At the Battle of Cedar Mountain, undeterred by a storm of artillery fire, Stonewall Jackson directed his men into a mile-long battle line stretching from the trees on one side to the shelf of Cedar Mountain on the other, and placed his cannons near the Crittenden Gate, in a grove of cedar trees south of present-day Route 15, and on the shelf of Cedar Mountain. Confederate gunners soon hurled shot and shell at Federal artillery across the field, and the duel raged for more than two hours as men squeezed through the crowded Crittenden Gate and incoming shells burst among the Southern infantry, forcing some off the road and through the trees to reach their positions. Union Gen. Nathaniel P. Banks had only 8,000 men against Jackson's force of more than 17,000, but many Confederates had not yet arrived when Banks ordered an attack. As the artillery fire lifted about 5 P.M., the Ohioans, Pennsylvanians, New Yorkers, and Marylanders of Gen. Christopher C. Augur's division advanced to strike the center of the Confederate line. During the fighting, Gen. Charles S. Winder was struck by a shell that tore through his side and arm, and Jackson sought to attack Banks while he was isolated from the rest of Pope's army, but Banks, by launching his own attack, isolated himself further.
