Such continued to be the state of things until the Restoration, when we find Dud Dudley a petitioner to the king for the renewal of his patent. He was also a petitioner for compensation in respect of the heavy losses he had sustained during the civil wars. The king was besieged by crowds of applicants of a similar sort, but Dudley was no more successful than the others. He failed in obtaining the renewal of his patent. Another applicant for the like privilege, probably having greater interest at court, proved more successful. Colonel Proger and three others[14] were granted a patent to make iron with coal; but Dudley knew the secret, which the new patentees did not; and their patent came to nothing. Dudley continued to address the king in importunate petitions, asking to be restored to his former offices of Serjeant-at-arms, Lieutenant of Ordnance, and Surveyor of the Mews or Armoury. He also petitioned to be appointed Master of the Charter House in Smithfield, professing himself willing to take anything, or hold any living.[15] We find him sending in two petitions to a similar effect in June, 1660; and a third shortly after. The result was, that he was reappointed to the office of Serjeant-at-Arms; but the Mastership of the Charter-House was not disposed of until 1662, when it fell to the lot of one Thomas Watson.[16] In 1661, we find a patent granted to Wm. Chamberlaine and--Dudley, Esq., for the sole use of their new invention of plating steel, &c., and tinning the said plates; but whether Dud Dudley was the person referred to, we are unable precisely to determine. A few years later, he seems to have succeeded in obtaining the means of prosecuting his original invention; for in his Metallum Martis, published in 1665, he describes himself as living at Green's Lodge, in Staffordshire; and he says that near it are four forges, Green's Forge, Swin Forge, Heath Forge, and Cradley Forge, where he practises his "perfect invention." These forges, he adds, "have barred all or most part of their iron with pit-coal since the authors first invention In 1618, which hath preserved much wood. In these four, besides many other forges, do the like [sic ]; yet the author hath had no benefit thereby to this present." From that time forward, Dud becomes lost to sight. He seems eventually to have retired to St. Helen's in Worcestershire, where he died in 1684, in the 85th year of his age. He was buried in the parish church there, and a monument, now destroyed, was erected to his memory, bearing the inscription partly set forth underneath.[17] [1] As late as 1790, long after the monopoly of the foreign merchants had been abolished, Pennant says, "The present Steelyard is the great repository of imported iron, which furnishes our metropolis with that necessary material. The quantity of bars that fills the yards and warehouses of this quarter strikes with astonishment the most indifferent beholder."--PENNANT, Account of London, 309.
