While the disciplined mind of an engineer provided the foundation for his military career, it was in the crucible of battle that Andrew Atkinson Humphreys would forge his legacy.

The Unbreakable Hinge: How Humphreys Held the Line at Gettysburg

On the eve of the second day of the Battle of Gettysburg, Major General Andrew A. Humphreys found himself in command of the 2nd Division of the III Corps, Army of the Potomac. An experienced officer known for his meticulous nature and sharp intellect, he was about to face the most severe test of his career. His division, composed of brave but weary veterans, would soon be thrust into one of the most vulnerable and violently contested positions on the entire battlefield, a salient that threatened the stability of the entire Union line.

The III Corps’ Perilous Advance

The crisis began not with a Confederate attack, but with a controversial decision by Humphreys’ own corps commander, Major General Daniel Sickles. Dissatisfied with his assigned position on the lower stretch of Cemetery Ridge, Sickles, without orders, advanced his entire III Corps forward to occupy what he considered higher ground along the Emmitsburg Road, with his left flank anchored in a rocky area known as Devil’s Den and his center bent at a sharp angle at the Sherfy Farm’s Peach Orchard.

This maneuver created a massive, exposed salient, a bulge in the Union line that could be attacked from multiple sides. Humphreys’ division was ordered to occupy the northern portion of this new line, a long, thin front stretching along the Emmitsburg Road. From his position, Humphreys could see the danger immediately; his men were in the open, with their right flank unconnected to the adjacent II Corps—a "flank in the air."

A Division in the Crossfire

As the afternoon of July 2nd, 1863, wore on, Humphreys prepared his men for the inevitable assault. His division consisted of two brigades, with a third temporarily detached, holding a line that was both long and dangerously exposed.

The table below details the disposition of his command during this critical period.

Unit	Commander	Key Position	Approx. Engagement Time (July 2nd)	Action / Movement
2nd Division, III Corps	Maj. Gen. A. A. Humphreys	Emmitsburg Road, North of the Peach Orchard	4:00 PM – 7:30 PM	Directed defense and fighting withdrawal.
1st Brigade	Brig. Gen. Joseph B. Carr	Southern portion of the division’s line, near the Peach Orchard	4:00 PM – 6:30 PM	Withstood initial assaults before being forced to retreat.
2nd Brigade	Col. William R. Brewster	Northern portion of the division’s line	5:30 PM – 7:30 PM	Engaged by Barksdale’s brigade; conducted a masterful fighting withdrawal.

When the Confederate assault finally crashed into the III Corps salient, it did so with terrifying force. While much attention is given to the fighting at Little Round Top and Devil’s Den, the collapse of the Union position at the Peach Orchard directly threatened Humphreys’ flank and rear.

The Fighting Withdrawal: Leadership Under Fire

As Confederate brigades under William Barksdale and Cadmus Wilcox shattered the Union defenses to his south and west, Humphreys’ division was caught in a deadly pincer. With cannon fire tearing through his ranks from the front and musket fire raking his flank, his line became untenable. It was here that Humphreys’ personal courage and tactical skill shone brightest.

• Personal Bravery: Mounted on his horse, he was a conspicuous target, riding calmly along the disintegrating line to issue orders and steady his men. Eyewitnesses reported his horse being shot from under him as he coolly directed the complex maneuver. His staff suffered immensely, with nearly every member killed, wounded, or unhorsed.
• Tactical Acumen: A simple retreat would have been a rout, triggering a catastrophic collapse of the Union flank. Instead, Humphreys executed one of the most difficult maneuvers in warfare: a disciplined fighting withdrawal under extreme pressure. He had his men fall back by stages, turning to fire a volley, then retreating another short distance. He was essentially fighting in two directions at once—against the Confederates in front and the ones now on his flank.

This orderly retreat was the critical action that saved the Union flank. It bought precious minutes for reinforcements from the II Corps to be rushed into the breach, forming a new defensive line along Cemetery Ridge. Humphreys’ division served as the unbreakable hinge; though it was bent and battered back, it did not snap. It slowed the Confederate onslaught just long enough for the main Union line to solidify.

The cost was staggering. Humphreys’ division suffered over 2,000 casualties, a loss rate approaching 40%, among the highest of any Union division in the entire battle. They had been sacrificed to correct their commander’s strategic error, but in their sacrifice, they had prevented a disaster.

His masterful performance under fire at Gettysburg did not go unnoticed, setting the stage for a new role where his strategic mind, rather than his frontline courage, would be the Army’s greatest asset.

Following his cool-headed courage and tactical brilliance in the chaotic maelstrom of the Peach Orchard, Andrew Atkinson Humphreys’ unique talents were soon recognized with an even greater, albeit less visible, responsibility.
