The Battle of Yenangyaung (Chinese: 仁安羌大捷; pinyin: Rén ān qiāng Dà jié; lit. 'Great Victory at Yenangyaung') was fought in Burma, now Myanmar, from 16–19 April 1942. Part of the Burma Campaign of World War II, the battle was fought between Chinese and British allied forces on one side, and Japanese forces on the other. The battle took place in the vicinity of Yenangyaung and its oil fields.

Background

The Japanese 55th Division invaded Burma on 22 December 1941. After the Japanese captured Rangoon in March 1942, the Allies regrouped in Central Burma. The newly formed Burma Corps, consisting of British, Indian and locally raised Burmese troops, and commanded by Lieutenant General William Slim, attempted to defend the Irrawaddy River valley. Meanwhile, the Chinese Expeditionary Force (in Burma) defended the Sittaung River valley to the east. After the Japanese captured Singapore and the Dutch East Indies, they were able to use divisions released by these successes, and captured trucks, to reinforce their army in Burma and launch attacks into Central Burma.

One of the Japanese objectives in the Irrawaddy River valley was the Yenangyaung oil fields. The battle for the oil fields started on 10 April^[1] and continued for a week. The Japanese attacked the 1st Burma Division on the Allied right and 48th Indian Infantry Brigade at Kokkogwa at night during a storm, but were repulsed with heavy casualties.^[1] On the next day, the 2nd Royal Tank Regiment (2nd RTR) was engaged near Magwe at Thadodan and Alebo. From 13 to 17 April, the British fell back under attacks by the Japanese. On several occasions Japanese roadblocks split the Burma Frontier Force (an internal security force acting as infantry), 1st Burma Division, the British 7th Armoured Brigade HQ and 2nd RTR into three forces.

On 15 April, Lieutenant General Slim gave orders for the oil fields and refinery to be demolished.^[2] The situation became so critical that General Harold Alexander, commanding the Burma Army, asked Lieutenant General Joseph Stilwell, the American commander of the China Burma India Theater and Chief of Staff to Chiang Kai-shek, to move the Chinese 38th Division into the Yenaungyaung area immediately.

Battle

On 16 April, almost 7,000 British soldiers, and 500 prisoners and civilians were encircled by an equal number of Japanese soldiers from the IJA 33rd Division at Yenangyaung and its oil field.

The 33rd Division was able to advance between Slim's 17 Division at Taungdwingyi and the 1st Burma division south of Yenangyaung. Fearing that his BurCorps may become trapped, Slim called upon Sun Li-jen's Chinese 38th Division for help.^[3]

Fires at Yenanguang emanating from destroyed equipment and facilities

General Sun requested to lead his entire division to the rescue of 1st Burma Division, but General Lo Cho-ying, commander of the Chinese Expeditionary Force in Burma, refused. On 17 April, General Sun instead led his 113th Regiment with only 1,121 men, of which only 800 were combat personnel, in the mission. Because the Chinese had no artillery or tanks, Lieutenant General Slim assigned the 7th Armoured Brigade, commanded by Brigadier John Anstice, to General Sun. The brigade consisted of two regiments (battalions) of M3 Stuart light tanks and a battery of 25-pounder guns.^[4]

For the next three days, the Chinese attacked southwards. The temperatures reached as high as 114 °F (46 °C) and a pall of smoke from the demolished oil wells and refineries hung over the battlefield.^[5]

Meanwhile, 1st Burma Division fought its way to and across the Pin Chaung river, where they met with the relief column on 19 April. On the next day, the Chinese force attacked south toward Yenaungyaung and Pin Chaung. The attack caused the Japanese to suffer heavy casualties, but the Allied forces were too weak to hold the oil fields and had to retreat to the north.^[6]

Results

For the British, according to Allen, "Deprived of a supply port at Rangoon, then of its source of fuel at Yenangyaung, the question was no longer whether to retreat, but where to?"^[3]^: 70
