The regiment was commanded by Colonel Patrick Henry O’Rorke and brought 526 men to the field. Colonel O’Rorke and 25 enlisted men were killed, 2 officers and 9 enlisted men were mortally wounded, 3 officers and 75 enlisted men were wounded and 18 enlisted men were missing. Lieutenant Colonel Louis Ernst took command of the regiment when O’Rorke fell.

The 140th was marching across the north slope of Little Round Top to the support of Sickle’s 3rd Corps on July 2nd. It was intercepted by General Gouverneur Warren, who was desperately improvising a defense of the vital hill. By luck, Warren had commanded the brigade in the past and was well known to Col. O’Rorke. When according to one story Warren said, “Paddy, give me a regiment!” O’Rorke was quick to oblige with his own.

After cresting Little Round Top he dismounted and led the regiment in column of fours toward the Confederates threatening to break the Union line, drawing his sword and shouting, “Down this way, boys!” As the men began to form a line and O’Rorke shouted, “Here they are men, commence firing!” a Confederate about forty feet away shot O’Rorke in the neck. The Confederate did not long survive the Colonel; after the battle seventeen holes were counted in his body.

The assault by the 140th was one of the decisive moments in the saving of Little Round Top and the Union left flank during the battle.

From the wayside marker near the monument:

“The regiment melted away like snow. Men disappeared as if the earth had swallowed them.”

-Captain Porter Parley
140th New York Infantry

Shortly after noon on May 5, the battleline of the 140th New York burst from the woods to your right-rear – the first regiment to advance against the Confederates here in Saunders Field.

Undaunted by a devastating Confederate fire, the 529 New Yorkers sprinted across the field and assailed the Confederates along the woodline before you. But supporting units, Caught in the tangled woods north of the field, could not keep pace. Confederate fire raked the 140th exposed right flank. For perhaps 30 minutes the 140th New York clung to its foothold in the woods. Then, with nearly half its men shot or captured, the regiment retreated.

The advance of the 140th New York was but the first bloodletting in what would be two days of savage fighting in and around Saunders Field.

From the monument on the Wilderness battlefield:

Number Engaged 529. Casualties 23 killed, 118 wounded, 114 missing.
