In 1969 , SDS split into different ideological factions and Weatherman emerged , its purpose being to build armed struggle amidst young white Americans in support of the Black Panthers and other militant groups and also oppose the war in Vietnam via activities intended to " Bring the War Home " . Gilbert joined this group in 1969 with his friend , Ted Gold , who later died in the March 1970 Greenwich Village townhouse explosion , along with fellow Weather members , Diana Oughton and Terry Robbins . The group became a clandestine operation , and the organization was renamed the Weather Underground . When Weather went underground , members often used money they already had or received from their family to fund their efforts . Gilbert cashed in his Israel bonds and half of that money went to supporting Weather and the other half was put into the Black Panther bail fund
