What are the Three Decisive Campaigns?

Liaoshen Campaign (12 September to 2 November 1948). Lin Biao's Northeast Field Army (around 700,000) faced Wei Lihuang's KMT forces (around 550,000) in Manchuria. The PLA cut KMT garrisons off from each other. Jinzhou fell on 14 October. Changchun surrendered after a six-month siege; perhaps 150,000 civilians died of starvation inside the city.

What is liaoshen Campaign?

Lin Biao's Northeast Field Army (around 700,000) faced Wei Lihuang's KMT forces (around 550,000) in Manchuria. The PLA cut KMT garrisons off from each other. Jinzhou fell on 14 October.

What is huaihai Campaign?

The largest single campaign of the war. The Eastern China Field Army (Chen Yi) and the Central Plains Field Army (Liu Bocheng, Deng Xiaoping) totalled around 600,000. KMT forces under Du Yuming and Liu Zhi numbered around 800,000, including five elite armies.

What is pingjin Campaign?

Lin Biao's Fourth Field Army (around 1 million) plus North China forces surrounded the Beiping-Tianjin region (Fu Zuoyi, around 520,000 KMT). Tianjin fell on 15 January after a brief assault. Fu Zuoyi negotiated the peaceful surrender of Beiping on 31 January 1949.

Chiang spread KMT forces too thinly garrisoning cities; the PLA concentrated overwhelming force at chosen points. The German and US-trained divisions, designed for conventional war, were destroyed faster than they could be replaced.

Hyperinflation destroyed urban living standards and the KMT tax base. The Gold Yuan reform failed.

KMT corruption was endemic; the "Four Big Families" (Chiang, Soong, Kung, Chen) accumulated wealth while soldiers went unpaid. Press censorship and Blue Shirt repression alienated intellectuals and students.

What is land question?

The KMT never tackled rural inequality. CCP land reform mobilised peasant volunteers and supplied PLA logistics on a scale the KMT could not match.

What is international?

US aid declined sharply after 1947 (the China White Paper of August 1949 effectively conceded defeat). Soviet aid to the CCP, including arms and technical support, continued.

What is strategic competence?

Mao's strategic directives showed sustained discipline. Lin Biao's Manchurian campaign, Chen Yi's Huaihai operations, and Peng Dehuai's Shaanxi defence were all expertly executed.

Land reform, base-area governance, and the Mass Line gave the CCP a depth of peasant support the KMT lacked.

PLA conduct in captured cities, particularly Beiping and Shanghai, was reported by Western journalists as comparatively disciplined. The contrast with retreating KMT looting helped consolidate urban support.

What is organisation?

The CCP had emerged from Yan'an as an ideologically united, hierarchically disciplined organisation. The KMT was a coalition of cliques.

NESA Practice (NESA)-style practice: Why did the Chinese Communists win the civil war by 1949?

A 15-mark "why" answer needs developed factors and a named historian. **Thesis.** The CCP won because three factors converged: superior strategy (mobile warfare based on rural mass support), KMT structural collapse (inflation, corruption, demoralisation), and the decisive 1948-1949 campaigns that destroyed the Nationalist field armies before they could regroup. **Strategic phases.** Phase 1 (mid-1946 to mid-1947): KMT offensive. 4.3 million KMT troops attacked 1.2 million CCP regulars; the KMT captured Yan'an (March 1947) but bled their best units. Phase 2 (mid-1947 to mid-1948): Liu Bocheng and Deng Xiaoping crossed the Yellow River (June 1947) into the Dabie Mountains; initiative passed to the CCP. **The three decisive campaigns (Sept 1948-Jan 1949).** Liaoshen (12 Sept-2 Nov 1948): Lin Biao destroyed 470,000 KMT troops in Manchuria.

NESA Practice (NESA)-style practice: Explain the significance of the Huaihai Campaign (November 1948 to January 1949).

A 5-mark "explain" answer needs three developed points. **Scale.** The largest single campaign of the civil war. Around 600,000 PLA (Eastern China and Central Plains Field Armies under Chen Yi and Liu Bocheng) faced around 800,000 KMT under Du Yuming, in the area between the Huai River and Xuzhou. Combined commitments approached 1.4 million. **Outcome.** PLA destroyed five KMT armies including most of Chiang's remaining German and US-trained divisions. KMT losses were around 555,000 killed, wounded, or captured. PLA losses around 134,000. The campaign ended with Du Yuming's encircled force surrendering on 10 January 1949. **Strategic effect.** The road to Nanjing was open. With Manchuria gone (Liaoshen, October 1948) and the north secured (Pingjin, January 1949), Huaihai destroyed the last KMT field army of significance. The Yangtze crossing in April 1949 followed almost without resistance. Chiang's mainland defeat was settled at Huaihai.

What this dot point is asking

NESA expects you to explain the course of the civil war from the renewal of fighting in 1946 to the PLA's victory in 1949. Strong answers integrate strategic phases, the three decisive campaigns, the KMT's structural collapse, and the CCP's political and military advantages.

In plain English

In 1946 the Nationalists (KMT) looked unbeatable. They had about four times as many soldiers as the Communists, American guns, and every big city and railway in China. Imagine a heavyweight boxer who outweighs his opponent three to one but has a glass jaw and is broke: that was the KMT. To hold all those cities they had to leave troops guarding each one, so their huge army was spread thin everywhere and strong nowhere.

Meanwhile the Communist army (the PLA) did the opposite. It kept moving, ganged up its whole force on one isolated KMT garrison at a time, smashed it, and moved on - like a smaller team that never splits up and always fights you five-on-one. Out in the villages the Communists gave land to poor peasants, who then volunteered as soldiers and carried the army's supplies on millions of wheelbarrows. At the same time the KMT's money was turning to confetti: prices doubled and redoubled until a banknote was worth almost nothing, savings vanished, and unpaid soldiers stopped fighting. In just four months over the winter of 1948 to 1949, three giant battles wiped out the KMT's best armies. By the end of 1949 the Communists had won the mainland and Chiang Kai-shek's government fled to Taiwan.

The must-know spine

Full civil war resumed in July 1946. The KMT began with around 4.3 million troops, US equipment and every major city; the CCP had around 1.2 million regulars and base areas of around 100 million people. The KMT took Yan'an (19 March 1947) but lost the initiative when Liu Bocheng and Deng Xiaoping crossed the Yellow River (June 1947). The three decisive campaigns - Liaoshen (12 Sept to 2 Nov 1948), Huaihai (6 Nov 1948 to 10 Jan 1949) and Pingjin (29 Nov 1948 to 31 Jan 1949) - destroyed around 1.5 million KMT troops. The PLA crossed the Yangtze on 20 to 21 April 1949 (Nanjing fell 23 April); the mainland was conquered by the end of 1949. KMT collapse was driven by hyperinflation (the failed Gold Yuan reform, August 1948), corruption and land-question failure; CCP victory by strategy, land reform and discipline.

The answer

The strategic balance at mid-1946

The KMT entered the war with apparent overwhelming advantage:

Around 4.3 million troops, including 39 US-equipped divisions.
US Lend-Lease equipment, including aircraft and naval vessels.
Control of all major cities, all railways, and all industrial centres.
International recognition as the legitimate Chinese government.

The CCP held:

Around 1.2 million regulars and 2.6 million militia.
Base areas covering around 100 million people.
Japanese arms acquired in Manchuria.
Soviet covert support, especially in Manchuria.

But raw numbers concealed the KMT's weaknesses: brittle morale, fragile finances, divided high command, and the structural problem that gains in territory cost garrisons.

Phase 1: KMT offensive (mid-1946 to mid-1947)

Chiang launched general offensives across north China. The KMT captured Zhangjiakou (Kalgan, October 1946), then Yan'an itself on 19 March 1947. Mao evacuated the capital but treated the loss strategically: "If the enemy advances, we retreat."

KMT forces took territory but bled men. PLA general Peng Dehuai, defending Shaanxi-Gansu-Ningxia, conducted a mobile defence that exhausted Hu Zongnan's columns. Manchuria saw heavy fighting; Lin Biao retreated and rebuilt.

By mid-1947 the strategic initiative had shifted. Liu Bocheng and Deng Xiaoping led an audacious counter-thrust across the Yellow River into the Dabie Mountains (June-August 1947), operating in the KMT rear in central China. The PLA was no longer simply defending.

Phase 2: PLA counter-offensive (mid-1947 to mid-1948)

The PLA renamed itself the People's Liberation Army (1946 progressively, formally 1947) and shifted to conventional combined-arms warfare. PLA strength reached around 2.8 million by early 1948; KMT strength fell to around 3.6 million.

CCP land reform under the May Fourth Directive (May 1946) and the Outline Land Law (October 1947) brought millions of peasant volunteers into the army. PLA logistics in north China relied on around 5 million civilian porters and labour brigades.

The KMT economy began to collapse. Inflation accelerated: the Fabi exchanged at 25 to the US dollar in 1937, around 7,700 by August 1946, around 12 million by mid-1948. The Gold Yuan reform (19 August 1948) replaced the Fabi at 3 million Fabi to 1 Gold Yuan; within three months the Gold Yuan had lost 90 per cent of its value. Public confidence collapsed.

The Three Decisive Campaigns

Liaoshen Campaign (12 September to 2 November 1948): Lin Biao's Northeast Field Army (around 700,000) faced Wei Lihuang's KMT forces (around 550,000) in Manchuria. The PLA cut KMT garrisons off from each other. Jinzhou fell on 14 October. Changchun surrendered after a six-month siege; perhaps 150,000 civilians died of starvation inside the city. Mukden fell on 1 November 1948. Around 470,000 KMT troops were killed or captured. Manchuria was lost.
Huaihai Campaign (6 November 1948 to 10 January 1949): The largest single campaign of the war. The Eastern China Field Army (Chen Yi) and the Central Plains Field Army (Liu Bocheng, Deng Xiaoping) totalled around 600,000. KMT forces under Du Yuming and Liu Zhi numbered around 800,000, including five elite armies. Civilian labour brigades brought PLA supplies; KMT logistics seized up. The campaign destroyed five KMT armies. Around 555,000 KMT troops were killed, wounded, captured, or defected. The road to Nanjing was open.
Pingjin Campaign (29 November 1948 to 31 January 1949): Lin Biao's Fourth Field Army (around 1 million) plus North China forces surrounded the Beiping-Tianjin region (Fu Zuoyi, around 520,000 KMT). Tianjin fell on 15 January after a brief assault. Fu Zuoyi negotiated the peaceful surrender of Beiping on 31 January 1949. Around 520,000 KMT troops were captured or defected.

In four months, the PLA destroyed around 1.5 million KMT troops, including most of the elite American and German-trained divisions. The mainland war was effectively over.

Crossing the Yangtze and the southern campaigns

Chiang resigned the presidency on 21 January 1949; Li Zongren became acting president. Peace talks at Beiping (April 1949) failed. The PLA crossed the Yangtze on 20-21 April 1949. Nanjing fell 23 April. Hangzhou 3 May. Shanghai 27 May. Wuhan 16 May.

Chen Geng's Second Field Army took the south-west; Lin Biao's Fourth Field Army moved south; Peng Dehuai's First Field Army took the north-west (Xinjiang, September 1949). Major cities fell in sequence: Guangzhou 14 October 1949, Chongqing 30 November 1949, Chengdu 27 December 1949.

By the end of 1949 the PLA controlled all of mainland China except parts of Tibet and the offshore islands. Tibet was occupied in October 1950 (Chamdo); Hainan Island in May 1950.

Reasons for KMT defeat

Strategic: Chiang spread KMT forces too thinly garrisoning cities; the PLA concentrated overwhelming force at chosen points. The German and US-trained divisions, designed for conventional war, were destroyed faster than they could be replaced.
Economic: Hyperinflation destroyed urban living standards and the KMT tax base. The Gold Yuan reform failed.
Political: KMT corruption was endemic; the "Four Big Families" (Chiang, Soong, Kung, Chen) accumulated wealth while soldiers went unpaid. Press censorship and Blue Shirt repression alienated intellectuals and students.
Land question: The KMT never tackled rural inequality. CCP land reform mobilised peasant volunteers and supplied PLA logistics on a scale the KMT could not match.
International: US aid declined sharply after 1947 (the China White Paper of August 1949 effectively conceded defeat). Soviet aid to the CCP, including arms and technical support, continued.

Reasons for CCP victory

Strategic competence: Mao's strategic directives showed sustained discipline. Lin Biao's Manchurian campaign, Chen Yi's Huaihai operations, and Peng Dehuai's Shaanxi defence were all expertly executed.
Mass base: Land reform, base-area governance, and the Mass Line gave the CCP a depth of peasant support the KMT lacked.
Discipline: PLA conduct in captured cities, particularly Beiping and Shanghai, was reported by Western journalists as comparatively disciplined. The contrast with retreating KMT looting helped consolidate urban support.
Organisation: The CCP had emerged from Yan'an as an ideologically united, hierarchically disciplined organisation. The KMT was a coalition of cliques.

Historiography

Odd Arne Westad (Decisive Encounters: The Chinese Civil War 1946-1950, 2003) is the standard.

Suzanne Pepper (Civil War in China: The Political Struggle 1945-1949, 1978) is on the political dimension.

Lloyd Eastman (Seeds of Destruction: Nationalist China in War and Revolution 1937-1949, 1984) emphasises KMT structural failure.

Steven Levine (Anvil of Victory, 1987) on Manchuria.

Lionel Chassin (The Communist Conquest of China, 1965) is older but still useful operational history.

Diana Lary (China's Civil War, 2015) on the social experience.

How to read a source on this topic

Sources include PLA campaign maps, KMT communiques, US State Department reporting (the Davies-Service group), Mao's strategic directives, and contemporary news coverage. Three reading habits.

First, separate the campaigns from the political backdrop. Liaoshen, Huaihai, and Pingjin together decided the war militarily; the political collapse was already advanced.

Second, treat KMT corruption claims with care but not scepticism. The Soong-Kung connection to government finances and the "Four Big Families" rhetoric was CCP propaganda, but the underlying inflation and graft were real.

Third, watch the international angle. The Truman administration's August 1949 White Paper effectively conceded defeat; "loss of China" politics in the US shaped the Truman-MacArthur quarrel in 1950-1951.

Model exam responses

A. Source response (5 marks). Source: a paraphrased, owned extract from a US State Department report of 1948 noting that KMT divisions in Manchuria were "well equipped but poorly led," that their commanders quarrelled, and that morale was breaking as pay arrived worthless. Assess the usefulness of this source for a historian studying the KMT defeat.

The source originates with a US State Department observer in 1948, an informed but external official perspective whose purpose was to assess, not to celebrate or condemn - which makes it comparatively candid evidence of KMT weakness. It is highly useful for the internal causes of defeat: it corroborates the divided high command (Wei Lihuang's isolated Manchurian garrisons), the gap between US equipment and Nationalist leadership, and the collapse of morale as hyperinflation made pay meaningless (the Gold Yuan reform of August 1948 lost around 90 per cent of its value within three months). Its limitation is scope: a snapshot of Manchuria in 1948 cannot capture the PLA's side - Lin Biao's combined-arms competence in the Liaoshen Campaign, or land reform mobilising peasant logistics. Read critically, the source is strong on why the KMT lost from within and weak on why the CCP won; a full answer pairs it with the operational record.

Marker's note: a top response states origin, perspective and purpose, separates what the source is useful FOR (KMT internal collapse) from what it omits (CCP strengths), anchors this in specific dated own knowledge, and ends in a judgement rather than paraphrasing the extract.

B. Essay paragraph (from a 25-mark response on whether the Communist victory owed more to KMT failures or CCP strengths).

The KMT's economic collapse shows how far victory was handed to the CCP by Nationalist failure rather than seized by force alone. The Fabi fell from 25 to the US dollar in 1937 to around 12 million by mid-1948, and the Gold Yuan reform of 19 August 1948 lost roughly 90 per cent of its value within three months, wiping out the savings of the very urban middle class on which the KMT depended and leaving conscripts unpaid in worthless notes. Corruption sharpened the wound: the "Four Big Families" rhetoric tracked real graft, and soldiers proved unwilling to die for a regime so visibly enriching its elite, defecting in mass at Pingjin where Fu Zuoyi surrendered Beiping. As Lloyd Eastman argues in Seeds of Destruction (1984), hyperinflation was the symbol and solvent of KMT collapse. Yet Odd Arne Westad (Decisive Encounters, 2003) is right that this internal rot still had to be converted into victory on the battlefield - which is why the decisive factor was the CCP's strategic capacity to exploit the opening the KMT had created.

Marker's note: the paragraph argues a single proposition (economic collapse as an enabling KMT failure), supports it with dated specifics and figures, and sets two historians in genuine tension - Eastman's internal-collapse thesis against Westad's strategic agency - rather than name-dropping. Sustained argument plus historiography is what lifts a paragraph into Band 6.

Command words and weaving historiography

Read the verb first. "Account for" and "Assess the reasons" want CAUSES weighed and ranked (rank KMT collapse against CCP competence), not a chronicle; "To what extent / Evaluate" want a JUDGEMENT defending a thesis; "Assess the usefulness/reliability" of a source wants ORIGIN, MOTIVE and PERSPECTIVE, then a verdict. For source questions run O-M-P-U: Origin, Motive, Perspective, then Usefulness/limitation - and with civil-war sources always ask whether you are reading KMT communiques, PLA propaganda, or external US reporting, each with its own slant. Weave historians as a clash, not a list: pit internal collapse (Eastman - inflation and graft hollowed out the Nationalist state) against strategic agency (Westad - the campaigns were decisive CCP achievements), with Pepper on the political struggle, then say which carries more weight. One historian used in genuine tension beats five name-dropped.

Examples in context

Example 1. The three decisive campaigns (September 1948 to January 1949). Liaoshen, Huaihai, and Pingjin campaigns destroyed around 1.5 million KMT troops. Odd Arne Westad (Decisive Encounters, 2003) draws on Chinese archives to argue Lin Biao's Manchurian successes were strategically decisive. Diana Lary (China's Civil War, 2015) uses provincial sources to show how hyperinflation, conscription, and corruption hollowed out KMT legitimacy.

Example 2. The fapi currency collapse (1948). By August 1948, one US dollar bought 11 million fapi yuan. The Gold Yuan reform of August 1948 failed by November. Lloyd Eastman (Seeds of Destruction, 1984) treats hyperinflation as the symbol of KMT collapse: middle-class savings vanished and conscript morale broke. Felix Boecking (No Great Wall, 2017) emphasises customs revenue collapse as the structural cause.

Show worked answer →

A 15-mark "why" answer needs developed factors and a named historian.

Thesis: The CCP won because three factors converged: superior strategy (mobile warfare based on rural mass support), KMT structural collapse (inflation, corruption, demoralisation), and the decisive 1948-1949 campaigns that destroyed the Nationalist field armies before they could regroup.
Strategic phases: Phase 1 (mid-1946 to mid-1947): KMT offensive. 4.3 million KMT troops attacked 1.2 million CCP regulars; the KMT captured Yan'an (March 1947) but bled their best units. Phase 2 (mid-1947 to mid-1948): Liu Bocheng and Deng Xiaoping crossed the Yellow River (June 1947) into the Dabie Mountains; initiative passed to the CCP.
The three decisive campaigns (Sept 1948-Jan 1949): Liaoshen (12 Sept-2 Nov 1948): Lin Biao destroyed 470,000 KMT troops in Manchuria. Huaihai (6 Nov 1948-10 Jan 1949): 600,000 PLA against 800,000 KMT; KMT losses around 555,000. Pingjin (29 Nov 1948-31 Jan 1949): 520,000 KMT captured or surrendered; Beiping surrendered peacefully under Fu Zuoyi.
Yangtze crossing (20-21 April 1949): Nanjing 23 April, Shanghai 27 May, Guangzhou 14 October, Chongqing 30 November.
KMT collapse: Hyperinflation (Fabi at 12 million per US dollar by 1948; Gold Yuan reform failed within three months); "Four Big Families" corruption; brutal conscription; mass defections; US disengagement (August 1949 White Paper).
CCP success: Strategic flexibility; land reform mobilising around 100 million peasants; PLA discipline; Soviet aid (Japanese arms in 1945).
Historiography: Westad (2003), Pepper (1978), Eastman (1984). Markers reward dated campaigns, casualty figures, the inflation, and at least one CCP and one KMT factor.

Practice (NESA)5 marksExplain the significance of the Huaihai Campaign (November 1948 to January 1949).

Show worked answer →

A 5-mark "explain" answer needs three developed points.

Scale: The largest single campaign of the civil war. Around 600,000 PLA (Eastern China and Central Plains Field Armies under Chen Yi and Liu Bocheng) faced around 800,000 KMT under Du Yuming, in the area between the Huai River and Xuzhou. Combined commitments approached 1.4 million.
Outcome: PLA destroyed five KMT armies including most of Chiang's remaining German and US-trained divisions. KMT losses were around 555,000 killed, wounded, or captured. PLA losses around 134,000. The campaign ended with Du Yuming's encircled force surrendering on 10 January 1949.
Strategic effect: The road to Nanjing was open. With Manchuria gone (Liaoshen, October 1948) and the north secured (Pingjin, January 1949), Huaihai destroyed the last KMT field army of significance. The Yangtze crossing in April 1949 followed almost without resistance. Chiang's mainland defeat was settled at Huaihai.

Markers reward the dates, the casualty figures, the link to the Yangtze crossing, and Chen Yi-Liu Bocheng command.

Practice questions

Original practice questions graded from foundation to exam level, each with a full worked solution. Try them before revealing the solution.

foundation3 marksOutline the strategic balance between the KMT and the CCP at mid-1946.

Show worked solution →

A 3-mark "outline" wants three distinct, correctly weighted points.

KMT apparent advantage: Around 4.3 million troops (including 39 US-equipped divisions), US Lend-Lease equipment, control of all major cities, railways and industry, and international recognition as the legitimate government.
CCP position: Around 1.2 million regulars plus 2.6 million militia, base areas covering around 100 million people, Japanese arms seized in Manchuria, and covert Soviet support.
The hidden weakness: KMT numbers concealed brittle morale, fragile finances, a divided high command, and the structural trap that holding territory tied down garrisons.
Marking criteria: 1 mark each for a correct KMT strength, a correct CCP strength, and the KMT's underlying vulnerability; do not simply narrate the later campaigns.

foundation4 marksExplain how the three decisive campaigns of 1948 to 1949 destroyed the KMT's military position.

Show worked solution →

A 4-mark "explain" needs a dated cause-and-effect chain.

Liaoshen (12 Sept to 2 Nov 1948): Lin Biao's Northeast Field Army cut KMT garrisons apart in Manchuria; Jinzhou fell on 14 October and Mukden on 1 November, costing the KMT around 470,000 troops and the loss of Manchuria.
Huaihai (6 Nov 1948 to 10 Jan 1949): Chen Yi and Liu Bocheng's field armies (around 600,000) destroyed five KMT armies (around 555,000 losses) between Xuzhou and the Huai River, opening the road to Nanjing.
Pingjin (29 Nov 1948 to 31 Jan 1949): Lin Biao surrounded the Beiping-Tianjin region; Tianjin fell on 15 January and Fu Zuoyi surrendered Beiping peacefully on 31 January, costing around 520,000 KMT.
The effect: In four months the PLA destroyed around 1.5 million KMT troops, including the elite US and German-trained divisions, settling the mainland war.
Marking criteria: 1 mark for each correctly dated campaign and outcome; 1 mark for linking the three to the destruction of the KMT field armies.

core5 marksSource A (paraphrased, owned): A standard account of the war argues that the KMT's apparent superiority in 1946 - millions of troops, American equipment and every major city - was hollow, because each city captured had to be garrisoned, every railway guarded, and every defeat paid for in a currency that was already losing its value by the week. Using Source A and your own knowledge, explain why the KMT's numerical advantage did not deliver victory. [5 marks]

Show worked solution →

A 5-mark "explain ... using the source" wants the source decoded, then linked to own knowledge.

Decode the source: Source A argues the KMT's 1946 advantage was self-defeating: territory had to be garrisoned, so manpower was dispersed defending fixed points while the currency collapsed beneath the war effort.
Own knowledge - dispersal: Chiang spread around 4.3 million troops thinly across cities, railways and industrial centres; the PLA could then concentrate overwhelming local force, as at Huaihai, where around 600,000 PLA destroyed around 555,000 KMT.
Own knowledge - finance: The Fabi fell from 25 to the US dollar (1937) to around 12 million (mid-1948); the Gold Yuan reform of August 1948 lost around 90 per cent of its value within three months, breaking conscript morale and the tax base.
Outcome: Numbers without concentration, sound finance or morale could not stop a mobile, peasant-supported PLA.
Marking criteria: 1 mark for reading the source's "garrison trap" point; 1-2 marks for own knowledge on overextension/concentration; 1 mark for the currency collapse; 1 mark for the link to defeat.

core5 marksSource B (paraphrased, owned): A historian of the Nationalist collapse contends that the regime was not so much beaten on the battlefield as destroyed from within - by an inflation that wiped out the savings of the very urban middle class on which the KMT depended, and by a corruption so visible that few were willing to die for it. Using Source B and your own knowledge, assess the usefulness of this interpretation for understanding the KMT defeat. [5 marks]

A 5-mark "assess the usefulness" question rewards origin/perspective plus own knowledge, ending in a judgement.

Perspective: Source B reflects the Lloyd Eastman position (Seeds of Destruction, 1984), which foregrounds structural and internal collapse over battlefield outcomes - useful because it explains why KMT armies dissolved and defected rather than fighting on.
Corroboration: It fits the record: the Gold Yuan reform of August 1948 failed within three months; the "Four Big Families" rhetoric tracked real graft; brutal conscription and unpaid soldiers produced mass defections, as at Pingjin where Fu Zuoyi surrendered Beiping.
Limitation: By stressing internal rot it can underweight the military story - Lin Biao's Manchurian victories and PLA combined-arms warfare actually destroyed the field armies. Westad (Decisive Encounters, 2003) insists the campaigns were strategically decisive, not merely symptomatic.
Judgement: Highly useful for explaining KMT brittleness, but it must be read alongside the operational history; the regime was hollowed out from within and then broken in the field.
Marking criteria: 1 mark for identifying the structuralist perspective; 1-2 marks for own knowledge corroborating internal collapse; 1 mark for a limitation (the military dimension); 1 mark for a judgement on usefulness.

A 6-mark "account for" wants ranked, dated causes, not a narrative.

Why Manchuria mattered first: It was China's industrial heartland and the entry point for Japanese arms seized in 1945, with Soviet covert support; whoever held it held the war's decisive theatre.
The rebuilding: After early reverses Lin Biao retreated and rebuilt the Northeast Field Army into the PLA's strongest force (around 700,000 by 1948), while Wei Lihuang's KMT garrisons (around 550,000) were left isolated in the cities.
The decisive blow: The Liaoshen Campaign (12 Sept to 2 Nov 1948) cut the garrisons apart - Jinzhou on 14 October, Mukden on 1 November - destroying around 470,000 KMT troops and the KMT's modern field army before the wider war was settled.
The consequence: Lin Biao's victorious force then drove south into the Pingjin Campaign, demonstrating that the Manchurian theatre was decisive: it destroyed the KMT's best troops first.
Marking criteria: 1-2 marks for why Manchuria was strategically central; 1-2 marks for Lin Biao's rebuilding and the Liaoshen outcome with dates/figures; 1 mark for the link to Pingjin/the wider war; 1 mark for a ranked judgement.

This is an extended-response/essay. Markers reward a sustained, evidence-based argument that addresses the comparison directly and weaves in historiography - not a narrative.

Band-6 PLAN

Thesis. KMT failures opened the door, but CCP strengths walked through it: hyperinflation, corruption and overextension hollowed out the Nationalist state, yet only the PLA's strategic competence and land-reform mass base could convert that weakness into total victory. The two are inseparable, but the decisive agent was the CCP's capacity to exploit the opening.
Argument 1 - KMT failures (the enabling factor). The KMT lost its own base: the Fabi collapsed (25 to the US dollar in 1937, around 12 million by mid-1948) and the Gold Yuan reform failed within three months; "Four Big Families" corruption and brutal conscription bred mass defections; Chiang dispersed 4.3 million troops garrisoning cities.
Argument 2 - CCP strengths (the decisive factor). The PLA shifted from guerrilla to combined-arms warfare, concentrating force at chosen points; land reform (May Fourth Directive 1946; Outline Land Law 1947) mobilised peasants and around 5 million civilian porters; CCP discipline in captured cities won urban acquiescence.
Argument 3 - The decisive military moment. The three campaigns (Sept 1948 to Jan 1949) destroyed around 1.5 million KMT troops; Lin Biao's Manchurian victory came first, Huaihai opened Nanjing, Pingjin secured the north. KMT collapse alone did not win the war - the PLA had to destroy the field armies.
Historiography. Lloyd Eastman (Seeds of Destruction, 1984) stresses KMT structural failure - inflation and graft; Odd Arne Westad (Decisive Encounters, 2003) insists the campaigns were strategically decisive CCP achievements; Suzanne Pepper (Civil War in China, 1978) emphasises the political struggle and the CCP's success in winning legitimacy.
Judgement. Weigh Eastman's internal-collapse thesis against Westad's strategic CCP agency: the KMT's failures were necessary but not sufficient; the decisive factor was the CCP's strategic and political capacity to exploit them.

MODEL PARAGRAPH (Argument 3)

The clearest proof that CCP strengths, not KMT failures alone, decided the war lies in the three decisive campaigns of September 1948 to January 1949. KMT inflation and corruption were already advanced, yet the Nationalists still fielded millions of men and held every major city; collapse from within did not, by itself, end the war. What ended it was the PLA's destruction of the Nationalist field armies. Lin Biao's Liaoshen Campaign cut apart around 550,000 KMT troops in Manchuria, taking Jinzhou on 14 October and Mukden on 1 November 1948 and costing the KMT around 470,000 men. At Huaihai, Chen Yi and Liu Bocheng concentrated around 600,000 PLA against around 800,000 KMT and destroyed five armies, opening the road to Nanjing; at Pingjin, Fu Zuoyi surrendered Beiping rather than be annihilated. In four months around 1.5 million KMT troops, including the elite US and German-trained divisions, were gone. As Odd Arne Westad argues, these were strategically decisive operations, not mere symptoms of decay; the CCP had to win them, and did.

Marker's note. A band-6 response sustains the comparison throughout (always weighing "KMT failures" against "CCP strengths" rather than listing both), anchors every claim in dated evidence and figures, sets at least two historians in genuine tension (Eastman's internal collapse vs Westad's strategic agency), and reaches a graded judgement. Narrating the campaigns without arguing which factor was decisive caps the response in the middle bands.
