The military strategy during World War II that emphasized amphibious assaults and rapid advances was known as island-hopping. This strategy was particularly employed by the United States in the Pacific Theater against Japanese forces. Rather than capturing heavily fortified islands, American forces would bypass them, capturing weaker islands to establish bases and support further military operations. This approach allowed for swift advances and reduced casualties while effectively cutting off Japanese supply lines. Key battles, like those at Guadalcanal and Iwo Jima, exemplified this strategy’s effectiveness in reclaiming territory and weakening enemy positions.
