forces, but unlike previously, they took that attitude that the Japanese who were behind them were just as cut off as the British. The situation maps of the fighting along the roads leading to Imphal resembled a slice of marble cake, as both sides used the jungle to outflank each other. Another major change by the British was that use of air support both as an offensive weapon to replace artillery and as a logistical tool to transport men and equipment. For example, the 5th Indian Infantry Division was airlifted straight from the now-quieter Arakan front up to the central front and were in action within days of arriving. By the end of the campaigning season, both Kohima and Imphal had been relieved, and the Japanese were in full retreat. The lessons learnt in Burma on how to fight in the jungle and how to use air transport to move troops around would lay the foundations of how to conduct large-scale jungle campaigns in future wars. Unconventional jungle warfare Immediately after the fall of Malaya and Singapore in 1942, a few British officers, such as Freddie Spencer Chapman, eluded capture and escaped into the central Malaysian jungle, where they helped to organize and train bands of lightly-armed local ethnic Chinese communists into a capable guerrilla force against the Japanese occupiers. What began as desperate initiatives by several determined British officers probably inspired the subsequent formation of the above-mentioned early jungle-warfare forces. The British and the Australians contributed to the development of jungle warfare as the unconventional, low-intensity, guerrilla-style type of warfare understood today. V Force and Force 136 were composed of small bodies of soldiers and irregulars, equipped with no more than small arms and explosives but were rigorously trained in guerrilla warfare-style tactics, particularly in close-quarter combat, and fought behind enemy lines. They were joined in Burma by American led Kachin guerrillas were armed and coordinated by the American liaison organisation, OSS Detachment 101, which led, armed, and co-ordinated them. Another small force operating in the Far East was the Australian led Z Special Unit, which carried out a total of 81 covert operations in the South West Pacific theatre, some of which involved jungle warfare. Cold War British experience during Malayan Emergency After the war, early skills in jungle warfare were further honed in the Malayan Emergency, when in 1948 guerrilla fighters of the Malayan Communist Party (MCP)
