In response to the death of Black Panther members Fred Hampton and Mark Clark in December 1969 during a police raid, on May 21, 1970, the Weather Underground issued a "Declaration of War" against the United States government, using for the first time its new name, the "Weather Underground Organization" (WUO), adopting fake identities, and pursuing covert activities only. These initially included preparations for a bombing of a U.S. military non-commissioned officers' dance at Fort Dix, New Jersey, in what Brian Flanagan said had been intended to be "the most horrific hit the United States government had ever suffered on its territory".[78]
