With the Combahee River Raid of 1863, Brigadier General Harriet Tubman of the Maryland National Guard became the first woman in U.S. history to lead a major military expedition. Read about it @mental_floss, including how Tubman, who liberated herself after being born into slavery, repeatedly returned to hostile territory to usher other slaves to freedom along the famed Underground Railroad:
@CultureDesk @mental_floss — minor correction: given she's being mentioned in a military rank, protocol says to refer to her by her highest attained rank and her unit: "Brigadier General Harriet Tubman of the Maryland National Guard."
@rob We should absolutely give her her rank! Changing the caption now!
