Beginning on July 2, 1863, the Battle of Little Round Top at Gettysburg was a key battle in the Civil War.
Confederate troops began an attack to drive northeast up the Emmitsburg Road in the direction of Cemetery Hill, rolling up the Union left flank that morning. Little Round Top was undefended by Union troops at this point. General Sickles, defying direct orders, moved his corps a few hundred yards west to the Emmitsburg Road and the Peach Orchard (far right of the image). His left flank was anchored in Devil’s Den, the rocky outcropping in the lower left part of this picture.
When General Meade discovered this situation, he dispatched his chief engineer to attempt to deal with the situation south of Sickles’s position. Climbing Little Round Top, Warren saw the reflection of bayonets in the sun to the southwest and realized that a Confederate assault into the Union flank was imminent. Union troops under the command of Colonel Vincent intercepted the orders to fortify Little Round Top, and directed his troops to defend the high ground, setting the stage for the pending battle.
After 2 days of fierce fighting, 2,996 Union troops had been engaged with 565 casualties (134 killed, 402 wounded, 29 missing). Confederates saw 4,864 engaged with 1,185 casualties (279 killed, 868 wounded, 219 missing).
