In May 1942 the Japanese moved Coates to Burma. At the Kilo-30 and Kilo-55 camps on the Burma-Thailand Railway he cared for hundreds of prisoners of war under deplorable conditions. Coates subsequently described his medical practice at Kilo-55 to the International Military Tribunal for the Far East: in a bamboo lean-to, with his only instruments a knife, two pairs of artery forceps and a saw (used by the camp butchers and carpenters), his daily work consisted of 'segregating the sick from the very sick . . . curetting seventy or eighty ulcers during the morning . . . and, in the afternoon, proceeding to amputate nine or ten legs'. In December 1943 the Japanese sent Coates to Thailand. There, from March 1944, he was chief medical officer of a prisoner-of-war hospital (10,000 beds) at Nakhon Pathom (
Nakhon Pathom). Through 'his initiative, resource and enthusiasm he was responsible for many improvisations which provided artificial limbs, transfusions and surgical appliances'. (Sir)
Edward Dunlop recalled that Coates's 'short, upright figure with a ghost of a swagger, a Burma cheroot clamped in his mouth, and his staccato flow of kindly, earthly wisdom became the object of hero-worship and inspiration'. With the cessation of hostilities, Coates returned to Melbourne in October 1945, transferred to the Reserve of Officers on 6 December and was appointed O.B.E. in 1946. Coates was a key witness at the
Tokyo War Crimes Tribunal in '46, was appointed an OBE in '47, was an RSL delegate at the signing of the Peace Treaty in the US in '51, and was knighted by the Queen in '55. . While Dunlop was the senior officer at Nakhon Pathom, he deferred to Coates’ extensive medical knowledge. Coates had served during World War I and was also well-known and respected among prisoners of war. ==Career==
