Once again zur Frage (on the question) of Krichevsky. G. V. says that in the Paris colony it was stubbornly maintained that this Boris Krichevsky had received a letter of thanks from Millerand (for his contributions to Vorwärts) and that he had at one time even boasted about it. So now that a polemic has started between Vorwärts and Zarya and the question has been put point-blank, it is necessary to exert at once every effort to make a most thorough investigation (trial “by ordeal”) of the affair. Please tackle the matter at once. Collect evidence from all witnesses, both those who saw something and those who heard about it, and having done so, write us giving the names of all these witnesses and their testimony. As a last resort you should turn to Petit, though it would be better not to “scare the quarry” but to catch them before they suspect attack.
And so, to work! With full force!
Awaiting your reply,
 Vorwärts—a daily, central organ of the German Social-Democratic Party, published in Berlin since 1891. In the late nineties, after the death of Engels, it fell into the bands of the Right wing of the party and regularly printed articles by opportunists. Giving a tendentious picture of the struggle against opportunism and revisionism in the R.S.D.L.P., it supported the Economists, and later, after the split in the Party, the Mensheviks.
 The polemic referred to was between the editors of Vorwärts, Central Organ of the German Social-Democratic Party, Karl Kautsky, and Zarya over the article “The Lübeck Parteitag of German Social-Democracy” by Martov (Ignotus) in Zarya No. 2–3, December 1901.
