Calvin Fletcher became Indiana's state colonization society's manager in 1829. Also in 1829 he represented four enslaved women in a suit against their enslaver, William Sewall, in which the court ruled in favor of the women's freedom. In 1852, Calvin Fletcher's long-standing interest in colonization led him to support a State Board of Colonization that would provide state funds to assist blacks living in Indiana to establish a colony in Africa. He also helped found the Indiana Total Abstinence Temperance Society, and in 1863 led the Freedman's Aid Commission. Military assistance Fletcher and his family also contributed to and participated in the American Civil War. Three of Fletcher's sons served in the Union army. He also supported the organization of the U.S. colored troops in Indiana during the war. The 28th Regiment U.S. Colored Troops used his farm land to train between December 1863 and April 1864. During the war, Fletcher helped provide aid for soldiers' families, assisted local efforts to welcome returning soldiers home, and served on the city's Sanitation Committee. At the request of Indiana Governor Oliver P. Morton, Fletcher purchased arms for Indiana's regiments. After the war, Fletcher contributed to the Freedman's Aid Society. Public welfare Fletcher assisted the Indianapolis Benevolent Society, a local organization that helped the city's poor, serving for years as its secretary. He was also interested in the efforts of the Widows and Orphans Society and active in the temperance movement. Methodist Church Fletcher was known as a very religious man.
