Why did Clara Barton first volunteer to help the Union soldiers?

Clara Barton was working in the U.S. Patent Office in Washington, DC when the Civil War began. Like many women, she helped collect bandages and other much-needed supplies, but she soon realized that she could best support the troops by going in person to the battlefields.

Explanation:

Early in 1861 Barton returned to Washington, D.C. and, when the Civil War broke out, she was one of the first volunteers to appear at the Washington Infirmary to care for wounded soldiers. After her father's death late in 1861, Barton left the city hospitals to go among the soldiers in the field.
