Excerpts from Books and Wikipedia
"After 51 weeks, the National Union of Miners (NUM) finally called off its national strike. . . . But this could not disguise the scale of the defeat of the most powerful trade union in Britain, one that in 1974 had brought down the Conservative government. . . . The consequences of defeat were severe. Within 20 years an industry employing 187,000 miners was reduced to just 6 collieries, employing less than 4000." [Furtado: 1001 Days]
