Who served as a nurse, scout, and spy for the Union Army during the Civil War?

Harriet Tubman's role during the Civil War was multifaceted, as she indeed served not only as a nurse but also as a scout and a spy for the Union Army. Tubman is best known for her work on the Underground Railroad, where she helped enslaved individuals escape to freedom. During the Civil War, she leveraged her deep knowledge of the land and her ability to navigate it stealthily to gather intelligence for Union forces.

As a nurse, she cared for soldiers, and in her role as a scout, she led expeditions that helped free enslaved individuals and provide crucial information to Union generals. Her intelligence work included guiding troops through territory and planning military strategies based on her knowledge of the area and its inhabitants. This combination of bravery and skill made her an invaluable asset to the Union effort.

The other individuals listed had significant contributions during this period, but they did not specifically hold the roles of nurse, scout, and spy in the same capacity as Tubman. Clara Barton is known for founding the American Red Cross, Sojourner Truth was an abolitionist and women's rights activist, and Mary Todd Lincoln was the wife of President Abraham Lincoln.
