Keen as Mustard (film)

In the later days of World War II evidence was found in Papua New Guinea of Japan's preparedness to use chemical weapons, in the form of bombs loaded with a mixture of mustard gas and lewisite. British and American military planners became acutely aware of their lack of knowledge about the effects of such materials on soldiers in tropical areas. An Australian Chemical Warfare Research & Experimental Section was formed in 1942 and a top-secret facility established in Queensland near Innisfail and later Proserpine, where a wide range of tests was performed by British, American and Australian researchers on volunteers from Australian defence personnel, with nurses and laboratory assistants recruited from the Australian Army Medical Women's Service. Initial tests proved that mustard gas was around four times as potent in tropical climates, with greatest aggravation to the skin occurring in the sweaty areas of the groin, buttocks, back of legs, neck and armpits.

A large 100 cubic metres (3,500 cu ft) controlled environment stainless-steel gas chamber was designed by biochemists J. W. Legge and (later Professor Sir) Hugh Ennor to house volunteer subjects to ascertain the effectiveness of various materials and designs of protective clothing, during periods of physical exertion and after being subject to normal wear and tear. Other tests were conducted to determine the limits of endurance of soldiers in performing arduous tasks after bodily exposure to mustard gas. Gas masks or respirators were used to minimise inhalation of the gas.

The determined resistance put up by Japanese soldiers against the Americans in their assault on Tarawa in November 1943 prompted the US Army, which had sustained terrible losses in taking the island, to make plans for use of chemical weapons in further attacks of the kind. General Douglas MacArthur was in favor of this approach, heavy naval bombardment having been unexpectedly ineffective at lowering the enemy's resistance. Brook Island, off the Queensland coast around 30 km east of Cardwell, was prepared with various forms of tunnel and foxhole to simulate the kind of emplacements used by the Japanese army, and goats tethered in these locations. Bombers then carpeted the island with mustard gas bombs and the following day unprotected Australian soldiers were landed on the island to assess the damage, and spent 12 hours there, suffering some lung damage and blisters where their bodies came into contact with contaminated foliage.

The Allies never used gas against the enemy, as Japan surrendered following the dropping of atom bombs on Hiroshima and Nagasaki. The Chemical Warfare Unit was top secret and its very existence was denied for many years. Many of the volunteers had never served overseas, and so did not receive the monitoring and preferential health treatment accorded other ex-servicemen by the Department of Veterans' Affairs. Mustard gas is known to damage DNA by alkylation, and it has been suggested that the experiments were responsible for adverse long-term health effects on some of these volunteers.

The film was in 1989 Highly Commended in the Walkley Awards for Australian Journalism.[1]

It was a finalist for the United Nations Association of Australia Media Peace Prize.

The Brook Island trials were much more extensive than this documentary film suggests, relying largely on the evidence of a few participants. There were at least three major trials on the island, listed here. This article also mentions unsubstantiated stories about the use of human guinea-pig volunteers from American prisons.

The Australian War Memorial, Canberra has a great deal of material, freely available, related to the Australian Chemical Warfare Research & Experimental Section, some of which is reproduced here.

Goodwin wrote an essay on her research and the making of the film for the series "Working with Knowledge" conference papers online, Session 6 entitled "Science Archives: Humanising and Popularising the Stories", available here
