During World War II, Maragondon youths were among those called the colors. They fought in Bataan and Corregidor among other places. The survivors, upon return, helped organize and joined an underground force, Maragondon own liberators, the Guerillas, continue their resistance against the Japanese invaders. The unit joined the returning American forces in liberating Cavite, Quezon, and Batangas provinces.
A significant event during World War II against the Japanese invaders was the annihilation of one group of enemy soldiers at Barrio Bucal 4 up to the ricefields of Malainen Luma, Naic which led to the SONA. Those Guerilla soldiers were the Guerilla Hunters ROTC unit and Taparan's unit who fought the thousands of Japanese forces on February 3-6, 1945. This ambush was led by Captain Hunter Catalino del Rosario of Bucal 4 under the leadership of Col. Emmanuel V. de Ocampo, Commander of the 47th and 48th Regiment of Hunters ROTC squad.
