Q. How did the Allies deliver the Moscow Declaration to the Nazis?
Without formal diplomatic channels for a direct communiqué, the Western Allies delivered the message indirectly, while the Soviets found a more direct method of delivery...
- The Western allied powers published the declarations in the public press;
- The Soviets acted on the Moscow Declarations immediately by conducting the Kharkov Trial in which three war criminals (and one Russian traitor) were publicly tried and executed.
The Western allied powers published the declaration in the public press (freely available to Axis spies in the UK and the US who could then easily transmit this back to their contacts in the Third Reich). The Axis powers also monitored the Allied news reports to glean intelligence from them (newspapers and newsreels were available through foreign offices and agents in neutral nations as well as embedded in the US and UK).

The tribunal heard the case against four defendants, one Soviet collaborator and three Germans, members of the Wehrmacht, police, and SS forces, respectively. They were charged both under the Soviet and international law, the Moscow Declarations. The defendants were accused in participating in the murders of Soviet citizens, while the collaborator was charged with treason. [emphasis added]
The National Library of Australia includes this archived news report from The Argus (Melbourne, Vic. : 1848 - 1957), Tue 21 Dec 1943, Page 12, RUSSIANS SEE HANGING OF TORTURERS, covering the trial and hangings:
Before a crowd of 40,000 the 3 Germans and one Russian, who were convicted by a military tribunal of having taken part in mass extermination of Soviet citizens, were hanged in the snow-covered public square in Kharkov yesterday.
The condemned men were Reinhardt Retzlav, 36, of the German field police; Hans Ritz, 24, formerly assistant commander of Gestapo in Kharkov; Capt Wilhelm Langheld, 52, of the German military secret service; and Michel Bulanov, a Russian who served the Germans as a motor-driver.
Foreign correspondents who had been flown from Moscow to see the conclusion of the trial, saw the execution...
