The Rappahannock River is a river in eastern Virginia, in the United States, approximately 184 miles (296 km) in length. It traverses the entire northern part of the state, from the Blue Ridge Mountains in the west, across the Piedmont, to the Chesapeake Bay, south of the Potomac River.
An important river in American history, the Rappahannock was the site of early settlements in the Virginia Colony, and, later, it was at the center of a major theatre of battle in the American Civil War. Due to its significance as an obstacle to north-south movements, it, in effect, functioned as the war's eastern-theatre boundary, between the "North" (the Union) and the "South" (the Confederate States of America).
The river drains an area of 2,848 square miles (7405 km²), approximately 6% of Virginia. Much of the watershed is rural and forested, but it has experienced increased development in recent decades because of the southward expansion of the Washington, D.C. suburbs.
The Rappahannock River rises at Chester Gap, a wind gap in the Blue Ridge Mountains a few miles southeast of Front Royal, Virginia, near the single point where Warren, Fauquier, and Rappahannock counties come together. It flows southeastward, past Remington, Kelly's Ford, and Richardsville, before it is joined by the Rapidan River, its largest tributary, from the right. Then the Rappahannock passes through the city of Fredericksburg. Southeast of Fredericksburg, it begins to slow and widen into a brackish tidal estuary approximately 50 miles (80 km) long. It passes two small, but historic, river towns, Port Royal and Port Conway, which sit opposite each other, the former on the south bank, the latter on the north. Then it flows past Tappahannock on its southern bank, a point where the river is well over a mile wide. The last settlements of any size before reaching salt water are Irvington and White Stone Beach.
The broad river enters Chesapeake Bay approximately 15 miles (24 km) south of the mouth of the Potomac and approximately 50 miles (80 km) east of the state capital, Richmond. At the point where the river enters the bay, between Windmill Point, on the north, and Stingray Point, on the south, it is more than 3.5 miles (5.6 km) wide. This area, the estuary south of the Northern Neck peninsula is a productive oyster and crab fishery.
Above Fredericksburg, the Rappahannock provides fine opportunities for recreational canoeing and kayaking. Most of the rapids are Class I and Class II in difficulty, but, near Remington, there are some rapids that are considered to be Class III.
The name of the river comes from an Algonquian word, lappihanne (also recorded as toppehannock), meaning "river of quick, rising water" or "where the tide ebbs and flows," the name used by the local native population, the Rappahannock tribe.
Although there had been a few small hamlets along the lower Rappahannock during early colonial times, the settlement of the Rappahannock River valley began in earnest during the first years of the eighteenth century, at the urging of Governor Alexander Spotswood. The James River had been surveyed up to its fall line, the point where, geologically, continental bedrock meets the sedimentary rocks and alluvial soils of the coastal plain. Spotswood encouraged settlement in a river valley other than that of the James. In 1714, he began soliciting immigrants from the Siegen, Germany and Switzerland to homestead on lands he controlled near the confluence of the Rappahannock and the Rapidan. Known as the Germanna settlement(s), these villages were founded in order to exploit the iron ore deposits of the region.
During the American Civil War, the river, with few convenient fords and fewer bridges, provided a barrier and defensive line behind which movements of troops could be accomplished with little fear of attack from the river-side flank. It was an especially difficult barrier for Union troops to overcome in their attempts to thrust into southern Virginia. Control of the river changed hands many times during the course of the war. Significant battles fought along the river include the Battle of Fredericksburg and the Battle of Rappahannock Station. The defensive line at the river was finally circumvented by Ulysses S. Grant in the Wilderness (or Overland) Campaign of 1864, resulting in the ultimate Union victory.
In some 18th- and 19th-century documents, including some Civil War records, the Rappahannock River was referred to as "Hedgeman's River"; a 1736-1737 survey labeled the Rappahannock above the mouth of the Rapidan as "Cannon", and further upstream it was identified as "Hedgeman's River." Who Hedgeman was is uncertain.
