In March 1984, twenty five years ago, the National Coal Board announced it intended to close 20 pits with the loss of 20,000 jobs. Cortonwood in South Yorkshire was earmarked as the first to close, “imminently”, in the words of the NCB chairman, Ian MacGregor. The miners at Cortonwood immediately came out on strike and by March 12th the National Union of Mineworkers had made the strike national. This was to become the bitterest industrial dispute in most of our lifetimes and marked a major defeat for the working class.
