<P> A fictionalized version of the incident was used by Dennis Potter for his TV play A Beast With Two Backs . </P> <P> Exploitation of the Forest of Dean Coalfield developed rapidly in the early 19th century with increased demand from local ironworks, and when some of the earliest tramroads in the UK were built here to transport coal to local ports the area was transformed by the growth of mining and the production of iron and steel . </P> <P> In 1818--19 David Mushet built Darkhill Ironworks, where he experimented with iron and steel making . In 1845, his youngest son, Robert Forester Mushet, took over its management . He perfected the Bessemer Process by solving the quality problems which beset the process . In a second key advance in metallurgy he invented Mushet steel (R.M.S.) in 1868 . It was the first true tool steel and the first air - hardening steel . It revolutionised the design of machine tools and the progress of industrial metalworking, and was the forerunner of High speed steel . The remains of Darkhill are preserved as an Industrial Archaeological Site of International Importance and are open to the public . </P> <P> Cinderford was laid out as a planned town in the mid-19th century, but the characteristic form of settlement remained the sprawling hamlets of haphazardly placed cottages . Characteristics shared with other British coalfields, such as a devotion to sport, the central role of miners' clubs, and the formation of brass bands, created a distinct community identity . </P>
