On the banks of Cedar Run, seven miles south of Culpeper and but one or two north of the mountain, Banks's cavalry were waiting to oppose Jackson's advance. Learning of this the latter halted and waited for an attack.

General Pope had made glowing promises of certain success and he well knew that the whole North was eagerly watching and waiting for him to fulfil them. He must strike somewhere and do it soon — and here was his chance at Cedar Mountain. He sent Banks with nearly eight thousand men against this brilliant Southern commander with an army three times as large, holding a strong position on a mountain side.

Banks with his infantry left Culpeper Court House on the morning of August 9th and reached the Confederate stronghold in the afternoon. He approached the mountain through open fields in full range of the Confederate cannon, which presently opened with the roar of thunder. All heedless of danger the brave men ran up the slope as if to take the foe by storm, when suddenly they met a brigade of Ewell's division face to face and a brief, deadly encounter took place.
