Gouverneur K. Warren
When Meade discovered this situation, he dispatched his chief engineer, Brig. Gen. Gouverneur K. Warren, to attempt to deal with the situation south of Sickles' position. Climbing Little Round Top, Warren found only a small Signal Corps station there. He saw the glint of bayonets in the sun to the southwest and realized that a Confederate assault into the Union flank was imminent. He hurriedly sent staff officers, including Washington Roebling, to find help from any available units in the vicinity.
