Banks, hearing of Ewell's arrival in the Valley, fears an attack from him and Jackson combined, and retires from Harrisonburg to New Market.
Jackson's inaction for some weeks, and now his movement to West Virginia, reassures the Federal Administration, and Shields, with more than half of Banks' force, is detached at New Market, and ordered to Fredericksburg to swell McDowell's corps to over 40,000 men.
McDowell says his corps at this time consisted of the divisions of McCall, King and Ord. * * * There were about 30,000 men altogether.
Then General Shields came with about 11,000 men, making my force about 41,000 men.
He had also 100 pieces of artillery.
See McDowell's testimony before the Committee on Conduct of the War, part I, 1863, page 267. Banks is left with only some 7,000 or 8,000, and falls back to Strasburg, which he fortifies.
Shields left New Market May 12th. He assumes a defensive attitude, to hold the lower Valley, and to cover the Baltimore and Ohio railroad
