Second Division

At Gettysburg on July 2, 1863, the Army of the Potomac's Cavalry Corps Second Division, commanded by Brigadier General David McM. Gregg, with the First Brigade under Colonel John B. McIntosh and the Third Brigade under Colonel J. Irvin Gregg, left Hanover and took position about noon at the junction of the Hanover Road and the Low Dutch Road, with the First Brigade on the right and the Third on the left connecting with the infantry pickets, while the Second Brigade under Colonel Pennock Huey had been sent to Westminster. After a sharp skirmish with the 2d Virginia Infantry, the division took and held Brinkerhoff Ridge, then about 10 p.m. the two brigades withdrew and bivouacked for the night on the Baltimore Pike a mile east of Rock Creek Bridge. On July 3, the division took position with its right on Hanover Road. The Second Brigade of the Third Cavalry Division was on the right, but when General Custer received an order from General Pleasanton to rejoin his division, he was relieved about 2 p.m. by the First Brigade. After a large Confederate cavalry force under General Stuart, screened by woods, was discovered, General Gregg ordered Custer to remain in support of McIntosh until the Confederate cavalry could be driven back. Custer and McIntosh, together with the batteries of Randol and Pennington, were soon hotly engaged with Confederate cavalry and artillery. About 3 p.m., Stuart charged with his reserves under Hampton and Fitzhugh Lee, but the attack was repulsed, closing operations on the field. Casualties were 5 men killed, 7 officers and 31 men wounded, and 1 officer and 11 men captured or missing, for a total of 56.
