When we hear stories of enslaved people escaping to freedom, Blue Highway the Underground Railroad often comes to mind. It’s remembered as a brave and organized network of secret land routes and safe houses that led thousands of enslaved African Americans to freedom. But there’s another path, far less talked about, yet equally powerful and significant: the Blue Highway.
The Blue Highway refers to the secret maritime escape routes used by runaway slaves along the Eastern Seaboard of the United States. These water routes provided a dangerous but vital alternative to land travel for those seeking freedom. They played a major role in helping enslaved people reach northern states, Canada, or even other countries where slavery was outlawed.
The Blue Highway was not a single route but a wide network of rivers, coastal inlets, and ocean paths. Enslaved people used these waterways to escape from Southern slave-holding states. The goal was to reach free Northern states, port cities with abolitionist networks, or foreign destinations like the British Caribbean or Canada.
Many of the people who used the Blue Highway lived and worked near coastal areas. Some were fishermen, dockworkers, or sailors who had firsthand experience with ships, tides, and navigation. This knowledge gave them an advantage. They understood how to move without drawing attention and how to use the sea as a path to freedom.
Land routes came with major risks. Enslaved people had to travel on foot for days or weeks, often through forests or across plantations where they could be captured by patrols or informants. There were very few places to hide, and trusted allies were hard to come by.
The sea offered a different kind of risk but also a unique opportunity. For some, especially those living near ports, the Blue Highway was the only practical way out. Maritime routes could be faster than traveling over land and gave access to cities where free Black communities and abolitionists might help.
In some cases, enslaved people stowed away on ships headed north. Others worked as crew members, using their positions to escape. Some managed to secure or build small boats to travel along rivers and coasts under the cover of night.
The Blue Highway stretched from the Deep South to New England. Some key areas played a major role in this maritime network.
The Chesapeake Bay area, covering parts of Virginia and Maryland, was a hotspot for water-based escapes. The region had an active shipping industry, giving enslaved people more chances to escape by hiding on boats or sneaking onto outgoing ships.
Along the coasts of North and South Carolina, many enslaved people worked in ports or on plantations near rivers and marshes. These natural water routes made it easier for escapees to slip away, especially during bad weather or at night when patrols were light.
The Delaware River served as a vital escape route for those trying to reach Philadelphia, a major hub for free Black communities and abolitionist groups. From there, many made their way farther north or crossed into Canada.
Port cities like New York, Boston, and New Bedford in Massachusetts were destinations for many who traveled the Blue Highway. These cities had active anti-slavery societies and were often home to free Black populations who could offer help.
While many stories have been lost to history, a few documented escapes offer powerful examples of how the Blue Highway worked.
Moses Grandy was an enslaved man in North Carolina who worked on boats. His knowledge of maritime life helped him plan his eventual escape. After gaining his freedom, he published his life story, which included details of his time working on the water and how others used the sea to escape.
In 1848, a ship named The Pearl attempted to smuggle 77 enslaved people from Washington, D.C., to the North via the Potomac River and Chesapeake Bay. It was the largest known escape attempt by water. Unfortunately, the ship was caught, and the escapees were returned to slavery. Still, the event sparked national debate and added urgency to the abolition movement.
The Blue Highway was dangerous. While the sea provided a way out, it also came with serious risks.
Despite these dangers, many enslaved people still chose the water over land. It was a gamble they were willing to take for the chance at freedom.
Just as conductors helped guide enslaved people along the Underground Railroad, allies on the sea helped those escaping by water. Abolitionists in port cities would sometimes hide fugitives or help them get onto ships bound for freedom. Free Black sailors and ship workers could offer advice, clothing, or even direct help.
In some communities, entire networks of people worked quietly behind the scenes to help escapees reach safety. Some ship captains took great personal risks to transport fugitives. Though illegal, their moral beliefs led them to act.
The Underground Railroad was more organized and had more public attention, especially after the Civil War. The Blue Highway, by comparison, was less structured and more dangerous in some ways. But it was no less important.
The two systems often worked together. For example, someone might escape by boat to a Northern city and then continue inland using Underground Railroad contacts. Or someone could use the land route to reach a port city and then leave the country by ship.
The story of the Blue Highway is one of courage, resilience, and determination. It reminds us that the fight for freedom took many forms. Enslaved people did not wait for freedom to come—they found their own paths, whether by foot, by wagon, or by water.
Today, historical sites and museums are beginning to recognize and share these stories. Coastal cities, river towns, and maritime museums are uncovering new records and oral histories that tell of this hidden highway to freedom.
Understanding the Blue Highway gives us a fuller picture of how enslaved people resisted, survived, and escaped. It also honors the forgotten sailors, captains, dockworkers, and everyday people who took risks to help others reach freedom.
The Blue Highway runaway slaves used is a powerful but often overlooked part of American history. These maritime escape routes offered enslaved people an alternative path to freedom—one filled with both opportunity and danger.
Though less well-known than the Underground Railroad, the Blue Highway played a critical role in helping countless individuals escape bondage. It is a testament to human courage, determination, and the will to be free.
