If you’re driving between Washington D.C. and Richmond today, you’ll probably just see a blur of strip malls, data centers, and the notorious I-95 traffic. It’s hard to imagine that this exact stretch of Virginia was once the most contested patch of dirt in North America. To answer the question of where did the Battle of Fredericksburg happen, you have to look at the Rappahannock River. Specifically, the battle was centered in and around the city of Fredericksburg, Virginia, but the geography of the fight stretched from the riverbanks to the treacherous heights just west of the town.
It wasn't just a random spot on a map.
Geography dictated the slaughter. In December 1862, General Ambrose Burnside brought the Union Army of the Potomac to the northern banks of the Rappahannock, staring directly at a city that was basically a gateway to the Confederate capital. He wanted to move fast. He didn't. Because of a massive bureaucratic blunder involving delayed pontoon bridges, the Union army sat stuck on the Stafford Heights side of the river while Robert E. Lee’s Army of Northern Virginia dug in on the hills across the water.
The Urban Warfare of 1862
The fighting actually started right in the streets. This is one of the things people often forget—Fredericksburg was the site of the first major urban combat of the Civil War. Union engineers tried to build bridges under heavy fire from Confederate sharpshooters hidden in the basements and houses of the town. Eventually, Union troops had to cross in boats, storm the banks, and clear the city house by house.

If you visit today, you can still see the bullet scars in the brickwork of the older buildings. The town itself became a smoking ruin, looted and battered before the "main" battle even really kicked off. But while the street fighting was chaotic, it wasn't the deadliest part. That happened just outside the city limits.
Marye’s Heights: The Infamous Stone Wall
The most iconic location of the battle is Marye's Heights. Honestly, it's a chilling place to stand. The Confederates were positioned behind a sunken road and a stone wall at the base of a long, sloping hill. Burnside ordered wave after wave of Union soldiers to march across an open plain toward that wall.
They had no cover. None.

Confederate artillery on the heights above the wall had the entire field "zeroed in." They could hit anything that moved. General James Longstreet’s artillerist, Edward Porter Alexander, famously told his commander that a chicken couldn't live on that field once they opened up. He wasn't exaggerating. The Union troops were mowed down in rows. Thousands of men fell in a matter of hours, and not a single Union soldier even reached the stone wall.
Prospect Hill and the Slaughter Pen
While everyone focuses on the Stone Wall, a massive part of the battle happened about four miles south of the city. This area is known as Prospect Hill or the "Slaughter Pen." Here, the ground was much flatter and swampier.
General George Meade—who would later lead the Union at Gettysburg—actually found a gap in Stonewall Jackson’s lines. For a brief moment, it looked like the Union might actually win. They broke through the woods and hit the Confederate rear. But because of poor communication and a lack of reinforcements, Jackson’s men eventually pushed them back. Today, this part of the battlefield is preserved largely thanks to the American Battlefield Trust, as much of it was nearly lost to industrial development.

The Reality of the Stafford Heights
Don't ignore the other side of the river. The Union's massive artillery advantage was perched on Stafford Heights. From these bluffs, hundreds of cannons rained shells down onto the city and the Confederate positions. It was a spectacular sight, but ultimately, the cannons couldn't win the battle for the infantry. The river was the barrier that saved Lee's army and doomed Burnside's.
Why the Location Mattered
The Rappahannock River wasn't just water; it was a psychological and logistical wall. By the time the Union got across, the element of surprise was gone. Lee had weeks to turn the hills of Fredericksburg into a fortress.
- The Sunken Road: A natural defensive trench that made Confederate infantry nearly invincible.
- The Canal Ditch: A water-filled obstacle that broke up Union formations before they even reached the hills.
- Hazle Run: A creek that divided the Union forces and made coordination a nightmare.
Visiting the Battlefield Today
If you want to see where the Battle of Fredericksburg happened with your own eyes, the National Park Service manages several key spots. Start at the Fredericksburg Visitor Center on Lafayette Boulevard.
- Walk the Sunken Road. You can still see parts of the original stone wall, and the proximity of the houses to the battlefield is haunting.
- Drive to Prospect Hill. It’s quieter and gives you a better sense of the sheer scale of the conflict.
- Check out Chatham Manor. This was a Union headquarters and hospital on the Stafford side. You can look across the river and see exactly what Burnside saw as he planned his doomed attack.
- Visit the Angel of Marye's Heights monument. It commemorates Richard Kirkland, a Confederate soldier who risked his life to bring water to dying Union soldiers in the "no man's land" between the lines.
Actionable Next Steps
To truly grasp the geography, you should download the National Park Service "Civil War Battle Apps" or the American Battlefield Trust’s Fredericksburg map before you go. Most people just look at the stone wall and leave, but you’ll get a much better experience if you drive the full length of the Confederate line from the city down to Hamilton's Crossing.
If you're a history buff, try to visit in December. The cold, biting wind off the Rappahannock gives you a tiny, visceral sense of what those soldiers felt while shivering in the trenches or lying wounded on the frozen ground. Wear sturdy boots because the "Slaughter Pen" area is still quite marshy. Finally, check the Fredericksburg and Spotsylvania National Military Park website for ranger-led tours—hearing an expert describe the tactical errors while you're standing in the exact spot they happened is the only way to truly understand why this battle was such a disaster for the North.
