What were some roles that women had in the civil war that was a major impact on the war?

Women disguised themselves as men in order to fight in the Civil War for both North and South. also, thousands of other women worked as nurses and worked for volunteer brigades.

i know someone already said that but it's directly copied from the internet so here's a different version.

More than 400 women disguised themselves as men and fought in the Union and Confederate armies during the Civil War. During the Civil War, however, American women turned their attention to the world outside the home. Thousands of women in the North and South joined volunteer brigades and signed up to work as nurses.
