Parnell was conveyed to Kilmainham Gaol, where he joined several other prominent members of the Land League who had also protested against the Act and been jailed. There, together with William O'Brien, he enacted the No Rent Manifesto campaign. He was well aware that some in the Liberal Cabinet—in particular Joseph Chamberlain—were opposed to the mass internment of suspects then taking place across Ireland under the Irish Coercion Act. The repressions did not have the desired effect, with the result that Forster became isolated within the Cabinet, and coercion became increasingly unpopular with the Liberal Party.
