Secret British-US nuclear plot to obliterate Russia EXPOSED in bombshell documents

Explosive documents have revealed a chilling British and American nuclear strike plan targeting Russia - just two years after World War Two ended.

The sensational files, discovered buried in the National Archives at Kew, West London, expose how Allied forces allegedly plotted a devastating pre-emptive atomic assault on Soviet positions across Germany and eastern Europe in 1946.

The jaw-dropping blueprint would have seen a staggering 400 Mosquito fighter-bombers - famously crafted from plywood - armed with nuclear weapons in a bid to crush Russian forces. The report comes as Paddy Mayne's emotional farewell letter to SAS demolishes TV fiction.

Swiss military intelligence, monitoring the escalating tensions between former wartime allies, compiled this explosive "annex" detailing what they claimed was the British and American masterplan to "paralyse the points of departure" of any Soviet offensive for up to 45 days.

The bombshell file, dismissed as "entirely fictitious" by Prime Minister Clement Attlee, surfaced during a top-secret parliamentary meeting in November 1946 involving Attlee and wartime hero Winston Churchill.

Churchill had been handed the classified document by a Swiss staff officer during his visit to Switzerland just weeks earlier, with full backing from the country's high command.

After revealing its contents, Churchill "emphasised most earnestly that knowledge of the contents of this paper should be limited to the smallest circle".

The Swiss intelligence report, stamped "top secret", boasted that "no foreign information service is in possession of any more accurate information than ourselves".

Their assessment painted a terrifying picture - Russian forces stationed across Germany, Austria, Hungary, Poland and the Baltic States totalled a crushing 130 divisions and 50 armoured brigades.

"This is certainly more than is necessary to overcome the resistance of the 25 Allied Divisions of occupation in Germany, of which 9 to 10 American Divisions are nothing but a police force," the Swiss warned.

Then came the most shocking revelation of all - detailed plans for a coordinated British-American nuclear blitz on Russian positions.

"It is true that recent information, emanating from superior British and American Officers indicates that measures are being taken to resist possible Soviet ambitions," the explosive document revealed.

The terrifying first phase would last just one day, featuring "Destruction of bridges, railway stations, railway tracks, nodal points on the main lines of communication in a Zone A, comprising the territory between the Elbe - Danube and the Vistula."

This devastating zone encompassed eastern Germany, Czechoslovakia, western Poland and chunks of Austria and Hungary.

Phase two would unleash three days of hell, with "Air effort would be concentrated on Poland (Zone B) whilst continuing tactical operations in Zone A."

At the heart of this nuclear nightmare would be 400 Mosquitos carrying up to 200 atomic bombs, backed by a terrifying armada of 4,000 heavy and medium bombers plus 1,200 fighter planes.

Reserve forces would include another 120 Mosquitos, 500 medium bombers, 500 heavy bombers and 1,000 fighters over four days of anticipated warfare.

"The American and British staffs reckon that this counter-action should have the effect of paralysing the points of departure of the Soviet offensive for a period of 30 to 45 days," the Swiss claimed.

"This delay would, in their judgement, suffice to allow forces to be brought up which would be capable of carrying out a defensive resistance. Later, it would be their intention to concentrate sufficient troops to beat back the Russian forces."

The Swiss correctly questioned whether "Anglo-American staffs are in a position to put the plan into execution", noting America would need to provide the bulk of resources and wouldn't be ready until June 1947.

Their chilling conclusion warned that Russian forces "still retain their relative superiority" and "that a conquest of Western Europe by the Soviet must be considered as a practical possibility".

However, Attlee furiously branded the alleged plans "entirely fictitious", insisting "No plans of this character had been worked out."

He argued it was "impossible" to deploy such massive forces because Allied resources were "tied up" across Greece, Palestine and Indonesia.

However, the Swiss assessment proved wildly inaccurate in one crucial respect - while they claimed 200 atomic bombs were available for the alleged operation, the harsh reality was that the US possessed just nine nuclear weapons in autumn 1946, with Britain having none at all.

It wouldn't be until 1949 that America would build up its nuclear arsenal to around 400 bombs - making the Swiss timeline physically impossible.

Churchill believed the deterrents to Russian attack were the "enormous latent strength" of Britain and America, plus US atomic capability.

The wartime leader wanted Britain to "have about 50 of these bombs", and if America wouldn't "let us have them", then "we ought to make them ourselves".

Attlee revealed the US were being "very difficult at the present time" - a reference to American opposition to Britain's nuclear ambitions.

Churchill later oversaw the UK's nuclear programme during his 1951-1955 premiership, culminating in Britain's first atomic bomb test in 1952.

These alleged 1946 Swiss intelligence reports were entirely separate from earlier wartime planning. The meeting occurred over a year after Churchill had previously commissioned Operation Unthinkable while Prime Minister.

The alleged 1946 plans bore little resemblance to Unthinkable's known details.

Brigadier Geoffrey Thompson led Unthinkable, which controversially involved re-arming defeated German troops.

Released National Archives files from 1998 revealed how Allied forces would launch a surprise assault on Stalin's armies from July 1, 1945, driving the Red Army back to the Oder and Neisse rivers, 55 miles east of Berlin.

This Western offensive would have been history's largest tank assault, deploying 8,000 armoured vehicles in a massive showdown in Soviet-occupied Pila, northwest Poland.

An estimated 47 Allied divisions - including 14 tank divisions - would be required, with 40 more held in reserve.

But Soviet forces boasted twice as many men and tanks.

Churchill's horrified military chiefs condemned the plan. Field Marshal Sir Alan Brooke warned Allied troops would be "committed to a protracted war against heavy odds."

General Ismay was disgusted by using Hitler's defeated forces, calling it "absolutely impossible for the leaders of democratic countries even to contemplate", arguing Russians had done the "lion's share of the fighting and endured untold suffering" against Hitler.

Field Marshal Brooke declared it "quite impossible" that Unthinkable would succeed, while Foreign Office chief Eden also opposed it.

Churchill's chiefs officially rejected the plan - as did America under Truman.

US military cables made clear there was no possibility Americans would lead efforts to drive Russian troops from Poland by force.

This lack of support delivered the killer blow to Unthinkable.

Ironically, America later developed their own equivalent in late 1946 - codenamed Pincher - but this bore little resemblance to the Swiss interpretation of Allied plans.
