It’s next scheduled to air on D.C.’s PBS station Tuesday at 8 p.m., on Maryland’s PBS station Feb. 22 at 9 p.m., and Virginia’s PBS station Thursday at 9 p.m.

The two-part documentary, produced with the Army’s cooperation, tells the untold story of African Americans’ service in the military throughout the nation’s history to win and protect freedoms they themselves often didn't enjoy.

Hosted by Halle Berry, narrated by Avery Brooks, and introduced by retired Gen. Colin Powell, the four-hour documentary begins at the dawn of U.S. history to tell the story of African Americans who risked their lives to win and protect American freedom while striving to acquire it themselves.

In addition to film footage and photos, ‘‘For Love of Liberty” uses letters, diaries, speeches, journalistic accounts, historical text, and military records to document the accomplishments of African Americans who served in the military since the republic’s earliest days. Their personal stories give a moving account of service and sacrifice, from the Revolutionary War — whose first casualty was a black man, Crispus Attucks — to today's war against global terrorism.

‘‘It is a wonderful story...of a group of Americans who never lost their love of this country, never lost their faith in it or what the founding fathers had promised them,” said former Secretary of State Colin Powell. ‘‘And that’s why this story is simply called, For Love of Liberty.”
