Women have played different significant roles in different times in the history of wars worldwide. Clara Barton was one of the most remarkable persons in this case. She is best known as one of the founders of the American Red Cross and as a pioneer in the field of nursing. When her brother David became seriously ill following a barn-raising accident, 11-year old Clara nursed him for two years. On April 19, 1861, The Baltimore Riot killed and wounded several soldiers and civilians. A makeshift hospital was set up for the soldiers. As soon as she heard about the riots, Clara left house to tend the wounded, some of whom she knew personally. She collected food, medicine, clothing, and other supplies for the troops, many of whom arrived with just the clothes they were wearing. Clara wrote to friends urging them to help. Soon she built a volunteer supply network that lasted for a long time. Clara directed many of the relief operations herself.
