After the Japanese attack on Pearl Harbor, Royal Earle, Jr. and a buddy were on their way to join the the U.S. Marine Corps to take the fight to Japan. But his friend got snagged by the U.S. Navy instead. Unfazed, Earle endured Parris Island and Camp Pendleton and received training as a switchboard operator and wireman in preparation for service in the Pacific.

In this edition of "Veterans Chronicles," Mr. Earle walks us through his biggest challenge in boot camp and a big mystery during his time at Camp Pendleton. Then he describes operations in the Marshall Islands before the landing and combat on Saipan, which Earle says involved the most terrifying moments of his wartime experience.

Earle goes on to tell us about landing on Iwo Jima, navigating the black sand beaches, and the toll the Japanese inflicted on the Marines, including switchboard personnel. He also shares the most harrowing moment on Iwo Jima that brought a much happier ending than he first feared.

Finally, Mr. Earle explains the pride and honor her feels to have served in the Marines and how that feeling welled up in him many decades later.
