Information of the catastrophe was promptly communicated to General Sickles, who thus had a moment given him to prepare for the shock he instantly apprehended his column would suffer. The high land of the little farm that formed the base of his operations was parked full of artillery and cavalry, nearly all the artillery of the Third corps, together with Pleasanton’s cavalry, being crowded into that little fifty-acre inclosure. But Sickles was not to be thrown off his guard by a trifle, and anything short of a complete defeat seemed to be considered by him in the light of a trifle. With the coolness and skillfulness of a veteran of a hundred campaigns he set to work making his dispositions. He had not a single regiment within his reach to support his artillery; Whipple was falling back, and must meet the approaching stampede with his own force in retreat; Birney was far out in the advance, in imminent danger of being completely surrounded and annihilated; the rebel forces were pressing hard upon the flying Germans, who could only escape by rushing across his lines, with every prospect of communicating the panic to them. It was a critical moment indeed, and one that might well stagger even the bravest-hearted. But it did not stagger the citizen soldier. Calling to the members of his staff, he sent them all off, one after the other, lest any one should fail of getting through, to warn Birney of his danger and order him to fall back. Then, turning to General Pleasanton, he directed him to take charge of the artillery, and train it upon all the woods encircling the field, and support it with his cavalry, to hold the rebels in check should they come on him, and himself dashed off to meet Whipple, then just emerging from the woods in the bottom land. He had scarcely turned his horse about when the men of Howard’s corps came flying over the field in crowds, meeting the head of Whipple’s column, and stampeding through its lines, running as only men do run when convinced that sure destruction is awaiting them. At the same moment large masses of the rebel infantry came dashing through the woods on the north and west close up to the field, and opened a tremendous fire of musketry into the confused mass of men and animals. To add to the confusion and terror of the occasion, night was rapidly approaching, and darkness was already beginning to obscure the scene.
