 Between 4 and 12 July , New Jersey supported a United Nations push in the Kansong area , firing at enemy buildup and reorganization positions . As the Republic of Korea 's First Division hurled itself on the enemy , shore fire control observers saw New Jersey 's salvos hit directly on enemy mortar emplacements , supply and ammunition dumps , and personnel concentrations . New Jersey returned to Wonsan 18 July for an exhibition of perfect firing : five gun emplacements demolished with five direct hits .
