While in prison, Wilde wrote Douglas a long and critical letter titled "De Profundis", describing exactly what he felt about him, which Wilde was not permitted to send, but which may or may not have been sent to Douglas after Wilde's release: it was given to Robbie Ross, with the instructions to make a copy and send the original to Lord Alfred Douglas. Lord Alfred Douglas later said that he received only a letter from Ross with a few choice quotes, and didn't know there was a letter until reference was made to it in a biography of Wilde's on which Ross consulted. Following Wilde's release (on 19 May 1897), the two reunited in August at Rouen, but stayed together only a few months owing to personal differences and the various pressures on them.
