one of the major supply lines for the Army of the Potomac, capturing canal boats and cargo. They entered Rockville on June 28, also a key wagon supply road between the Union Army and Washington, tearing down miles of telegraph wire and capturing a wagon train of 140 brand new, fully loaded wagons and mule teams. This wagon train would prove to be a logistical hindrance to Stuart's advance, but he interpreted Lee's orders as placing importance on gathering supplies. The proximity of the Confederate raiders provoked some consternation in the national capital and Meade dispatched two cavalry brigades and an artillery battery to pursue the Confederates. Stuart supposedly told one of his prisoners from the wagon train that were it not for his fatigued horses "he would have marched down the 7th Street Road [and] took Abe & Cabinet prisoners." Stuart had planned to reach Hanover, Pennsylvania, by the morning of June 28, but rode into Westminster, Maryland, instead late on the afternoon of June 29. Here his men clashed briefly with and overwhelmed two companies of the 1st Delaware Cavalry under Maj. Napoleon B. Knight, chasing them a long distance on the Baltimore road, which Stuart claimed caused a "great panic" in the city of Baltimore. Meanwhile, Union cavalry commander Alfred Pleasonton ordered his divisions to spread out in their movement north with the army, looking for Confederates. Judson Kilpatrick's division was on the right flank of the advance and passed through Hanover on the morning of June 30. The head of Stuart's column encountered Kilpatrick's rear as it passed through town and scattered it. The Battle of Hanover ended after Kilpatrick's men regrouped and drove the Confederates out of town. Stuart's brigades had been better positioned to guard their captured wagon train than to take advantage of the encounter with Kilpatrick. To protect his wagons and prisoners, he delayed until nightfall and then detoured around Hanover by way of Jefferson to the east, increasing his march by . After a trek in the dark, his exhausted men reached Dover on the morning of July 1, the same time that his Confederate infantry colleagues began to fight Union cavalrymen under John Buford at Gettysburg. Leaving Hampton's Brigade and the wagon train at Dillsburg, Stuart headed for Carlisle, hoping to find Ewell. Instead, he found nearly 3,000 Pennsylvania and New York militia occupying the borough.
