The Combahee River raid (1863) was a Union military operation in South Carolina during the Civil War in which Harriet Tubman, using her intelligence network and geographic knowledge, became the first American woman to lead a major military operation, liberating hundreds of enslaved African Americans.
The Combahee River raid was a Union Army operation along South Carolina's Combahee River in June 1863. Harriet Tubman, already famous as an Underground Railroad conductor, was working for the Union as a spy and nurse. She used her vast geographic knowledge and her social network among enslaved communities to gather intelligence about Confederate positions and the locations of enslaved people along the river. Then she helped guide Union gunboats upriver, where soldiers destroyed plantations and carried roughly 700 enslaved African Americans to freedom in a single night.
The CED's headline fact is this one (EK 2.20.B.3): during the raid, Tubman became the first American woman to lead a major military operation. But the deeper point is what the raid represents. Tubman's Underground Railroad work freed people a handful at a time through a covert civilian network. The Combahee raid freed hundreds at once with the backing of the U.S. military. Same person, same skills, but resistance had scaled up because the Civil War changed what was possible.
This term lives in Topic 2.20 (Race to the Promised Land: Abolitionism and the Underground Railroad) in Unit 2: Freedom, Enslavement, and Resistance. It directly supports learning objective 2.20.B, which asks you to explain the significance of Harriet Tubman's contributions to abolitionism and African Americans' pursuit of freedom. The raid is the proof point for EK 2.20.B.2 and 2.20.B.3, showing how Tubman leveraged the exact skills she built on the Underground Railroad (geography, trust networks, covert movement) in service of the Union war effort. For the exam, it's also your best single example of how African American resistance evolved from individual escape to organized, large-scale, military liberation.

Harriet Tubman and the Underground Railroad (Unit 2)
The raid is the climax of Tubman's story. The same skills she used on at least 19 trips south as a conductor, knowing the land and knowing who to trust, are what made her valuable to the Union Army as a spy. Think of the raid as the Underground Railroad's playbook run at military scale.
Fugitive Slave Acts (Unit 2)
The Fugitive Slave Acts of 1793 and 1850 made escape legally dangerous and forced freedom seekers to flee farther, even to Canada. The Combahee raid flips that script. Instead of enslaved people sneaking past federal law, the federal military was now actively liberating them.
Spirituals (Unit 2)
Tubman sang spirituals to signal enslaved people that it was time to leave. That coded-communication tradition is the throughline. Whether on a nighttime Underground Railroad escape or a wartime raid, freedom depended on messages enslavers couldn't read.
The Combahee River Collective (Unit 4)
In the 1970s, Black feminist activists named their organization the Combahee River Collective specifically to honor Tubman's raid. If you're building a continuity argument about Black women's leadership in liberation movements, this is a ready-made thread from Unit 2 to Unit 4.
The Combahee River raid appeared on the 2025 exam's first short-answer question, so this is not an obscure footnote. Multiple-choice stems tend to test it in three ways. First, the straight ID, asking what the raid is most accurately understood as (a Union military operation that liberated enslaved people, led by Tubman). Second, the evolution question, asking how the 1863 raid represents a shift in African American resistance from covert escape to armed, organized liberation. Third, the skills question, asking which operation shows how Tubman's social network among enslaved communities powered her intelligence gathering for the Union Army. For SAQs, be ready to use the raid as specific evidence for Tubman's significance (LO 2.20.B), and don't just say she was a conductor. Name the wartime roles too, spy and nurse, and the first-woman-to-lead-a-major-military-operation fact.
Both involve Tubman freeing enslaved people, but they're different categories of resistance. Her Underground Railroad work was covert and civilian, leading about 80 people to freedom over roughly 19 trips through a secret abolitionist network. The Combahee River raid was an overt military operation, run with Union Army gunboats and soldiers, that freed hundreds in one night. If a question asks about a 'major military operation' or anything during the Civil War, it's the raid, not the railroad.
During the 1863 Combahee River raid in South Carolina, Harriet Tubman became the first American woman to lead a major military operation.
The raid liberated hundreds of enslaved African Americans in a single operation, far more than Tubman freed in all her Underground Railroad trips combined.
Tubman's value to the Union came from her geographic knowledge and her social network among enslaved communities, the same assets she built as an Underground Railroad conductor.
The raid marks an evolution in African American resistance, from covert individual escapes to organized, military-backed liberation during the Civil War.
On the exam, the raid is your go-to evidence for LO 2.20.B, explaining the significance of Tubman's contributions to African Americans' pursuit of freedom.
It was a June 1863 Union military operation along the Combahee River in South Carolina during the Civil War. Harriet Tubman guided the operation using intelligence from enslaved communities, and it liberated roughly 700 enslaved African Americans, making her the first American woman to lead a major military operation.
No. The Underground Railroad was a covert civilian network of Black and white abolitionists; the Combahee raid was an official Union Army military operation. Tubman did both, but the raid happened during the Civil War with gunboats and soldiers, not safe houses and conductors.
About 700 enslaved African Americans were liberated in one night. Compare that to Tubman's Underground Railroad career, where she led around 80 people to freedom across at least 19 trips south.
Because during the Combahee River raid she planned and guided a major Union operation, supplying the intelligence and route knowledge that made it work. The CED states this directly in EK 2.20.B.3, so it's the exact phrasing the exam expects.
Yes. It's named in the CED under Topic 2.20 (EK 2.20.B.3), and it appeared on the 2025 exam's first short-answer question. Expect questions about what the raid was and how it shows the evolution of African American resistance.
