Early life and start of military career
Mann was born on July 31, 1854, in Altoona, Pennsylvania, the son of Anna Mann and Charles J. Mann. Charles J. Mann was an attorney and judge, and served as mayor of Altoona from 1884 to 1886. William A. Mann attended the schools of Altoona and obtained an appointment to the United States Military Academy. He graduated in 1875 and received a commission as a second lieutenant of Infantry. He served in the western United States throughout the 1870 and 1880s, mostly in assignments with the 7th Cavalry. As part of the 17th Infantry Regiment, he took part in the Sioux Indian campaign of 1890 to 1891.
General Mann left the Militia Bureau and was succeeded by Jesse McI. Carter. He became the first commander of the 42nd Division, nicknamed the Rainbow Division, which was composed of National Guard units from 26 states and the District of Columbia. The 42nd Division's activation was important in the development of the National Guard because it was the first time National Guard units from multiple states were organized together and it was the first time smaller Guard units were formed into a division. Mann led the Rainbow Division to France, but did not pass his physical exam, and so was not able to command the organization in combat. He then returned to the U.S. and commanded the Department of the East until he reached mandatory retirement age in late 1918.
