American Battlefield Trust’s map of the Battle for Culp’s Hill, Gettysburg
As twilight July 2 brought an end to the fighting on the Union left, Richard Ewell's assault on the opposite flank continued. Just before sunset, the division of Gen. Edward "Allegheny" Johnson began its charge up the steep, boulder-strewn slopes of Culp's Hill. Opposing Johnson's 4,700 Confederates, roughly 1,600 New Yorkers in Gen. George Sears Greene’s brigade were charged with holding the extreme right flank of the Union army and protecting its supply and communication artery, the nearby Baltimore Pike.
Johnson's men made their assault, only to run headlong into formidable breastworks erected by Greene's men. Union artillery from Power’s Hill supported Greene’s infantry. Gen. Maryland Steuart's brigade managed to outflank the Yankees, who fell back to a hastily built extension of their works. Increasing darkness led to great confusion as Greene was reinforced by depleted regiments from the I and XI Corps. Steuart’s Confederates successfully occupied the positions built by the brigades that had earlier departed to reinforce the Union left. The battle for Culp's Hill would resume at daylight.
