Dorr returned to Washington, DC after the end of the war and planned to go on a tour of the United States to conduct research for a series of magazine articles. This plan was cut short, however, when in late in the night of November 18, 1919, Dorr was hit by a motorcycle and was hospitalized with a broken arm and other serious injuries. The accident effectively ended the active period of Dorr's life, leaving a lasting impact on her memory and health.
