Nils Mockler joined the U.S. Marine Corps at the age of 17, only because they wouldn't let him join when he was 16. Upon enlisting in 1944, Mockler completed boot camp and was soon tapped as a combat intelligence scout. He also dabbled in explosives as you'll hear. After more training in Hawaii, Mockler and many other Marines left for Iwo Jima, where they would land in February 1945 and become part of one of the most vicious battles in the entire war.

In this edition of Veterans Chronicles, Mockler takes us on board his ship as the battle plans were opened up and military planners thought Iwo Jima wold be a two-day mission. He also shares his experience coming ashore on D+1 and the fierce Japanese resistance he and the other Marines faces. 

Mockler also describes the battle-hardened unit he was attached to, the apprehension of sitting in his foxhole through the night in anticipation of Japanese attacks, and watching the cemetery of American service members grow far beyond what the battle planners could have imagined. And he describes the exhiliration of watching the American flag raised atop Mount Suribachi.
