Pearl Harbor tributes
In 1990, leading up to the 50th anniversary of the attack on Pearl Harbor, Congress established the Pearl Harbor Commemorative Medal. This is also known as the Pearl Harbor Survivor's medal and was awarded to anyone who was in the U.S. Armed Forces and who was present in Hawaii on December 7, 1941, and participated in combat operations that day against the attack. The medal was also awarded to civilians who were killed or injured in the attack. A few years later, Congress amended the law to allow any person who was present in Hawaii on December 7, 1941, and was involved in combat operations against Japanese military forces attacking Hawaii, to receive the award. In both instances, there was a limited time period to apply for the award, and it is no longer issued.
