The fateful day of December 7, 1941 came. America was at war. Jones left his teaching position to enter the United States Marine Corps. Jones reported to the Marine base at Quantico, Virginia, where he graduated as a second lieutenant on August 25, 1942. From Quantico, Henry Will was sent to New River, North Carolina, where he completed his training as a paratrooper in October 1942.
While in this zone, he saw service and suffered a slight wound. Henry Will remained in Bougainville until January 12, 1944, when his paratrooper detachment was sent home to be organized into the 5th Marine Division. As the war progressed, paratroopers were no longer needed. Jones and his buddies were retrained to be regular infantry fighting Marines.
Captain Jones landed with his outfit at San Diego on February 7, 1942. Ten days later, he was back home in Lakeland on a well-earned leave. The following day, Lt. Jones became Captain Jones. Before his return to the Marines, Captain Jones drove to Dexter for one last visit.
Captain Jones' first new assignment was as commander of Company I, 3rd Battalion, 7th Marine Division. He led his company in the invasion of Peliliu Island, the main island of the Palau Islands. His last two letters were dated October 12th and 13th. On October 18th, 1944, Captain Henry Will Jones was reported killed in action when his tank was struck by enemy aerial bomb buried just beneath the surface of the ground.
In honor of his admirable valor, the Secretary of the Navy posthumously awarded the Silver State Medal to Jones' family. On March 24, 1997, the State of Georgia honored Captain Henry Will Jones with the naming of a bridge in his home county of Lanier. The resolution read:
WHEREAS, Captain Henry Will Jones of Lanier County was killed in action on October 18, 1944, while serving as a commanding officer of a United States Marine Corps company in the South Pacific during World War II; and he was awarded posthumously the Silver Star Medal by the Secretary of the Navy in recognition of his exemplary valor; and
WHEREAS, he had graduated from the University of Georgia and was an instructor in the Laurens County school system when he enlisted in the military following the Japanese attack on Pearl Harbor; and he completed officers candidate school, paratrooper training, and advanced military training with the Marine Corps and was recognized as a distinguished officer with considerable potential; and
WHEREAS, his fearless leadership, great personal valor, and unrelenting devotion to duty in the face of extreme danger contributed substantially to the success of his division in capturing a vital stronghold; and his courage and determination upheld the highest traditions of military service; and
WHEREAS, he enjoyed nature and had a strong attachment to the region in which he had spent his youth exploring the rivers, forests, and wildlife; and he often expressed his dream of returning to the Alapaha River in his letters home to his family; and
WHEREAS, it is most fitting and appropriate to honor this outstanding young officer who so gallantly gave his life for his country.
NOW, THEREFORE, BE IT RESOLVED BY THE GENERAL ASSEMBLY OF GEORGIA that the bridge on Georgia Highway 37 that crosses that portion of the Alapaha River in Lanier County be designated the Captain Henry Will Jones Bridge.
BE IT FURTHER RESOLVED that the Commissioner of Transportation is authorized and directed to place signs at appropriate locations along the highway designating the bridge over the Alapaha River as the Captain Henry Will Jones Bridge.
A Henry Will Jones chapter of the Future Teachers of America was established at Dexter High School.
Jones was inducted into the Abraham Baldwin Agricultural College Athletic Hall of Fame in 2013.
