost of great and otherwise needless battles, involving the loss of human lives by tens of thousands, where but for ignorant interference no considerable loss at all would have been necessary. Let us make this matter clear. If Jackson had been let alone in the Valley, of which he had made himself complete master, his way would have been easily open to the region in rear of Washington. With the opening of the spring of 1862 practically the whole of Johnston's army, then still at Manassas and Centreville, together with the troops at Richmond reinforced from the seaboard and the South, could have been pushed by the valley route into Maryland, threatening Washington, Baltimore, Philadelphia and the North. If that had been done McClellan would not have been permitted by his government to advance up the Peninsula. His entire force would have been held at Washington or sent northward and westward to meet the Confederate advance. It would have been Washington, the Federal capital, and not Richmond, the seat of Confederate government, that was besieged.
