Marine Corps Sgt. Darrell S.Cole was one of 22 Marines who were awarded the Medal of Honor for the pitched combat that took place on the tiny volcanic island of Iwo Jima. He was originally assigned as a bugler but fought four times to change his rating, fighting in earlier battles as a machine gunner before being given a machinegun section. He was killed in action on February 19, 1945, and was posthumously awarded the Medal of Honor for heroism against the Japanese. The Navy named a destroyer, the USS Cole (DDG-67) after him.

Iwo Jima was part of the Japanese Empire and was an important strategic location as it was within fighter range of Japan. That would mean that P-51 fighters would be able to escort B-29 bombers to and from their targets. And bombers damaged over Japan could land on Iwo Jima instead of trying to fly all the way back to Tinian. The Japanese knew this and heavily fortified it with hidden bunkers and tunnels that crisscrossed the tiny (8-square mile) island.

Cole was born on July 20, 1920, in Esther, Missouri. He graduated from high school in 1938 in Esther and was active in sports, photography, and music.

Cole enlisted in the Marine Corps on August 25, 1941. Following boot camp at Parris Island, South Carolina, he was appointed to the Field Music School for training as a Marine Corps Field Musician (a bugler), because of his expertise with the French Horn in high school. Plus the Corps had a big shortage of buglers at that time. 

Because he had joined the Marines to fight, Cole sought to change to a Rifleman from a Field Musician. He had applied for a change in rating but was refused due to the shortage of buglers. He completed instruction and was transferred to the First Marine Regiment, First Marine Division. 

On August 7, 1942, he went ashore at Guadalcanal as part of the first American offensive of World War II. During the battle, due to the number of men getting wounded, Cole filled in as a Machine Gunner in the absence of the regular gunner.

Cole returned to the United States in February 1943 where he joined the First Batallion, Twenty-Third Marines, a part of the Fourth Marine Division at Camp Lejune, North Carolina. As the unit moved to California in preparation for combat he again asked for a change of rating; he was again denied.
