During the afternoon Sickles's brigade took the place of Caldwell's, which had come up to Couch's aid and had suffered severely.
Meagher advanced about 5 o'clocand left, if circumstances should require it. At an early hour in the day Sumner kindly sent me Caldwell's brigade, as he thought I might need help.
This brigade I placed near Butterfield, who was dithis impression.
Batteries of Hunt's Artillery Reserve were sent to him when needed — and also Caldwell's brigade, voluntarily sent to me early in the day by Sumner, and Sickles's brigade, borrowed od Cooke's cavalry engaged with us at Gaines's Mill, nor of Couch's division and the brigades of Caldwell, Meagher, and Sickles serving with it at Malvern.
