The Potomac River is a major river in the Mid-Atlantic region of the United States that flows from the Potomac Highlands in West Virginia to the Chesapeake Bay in Maryland. It is 405 miles (652 km) long, with a drainage area of 14,700 square miles (38,000 km2), and is the fourth-largest river along the East Coast of the United States and the 21st-largest in the United States.

U.S. Route 340 is a spur route of US 40, and runs from Greenville, Virginia, to Frederick, Maryland.

The Battle of White Oak Swamp took place on June 30, 1862, in Henrico County, Virginia, as part of the Seven Days Battles of the American Civil War. As the Union Army of the Potomac retreated southeast toward the James River, its rearguard under Maj. Gen. William B. Franklin stopped Maj. Gen. Thomas J. "Stonewall" Jackson's divisions at the White Oak Bridge crossing, resulting in an artillery duel, while the main Battle of Glendale raged two miles (3 km) farther south around Frayser's Farm. White Oak Swamp is generally considered to be part of the larger Glendale engagement. Because of this resistance from Brig. Gen. William B. Franklin's VI Corps, Jackson was prevented from joining the consolidated assault on the Union Army at Glendale that had been ordered by General Robert E. Lee, producing an inconclusive result, but one in which the Union Army avoided destruction and was able to assume a strong defensive position at Malvern Hill.
