The Harlem Hellfighters' Great War (2017)

Nicknamed the "Harlem Hellfighters", these African-Americans wanted to become ordinary citizens like everyone else. They saw fighting heroically in the trenches as their chance to achieve this. In 1918, the 15th New York National Guard Regiment became the most highly decorated unit of the First World War.

Unfortunately the movie The Harlem Hellfighters' Great War is not yet available on HBO Max.
