The Menwith Hill Accountability Campaign seeks to build on the work previously undertaken by the Campaign for the Accountability of American Bases (CAAB).

CAAB evolved in 1992 out of the long campaign of protest at the American base at Menwith Hill, near Harrogate, North Yorkshire; local people having expressed their concerns at the arrival of the US Army at Menwith Hill in 1951. We have continued to build on the work and struggles of many people over the years since the arrival, occupation and control of the US Visiting Forces in the UK.
