"being so tried by artists and smiths, the iron masters and iron-mongers were all silenced until the 21st year of King James's reign". Later Furnaces However, this favourable report on his iron did not prevent him being "outed of his works and inventions ... by the Iron-masters and others wrongfully". This certainly applies to his second furnace, at Himley, which his father let this to Richard Foley in 1625, and may well apply to Cradley, which was later in Foley's hands. Afterwards he built a new furnace, Hasco or Hascod Furnace, near what is now Askew Bridge at Gornal. Dudley was economical with the truth. Hasco furnace was built in 1626, but in November 1627 he let it to Roger Hill, who assigned it to Foley. After Foley had used it for nine months he heard that Lord Dudley was claiming it and "durst not bring any stock" there, but continued to pay the rent. Dudd and Foley had an oral agreement for the supply of ironstone, but Lord Dudley discharged the workmen from the mines, and stopped Foley's horses carrying the ironstone until Foley paid for it (again) to Lord Dudley. Ultimately, his father 'entered' the furnace in 1631, and cut the dam. The bellows were probably cut without Lord Dudley's approval, but his re-entry to forfeit the lease was lawful and thus not a riot. After ironmaking Dudley "claimed" the manor of Himley, because his father had at one point put this in his name, probably to avoid it being seized by his creditors. This led to Chancery proceedings, which he lost, spending a time in prison for contempt of court. He obtained a new patent in 1638 for smelting metals with pitcoal, but was probably unable to exploit it. Of this period, he wrote: Civil War He served as an army officer in the Bishops War and on the Royalist side throughout the English Civil War. He served as a colonel in the Royalist Army and was general of the ordnance to Prince Maurice, and then Lord Astley. He may have supervised the modernisation of the Worcester City defences in time for the aborted siege of 1643, and was taken prisoner at the end of the Siege of Worcester in 1646. In 1648, he and others were captured by Andrew Yarranton (a Parliamentary captain) in "Bosco Bello" (Boscobel) woods, while they were planning a Royalist rising to
