The Combahee Ferry Raid

On June 2, 1863, Harriet Tubman ledy Union guerrillas into Maryland to free slaves. From the article:

"On June 2, 1863, Harriet Tubman, under the command of Union Colonel James Montgomery, became the first woman to lead a major military operation in the United States when she and 150 African American Union soldiers rescued more than 700 slaves in the Combahee Ferry Raid during the Civil War.

"The success of the raid, which had also included the brave service of African-American soldiers, increased Tubman’s fame, and she went on to work on similar missions with the famed Massachusetts 54th Infantry before spending the final years of the war tending to injured soldiers. One hundred years after Tubman’s successes in South Carolina, a recently formed black feminist group took the name Combahee River Collective in her honor, also paying honor to Tubman’s work later in her life as a powerful advocate for women’s suffrage."
