Jackson's leading brigade, under the leadership of Brig. Gen. Richard Taylor, deployed on Prospect Hill and along the ridge to the east. The 1st Maryland Infantry, CSA, and Major Roberdeau Wheat's Louisiana "Tigers" battalion were thrown out in advance, entering the town and clearing it of Union skirmishers. The battle is notable in that the 1st Maryland CSA was thrown into battle with their fellow Marylanders, the Union 1st Regiment Maryland Volunteer Infantry., the only time in United States military history that two regiments of the same numerical designation and from the same state have engaged each other in battle. On the day of the battle Captain William Goldsborough of the 1st Maryland Infantry, CSA, captured his brother Charles Goldsborough of the 1st Maryland Infantry, USA, and took him prisoner.
