Background Information:

Every combat Theater of WW2 had its unique medical history, but nowhere did disease pose a greater threat to the American G.I. and to military operations than in the bitter war against Japan!
US Armed Forces faced the dual challenges of fighting and supporting its troops in primitive, largely tropical environments, burdened by severe logistical problems. Previous conflicts, such as the Spanish-American War, and World War 1 had complicated the situation, as it conferred upon the United States many Pacific islands and overseas territories (Philippines, Guam), while the Japanese acquired former German possessions.

As War erupted in Europe, President Franklin D. Roosevelt proclaimed a state of National Emergency in September 1939, and in August 1940, Congress summoned the National Guard into Federal service and called-up the Reserves! As the United States Army reorganized and professionalized, the Army Medical Department began to plan and then to mobilize for war too, spending many months feverishly making preparations that had been delayed too long…

General view of the 18th General Hospital, in New Zealand in 1942. It was only briefly stationed there, taking over hospital care from the Navy, before being transferred to Fiji. In Oct 42, work began for the construction of a brand-new 1000-bed General Hospital (39th Gen Hosp) which would remain the only permanent US Army Hospital in New Zealand (Feb 43 - Oct 44).

For many years, the principal Army unit had been the Hawaiian Division, and this force then represented the largest contingent stationed outside the continental United States. The first medical build-up was essentially based on expanding medical facilities and depots, constructing new hospitals, and revising medical contingency plans. The next project called for a more elaborate defense of the Commonwealth of the Philippines, under a new command; the United States Army Forces in the Far East (USAFFE) under Lt. General Douglas MacArthur.
The war against Japan was fought in an immense area that covered roughly 1/3 of the earth’s surface! Although most of the decisive battles took place on the islands in the Pacific, inevitably bringing American Forces closer the Japanese mainland; fighting also occurred on mainland Asia. Distances were enormous, and everything could only be moved by sea or air – climates varied as well as landforms and included cold wind-swept Aleutians, jungle-clad Melanesian islands, palm-fringed Micronesia atolls, damp and tropical heat, volcanic islands, complex landmasses, steep mountain ranges, wooded high plateaus, rain forests, dense jungles – environmental  conditions brought its own characteristic medical consequences involving frostbite, trenchfoot, malaria, fever, and jungle rot … All those elements had to be taken into account by the Medical Department, although none of the diseases were normally fatal, they could nevertheless put soldiers out of action as effectively as combat casualties.

Partial view of medics taking care of casualties at the 11th Portable Surgical Hospital, somewhere in the jungles of New Guinea, picture taken July 44. Normally only a 25-bed facility, the 11th expanded to 50, even admitting 102 patients during 17-27 Jun 44, performing 87 operations with only 1 death! Surgeons and staff worked continuously for 72 hours. The Portable Surgical Hospitals provided skilled surgical care in rugged jungle environment and could be set up and moved within a relative short time; patients and medical facilities were usually kept under canvas or temporary huts.

The Beginning:

After the attack against Pearl Harbor, and the fall of the Philippines, Australia would emerge as the ‘great’ Allied base in 1942, playing a role in the Pacific War like that of Great Britain in western Europe. Of course, we should not forget, that in December 1941, Britain and America had agreed to concentrate their combined forces against Germany FIRST!
In order to simplify wartime operations, the Anglo-American Combined Chiefs of Staff on 24 March 1942,  assigned the United States ‘responsibility’ for the conduct of the war in the Pacific! The region was divided into 2 separate Commands – on 18 April 1942, Lt. General Douglas MacArthur became Supreme Commander, Southwest Pacific Area (SWPA) covering the Philippines, Australia, the Netherlands East Indies, and New Guinea – on 8 May 1942, Admiral Chester W. Nimitz was named Commander Pacific Ocean Areas (CINCPAC) including the vast region stretching from the Bering Straits to Antartica, including the Hawaiian Islands and Japan itself. The Command was further subdivided into 3 main sectors; the North Pacific Area (e.g. Aleutians), the Central Pacific Area (e.g. Hawaiian, Mariana, Marshall, Palau, Caroline, and Marshall Islands) and the South Pacific Area (e.g. Solomon and Gilbert Islands). Primary instructions were to contain Japan’s southward advance, to hold Australia, to keep key islands of the South Pacific as bases for future operations, and to protect and defend lines of communications with the United States…

World War 2:

Until the very last months of the fighting, the US Medical Department faced immense obstacles – supply lines were tenuous and environmental conditions almost intolerable, malaria epidemics broke out, logistical difficulties beset medical planners, diseases took their toll, medical support often broke down, amphibious medical evacuation had to be revised, and yet altogether death rates from disease were only slightly over 1 / 1000 troops / per year!
New methods of preventive medicine were created, logistics were improved, and recent discoveries were now provided on a large scale, such as Penicillin – Atabrine – and DDT. The ultimate lesson may however lie in the flexibility of spirit and organization shown by medical personnel, who were able to save lives and improve general health conditions during those years of bitter and unrelenting struggle for peace – in those harsh times the Medical Department successfully maintained the ‘fighting strength of the Army’.

Port Dispensary Tent on Biak Island, New Guinea, Aug 44. The large US Base (Base "H") opened on Biak in Aug 44 under CoL. August W. Splitter, MC. The 28th Hosp Cen operating on the island included 3 Gen Hosp and 1 Sta Hosp. From end Nov 44, evacuation took place by air, and C-54 aircraft carried patients directly to the ZI, via Guadalcanal, Canton Is., and Honolulu.

View of the Main Ward of a prefabricated Station Hospital, somewhere in Australia, picture taken in 43. Prefabricated Hospitals were ordered from Australian manufacturers (since US-manufactured units could not be supplied until late 43) and consisted of plywood, masonite, fibrolite, and corrugated iron. These units consisted wholly of portable huts, to which were added concrete floors, roofing and wallsheeting of corrugated iron or asbestos cement; the units came with the necessary tools and assembly instructions. Medical units were advised to include in their organization one well-qualified plumber, one electrician, and two carpenters. The units were constructed and disassembled by medical personnel, assisted by engineers, and could be transported by aircraft.

Medical Clearing Companies

In view of the ‘special’ environment and kind of warfare, Clearing Companies often functioned as small Field Hospitals in the Pacific. The other reason was that most battles were small and Hospital units might be absent from the Task Force or remote from the fighting line.

394th MED CLR CO – Jan 45 Luzon (operated a temporary 100-bed medical facility)
893d MED CLR CO – Jan 45 Luzon (operated a temporary 100-bed medical facility) Mar 45 Manila (operated a provisional small hospital)

View of Seagrave Hospital (formally activated as the 896th Med Clr Co in Oct 44) treating casualties in the open, near Myitkyina, Burma. The Hospital in fact operated like a mobile Evacuation Hospital, and whenever feasable, severe medical cases were either evacuated by rail or by air. During the campaign to capture Myitkyina, the Seagrave Hospital, supported by personnel of the 42d and 58th Ptbl Surg Hosp and a surgical team from the 25th Fld Hosp, treated American, British, Chinese, Indian, and Kachin wounded (and later also Japanese PWs). Dr. Gordon S. Seagrave was an American medical missionary running a Hospital close to the Burma Road and the Chinese border, his wide experience and organization were very much appreciated by both British and US authorities, and he was therefore sworn into the US Army as a Major in the Medical Corps on 21 Apr 42.

Separate Medical Collecting Companies

Collecting Companies had a hard time fighting in the Asia-Pacific region. They often had to evacuate casualties from temporary forward Aid Stations, and run a Collecting Station, in a harsh and hostile environment.

409th MED COLL CO – Mar 45 Manila (operated an Air Evac Strip at Rosales and Quezon City)
506th MED COLL CO – Dec 44 New Guinea
644th MED COLL CO – Jan 45 Luzon (operated a temporary 50-bed civilian hospital)

Buna casualty arrives at the 171st Station Hospital, at Port Moresby, Papua, Dec 42. This 500-bed Hospital arrived at Port Moresby early December and operated together with the 153d Sta Hosp, the 10th Evac Hosp, and a provisional Battalion of the 135th Med Regt. Because of malaria, those patients who, after treatment, were expected to remain unfit for duty more than 14 days, were usually sent to mainland Australia (Townsville or Brisbane).

Portable Surgical Hospitals (Units)

Portable Surgical Hospitals were first developed in Australia and later adapted to provide skilled surgical care in jungle fighting during the Papuan campaign. These ‘special’ medical units were later attached to Task Forces for providing early frontline surgical care in amphibious operations. The Portable Surgical Hospitals consisted of 4 Officers and 33 EM who carried the necessary equipment and supplies on their backs – depending on circumstances, these units were attached to a Regiment, a Division, or even to an Army. This kind of Hospital  was unique to the Theater.
