Brigadier General Franklin Augustus Denison, A Soldier's Story

Brigadier General Franklin Augustus Denison
Born 1862c. - Died April 14, 1922

Franklin Augustus Denison was born around 1862 in San Antonio, Texas. While still young, he and his family relocated to the Chicago area, where his education and professional life would ultimately intersect with military service and public leadership.

Denison graduated from Lincoln University in 1888 and later earned a law degree from Northwestern University in 1890. In 1891, he was appointed Assistant Attorney General of Illinois. Alongside his legal career, Denison played a central role in the formation of the 8th Infantry Regiment of the Illinois National Guard. The unit was historically significant as one of the few African American regiments commanded by African American officers at a time when such opportunities were extremely limited.

During the Spanish-American War, Denison deployed to Cuba with the 8th Illinois. Fluent in Spanish, he served as president of a general court-martial, a role that reflected both his legal training and his standing within the regiment.

After returning from Cuba, Denison continued his advancement in the Illinois National Guard. He served as Chief Quartermaster of the 4th Brigade before assuming command of the 3rd Battalion. He was later assigned to Fort Sam Houston, where he participated in border security operations during the Mexican Expedition, guarding the U.S.–Mexico border amid escalating instability.

At the outset of World War I, the 8th Illinois was redesignated as the 370th Infantry Regiment. Denison deployed to France with the unit, where it was involved in preparations for major Allied operations, including groundwork connected to the Meuse-Argonne Offensive. He returned to the United States before the battle itself but remained part of the senior leadership guiding African American troops during the war.

In 1918, Franklin Augustus Denison became the first African American officer to rise above the rank of colonel, achieving the rank of brigadier general, a milestone in U.S. military history during an era of institutional segregation.

Brigadier General Denison retired from military service in 1922. He died on April 14, 1932, and is buried at Oakwoods Cemetery in Chicago, Illinois. His career reflects both distinguished service and the barriers Black officers navigated in the late nineteenth and early twentieth centuries, leaving a legacy marked by persistence, competence, and command.
