Mechanicsville (Beaver Dam Creek) and inexplicably ordered his men to bivouac for the night within clear earshot of the battle. He was late and disoriented at Gaines's Mill. He was late again at Savage's Station. The upcoming action in support of Lee's assault at Glendale would offer him another opportunity. Jackson and Lee met privately on the morning of June 30 at Savage's Station and Lee's exact orders were not recorded, but they apparently were for Jackson to march to White Oak Swamp and engage the Union forces there to prevent them from reinforcing the remainder of the rear guard at Glendale. The last Union unit to travel south through White Oak Swamp, and thus Jackson's target, was the VI Corps under Brig. Gen. William B. Franklin, consisting of the divisions of Brig. Gens. William F.
