Beijing, ten minutes past midnight, October 3, 1950.

Zhou Enlai called in K. M. Panikkar, India's ambassador to the People's Republic. The hour comes from the British chargé d'affaires in Peking. The next day Clubb, director of the State Department's Office of Chinese Affairs, read the full British text and made a point of noting it: a summons at that hour indicated urgency.

In the Chinese record of the conversation, Zhou's key sentence is short. American forces were trying to cross the 38th parallel and widen the war, and "we will take a hand" (我们要管).

Panikkar warned him that time was short. American troops might cross very soon, while the Indian government would need eighteen hours after receiving his telegram to act effectively.

"That is the Americans' affair," Zhou replied. Tonight's talk, he said, was to convey China's position on one question raised in Nehru's letter.

That sentence now had a long way to travel: Beijing, New Delhi, London, Washington.

On the morning it reached Washington, most of the officials around one conference table were inclined to read it as a bluff.

And on that same night, Beijing had not yet made up its own mind.

I. Two Telegrams

Go back one day.

On October 1, Beijing celebrated the first anniversary of the People's Republic. That same day South Korean troops crossed the 38th parallel. According to the Chronicle of Mao Zedong, Stalin cabled that day asking China to send at least five or six divisions to the parallel at once.

At two in the morning on October 2, Mao drafted a Central Military Commission telegram: Gao Gang was to leave for Beijing as soon as he received it, and Deng Hua was to have the frontier force finish its preparations early and stand ready to move.

The same day Mao drafted a long telegram to Stalin.

It opened with a conclusion. China had decided to send part of its army into Korea under the name of volunteers. Twelve divisions already moved to southern Manchuria would begin moving on October 15. They would fight defensively at first, then, once Soviet weapons arrived, counterattack together with the Korean comrades.

The arithmetic was precise. An American corps had some fifteen hundred guns of seven to twenty-four centimeters' caliber; a Chinese corps had thirty-six. The air force China had just begun to train would not have three hundred aircraft ready for combat until February 1951.

That telegram was never sent.

The Chronicle's editors explain in a note that it was meant to go to Stalin after a meeting decided to intervene. At that day's Secretariat meeting, however, most participants opposed sending troops, and the telegram was shelved. The meeting called an enlarged Politburo session for October 4.

The telegram that actually reached Stalin was a different one.

II. Roshchin's "Preliminary Telegram"

On October 3 the Soviet ambassador, Roshchin, sent a top-priority cipher telegram from Beijing relaying Mao's answer to Stalin's message of October 1. The Second Main Administration of the Soviet General Staff logged it as received at 12:15.

In the Russian transcription and the published English translation, Mao's answer ran roughly as follows.

We originally planned to move several volunteer divisions into North Korea when the enemy advanced north of the 38th parallel. Having thought it over thoroughly, we now consider that this could have extremely serious consequences.

First, a few divisions could hardly resolve the Korean question. Our troops are extremely poorly equipped, there is no confidence of success against American troops, and the enemy could force us to retreat.

Second, it would most likely provoke open conflict between the United States and China, drag the Soviet Union into war, and make the question extremely large. Many comrades in the Central Committee judged that caution was necessary.

It was better, therefore, to show patience now, refrain from advancing troops, and actively prepare forces. Korea, temporarily defeated, would turn to partisan war.

A final decision had not been taken, the telegram said. This was a preliminary message for consultation. If Stalin agreed, Zhou Enlai and Lin Biao could fly at once to his vacation place to talk it over.

Roshchin added his own judgment. The answer showed a change in the Chinese leadership's original position. In conversations with Yudin, Kotov, Konnov, and Roshchin himself, Mao and Liu Shaoqi had repeatedly said the people and the army were ready to help Korea, that the army's fighting spirit was high, and that it could defeat American troops if necessary, regarding them as weaker than the Japanese.

The reasons for the change, Roshchin wrote, "are not yet clear to us." He offered guesses: the international situation, the worsening position in Korea, and the work of the Anglo-American bloc through Nehru, who had urged China toward patience and restraint.

So that night produced two pictures.

At midnight, Zhou told the Indian ambassador "we will take a hand." At almost the same time, an answer bound for Moscow said China would not send troops for now.

The two statements need not cancel each other. One drew a line for outsiders; the other admitted, inside the alliance, that nothing was settled. But no outsider at the time could see both documents. Roshchin's telegram did not mention Panikkar at all, and Washington could not see what Mao had written to Stalin.

III. Washington's Morning

London, 11 a.m., October 3. The American chargé, Holmes, sent urgent telegram 1934. The Foreign Office had just received a telegram from Peking: Zhou had called in Panikkar and told him that if UN armed forces crossed the 38th parallel, China would send troops across the frontier to take part in the defense of North Korea. That would not happen if only South Koreans crossed.

The State Department logged it at 5:35 a.m. Washington time.

At 10:30 a.m., Deputy Assistant Secretary Merchant sent Dean Rusk a status report.

At 8:30, at the Department's request, Defense had relayed the message to General MacArthur for information. The watch officer had repeated it to the delegation in New York. At noon it would go to the President with his batch of important telegrams.

Another report was waiting to be checked. An AP radio item that morning described a hundred-mile column, artillery included, stretching from Manchuria across the Yalu into North Korea. The Department sent an urgent query to Tokyo; the morning teleconference had nothing on the point.

At the 9:30 meeting of Acting Secretary Webb, Merchant argued that the message should be treated with extreme seriousness and not discounted as a bluff. He was also worried that MacArthur's outstanding orders were unclear in these circumstances.

His impression was that the majority present were inclined to regard it as a bluff pending more information. They agreed to await confirmation from New Delhi and more on the column before sending an evaluation to the President.

The same day Johnson, deputy director of the Office of Northeast Asian Affairs, wrote that Zhou's statement "undoubtedly contains a large element of bluff," aimed at forestalling decisive UN action on the British resolution, but that it could not be assumed to be entirely bluff.

He seized on the exception. If Beijing said a South Korean crossing would not count, why not explore using South Korean forces alone in the North, with American logistic, air, and naval support continuing?

In Moscow, Ambassador Kirk was surprised by something else: why had a message this serious come through the Indian ambassador rather than directly to the UN or the United States? The British embassy shared his speculation that it might be a last-minute Chinese attempt to play on Indian apprehension and salvage maximum profit for China and the USSR from North Korea's reverses.

IV. Three Telegrams in New Delhi

New Delhi, 7 p.m. Ambassador Loy Henderson reported that the British High Commissioner, Nye, had just told him what Bajpai, Secretary General of India's Ministry of External Affairs, had said late that afternoon: a telegram had just come from Panikkar. Zhou had told the ambassador that Peking had decided to intervene in Korea if US forces entered North Korea.

Nehru was in Lucknow. Bajpai took it on himself to pass the information to the British so that London and Washington would know, and so that the United States and MacArthur would realize how grave the situation was.

Panikkar's comment was a single line: he was convinced the Chinese decision was final.

The next morning, on instructions, Henderson called on Bajpai.

At first Bajpai read only excerpts. He did not want to hand the full text to the American government, he said, because remarks by Chinese leaders derogatory to the United States might widen the breach that India was trying to narrow. In the end he let Henderson read all three telegrams.

The Beijing position they relayed was sharper than London's summary. If UN forces entered North Korea, Peking must consider it aggression against a friendly neighboring state and would meet it with armed force. Unless the Korean conflict was considered a civil war from the start, crossing the parallel from the south was aggression. It was hypocrisy for the United States to call the North's entry into the South aggression but not the UN's entry into the North.

A further telegram that morning added that South Korean forces entering North Korea would not be considered aggression and would not require Chinese intervention. Entry by any other forces would be met by Chinese intervention.

Bajpai also read aloud Nehru's message of several days earlier appealing to Zhou not to intervene. Henderson noticed that he obviously skipped several passages.

V. "Cannot Safely Be Regarded as Mere Bluff"

On October 4 Clubb wrote his memorandum.

From the full British text he picked out three points: the summons at 0010; Zhou's reference to "American" armed forces crossing the parallel; and Zhou's statement that China would accept no settlement of the Korean question to which it was not a party.

His judgment: the démarche "cannot safely be regarded as mere bluff," and must be regarded as made with the foreknowledge and support of the USSR. If China and the Soviet Union were prepared now to risk a clash with the UN in Korea, they were prepared to risk World War III.

Deputy Under Secretary H. Freeman Matthews underlined "USSR" and "prepared to risk the danger of World War III" and put a question mark in the margin.

Clubb, too, noted the exception: South Korean forces might first be tried alone north of the parallel. It would cost little as an experiment, he wrote, but strong hopes should not be attached to it.

On October 5 the Department sent a circular to missions including Belgrade, Stockholm, Taipei, and Hong Kong, asking them to report at once anything that might shed light on Chinese or Soviet intentions to intervene militarily. Its last line: no attribution should be made to the source.

VI. Beijing Decides

While Washington canvassed its embassies, Beijing was arguing.

According to the Chronicle, at the enlarged Politburo meeting on the afternoon of October 4, Mao first asked participants to set out the disadvantages of intervention. The reasons came one after another: after so many years of war the country urgently needed to heal; the state was only a year old and its economy in great difficulty; land reform had not yet begun in the newly liberated areas, and bandits and agents had not been eliminated; the army was poorly equipped and had neither air nor naval superiority.

Mao said, as the Chronicle records it: "Everything you say has its reasons. But when another country is in a moment of crisis and we stand by watching, however we put it, we will feel bad about it."

The meeting resumed on the afternoon of October 5. Peng Dehuai said that sending troops was necessary. The meeting adopted the decision to "resist America, aid Korea, protect the home, defend the country," chose Peng to lead the volunteers, and decided to send Zhou and Lin Biao to the Soviet Union to talk with Stalin.

On October 7 the UN General Assembly adopted its Korea resolution; that same day, according to the Chronicle, US-led UN forces crossed the 38th parallel.

On October 8 Mao issued the order renaming the Northeast Frontier Force the Chinese People's Volunteers and appointing Peng Dehuai commander and political commissar. Roshchin received Mao's telegram to Stalin at 10:30 that night, Peking time, and relayed it: the troops might begin entering Korea around October 15; Zhou and Lin had taken off at eight that morning.

On October 13, with Zhou still in the Soviet Union, the Politburo met again. The Chronicle records that participants agreed unanimously that even without Soviet air support, with American forces pushing north in strength, China should still send troops.

"We will take a hand" had only now become a settled decision.

VII. Wake Island

On October 12 the CIA produced an estimate titled "Threat of Full Chinese Communist Intervention in Korea."

Its conclusion was plain. Despite statements by Zhou Enlai, troop movements to Manchuria, and propaganda, there were no convincing indications of an actual Chinese intention to resort to full-scale intervention. Barring a Soviet decision for global war, such action was "not probable in 1950." It added that from a military standpoint the most favorable time for intervention had passed.

The estimate went into a briefing book prepared under Rusk's direction for the Wake Island conference, with copies sent to the White House and the other participants.

At 7:36 a.m. on October 15, Truman and MacArthur opened their conference on Wake Island in the Pacific. According to the record compiled by General Omar Bradley from notes kept by the conferees, the President asked about the chances of Chinese or Soviet interference.

"Very little," MacArthur answered. Had they interfered in the first or second month, it would have been decisive; we are no longer fearful of their intervention. The Chinese had 300,000 men in Manchuria, of whom probably not more than 100,000 to 125,000 were along the Yalu, and only 50,000 to 60,000 could be gotten across. They had no air force. If the Chinese tried to get down to Pyongyang, there would be "the greatest slaughter."

VIII. Crossing at Dusk

On October 18, with Zhou back in Beijing, the Politburo met once more. According to the Chronicle, Mao said the enemy was already besieging Pyongyang and in a few days would reach the Yalu; whatever the difficulties, the volunteers' crossing could not change again, nor be postponed.

At nine that evening he ordered the volunteer commanders to begin crossing the Yalu the next evening, the 19th, along the Andong and Ji'an lines. For strict secrecy, crossing units would start each day at dusk and stop at four the next morning, with everything concealed before five. Two or three divisions would cross on the first night.

At dawn on October 25 Mao cabled Peng Dehuai and Deng Hua a summary of what the other side had noticed. So far, among all the reports received, only an intelligence officer of the South Korean 6th Division had said that, according to refugees, sixty trucks carrying troops had moved from Sinuiju toward Changsong County on the nights of the 19th and 20th. Nothing else showed any awareness of the Chinese arrival. American commands in Pyongyang and Tokyo both believed they could reach the Yalu within a few days.

The warning was spoken at midnight so that it would be heard.

The crossing was made at night so that it would not be seen.

The first time, Beijing had not yet decided, yet spoke without hedging. The second time, the decision was made, and not a word announced it.

IX. Archives in Dialogue: Agreement, Conflict, Unknowns

Agreement: the Chinese record of the conversation, the telegrams relayed through India and Britain, and the State Department circular all make a crossing by American or UN forces the condition for Chinese action; both the Indian telegrams and the London report exclude a crossing by South Korean forces alone. Soviet archival records and the Chinese Chronicle both show that around October 2 the Chinese leadership had not settled the question and many members had doubts; the Chronicle dates the decision to October 5, and the Soviet record of October 8 shows intervention decided.

Conflict: the subject of the warning shifted in transmission. The Chinese record says "American forces"; Clubb, working from the British full text, stressed "American" armed forces; London's telegram 1934 says "UN armed forces"; Henderson's October 3 telegram says "US forces," his October 4 telegram "UN forces." On how to read the warning, Merchant and Clubb held it could not be dismissed as bluff, Johnson saw "a large element of bluff," most at Webb's meeting leaned toward bluff, and the CIA judged full-scale intervention "not probable."

Unknowns: these materials cannot establish whether Beijing's leaders already leaned one way when Zhou summoned Panikkar. The sequence and relationship of the two October 2 telegram texts rest here only on the Chronicle's note and the Soviet archival transcription. The AP report of a hundred-mile column is not confirmed in these American documents.
