JAPANESE REFOCUS AFTER KHALKHYN GOL LOSS
Tokyo, Japan • May 11, 1939
Europe, the United States, and Japan, profiting from the technological, economic, social, and military advantages conferred on their countries by the Industrial Revolution, began placing weaker nations elsewhere in the world under their “protection.” The United States did that in 1898 when the Philippines became an American territory. Japan declared Korea, lying across the Sea of Japan, a protectorate in 1905 and five years later annexed the country (see map below).
Japanese militarism and aggressive trade policies on the Chinese mainland in the early twentieth century led Japan to garrison “advisors” there in the 1920s. Japanese troops based at Mukden (today’s Shenyang) in Northern China staged a bomb attack (allegedly by Chinese dissidents) on a Japanese-owned railroad, and the “Mukden Incident” of September 18, 1931, was the ruse for seizing the quasi-independent Chinese province of Manchuria, which bordered Korea on the east and, on the west, Outer Mongolia (or the Mongolian People’s Republic as it was known at the time), a satellite state of the Soviet Union. The Japanese creation of Manchukuo (State of the Manchus) became the launch pad for more Japanese land grabs in the 1930s.
On this date, May 11, 1939, a fierce undeclared war on the Mongolian plains broke out between Japanese forces from Manchukuo and Red Army forces stationed in Outer Mongolia. Although the Battle of Khalkhyn Gol (May 11 to September 16, 1939) is little-known in the West, it had profound implications on the conduct of World War II in Asia and Europe. Khalkhyn Gol (also spelled Khalkhin or Khalkin Gol) may be said to be the first decisive battle of the Second World War: it determined that Japan and Germany, the two principle Axis powers bound together in a full-blooded military alliance (the Tripartite Treaty signed in Berlin on September 22, 1940), would never geographically link up their areas of control through the Soviet Union.
Japan’s defeat at the Battle of Khalkhyn Gol convinced the Imperial General Staff, which held a stranglehold over successive Japanese civilian governments, that seizing Soviet resources in Northeast Asia was not tenable. Instead, the rich resources of Southeast Asia, especially the petroleum- and mineral-rich Dutch East Indies (present-day Indonesia), looked more and more appealing, leading directly to the attack on the Philippines, the Dutch East Indies, British Malaya, and the American possession of Hawaii on December 7 and 8, 1941.
The Battle of Khalkhyn Gol: Japan versus the Soviet Union, 1939
Left: Fought within an isolated 35 by 20 mile section of land, the fierce four-month conflict was named after the river Khalkhyn Gol, which flows through the battlefield. In Japan the conflict is known as the “Nomonhan Incident,” named after a nearby village on the border between Mongolia and Manchukuo (Manchuria). The preponderance of strength in the conflict lay with the armed forces of the Soviet Union and Mongolian Peoples Republic: As many as 74,000 soldiers versus half that number for the Japanese. In tanks, the combined Soviet-Mongolian forces held over a 7-to-1 advantage, in artillery pieces over a 3-to-1 advantage, and in aircraft over a 2-to-1 advantage. Manpower and equipment losses favored the Japanese.

After the occupation of Korea (1905) and Manchuria (1931), Japan’s military leaders in China focused expansionist aims on Soviet territories in Northeast Asia, and conflicts occurred frequently on the Manchurian border, in fact as early as mid-1929. The army’s aggressive plans sometimes caught the civilian government in Tokyo by surprise, as the 1931 “Muden Incident” (also known as the “Manchurian Incident”) showed.

The rapid defeat of Japan’s Kwantung Army, as its army in Manchukuo was called, was a significant factor in Japan’s surrender. Japanese leaders imagined the Red Army as poised to invade the Home Islands with boots on the ground, while the Americans were viewed as perfectly content to incinerate the Home Islands using their fleet of heavy bombers.
