I am sending you a copy of a letter which was found in the archives. The sheet was in a “confidential” dossier with various other things. The letter, of which I have made an exact copy for you, bears neither a date nor the name of the person to whom it is addressed. It is an original, rather badly typed: it seems likely to be a copy made from a manuscript letter. Here are some indications which my uncle has dictated :
Would it be possible to recover the original? Naturally, before we receive information from you, we shall make no use of this document in connection with NY. 
NB Sedov wrote several notes by hand on this letter:
The allies must send us correspondence for the Bulletin. The editors of the Bulletin undertake to publish the documents of the allies. But it reserves the right to comment freely upon them.
As concerns the general situation in the country, the information does not differ much from the picture which I had formed from an attentive reading of the Russian newspapers.
The (...) is organised  it includes the Zinovievists, the Sten–Lominadze Group and the Trotskyists (former “...”).  The Safar–Tarkhan Group  have not yet formally entered they have too extreme a position; they will enter very soon. The declaration of Z. and K.  on the very grave mistake which they made in 1927 was made at the time of the negotiations with our people about the bloc, just before Z. and K. were deported.
The collapse of the I.N. (...)  Group, Preobrazh.  and Uf.  (these three groups formed part of the centre) was provoked by a sick, partly insane man. They arrested him by chance and he began to talk. They have certainly found no document in the homes of I.N. or the others that could be “Trotskyist literature”. Some days before I.N. was arrested, he told our informant: “X. has betrayed and I am expecting to be arrested from one day to the next.” Thanks to the presence of his Markovkin , who had provided him with all the information, he was prepared. Unfortunately I.N. did not have time to pass it on. 
The informant says that there was no weak point whatever coming from abroad or in general connected with abroad. 
The collapse of the “old men” is a heavy blow , but the links with the workers have been preserved ...
1. Library of Harvard College 13905 with the permission of the college. The original is in French.
2. “My uncle” meaning Trotsky
3. Leon Sedov at Berlin
4. E.S. Holtzmann
5. The Menshevik paper, Sotsialistitcheskii Vestnik (Socialist Courier) then published in Berlin and edited by Boris Nikolaievsky.
6. What the Menshevik paper called a declaration of eighteen Bolsheviks seems to have been the platform of Ryutin.
7. New York which was where the Dewey Commission was examining the two Moscow Trials.
8. Library of Harvard College 13905c and 1010, with the permission of the college. Translated from the German by Alain Calvié. This document is not dated, the two examples we have seen are the same, both copies. It seems that Sedov was unable to find the original.
9. This is about a circular to the Russian Bolshevik-Leninists that we do not have.
10. Kolokolnikov (from “Kolokol” the clock) was what Sedov called I.N. Smirnov
11. The source was E.S. Holtzmann, who had met Sedov and had passed on to him news and documents from Smirnov.
12. Cf. N.15, pp. 9–10. [What this note refers to is unclear! – Note by MIA]
13. See note 6 above.
14. Library of Harvard College 4782, with the permission of the college. Translated from the Russian by Isabelle Lombard. We only give an extract, the part that deals with the bloc. The rest deals with the “special journeys” in Russia and unwillingness of Sedov to leave Germany which was the wish of his father. We want to publish this in No. 6 of the Cahiers Léon Trotsky, whose theme is the Russian Left Opposition. The letter, written in citric acid and not dated is the only evidence of a reply to document no. 2. We have followed here the order of the discoveries.
15. The missing word has been cut out with scissors. It seems to be the word “bloc”
16. The missing word has been carefully erased. It seems to be “capitulators”.
17. This is about Safarove and Tarkhanov.
18. Z and K are obviously Zinoviev and Kamenev.
19. The missing word has been carefully erased. It seems to be “Smirnov”
22. Was this an individual? We have not identified him even if it could be about the policeman who informed Smirnov.
23. We do not know what this was about.
24. The word no has been underlined by Trotsky.
25. We do not know to whom this refers: Grünstein?
