The Stilwell Road (Sino-India Road/Ledo Road)

More Picture

The Sino-India Road, also known as the Ledo Road or Stilwell Road, was a military supply route constructed during World War II as part of the efforts by China and the United States to maintain vital connections between China and its Allied forces. Stretching from Ledo in India through Myanmar to Kunming in China, this road played an instrumental role in supporting China’s resistance against Japanese forces and became a symbol of Sino-American cooperation.

The road was initially named after General Joseph Stilwell, a key U.S. officer who oversaw its construction. Today, the Stilwell Road continues to be a historical landmark, reflecting the enduring bonds forged during a critical period of World War II. A dedicated exhibit at the Anti-Japanese War Memorial Museum (抗战纪念馆) in Tengchong (腾冲) provides visitors with a closer look at the history of this strategic route.

The Ledo Road (Burmese: လီဒိုလမ်းမ), originally built during World War II, was a crucial overland connection between British India and China. It was constructed to deliver supplies to China after the Japanese cut off the Burma Road in 1942. The road was later renamed Stilwell Road in honor of General Joseph Stilwell (史迪威), an American Army officer, at the suggestion of Chiang Kai-shek (蒋介石) in early 1945. The road traversed several regions, including Shingbwiyang (兴布依央), Myitkyina (密支那), and Bhamo (勐卯) in Kachin State (克钦邦) of Myanmar (缅甸), and eventually connected to Kunming (昆明), China.

History of the Stilwell Road

The Need for the Road

The Ledo Road was initiated after the Japanese cut off the Burma Road in 1942, leaving the Western Allies with no overland route to supply China in its fight against Japan. With the airlift over the Himalayas, known as the Hump, proving insufficient, an alternative route had to be found. The Ledo Road was selected as the new supply line.

On December 1, 1942, General Sir Archibald Wavell (英国远东战区总司令) and General Joseph Stilwell (史迪威) decided to make the construction of the road a joint American and Chinese operation. The road was designed to connect Ledo (列多) in Assam, India, to the Mong-Yu (孟余) road junction in Burma, where it would connect to the Burma Road, which led to Kunming in China.

The Human and Technical Challenges

The construction was an enormous challenge, with 15,000 American soldiers (including African-American troops) and 35,000 local laborers working under extreme conditions. The road was built through difficult terrain, including the Patkai Range (帕德凯山脉) and the Pangsau Pass (旁萨乌山口), known as “Hell Pass” (地狱口) for its extreme difficulty. The first section of the road, which stretched 166 kilometers (103 miles) from Ledo to Shingbwiyang, was completed under difficult conditions. This section passed through steep gradients, narrow trails, and thick rainforests. The first bulldozer reached Shingbwiyang (兴布依央) on December 27, 1943, three days ahead of schedule.

The road was designed to handle an impressive 65,000 tons of supplies per month, which was expected to surpass the airlift capacity over the Himalayas (喜马拉雅山) at that time. However, General Claire Lee Chennault (克莱尔·李·陈纳德), commander of the U.S. Army Air Force’s Fourteenth Air Force, doubted the feasibility of the Ledo Road, believing that aircraft could deliver more supplies.

Key Challenges and Expanding the Road

The road construction was plagued by extreme weather conditions and the need to survey unknown terrain, particularly as most of Burma (缅甸) was under Japanese control. The road’s path had to be surveyed and adjusted during construction. The road had to span major rivers and secondary streams, requiring the building of numerous bridges. By January 12, 1945, the road connected to the Burma Road at the Mong-Yu Junction (孟余路口), a key milestone in its construction.

Key Locations Along the Stilwell Road

Chongqing (重庆) – The Starting Point for Supplies

During the war, Chongqing served as China’s wartime capital, making it the final destination for many of the supplies sent via the Stilwell Road. The first U.S. convoy arrived in Chongqing in 1945, cementing the road’s importance in China’s war effort. The city became a strategic hub for the transportation of goods and military supplies during the conflict.

Qinglong, Guizhou (晴隆，贵州) – A Historic and Dangerous Section: Twenty-four Bends (二十四道拐)

One of the most iconic parts of the Stilwell Road is the Twenty-four Bends, located just south of Qinglong County. This section of the road is famous for its sharp 60-degree inclines and 24 hairpin bends that climb up a steep slope, covering a distance of 4 kilometers. Built by U.S. Army engineers in 1942, the Twenty-four Bends became a symbol of both the engineering challenges and the strategic importance of this road.

During the war, this route was crucial in ensuring the constant movement of military supplies, despite the physical and environmental challenges it posed.

Kunming (昆明) – The Gateway to the Chinese Resistance

As the starting point for the Dian-Mian Road (滇缅公路), Kunming was a major hub along the Stilwell Road. The city’s location made it a strategic crossroads, connecting the road to China’s southwestern provinces and facilitating the transport of supplies from the Sino-India Road.

Chuxiong (楚雄) and Dali-Baoshan (大理—保山) – Vital Transport Nodes

These cities, located along the Stilwell Road, played key roles during the war as transit points for military materials. Chuxiong, a vital traffic hub in Western Yunnan, was crucial for moving supplies toward the Dali-Baoshan region, where the road passed through some of the most rugged terrain in the Hengduan Mountains.

Dehong (德宏) – The Southern Terminus at Mangshi and Ruili (芒市与瑞丽)

The southern end of the Stilwell Road in Dehong, which borders Myanmar, was vital for connecting the road to the Southeast Asian region. In Mangshi and Ruili, remnants like the Wanding Bridge (畹町桥) remain as historical markers of the road’s strategic significance.

Strategic Military Importance

Military and Logistical Impact

The Ledo Road served as a vital supply route for the Allies during the war. It allowed the Chinese (中国) to receive supplies in the fight against Japan, especially after the Myitkyina (密支那) airstrip was captured. As Allied troops advanced through northern Burma, the road was extended, and a network of fuel pipelines was also laid alongside it.

In total, the road stretched from Ledo to Kunming, covering a distance of 1,736 kilometers (1,079 miles). General Pick (皮克将军) led the first convoy of 113 vehicles from Ledo to Kunming, which reached its destination on February 4, 1945. Over the next six months, the road helped deliver 129,000 tons of supplies to China, complementing air supply routes that were vital to the war effort.

Strategic Limitations and Airlift Comparison

Despite the road’s importance, the tonnage of supplies transported via the Ledo Road never came close to the airlift capacities over the Hump. By July 1945, only 6,000 tons were transported over the Ledo Road compared to 71,000 tons flown over the Himalayas. Nevertheless, the Ledo Road helped relieve pressure on air transport and complemented existing supply lines.

Post-War Decline and Legacy

Decline After WWII

After the war, the road fell into disrepair as the demand for it diminished. In the late 1950s, expeditions such as the Oxford-Cambridge Overland Expedition (1955) and Eric Edis’ Expedition (1958) traveled parts of the road, documenting the deteriorating condition of the infrastructure. In the 1990s, the Indian government imposed strict travel restrictions due to ongoing insurgency activities in the region.

In 2010, the BBC reported that much of the road had been overtaken by jungle, and parts of the road were deemed impassable. However, portions of the road, particularly the section from Myitkyina to the China Border, were still accessible for vehicles.

Current Status of the Road

As of 2022, the Stilwell Road connects Dibrugarh (迪布尔嘎尔) in Assam, India with Kunming (昆明) in Yunnan Province, China, passing through Myanmar (缅甸). Several sections have been paved or reconstructed, including the stretch from Ledo to Nampong (南蓬) in India, and the Myitkyina to Tanai (塔耐) section in Myanmar, which was reconstructed by Yuzana Company (优赞公司) in 2011.

The road remains significant as part of Asian Highway 2 (AH2) in India, where it is recognized as NH315. Despite the challenges posed by political and security concerns in the region, efforts to revitalize the road continue, particularly with the focus on rebuilding sections of the road between Myitkyina and China.

Recent Tourism and Cultural Heritage

Recent years have seen limited tourism along the road, especially in India where Stilwell Park (史迪威公园) near Lekhapani (列卡潘尼) marks the road’s origin. In Myanmar, remnants of the war, such as gas tanks and World War II-era infrastructure, are visible along the route. In China, there are also historical sites related to the Songshan (松山) battles and Tengchong (腾冲) memorials.

Photographer Findlay Kember traveled the entire length of the road, documenting its present condition. His work highlighted the ongoing human legacy of the road and its historical importance, with particular emphasis on the Pangsau Pass (旁萨乌山口) and its role in the supply chain.

The Construction and Challenges

A Herculean Effort

Building the Stilwell Road was a monumental task, made even more difficult by the challenging terrain and wartime conditions. The route passed through difficult mountainous landscapes, dense jungles, and unpredictable weather conditions, which posed significant obstacles to both engineers and laborers.

The road construction began in 1942 and was completed in 1945, taking a total of 2 years and 3 months to finish. The effort was largely undertaken by U.S. military engineers working alongside Chinese soldiers and laborers. The road’s construction required overcoming steep inclines, heavy rains, and constant threats from Japanese forces.

Military and Civilian Collaboration

To overcome the difficulties of construction, General Stilwell organized a large-scale collaboration between U.S. Army engineers and Chinese soldiers. Civilians, particularly from Yunnan and Myanmar, also played a key role in building and maintaining the road. Despite a lack of proper machinery and resources, these workers used simple tools like picks, shovels, and explosives to carve out the road through some of the most rugged terrain.

The Road’s Legacy and Impact

The Lifeline of the War: A Critical Supply Route

Once completed, the Stilwell Road became the primary land route for delivering military supplies from the Allied forces in India to China. Over 50,000 tons of supplies were transported along this road, including ammunition, food, medical supplies, and military vehicles, which played a vital role in supporting China’s war effort.

This road helped to break Japan’s blockade, allowing China to receive critical supplies for its War of Resistance against Japanese Aggression (抗日战争). The Stilwell Road became a military transport icon, and its construction was heralded as a “miracle of wartime logistics.”

Symbol of Sino-U.S. Cooperation

The construction of the Stilwell Road is a testament to the close cooperation between the U.S. and China during World War II. The road’s construction and use symbolize the shared struggle against fascism and the significant sacrifices made by both nations. Several monuments and memorials along the route commemorate the contributions made by the Chinese, U.S., British, and Indian forces.

Modern-Day Preservation and Exploration

Today, parts of the Stilwell Road remain preserved, particularly in Qinglong (晴隆) and sections through Gaoligong Mountain (高黎贡山) in Yunnan. These historic routes attract visitors and history enthusiasts who wish to explore the legacy of the road and learn about the enormous efforts that went into its construction.

• Twenty-four Bends: This iconic stretch is still accessible but is preserved as a historic site, with limited vehicle traffic to protect its historical value.
