WASHINGTON (AP) _ A campaign to help raise $2.5 million for a memorial to black patriots of the Revolutionary War is under way in Washington.

District of Columbia City Council Chairman David A. Clarke, who kicked off the local effort Monday, said a national campaign will be launched in Washington on the Fourth of July.

The project is being headed by the Black Revolutionary War Patriots Foundation, formed by Maurice Barboza, a member of the Sons of the American Revolution, and Lena S. Ferguson, a member of the Daughters of the American Revolution. The Daughters of the American Revolution is already involved in identifying the black soldiers.

Barboza called the planned memorial ''a lasting honor to the more than 5,000 black patriots'' of the American Revolution.

''There are no statues in Washington, no motion pictures and no Fourth of July speeches extolling their bravery,'' he said.

The group wants Congress to approve construction of a memorial between the Washington Monument and the Lincoln Memorial, within sight of the headquarters of the Daughters of the American Revolution.

Under a measure introduced by Rep. Nancy Johnson, R-Conn., the foundation would have five years to raise the $2.5 million needed to build the monument.
