By this time scouts reported the enemy in some force on the left. Two or three Ohio skirmishers had been killed. Carlisle’s battery was sent to the front of the woods on the right, where it could be brought to play when needed. A few shells were thrown into the opposite thicket, and then the Second Ohio and Second New York marched down to rout the enemy from their hiding places. As they rushed toward a thickly-covered abatis on the banks of the Run, the rebels came swarming out like bees, and fled to the next fortification beyond. General Schenck’s brigade was moved forward to the left, but half way to the Run met the full fire of a masked battery effectually concealed by the bushes. A few dead and wounded began to be brought in, and the battle of Manassas had commenced. Carlisle’s howitzers and the great rifled gun were opened in the direction of the battery, which answered promptly, and a brief but terrific cannonading ensued. In less than half an hour the enemy’s guns were silenced, two of Carlisle’s howitzers advancing through the woods to gain a closer position, and Schenck’s brigade retired to its first lines. At eleven o’clock, the artillery, which resounded from every portion of the field, extending from Davies and Richardson’s position on the extreme left, to the right near Sudley, gave startling evidence that Hunter was making his way around the enemy. The roll and thunder was incessant—great volumes of smoke surged over the vast field, impaling it in the distance, and making the air around the near batteries thick with smoke. It was true, Hunter’s and Heintzelman’s columns had taken the field on the extreme right. McDowell in his plan of battle had calculated that the marching colunm should diverge from the turnpike by early daylight (a night march being deemed imprudent), and reach Sudley Ford by six or seven, A. M. The Stone Bridge division did not clear the road over which both, for a certain distance, had to pass, so that the column could take up its march, until after the time. The route to Sudley proved far longer and more difficult than was anticipated. The column did not reach the Sudley Ford till near half-past nine, three or four hours “behind time.” When it reached the ford, the heads of the enemy’s columns were visible on the march to meet it. The ground between the stream and the road, leading from Sudley south, was for about a mile thickly wooded; on the right, for the same distance, divided between fields and timber. A mile from the ford the country on both sides of the road is open, and for a mile further large, irregular fields extend to the turnpike, which, after crossing Bull Run at the “Stone Bridge,” passes what became the field of battle, through the valley of a small tributary of the Run.
