As the U.S. marks the 250th anniversary of the Battle of Bunker Hill, it might take a moment — or more — to remember why.

One of the turning points during the Revolutionary War was the Battle of Bunker Hill 250 years ago. A commemoration of the event takes place in the lead-up to America's 250th birthday next year.

Amanda Zettel, cofounder of Bunker Hill 250 and president of the Charlestown Preservation Society, said a smaller battle reenactment may happen earlier in June near Bunker Hill Community College.

NPR's Scott Simon talks with Jonathan Lane, of the consortium Revolution 250, about why the Battle of Bunker Hill won't be reenacted at Bunker Hill to celebrate the 250th anniversary of the U.S.
