It is claimed from several sources that Churchill though he was never aware of the Tabun-B project was deeply disturbed on the basis of intelligence about German work on the Atom bomb in 1944. As V-1s started raining down over London in late July 1944 he conveyed to Hitler [possibly through Roumanian opposition factions in contact with Marshall Antonescu], that Britain would retaliate with Anthrax unless Germany abandoned it's development of nuclear weapons. USA sent a similar threat to use nuclear weapons on Germany unless Hilter sued for peace within 6 weeks.

Borkin writes about a letter from Dr Paul Harteck after the war confirming this threat. It is also recorded that scientists at Farm Hall discussed this threat too, however other sources include David Irving's Virus House (extracted by Irving from the Goudsmitt Papers) and is cited in the book: Germany and the Second World War: Organization and Mobilisation of the German sphere of Power..., Volume 5, Part 1, by Bernhard Kroener, Rolf-Dieter Müller, Hans Umbreit, Oxford Uni Press 2003
