At 4 p.m. March 30, the Clark County Historical Museum, 1511 Main St., Vancouver, will host a screening of “Buffalo Soldiers: Fighting on Two Fronts” by local documentarian, Dru Holley. The film examines the contradictory roles played by Buffalo Soldiers in U.S. history, and how they fought on two sets of front lines: military conflicts abroad and civil rights struggles at home. See the trailer at pbs.org/video/local-usa-buffalo-soldiers-fighting-on-two-fronts-trailer/. A question-and-answer session with Holley will follow the film. Admission is free.
