General Birney first learned of the shameful stampede of the German corps by the flight of their troops across his lines; and seeing that retreat was inevitable he prepared for it, but found that the rebels had gained possession of the road by which he had advanced. He was, therefore, obliged to make a road out, which he did by moving quietly down into the ravine. This movement was successfully accomplished with no further trouble than a slight skirmish with the rebels in the ravine; after which General Birney moved his column out in perfect order. General Whipple, with much difficulty, saved his command, which was attacked in rear by the rebels, and broken in upon on the flank by the demoralized men of the Eleventh. He brought off his troops, however, in comparatively good order, and bivouacked for the night with Birney and Pleasanton on a little farm in the woods. Thus ended the battle of the second day. THE THIRD DAY’S BATTLE. SUNDAY, MAY 3. Once more General Hooker formed a new line of battle, which placed General Reynolds on the extreme right, with his right flank resting on the Rappahannock. General Slocum’s corps held the centre, and that of General Sickles the left, with its left resting on the stream called Scott’s creek. Couch and Meade were left to look after the front towards Fredericksburg, while the remnant of the Eleventh was to be used, if it could be reorganized, wherever it could be most effective. On the previous night, during the confusion of the stampede, General Berry, of Sickles’ corps, had moved up the plank road and taken a position just at the edge of the woods, where he met the enemy as they were advancing to complete the discomfiture of the right wing, and had hurled them back most effectually. He was then ordered to retain the ground he had thus defended, which he did most gallantly, and lost his life at the post of duty. Precisely at sunrise the rebels advanced with characteristic promptness and courage, upon the two divisions commanded by General Sickles. At the same moment, another body pushed down the road towards Berry’s division, and fell upon it with great violence. Never, on any battle field, have men of any nation fought with more determined bravery than did the rebel force on this occasion. It was evident that this battle must decide the contest of the campaign between the National and the rebel troops. The opposing force of Union men was very small; but they fought with most determined bravery. Although they were assailed by a force of twenty thousand men, against whom they could oppose only the remains of two brigades under Williams and Whipple, numbering not over five thousand in all, there was no faltering. On the occasion of this Sunday morning attack the colors of the corps were still upon the field, as also the corps commander. Their brigade colors were also there, and he is but a poor soldier who deserts his flag when it is in danger, and there was danger now.
