Who fought Japan — the Nationalists, the Communists, or neither as much as each claimed? And why does the answer still matter politically?

Map: Stalemate — Two Chinas at War — China in Revolution, 1911–1949 — 1944 · CHINA IN REVOLUTION, 1911–1949

For six years the front line barely moves, and the map’s stillness is the story. Study what the charcoal actually is: cities, railways and river valleys — a war of points and lines, as Japanese staff officers themselves called it. Between the lines, the occupation is a colander: Communist base areas metastasize across the north China countryside, and government guerrillas hold whole mountain ranges nominally behind the front. Japan garrisons a million men in China and rules, in any governing sense, only what a garrison can see. The blue interior — Free China — is huge, poor and besieged: the ◆ at Chungking marks the most-bombed city on earth to that date, where the government works in tunnels and does not surrender; the ◆ at Changsha marks what panic costs (a garrison fired its own city ahead of an enemy a hundred kilometers away — then held that same city against three Japanese offensives, the war’s stubborn hinge). The blue arrow through the mountains is the Burma Road (the ● at Lashio): 1,100 kilometers of hand-dug hairpins carrying Free China’s imports — cut in 1942 when the wider war (see Hong Kong, Burma and the Philippines go charcoal) closes every land route, replaced by the Hump airlift over the Himalaya at the cost of some 600 Allied aircraft. Geography is why China cannot be starved out; the price of geography is that almost nothing gets in.

THE SHORT ANSWER

Why the front froze. By late 1938 Japan had outrun the arithmetic of conquest: every advance lengthened railways that guerrillas cut and garrisons bled to guard, against an enemy who refused decisive battle by policy. Tokyo’s answer — blockade, puppet governments (Wang Jingwei’s defection to a collaborationist “National Government” at Nanjing in 1940 was its prize catch), and terror bombing of Chungking — was a theory that China would tire. China’s answer was to be too big and too poor to strangle. Both were right enough to freeze the map for six years.
Two ways to tax a war. The Nationalists financed total war from a truncated tax base with the tools of a modern state — paper money and procurement — and got hyperinflation, corruption and the loathing of everyone the requisition touched. The Communists financed insurgency from villages they lived in, with rent reduction, progressive levies and production drives — cheaper war, better politics. The divergence is not virtue but structure: one side had to run a state under bombardment; the other had to run a movement under occupation. The consequences compound into 1949.
Occupation as recruiting agent. Japan’s north China sweeps — the “three alls” of burn, kill, loot — depopulated whole belts (the base areas shrank terribly in 1941–42) and simultaneously proved the Communist case in every village they touched: the old order could not protect you; the party stayed and bled with you. Chalmers Johnson built his peasant-nationalism thesis on exactly this mechanism. Whatever its final weight (Chapter 12 argues it), the occupation was objectively the CCP’s best organizer.
The alliance of mutual disappointment. From 1942 China was a theater in someone else’s war: promised a seat among the Great Powers and delivered a trickle over the Hump; asked by Stilwell to spend armies in Burma while Ichigo bore down; audited by allies who compared a besieged, decaying state to their own unbombed economies. The Stilwell crisis of 1944 — Roosevelt demanding, then dropping, an American commander for China’s armies — marks the moment Washington began planning a postwar Asia that routed around Chiang. Alliances run on delivered power, not endured suffering.

THE TURN

Hengyang, June–August 1944. Choose the paradox deliberately: a heroic six-week defense, and the hinge is what its failure revealed. After Hengyang, Ichigo ran essentially unchecked — and everyone drawing conclusions (Washington, Yan’an, the Chinese public, Chiang’s own commanders) drew the same one: seven years of siege had hollowed the Nationalist state faster than it had hollowed the occupation. The campaign Japan designed to knock China out instead certified which China would be standing when Japan fell. Wars within wars are decided at moments like this, invisible on the day.

WHAT IT CHANGED

The verdict of 1944 shapes 1945–46. Ichigo left the Nationalist armies wrecked and mal-deployed — their best remaining forces deep in the southwest and Burma — while the Communist base areas, untouched by the campaign, stood closest to the Japanese-held north and Manchuria. The starting positions of the civil war’s race (Chapter 10) were set by a Japanese operation neither Chinese party controlled.

America’s China policy splits. The embassy’s field officers, reporting from Yan’an (the 1944 Dixie Mission) and from Ichigo’s wreckage, concluded the Communists would win a civil war; policy in Washington kept betting on Chiang while hedging with mediation. The incoherence — support one side, broker with both — runs straight into the Marshall Mission’s failure.

Collaboration’s bill comes due. Wang Jingwei’s regime, the puppet governments and their armies (hundreds of thousands strong) face the reckoning of 1945: their territories and arms become the prize both Chinese parties race for, and “who truly resisted” becomes the legitimacy currency of the postwar. The occupied east, misgoverned twice over, greets its “liberation” by carpetbagging officials — and remembers.

THE FULL ANSWER, ARGUED

Count what can be counted. The Nationalists fought virtually every conventional battle of the war — Shanghai, Wuhan, three Changshas, Ichigo — and took the overwhelming share of military casualties; twenty-two major engagements to the Communists’ one large offensive (the Hundred Regiments, 1940), after which Yan’an deliberately husbanded its forces. The Communists fought the other war — sabotage, ambush, village defense across an occupied north the Nationalists could not reach — and absorbed brutal reprisal campaigns; their claim to have been the resistance is inflated, but “they hid for eight years” is propaganda in the other direction. The honest formulation: the Nationalists fought Japan’s army, and were broken by the effort; the Communists fought Japan’s occupation, and were built by it. The answer matters because both regimes founded their legitimacy on this war — Taipei’s and Beijing’s textbooks still disagree — and because van de Ven, Mitter and Yang Kuisong have spent decades correcting both official memories. When a question stays politically alive for eighty years, historiography is part of the history.

AN INTERESTING FACT

When the coastal universities fled inland in 1937–38, three of the greatest — Peking, Tsinghua and Nankai — merged into the National Southwestern Associated University (Lianda) in Kunming, teaching eight years in tin-roofed sheds under air raids, with professors hauling their libraries by the basket. Its faculty and students included a startling share of modern China’s intellectual founders — among them Yang Chen-ning and Tsung-Dao Lee, who would share the 1957 Nobel Prize in Physics, taught in classrooms that paused for bombing runs. The state was decaying; the civilization it was defending was not.
