Not everyone served aboard ships during the war. Some men like Jose R. Zaragoza served on missions on some lonely atolls. When 19-year-old Zaragoza, a native of Los Angeles, California, joined the Coast Guard, he was sent on patrols in the Pacific coast of the United States defending against sabotage and invasion from the Japanese. Later he received instructions in the then-emerging and secretive field of Loran navigation and sent to Ulithi atoll, located between Guam and the Philippines where he worked in Long Range Aids to Navigation, which is akin to radar work. He served on Ulithi Island for 15 months.
