The correspondence in the Sedov letters confirmed that a plot was underway against Stalin, with Trotsky communicating with his son about the existence of a Trotsky-Zinovievist faction of conspirators inside the party, with Trotsky allegedly stating, "Before everything else we have to drive out the present leadership and get rid of Stalin nothing but their liquidation can bring victory”. Curiously, later scholars who accessed this archive of all of Trotsky’s papers found this document was missing and allegations of a document purge were thrown around. It doesn’t help that the archive in question is at Harvard, after academics there bought all of Trotsky’s correspondence some time after his death. Broué wrote about it all.
What were these letters and what did they prove?

Thanks!
Also before he died he asked for his archive to be closed for forty years so Broue only discovered these in the 1980s
They were written in invisible ink too
Grover Furr has an outline here of the documents
