Milroy, he left no clear direction for Milroy to evacuate, since Milroy had convinced Schenck that his defensive position in Winchester was strong. Milroy had previously decided to disregard concerns from Washington because he was confident that the strength of his fortifications would allow his garrison to withstand an assault or a siege. Rodes' Division advances on Berryville and Martinsburg Ewell, based on good intelligence from sources in the lower Valley, had foreseen that Milroy's only escape route could be successfully blocked and had already anticipated by having Rodes' Division advance on Martinsburg via Berryville to cut off Milroy's expected retreat route, per his plans from 11 June. That afternoon, having reached Berryville, Rodes' Division and Jenkins' cavalry brigade attempted to capture McReynolds' Brigade, but, alerted to the Confederate movement by the firing of signal guns by Milroy's main force in Winchester, McReynolds withdrew to Winchester, where his force occupied the Star Fort north of town. Nevertheless, the Confederates were able to capture portions of the Federal supply train at nearby Bunker Hill, West Virginia, along with 75 prisoners.

Johnson extended his line to the right against very light opposition. There was fitful skirmishing in the streets of Winchester. Early and Ewell conferred on Bower's Hill and decided on a flanking strategy. Gordon's Brigade and two batteries were left on Bower's Hill, while Early led his three other brigades back to Cedar Creek Grade, west beyond Apple Pie Ridge where it was out of view of Federal fortifications, then north over Cloverdale Plantation to Walnut Grove. His column was accompanied by 20 guns. While Early made this march, Johnson advanced a line of skirmishers on the right to occupy the Federals' attention, providing diversionary skirmishing all day from 10 a.m. until about 4 p.m. The Confederate batteries on Bower's Hill opened up, touching off a duel with the Federal guns in Fort Milroy. By mid-afternoon,
