Deng Xiaoping's Advance into the Dabie Mountains: One Strategic Move That Turned the Tide of the Liberation War

The Thousand-Li Leap into Dabie Mountain: How Deng Xiaoping Helped Turn the Tide of Liberation War

August 7, 1947, on the banks of the Yellow River in southwestern Shandong. A massive army of nearly 130,000 soldiers was organizing crossing operations—this was the main force of the Jinjiluyu Field Army led by Liu Bocheng and Deng Xiaoping. The task made every staff officer catch their breath: a thousand-li leap into Dabie Mountain, penetrating deep into the heart of Nationalist-ruled territory, hundreds of kilometers from the rear bases. No liberated areas, no rear bases, no supply lines—the troops would have to survive and fight in enemy territory by themselves. This was a rare strategic maneuver in world military history. The order was signed by Mao Zedong, and the executors were Liu Bocheng and Deng Xiaoping. Two months later, 124,000 troops would surge southward from the southern bank of the Yellow River, pierce through the Nationalist blockade by a million-strong army, and eventually take root in Dabie Mountain. Why could this move reverse the entire trajectory of the Liberation War? What key role did Deng Xiaoping, serving as the political commissar of this operation, play in it?

The War Situation in 1947: Apparent Offense, Actual Danger

In the summer of 1947, the Liberation War entered its second year. Judging by the numbers alone, the People's Liberation Army seemed to be winning more and more decisively. In just one year, they had annihilated over 1.2 million Nationalist troops, while the PLA grew from 1.27 million to 1.9 million.

But Mao Zedong and the Central Military Commission knew clearly: the situation appeared good on the surface, but actually contained enormous hidden dangers.

Danger One: The war was being fought in liberated areas. All major campaigns were conducted in liberated areas—Shandong, the Shaan-Gan-Ning Border Region, and Shanxi-Chahar-Hebei. The liberated areas had a population of 1.4 billion, and the PLA numbered 1.9 million, meaning every seventy-four civilians had to support one soldier. Each campaign consumed vast amounts of grain, ammunition, and civilian labor. The liberated areas' rear base had been stretched to its limit.

Danger Two: Nationalist political space remained untouched. The Nationalist-ruled areas (with 1.5 billion people, including the prosperous southeastern coastal regions) had not experienced any warfare. This region was the political, economic, and military-industrial center of the Nationalist government. As long as this territory remained intact, Chiang Kai-shek possessed unlimited war potential.

Danger Three: American aid was continuous. American assistance to Chiang Kai-shek had not been interrupted. Weapons, funds, and advisors flowed in ceaselessly. If the war continued in the liberated areas, the Nationalist advantage of foreign support would become increasingly pronounced.

Mao Zedong had been constantly thinking about one question: how could the war be shifted from the liberated areas into Nationalist-ruled territory? This was not merely a military problem, but a strategic one.

Mao Zedong's "Coordination of Three Armies, Pincer Movement from Two Flanks"

On June 30, 1947, Mao Zedong made a strategic decision that shocked the Party: coordination of three armies and pincer movement from two flanks, with the main force leaping into Dabie Mountain.

The specific deployment was:

• Central route main force: Liu Bocheng and Deng Xiaoping's Jinjiluyu Field Army main force (130,000 troops) would storm across the Yellow River and leap into Dabie Mountain.
• Left flank (eastern route): Chen Yi and Su Yu's East China Field Army would advance from southwestern Shandong through Henan, Anhui, and Jiangsu, coordinating with the central route.
• Right flank (western route): Chen Geng and Xie Fuzhi leading part of the Jinjiluyu Field Army would cross the Yellow River southward and advance into western Henan.

The three armies would form a "pin" character formation, inserting themselves into the Central Plains and striking directly at the heart of Nationalist-ruled territory. Dabie Mountain, located at the junction of Hubei, Henan, and Anhui provinces, sat right next to the major cities of Wuhan and Nanjing, making it a critical area of Nationalist control. If Communist forces could take root here, it would be like driving a dagger into Chiang Kai-shek's ribs.

This strategy was extraordinarily bold and equally dangerous. For Liu Deng's army to leap into Dabie Mountain, they would have to:

• Abandon liberated bases: leave the Jinjiluyu liberated area and enter enemy-occupied territory.
• Abandon rear bases: have no logistical supply lines whatsoever; everything would be self-sufficient.
• Abandon heavy weapons: sacrifice large amounts of heavy artillery and equipment for mobility.
• Accept massive casualties: anticipate losing more than half the force.

After repeated discussion between Mao Zedong and Zhou Enlai, they selected Liu Bocheng and Deng Xiaoping to execute this task. Why them? Because Liu Bocheng was the master tactician among Communist military leaders, and Deng Xiaoping was an exceptionally capable political commissar. The two had worked together for over a decade and were the Communist military's most complementary "golden partnership."

The Liu-Deng Partnership: Fourteen Years of Forged Unity

The partnership between Deng Xiaoping and Liu Bocheng began in 1938. Shortly after the War of Resistance against Japan erupted, Deng Xiaoping was assigned as the political commissar of the 129th Division of the Eighth Route Army, with Liu Bocheng as the division commander. From that point until 1952, the two worked together for exactly fourteen years.

Their personalities complemented each other perfectly: Liu Bocheng was gentle and steady, with profound military knowledge and meticulous tactical planning; Deng Xiaoping was resolute and decisive, with strong political work abilities and rapid decision-making. Liu Bocheng called Deng Xiaoping "Comrade Xiaoping," while Deng Xiaoping called Liu Bocheng "Commander." When they coordinated, military decisions were dominated by Liu Bocheng, while political decisions were overseen by Deng Xiaoping.

Their brilliant military record spanned fourteen years and included countless classic campaigns: the Xiangtang Shop ambush during the War of Resistance (destroying 400 enemies), the Guanjiayu battle (under Peng Dehuai's command with Liu-Deng's 129th Division participating), the Shanxi campaign (1945, annihilating 40,000 enemies), the Handan campaign (1945, eliminating 30,000), the southwestern Shandong campaign (August 1947), the thousand-li leap into Dabie Mountain (1947), the Huaihai campaign (1948, with the Central Plains Field Army cooperating with the East China Field Army), the Yangzi crossing (1949), and the advance into southwestern China (1949-1950).

The coordination between this partnership was rare in Chinese Communist military history. In his later years, Deng Xiaoping recalled: "Commander Liu Bocheng was the most trusted comrade-in-arms of my entire life." Liu Bocheng similarly said in his twilight years: "The quality of a political commissar's work determines a unit's combat effectiveness. It was my good fortune to have Deng Xiaoping serve as my political commissar."

The Yellow River Crossing: The Urgent Mobilization of 120,000 Troops

In late July 1947, Deng Xiaoping and Liu Bocheng traveled to various units of the Jinjiluyu Field Army to convey Mao Zedong's strategic decision. This was a difficult political task, requiring 124,000 troops to accept a nearly suicidal mission: "abandon rear bases and leap into enemy territory."

Deng Xiaoping addressed a conference of regimental and higher-ranking cadres:

"Comrades, the Central Committee's decision is very clear: we are going to Dabie Mountain. This is an extremely difficult task—one might even say a nine-in-ten chance of death. But why must we do this?

Because we now face two paths: one path is to continue fighting in the liberated areas. We might ultimately win, but the people in the liberated areas cannot endure it. Tens of millions of people cannot survive. The other path is to bring the war to the enemy's own territory, to let the Nationalists also experience the flames of war.

The Central Committee has chosen the second path. This requires us to pay an enormous price. But history will not forget that in the critical moment of our entire revolutionary war, it was the main force of the Jinjiluyu Field Army that, risking life and death, opened the door to strategic counteroffensive. Comrades, can we do it?"

The room roared with the response: "We can!"

Deng Xiaoping's speech played a crucial role, transforming a nearly suicidal task into a glorious historical mission, making the entire army of cadres accept the necessity of this assignment. This was precisely the highest value of his role as political commissar: transforming the Central Committee's strategic intentions into the conscious action of the troops through understanding and communication of strategic decisions.

The Thousand-Li Leap: One Month of Arduous March

On August 7, 1947, Liu-Deng's army began crossing the Yellow River southward. The first units crossed at the Southwestern Shandong crossing point. Chiang Kai-shek judged that Liu-Deng was merely conducting an ordinary campaign operation and did not realize they intended to advance south several hundred kilometers.

On August 11, Liu-Deng's army broke through the Lunghai Railway and entered the Yellow River flood-ravaged area. This zone was created in 1938 when Chiang Kai-shek blew open the Huayuankou dike of the Yellow River—it covered hundreds of square kilometers of mire, swamps, and ruins. For troops to traverse this region meant sinking deep into mud with every step. Heavy artillery, supply vehicles, and trucks could not possibly pass through.

Liu Bocheng and Deng Xiaoping made a heart-wrenching decision for the entire army: abandon all heavy weapons. Field guns, artillery pieces, howitzers, trucks, and wagons were all buried or destroyed, keeping only rifles, machine guns, mortars, and other light weapons. It was extremely rare in world military history for a field army to engage in such "self-mutilation" by discarding heavy equipment.

In mid-to-late August, Liu-Deng's army emerged from the flood-ravaged zone and continued southward. On August 26, they forcefully crossed the Ru River, breaking through Nationalist blocking positions. On August 28, they crossed the Huai River and entered the outer perimeter of Dabie Mountain.

Chiang Kai-shek only then realized that Liu-Deng's army was truly advancing into Dabie Mountain! He hastily assembled over 300,000 troops to encircle and eliminate them. But it was too late—Liu-Deng's main force had already entered the Dabie Mountain region.

In early September, Liu-Deng's army dispersed throughout Dabie Mountain's various counties and districts, beginning to establish liberated bases. From the Yellow River to Dabie Mountain, in one month they covered more than 400 kilometers—124,000 troops completed this rare "strategic maneuver" in world military history.

The Difficult Years in Dabie Mountain

The Liu-Deng army entering Dabie Mountain faced challenges far more arduous than the river crossing and advance:

First, harsh environmental conditions: Dabie Mountain had steep terrain, winding paths, and unpredictable climate. Soldiers from the north struggled to adapt to the hot and humid southern mountain climate, with dysentery, malaria, and athlete's foot spreading on a massive scale.

Second, scarce food and clothing: the troops had no rear supply base and had to "requisition locally." But Dabie Mountain was an impoverished region with low grain yields. The troops had to find every possible way to gather grain.

Third, weak mass foundation: Dabie Mountain had once been an old liberated base of the Red Fourth Front Army, but after more than a decade of Nationalist rule, the people were forced to distance themselves from the Communist Party. When the troops arrived, they needed to re-mobilize the masses—a process filled with difficulties.

Fourth, Nationalist encirclement and suppression: Chiang Kai-shek assembled thirty-three brigades and over 300,000 troops to focus on exterminating Liu-Deng's army. The Liu-Deng forces had to fight while constantly moving, always ready to break through.

By late 1947, Liu-Deng's army had been reduced from 124,000 when entering Dabie Mountain to just over 70,000—nearly half were lost. But they persisted stubbornly and managed to secure a foothold in Dabie Mountain.

"One Move to Reverse the Situation": The Strategic Value of the Dabie Mountain Leap

Although Liu-Deng's army paid an enormous price, its strategic value far exceeded the troop losses.

First, it brought the war to the Nationalist doorstep. Dabie Mountain was adjacent to Wuhan and Nanjing, and the presence of Liu-Deng's army meant Nationalist-ruled areas experienced warfare for the first time. From this point forward, the main theater of war shifted from liberated areas to Nationalist-ruled territory.

Second, it pinned down 300,000 Nationalist elite troops. To encircle and eliminate Liu-Deng's forces, Chiang Kai-shek had to withdraw units from other battlefields (originally intended for assaults on liberated areas) to Dabie Mountain. This greatly relieved pressure on other fronts for the PLA.

Third, it opened the Central Plains battlefield. With Liu-Deng in Dabie Mountain, Chen-Su in Henan-Anhui-Jiangsu, and Chen-Xie in western Henan, the three armies formed a strategic "pin" character formation. The entire Central Plains became the new battlefield for large-scale PLA operations.

Fourth, it shifted overall strategic initiative. From the moment Liu-Deng leaped into Dabie Mountain, the PLA possessed national strategic initiative. The Nationalist forces shifted from strategic offense to strategic defense, though they themselves did not yet realize it.

Mao Zedong later evaluated: "The Liu-Deng army's thousand-li leap into Dabie Mountain was the beginning of strategic counteroffensive in the Liberation War. This one move reversed the entire situation."

Deng Xiaoping's Political Wisdom

The political abilities Deng Xiaoping demonstrated during this operation were textbook-worthy in Party history:

First, ideological work was thorough: from before the operation through its execution to its conclusion, he made troop morale his highest priority. Facing dangerous tasks, harsh conditions, and massive casualties, he used every means to inspire morale and strengthen conviction.

Second, discipline was strict: after entering Dabie Mountain, Deng Xiaoping placed special emphasis on troop discipline. He drafted the famous "Discipline Code for the Dabie Mountain Advance," prohibiting harm to civilians, forced recruitment, seizure of supplies, or harassment of the people. These rules helped the Dabie Mountain population gradually recognize the difference between Communist troops and Nationalist forces.

Third, he possessed strategic vision: Deng Xiaoping profoundly understood the strategic significance of "leaping into Dabie Mountain," and repeatedly explained to troops the necessity of this action. He said: "The suffering we endure now is in exchange for victory in China's entire revolution. We must keep this account clear."

Fourth, he coordinated operations: as political commissar, Deng Xiaoping not only managed ideological-political matters but jointly made military decisions with Liu Bocheng. His political judgment and Liu Bocheng's military judgment complemented each other, forming the unique command artistry of the Liu-Deng partnership.

The Echo of History

Dabie Mountain today is an important red tourism area in China. In Honggan County of Hubei Province, Xin County of Henan Province, and Jinzhai County of Anhui Province, one can see commemorative monuments, historic sites, and revolutionary stories of Liu-Deng's army everywhere. The most central location is the "Memorial Museum of the Liu-Deng Army's Thousand-Li Leap into Dabie Mountain" in Qiliping Town of Honggan, Hubei.

Walking into the memorial, the most striking feature is a "Casualty Wall" densely inscribed with the names of over 70,000 fallen martyrs who died in Dabie Mountain between 1947 and 1948. Many were northern soldiers who could not adapt to the southern climate and died from disease; many fell in battle; many did not even have their names recorded.

What did their sacrifice achieve? It achieved the shift in strategic initiative for the entire Liberation War. From September 1948 to January 1949, three major campaigns—the Liaoyang-Shenyang, Huaihai, and Beiping-Tianjin campaigns—unfolded in succession, with 8 million Nationalist elite troops annihilated within a year. Without the Liu-Deng army's leap into
