It’s October 1968, and the Soviet Union has just landed cosmonauts on the moon. Warsaw Pact troops are massing on the Austrian border, and a nuclear showdown looms between east and west.

This scenario never happened — except in planning exercises by British civil servants, who meticulously rehearsed how they would govern Britain in the days before, and after, World War III. The details are included in the “War Book,” a secret Cold War manual declassified this month for the first time.

The book, which featured the doomsday scenario in a 1970 version, is a step-by-step guide for dealing with a crisis, from the first stages of conflict to “R hour,” the designation for the release of all Britain’s nuclear weapons.

“It’s a manual of how to go to war,” William Spencer, military history specialist at Britain’s National Archives, said Tuesday.

“It’s a technical manual in a way, for the people who needed to know,” he added. “But it could be seen as a horrific document for some people.”

Britain became a nuclear power in 1952 and British politicians were under no illusions about the devastating effects of nuclear war. A 1955 report, kept secret until 2002, estimated that an attack by Soviet hydrogen bombs would kill 12 million people instantly.

So every two years during much of the Cold War, British civil servants participated in a dry run for the end of the world, practicing how they would do everything from crack down on subversives to evacuate art treasures from London.

The exercises, played out over weeks, included daily mock news briefings from intelligence chiefs. Senior civil servants played the prime minister and Cabinet, deciding how to respond.

The 1968 exercise, revealed in the newly released manual, imagined Soviets landing on the moon as tensions mounted along the Iron Curtain. Day by day, the crisis escalated: Soviet troops invaded Austria, West Germany, Finland, Turkey, Greece and Italy, eventually invading “Danish islands.” Britons got more and more nervous — first writing letters to newspapers, then staying home from work, stocking up on food and buying supplies to build bomb shelters.

In calm bureaucratic language — loaded with code words to render the book meaningless to those not in the know — the document describes how as the crisis worsened, civil servants would introduce censorship, evacuate all but the sickest patients from hospitals and eventually be sent to one of 12 underground bunkers scattered around the country.

Britain was to be governed from these bunkers after a nuclear attack, with officials exercising powers of martial law over the remaining population.

Peter Hennessy, a historian who has studied the book and pushed for its release, said it provided a glimpse into “one of the darker bits of the British secret state in the Cold War.”

“The surprise really is the width and magnitude of it — 16 chapters to get the nation from a peacetime footing to a total war footing. It is a remarkable enterprise,” he told the BBC.

“When you consider where this road of decision-taking is leading to, it’s the end of the world. There’s no other way of looking at it. You would expect it to be cold print, coldly analytical, but this is sheer hell, really, the thought of it.”

Retired senior civil servant David Omand said he played the prime minister in one planning exercise and recalled the experience as “quite scary.”

“It just gives you a sense of humility that we expect our political leaders to take that kind of responsibility,” he told the BBC.

He told the broadcaster about what he called his “favorite measure” — the introduction of censorship for private correspondence — saying it “always aroused a lot of debate when we played these exercises.”

The document is the latest in a chilling series of Cold War artifacts that have recently been made public. In October, the National Archives released the scripts of statements the government planned to broadcast over the BBC in the event of nuclear war in the 1970s.
“This is the wartime broadcasting service,” the announcement began. “This country has been attacked with nuclear weapons.”

The government’s first “War Book” was created in 1911, and it was updated regularly as warfare and the threats to Britain changed. Its contents were top secret — Spencer said only 96 copies were made of the 1964 book.

It’s not known how many copies were made of the 1970 version. Parts of it were published in 2000, but the whole book was only released by the National Archives this month. Later versions remain classified.

The government no longer plans for war with the Soviet Union, which collapsed in 1991, but it still keeps a “War Book” and rehearses for disasters such as a major terrorist attack.
A Cabinet Office spokesman would give no details of the current plans, saying only that there are “lots of contingency plans to deal with lots of different crises we face today.”

Russia recently declared it is going to send a group of warships to Cuba, its cold war ally, in its latest defiant naval move around US waters, part of a drive to revive old Cold War ties with Latin America.

The warships will visit Havana on December 19-23, the navy said, continuing a tour that has already taken in US foes Venezuela and Nicaragua and seen the ships pass through the Panama Canal for the first time since World War II.

“This will be the first visit to Cuba by Russian warships since the Soviet era,” the Russian naval headquarters said in a statement.

The destroyer Admiral Chabanenko and two other ships already held exercises with Venezuela’s navy in the Caribbean Sea last month.

The naval manoeuvres close to US waters are seen as a riposte to Washington’s own moves in Russia’s Soviet-era sphere of influence, including in the Black Sea.

US officials have said they see no military threat from Russia’s naval manoeuvres but continue to keep a close eye on the situation.

The naval visit to Cuba, scene of a dramatic 1962 stand-off between Moscow and Washington over nuclear missiles, comes as tensions over US missile defence plans in eastern Europe have prompted talk of a renewed Cold War among some analysts.

Last month Russian President Dmitry Medvedev made a tour of Latin America where he visited Cuba and Venezuela and met former Cuban leader Fidel Castro, part of efforts to revive what he called “privileged relations” from Soviet times.

Last week he also received Argentinian President Cristina Kirchner, another Latin American critic of the United States.

Nicaragua’s leftist President Daniel Ortega is to visit Moscow on Thursday, after he risked Washington’s wrath this summer by following Russia in recognizing two Moscow-backed rebel regions of Georgia as independent.

The Russian moves in Central and Latin America follow heightened tensions over Russia’s military onslaught in Georgia, a close US ally.

Russia strongly objected to US naval deployments off Georgia’s Black Sea coast, accusing the United States of covertly rearming Georgia, a charge Washington denied.

On Monday the Russian navy avoided direct reference to the United States, saying that visits to Nicaragua, Panama and Venezuela signified “long-term prospects for developing cooperation among these countries’ navies in the interest of building stability and trust on the world’s oceans.”

During the Cuba visit, residents will be welcomed aboard the Russian ships and Russian officers will lay flowers at a memorial to Cuban campaigner for independence and critic of US expansionism Jose Marti, the navy said.

Last week the navy said it was sending ships from its Pacific Fleet to join ships from the Northern Fleet for exercises with India’s navy and in parallel would continue anti-piracy operations off Somalia.

Despite the growing Russian assertiveness, defence experts have said Russia’s navy remains severely weakened following years of post-Soviet neglect.

That impression was reinforced by the inadvertent fatal poisoning last month of 20 people aboard a Russian nuclear-powered submarine that was undergoing tests off the Pacific coast.
