Captain Arthur Junior Jackson was a United States Marine who received the Medal of Honor for his actions on Peleliu during World War II. At the age of 19, PFC Jackson single-handedly destroyed 12 enemy pillboxes and killed 50 enemy soldiers. He was also the last surviving recipient of the Medal of Honor from the Battle of Peleliu. On September 30, 1961, while serving at the Guantanamo Bay Naval Base, Jackson fatally shot a Cuban worker and suspected communist spy, in self-defense after Sabariego attacked him. He eventually buried the body in a shallow grave, but word leaked out. He left the Marine Corps in 1962 after being denied a court-martial to clear his name.
In January 1943, he began his recruit training at the Marine Corps Recruit Depot San Diego, California, and soon thereafter joined the 1st Marine Division in Melbourne, Australia in June 1943. On January 13, 1944, while taking part in the Cape Gloucester campaign, he carried a wounded Marine to safety in the face of well-entrenched Japanese troops on the slope of a steep hill, saving the man's life. For this action, he was awarded a Letter of Commendation. Following this, while serving with the 3rd Battalion, 7th Marines, he took part in the fighting and was wounded on Peleliu — for his heroic actions in that battle, he was awarded the Medal of Honor and was awarded his first Purple Heart. He again went into combat on Okinawa where, as a platoon sergeant with the 1st Marine Division, he was again wounded in action on May 18, 1945. That August, he was commissioned as a Marine second lieutenant. During ceremonies at the White House on October 5, 1945, President Harry S. Truman presented him with the nation's highest combat award — the Medal of Honor.
Post-war
Following the war, he served in northern China during the post-war occupation of that country. On his return to the United States, he returned briefly to civilian life, but, shortly after, entered the United States Army Reserve where, in 1954, he reached the rank of captain. Although he served with the army during the Korean War, he returned to the Marine Corps in 1959.
Guantanamo shooting
On the night of September 30, 1961, while serving at the Guantanamo Bay Naval Base, during a night of heavy drinking, Jackson claimed he discovered Rubén López Sabariego, a Cuban bus driver at Guantanamo he suspected was a communist spy, in a restricted area. On his own initiative, he and his executive officer, First Lieutenant William Szili, took López to a long-unused gate with the intention of removing him from the base. When they found the gate locked, Jackson sent Szili to find something to break the lock. When Szili returned, Jackson claimed that López attacked him and that he had to fatally shoot him with his.45 sidearm in self-defense. Jackson first threw the body over a cliff, then recovered it with Szili's assistance the next day and buried it in a shallow grave, but word leaked out. When his request for a court-martial to clear his name was denied, Jackson left the Corps in 1962. He remained active in the Army Reserves and eventually retired from that service in 1984. He also worked for the United States Postal Service. Jackson lived in Boise, Idaho, during his retirement, and died at a hospital there on June 14, 2017, at the age of 92.
