 As ordered, the brigade advanced several hundred yards beyond the Federal lines and engaged the vastly superior Confederate forces in brutal hand-to-hand combat.Their stubborn fight held up the Confederate attack for thirty minutes, allowing the rest of the XIX Corps to withdraw and join forces with the VI Corps about a mile to their rear near Belle Grove Plantation.The 47th Pennsylvania Infantry, on the Brigade's extreme right flank, was almost immediately overrun, hindered by a dense fog and Union 8th Corps men fleeing through its line.
