Weatherman contained the vast majority of former SDS National Committee members, including Mark Rudd, David Gilbert and Bernardine Dohrn. The group, while small, was able to commandeer the mantle of SDS and all of its membership lists, but with Weatherman in charge there was little or no support from local branches or members of the organization,[25][26] and local chapters soon disbanded. At the War Council, the Weathermen had decided to close the SDS National Office, ending the major campus-based organization of the 1960s which at its peak was a mass organization with 100,000 members.[27]
