Later that year, Tubman became the first woman to lead an armed assault during the Civil War.[107] When Montgomery and his troops conducted an assault on a collection of plantations along the Combahee River, Tubman served as a key adviser and accompanied the raid. On the morning of June 2, 1863, Tubman guided three steamboats around Confederate mines in the waters leading to the shore.[108] Once ashore, the Union troops set fire to the plantations, destroying infrastructure and seizing thousands of dollars worth of food and supplies.[109] When the steamboats sounded their whistles, slaves throughout the area understood that it was being liberated. Tubman watched as slaves stampeded toward the boats. "I never saw such a sight," she said later,[110] describing a scene of chaos with women carrying still-steaming pots of rice, pigs squealing in bags slung over shoulders, and babies hanging around their parents' necks. Although their owners, armed with handguns and whips, tried to stop the mass escape, their efforts were nearly useless in the tumult.[109] As Confederate troops raced to the scene, steamboats packed full of slaves took off toward Beaufort.[111]
More than 750 slaves were rescued in the Combahee River Raid.[112][113] Newspapers heralded Tubman's "patriotism, sagacity, energy, [and] ability,"[114] and she was praised for her recruiting efforts - most of the newly liberated men went on to join the Union army.[115]Tubman later worked with Colonel Robert Gould Shaw at the assault on Fort Wagner, reportedly serving him his last meal.[116] She described the battle by saying: "And then we saw the lightning, and that was the guns; and then we heard the thunder, and that was the big guns; and then we heard the rain falling, and that was the drops of blood falling; and when we came to get the crops, it was dead men that we reaped."[117]
