The First Battle of Kernstown was fought on March 23, 1862, in Frederick County and Winchester, Virginia, the opening battle of Confederate Maj. Gen. Thomas J. "Stonewall" Jackson's campaign through the Shenandoah Valley during the American Civil War.

Attempting to tie down the Union forces in the Valley, under the overall command of Maj. Gen. Nathaniel P. Banks, Jackson received incorrect intelligence that a small detachment under Col. Nathan Kimball was vulnerable, but it was in fact a full infantry division more than twice the size of Jackson's force. His initial cavalry attack was forced back and he immediately reinforced it with a small infantry brigade. With his other two brigades, Jackson sought to envelop the Union right by way of Sandy Ridge. But Col. Erastus B. Tyler's brigade countered this movement, and, when Kimball's brigade moved to his assistance, the Confederates were driven from the field. There was no effective Union pursuit.

Although the battle was a Confederate tactical defeat, and in fact Jackson's only defeat in the war, it represented a strategic victory for the South by preventing the Union from transferring forces from the Shenandoah Valley to reinforce the Peninsula Campaign against the Confederate capital, Richmond. Kernstown started Jackson on the road to being one of the most celebrated Confederate generals.

Jackson's division had been withdrawing "up" the Valley (to the higher elevations at the southwest end of the Valley) to cover the flank of Gen. Joseph E. Johnston's army, withdrawing from the Centreville–Manassas area to protect Richmond. Without this protective movement, the Federal army under Banks might strike at Johnston through passes in the Blue Ridge Mountains. By March 12, 1862, Banks occupied Winchester just after Jackson had withdrawn from the town, marching at a leisurely pace 42 miles up the Valley Pike to Mount Jackson. On March 21, Jackson received word that Banks was splitting his force, with two divisions (under Brig. Gens. John Sedgwick and Alpheus S. Williams) returning to the immediate vicinity of Washington, D.C., freeing up other Union troops to participate in Maj. Gen. George B. McClellan's Peninsula Campaign against Richmond. The remaining division, under Brig. Gen. James Shields, was stationed at Strasburg to guard the lower (northeastern) Valley, and intelligence indicated that it was withdrawing toward Winchester. Banks made preparations to leave the Valley personally on March 23.

Jackson's orders from Johnston were to prevent Banks's force from leaving the Valley, which it appeared they were now doing. Jackson turned his men around and, in one of the more grueling forced marches of the war, moved northeast 25 miles on March 22 and another 15 to Kernstown on the morning of March 23. His cavalry, under Col. Turner Ashby, skirmished with the Federals on March 22, during which engagement Shields was wounded with a broken arm from an artillery shell fragment. Despite his injury, Shields sent part of his division south of Winchester and one brigade marching to the north, seemingly abandoning the area, but in fact halting nearby to remain in reserve. He then turned over tactical command of his division to Col. Nathan Kimball, although throughout the battle to come, he sent numerous messages and orders to Kimball. Confederate loyalists in Winchester mistakenly informed Turner Ashby that Shields had left only four regiments and a few guns (about 3,000 men) and that these remaining troops had orders to march for Harpers Ferry in the morning. Ashby, who normally had a reputation as a reliable cavalry scout, inexplicably did not verify the civilian reports and passed them on to Jackson. Jackson marched aggressively north with his 3,000-man division, reduced from its peak as stragglers fell out of the column, unaware that he was soon to be attacking almost 9,000 men.

Actions at the First Battle of Kernstown, 11 a.m. to 4:45 p.m.

Jackson moved north from Woodstock and arrived before the Union position at Kernstown around 11 a.m., Sunday, March 23. The devoutly religious Jackson preferred to avoid battles on the Sabbath, but throughout his Civil War career he did not hesitate when military advantage could be gained. He later wrote to his wife:

I felt it my duty to [attack], in consideration of the ruinous effects that might result from postponing the battle until the morning. So far as I can see, my course was a wise one; the best that I could do under the circumstances, though very distasteful to my feelings; I hope and pray to our Heavenly Father that I may never again be circumstanced as on that day. I believe that so far as our troops were concerned, necessity and mercy both called for the battle. Arms is a profession that, if its principles are adhered to for success, requires an officer to do what he fears may be wrong ... if success is to be obtained.

Jackson performed no personal reconnaissance before he sent Turner Ashby on a feint against Kimball's position on the Valley Turnpike while his main force—the brigades of Col. Samuel Fulkerson and Brig. Gen. Richard B. Garnett (the Stonewall Brigade, Jackson's own first command)—attacked the Union artillery position on Pritchard Hill. The lead brigade under Fulkerson was repulsed, so Jackson decided to move around the Union right flank, about 2 miles west on Sandy Ridge, which appeared to be unoccupied. If this were successful, his men could move down the spine of the ridge and get into the Union rear, blocking their escape route to Winchester. Kimball countered the maneuver by moving his brigade under Col. Erastus B. Tyler to the west, but Fulkerson's men reached a stone wall facing a clearing on the ridge before the Union men could. Jackson's aide, Sandie Pendleton, obtained a clear view from the ridge of the Union forces arrayed against them and he estimated that there were 10,000. He reported this to Jackson, who replied, "Say nothing about it. We are in for it."

Pritchard Hill, July 2009

Around 4 p.m, Tyler attacked Fulkerson and Garnett by using an unorthodox approach with his brigade in "close column of divisions"—a brigade front of two companies with 48 companies lined up behind them in 24 lines, in all about 75 yards wide, and 400 yards long, a formation difficult to control and lacking offensive power at the front. The Confederates were temporarily able to counter this attack with their inferior numbers by firing fierce volleys from behind the stone wall. Jackson, finally realizing the strength of the force opposing him, rushed reinforcements to his left, but by the time they arrived around 6 p.m., Garnett's Stonewall Brigade had run out of ammunition and he pulled them back, leaving Fulkerson's right flank exposed. Jackson tried in vain to rally his troops to hold, but the entire Confederate force was forced into a general retreat. Kimball organized no effective pursuit.

Aftermath

Union casualties were 590 (118 killed, 450 wounded, 22 captured or missing), Confederate 718 (80 killed, 375 wounded, 263 captured or missing). Despite the Union victory, President Abraham Lincoln was disturbed by Jackson's audacity and his potential threat to Washington. He sent Banks back to the Valley along with Alpheus Williams's division. He also was concerned that Jackson might move into western Virginia against Maj. Gen. John C. Frémont, so he ordered that the division of Brig. Gen. Louis Blenker be detached from McClellan's Army of the Potomac and sent to reinforce Frémont. Lincoln also took this opportunity to re-examine Maj. Gen. George B. McClellan's plans for the defenses of Washington while the Peninsula Campaign was underway and decided that the forces were insufficient. He eventually ordered that the corps of Maj. Gen. Irvin McDowell, which was moving south against Richmond in support of McClellan, remain in the vicinity of the capital. McClellan claimed that the loss of these forces prevented him from taking Richmond during his campaign. The strategic realignment of Union forces caused by Jackson's battle at Kernstown—the only battle he lost in his military career—turned out to be a strategic victory for the Confederacy. The remainder of Jackson's Valley Campaign consisted of lightning movements and five victories against superior forces organized into three Union armies, which elevated him to the position of the most famous general in the Confederacy (until this reputation was later supplanted by his superior, Gen. Robert E. Lee).

Seldom during the Civil War was a general officer as gallant and as capable as Garnett treated so unjustly.... By any objective standard, Garnett had done the best at Kernstown that could reasonably have been expected under the circumstances as they existed. Ignorant of Jackson's tactical blueprint, his brigade out of ammunition and outflanked, Garnett took the only sane course of action. In doing so he saved the Valley army.

Peter Cozzens, Shenandoah 1862

After the battle, Jackson arrested the commander of his old Stonewall Brigade, Brig. Gen. Richard B. Garnett, for retreating from the battlefield before permission was received. The Stonewall Brigade's withdrawal, which came after it received the bulk of the Union fire and suffered the majority of Confederate casualties, uncovered the right of Fulkerson's Brigade, forcing it to also withdraw and starting a panic. He was replaced by Brig. Gen. Charles S. Winder. Garnett suffered from the humiliation of his court-martial for over a year, until he was finally killed in Pickett's Charge at the Battle of Gettysburg.

A Second Battle of Kernstown would occur in the Valley Campaigns of 1864.
