When the Civil war began in 1861, Barton was working as the first female clerk in the Patent Office in Washington D.C. But reports of suffering soldiers roused her to action. Besides nursing the wounded, she carried supplies and medicines to the battlefield.
Clara barton created a bureau to search for missing Civil War soldiers and mark the graves of the dead.
Barton’s war efforts left her exhausted and ill. In 1869, she went to Switzerland to recover. There, barton learned about the International red Cross, an organization devoted to the relief of suffering resulting from war. In 1870-1871, she took part in Red Cross activities during the Franco-Prussia war. Two years later, Barton returned home and set about forming an American red Cross. In 1881, she achieved her goal and served as the organization’s first president for 22 years. Before retiring in 1904, Barton expanded the efforts of the Red Cross to include aid to victims of peacetime disasters, such as floods and hurricanes.
