It's been 70 years since U.S. forces began a successful battle to capture the Japanese island of Iwo Jima during World War II.

Veterans who survived the bloody battle reunited in Washington, D.C. for a ceremony last week to honor the nearly 7,000 Marines that were killed in the fight.

Peter Johnson Jr. was on hand for the reunion between two dozen veterans who fought in the 36-day battle. 

He talked to Medal of Honor recipient, Hershel "Woody" Williams, who took out seven Japanese "pill boxes" with flamethrowers, saving countless Marines. 

His biggest regret, however, is the two Marines that were killed while protecting him.

"For some reason I survived and they didn't. And I don't have any answers for that. ... Why me?" said Williams, the last surviving Medal of Honor recipient from the historic battle.
