On December 7, 1941 the Japanese launched a sneak attack on Pearl Harbor. This attack on the United States Pacific Fleet was a total tactical success. Using 360 planes and midget submarines, were able to sink the USS Arizona, USS California, USS Maryland, USS Oklahoma, USS Pensylvania, USS Tennessee, and the USS Utah. They also destroyed Hickman Field, the US air base on Hawaii.
The result of this attack was a declaration of war on Germany, Italy, and Japan by the United States. It also had an effect on the Japanese-Americans living on the West Coast. American citizens had property taken away and were incarcerated by their fellow citizens with executive order 9066. Even through this racist act many Japanese-Americans volunteered for service in the United States Army. This unit was given the derogatory name of Nisei. Yet, those Japanese-Americans who fought in the United States Army got an award for their courage and endurance.
