Only one other notable event remained in the Indochina drama. In May 1975 Khmer Rouge forces boarded and captured the crew of the "Mayaguez", an unarmed U.S.-registered freighter. The United States bombarded military and fuel installations on the Cambodian mainland while Marines landed by helicopter on an offshore island to rescue the crew. The 39 captives were retrieved, but the operation cost the lives of 41 U.S. military personnel. Nevertheless, the majority of the American people seemed to approve of the administration's decisive action.
