I am stunned that no one has mentioned the Gibraltar Brigade in the Army of the Potomac's 2nd Corps. Made up of the 8th and 4th Ohio, 7th West Virginia, and 14th Indiana, this veteran brigade played a key role in the Union victory against Jackson's vaunted army at the Battle of Kernstown (2nd Winchester). As part of French's division in the AOP, it occupied the ridge in front of the Sunken Road at Antietam longer than any other attacking unit. At Gettysburg, three of its regiments held off the Confederate onslaught against East Cemetery Hill in the twilight of July 2nd, while the 8th Ohio single-handedly flanked, enfiladed, and routed much of Brockenborough's brigade from its advance position on the Emmittsburg Road on July 3rd. Numerous regimental monuments on both battlefields testify to the brigade's toughness on defense and its ability to inflict damage on the enemy when ordered to attack. Hurrah for the Bully Gibraltar Brigade!
