Leicester Philip Sidney, Dictionary of National Biography… (1912)
“ Lord Penrhyn replied by closing the quarries, and an angry debate took place in the House of Commons. But Lord Penrhyn would abate none of his conditions, and the men capitulated. Lord Penrhyn as a champion of free labour refused to allow the intervention of outsiders in dealings with his men, and late in 1900 a second strike of great extent broke out. The quarries were again closed, but were re-opened after a prolonged stoppage with 600 of the former non-union workmen. Penrhyn refused to re-engage the ringleaders of the agitation or to recognise any trades union officials. ”
