The Chinese Communist Revolution, as presented in the account of 1949, was both the collapse of Chiang Kai-shek’s Nationalist regime and the establishment of a new Communist government. By spring, the Nationalists’ defeat was already treated as a foregone conclusion: a Communist army of a million men had crossed the Yangtze, moving into the last provinces still loyal to Chiang. The revolution’s official culmination came on October 1, when the People’s Republic of China was inaugurated in Peking. For the United States, the outcome became not only a major international reversal but a fierce dispute over responsibility for China’s defeat.

The Nationalist collapse

The military and political deterioration had been building for years. The account recalls that George Marshall had already reported on the likely outcome after his unsuccessful year in China in 1946. By 1949, Chiang’s regime was crumbling before the Communist advance. An American military adviser argued that only direct participation by United States troops could change the military situation, but also reported that Nationalist defeats did not result from shortages of ammunition or equipment. In his assessment, poor leadership, corruption, and dishonesty within the armed forces explained the defeats. The distinction mattered: the crisis could not be reduced to a lack of American matériel.

In April 1949, the crossing of the Yangtze made the scale of the reversal unmistakable. The Communist army advanced south into territory that remained under Nationalist control, and the fall of China, in the book’s account, had become virtually certain by spring. This was not described as a sudden outcome caused by one lost battle. It was the culmination of internal weakness and a sustained military advance, against a Nationalist government whose American support had not repaired its political and institutional failures.

American aid and the China White Paper

The United States had committed substantial resources to Chiang’s government. In the preface to a major report, Secretary of State Dean Acheson noted that since Japan’s surrender the United States had provided more than two billion dollars in money and arms to help the Nationalists resist communism. His explanation of the failure placed responsibility principally on the regime’s internal decay: corruption, weak leadership, and indifference to the aspirations of the Chinese people. American assistance, in this account, had tried to influence events but could not overcome those internal forces.

On August 4, President Harry S. Truman announced the release of the report, United States Relations with China: With Special Reference to the Period 1944–1949. It ran to 409 pages, with another 645 pages of appended documents. The administration presented it as a frank record of American policy, reaching back to the 1840s, and intended it to clarify what had happened before the Nationalist collapse was complete. Truman had asked for the report to be compiled in the hope that a documented account would explain the policy and steady public opinion.

The publication did not settle the argument. Truman had privately identified the Nationalist government’s corruption as a central cause and told Arthur Vandenberg that the United States had backed the wrong horse. But the report’s explanation—that the decisive forces were internal to China and beyond American control—met a public already strongly attached to the country and its wartime Nationalist allies. The administration’s attempt to account for the outcome instead gave the dispute a focus and made the report a lightning rod for accusations about American policy.

A domestic political controversy

The Nationalists’ impending defeat prompted alarm and recrimination across the United States. Critics associated with the China Lobby, including religious and patriotic organizations, prominent Republicans in Congress, and publisher Henry R. Luce, attacked the administration. Time and Life amplified concern that Communist power in Asia threatened a much larger portion of the world. For many Americans, the news collided with longstanding affection for China, shaped in part by missionary support and wartime alliance. The loss therefore carried an emotional and political weight that the administration’s detailed policy record could not dispel.

The China White Paper was intended as a palliative, but its publication instead inflamed the controversy. Some critics regarded it as a record of well-meaning mistakes; others accused the government of disguising responsibility or protecting officials. The revolution’s consequences thus reached beyond China: the Nationalist collapse became a domestic test of how the United States understood its influence, the limits of aid, and the causes of Communist victories. The official inauguration of the People’s Republic on October 1 confirmed the historic change, even as the American argument over how it had happened continued.
