In 1940, during the darkest hours of the Second World War, an extensive area of Welsh land was seized to be used as a firing range. 54 families were forced to leave Epynt at short notice, and a civilized community, Welsh in language, was dispersed in a few months. This was a tragedy, but equally tragic is that there remains so much ignorance about the evictions which occurred. This volume records some of the more important chapters in the history of the mountain and its people and, in particular, the events of 1939 and 1940.
