On July 8, 1944, Pfc. Guy Gabaldon single-handedly brought in 800 Japanese prisoners. He is credited with a total of 1,500 from June to August, 1944 from Saipan and Tinian islands.
Several hundred veterans of the Japanese Imperial Army took part in the re-creation of the Battle of Saipan, which was filmed on Okinawa. In addition, about 500 U.S. Marines from Camp Hansen on the island were used in this film.
Guy Gabaldon, who was the technical advisor for the film, was so impressed with Jeffrey Hunter portraying him that he named one of his sons after him.
