Battle of Imphal

The Battle of Imphal (Meitei: Japan Laan[1][2], lit.'Japanese invasion') took place in the region around the city of Imphal, the capital of the state of Manipur in Northeast India from March until July 1944. Japanese armies attempted to destroy the Allied forces at Imphal and invade India, but were driven back into Burma with heavy losses. Together with the simultaneous Battle of Kohima on the road by which the encircled Allied forces at Imphal were relieved, the battle was the turning point of the Burma campaign, part of the South-East Asian theatre of World War II. The Japanese defeat at Kohima and Imphal was the largest up until that time,[4] with many of the Japanese deaths resulting from starvation, disease and exhaustion suffered during their retreat.[3] According to voting in a contest run by the British National Army Museum, the Battle of Imphal was bestowed as Britain's Greatest Battle in 2013.[5][6]

The under Lieutenant-General Motoso Yanagida would surround and destroy the 17th Indian Division at Tiddim, then attack Imphal from the south.

33rd Infantry Division

Yamamoto Force, formed from units detached from the Japanese 33rd and 15th Divisions under Major-General (commander of 33rd Division's Infantry Group),[nb 1] would destroy the 20th Indian Division at Tamu, then attack Imphal from the east. The force was supported by the 14th Tank Regiment, equipped with 66 assorted tanks, under Lieutenant Colonel Nobuo Ueda[8] and the 3rd Heavy Artillery Regiment under Lieutenant Colonel Kazuo Mitsui.[8]

Tsunoru Yamamoto

The under Lieutenant-General Masafumi Yamauchi would envelop Imphal from the north. This division was still arriving from road-building duties in Thailand and was understrength at the start of the operation.

15th Infantry Division

In a separate subsidiary operation, the under Lieutenant-General Kotoku Sato would isolate Imphal by capturing Kohima on the Imphal-Dimapur road, and then advance to Dimapur.

31st Infantry Division

Allied counter-attacks[edit]

North[edit]

By 1 May, all Japanese attacks had come to a halt. Slim and Scoones began a counter-offensive against the Japanese 15th Division. This division was the weakest of the Japanese formations, and if it was defeated, the siege would be broken (once Kohima was recaptured). The progress of the counter-attack was slow. The monsoon had broken, making movement very difficult. Also, IV Corps was suffering some shortages. Although rations and reinforcements were delivered to Imphal by air, artillery ammunition had to be conserved.

Casualties[edit]

The Japanese defeat at Kohima and Imphal was the largest up until that time.[32] They had suffered 54,879 casualties, including 13,376 dead (plus 920 casualties in the preliminary battles in Assam).[3] Most of these losses were the result of starvation, disease and exhaustion.


The Allies suffered 12,603 casualties.[3]

Aftermath[edit]

The Japanese had also lost almost every one of the 12,000 pack horses and mules in their transport units and the 30,000 cattle used either as beasts of burden or as rations,[12] and many trucks and other vehicles. The loss of pack animals was to cripple several of their divisions during the following year. Mutaguchi had sacked all of his divisions' commanders during the battle. Both he and Kawabe were themselves subsequently relieved of command.


In December, Slim and three of his corps commanders (Scoones, Christison and Stopford) were knighted by the viceroy Lord Wavell, at a ceremony at Imphal in front of Scottish, Gurkha and Punjab regiments. Slim was created KCB, the others were made KBEs.

War cemetery[edit]

After the war, the Commonwealth War Graves Commission set up Imphal War Cemetery and Kohima War Cemetery to commemorate the British and the Indian soldiers who died during the Second World War.[36]
