Chapter 797: Solomon Islands Cleaning – Makira/ San Christobal and Russel Islands
In the Solomon Islands the Japanese Empire, more exactly the Imperial Japanese Navy tried to use the last American carrier losses for more offensives, but their last own losses in transports by land-based Allied fighters and bombers had shown that they needed to secure the Allied airfields on the other islands as well. On the Russel Islands, the Japanese had landed forces to oppose the Allied base under construction by Seabees after the American evacuation of Guadalcanal. From there the Allies hoped to oppose and threaten the Japanese and Co-Prosperity Sphere posiitons on Guadalcanal and New Georgia, hoping to drive them off those islands and back towards Japan again. On January 21, 1943, Seabees landed in the Russell Islands to construct an air and naval base to lend support for these planned Allied operation. The Russell Islands, which lie northwest of Guadalcanal, consist of two principal islands, Banika and Pavuvu, and a number of islets. The topography of Banika Island, where most of the naval development took place, was highly favorable for the projected facilities. Well-drained shore areas, deep water, protected harbors, and lack of malaria made it a good location for a base to support landing craft, PT boats, and small craft. The greatly sloping terrain and well-drained coral subsoil facilitated construction. The major portion of the 33rd Battalion departed from Guadalcanal for the Russell Islands on January 20, 1943, on LCT's and LST's, with whatever equipment could be put aboard during their hasty evaluation, later to be improved by further Allied supplies from larger ships. Immediately upon arrival, they started work on the fighter strip. Progress was slow, due to inadequate equipment and lack of personnel, but by April 13, the emergency landing of a P-38 was possible. On March 20, 1943, the 35th Battalion, which had followed the 33rd, in early March, was given the task of completing a strip 3100 feet long by 150 feet wide, in twenty days. A detachment of 200 men from the 34th Battalion with much of that battalion's heavy equipment was also brought to Banika to help rush the work. The strip was surfaced with coral, which was available in abundance. It was during this construction that the Allies were first encountering the Japanese in the east of the island who had tried to construct their own airfield and build a coastal battery against Allied ships heading for Guadalcanal from the west. By early August, the main runway, one warm-up area, 60 feet by 450 feet, and 14 revetments for Airstrip No. 1 had been completed despite constant Japanese assaults. The Japanese originally had planned for a shore bombardment even with bigger battleships guns and carrier support, as their fleets had learned to give island forces and landings supported after the lessons learned during Midway, the Solomone Islands and Guadalcanal operations. However the Japanese Commander, Otani Haruko hoped that they could capture the Allied build airfield like in Guadalcanal and Malaita to use them for their own purpose and save time as they would not have to construct them themselves, as the Americans had much better equipment for doing so.
During August, despite smaller Japanese probing attacks, the 35th Battalion completed the construction of a second 4500-foot strip, with a taxiway and dispersal areas for 40 planes. Work was then started on the lengthening of the first strip to 6,000 feet to make it suitable for medium bombers, and on a bomber taxiway. The hardstands had to be constructed to allow them to accommodate heavier aircraft, and more had to be provided. The two fields were to be used by the Army Air Force planes in their attacks on enemy positions in Guadalcanal and New Georgia. In conjunction with the construction of the airstrips, the Seabees also erected quonset huts and dallas huts for use as quarters, galley, mess halls, offices, operations building, and dispensaries at each field. By April 1943, the 33rd Battalion had erected an aviation-gasoline tank farm of eight 1,000-barrel tanks, together with piping and fittings, for Airstrip 1. A second tank farm of six 1,000-barrel tanks, completed in June for Airstrip 2, was connected to the landing dock by a 1,200-foot pipeline. Japanese ground attacks and enemy bombing by ship and air on May 25, 1943 caused considerable damage to Tank Farm 1. One tank was set on fire and was completely destroyed; three others were punctured by shrapnel. The piping was also damaged. Repairs were completed in five days. Gasoline service to the airfield was afterwards again maintained without interruption. In June, five more tanks were planned to be added at Tank Farm 1 and four at Tank Farm 2. Development of waterfront facilities at Banika was not begun by the 35th Battalion immediately upon its arrival in May 1943, as by then the Japanese attacks had to freshly landed forces from nearby Guadalcanal and New Georgia increased, driving the Americans from the airfield and their base established around it into a more defensive coastal position that was under threat by Japanese naval bombardment. With the evacuation of Guadalcanal, the Russel Island base was under constant bombardment by Imperial Japanese Navy ships and land based bombers and fighters from New Georgia and Guadalcanal, leaving the Allies little choice but to evacuate the small forward airfield and base as well by June 1943.
On Makira/ San Christobal meanwhile the Japanese, Chosen and Taikoku forces faced much more heavy resistance from the 34,000 Allied forces on the island. However the Allies had to supply these numbers and that was not possible from the island alone, so Japanese naval bombers and submarines had a field day hunting Allied transports and escorts from their nearby island bases as the Allies without a strong air and naval support of their own lacked the means of protecting them. Sure the USS Essex (CV-9) had been speed up and launched on 13 June 1942, accelerating it's construction, so that it was finished on 13 November 1942 under Captain Donald B. Duncan, but with it and the Wasp as the only American carriers in the Pacific facing superior Japanese carrier and land base numbers in the Solomon Islands, the Americans did not dare to risk them at the moment until new carriers were finished and they had reserves to stop a continued Japanese push towards Hawaii, the West Coast and Australia while at the same time also continuing their own planned island hopping. The American forces were superior in numbers and had better defensive positions, but the Japanese had a plan. Weapons from Unit 483 already tested in China to a small extent as well as more massively in Siberia, anthrax, bubonic plague, cholera, smallpox, botulism, paratyphoid fever and other deadly diseases were used with the help of so called bacilli bombs, bacilli shells and bacilli grenades filled with the infection and shot or thrown at the enemy. Soon the diseases had spread all over Makira and the majority of the already often only sparsely trained Allied forces, or the wounded veterans. Because similar reports had come from New Guinea and Guadalcanal, the Allies at first believed they had brought these infections with them. Infected wounds often lead to amputations, meaning further numbers of Allied forces on Makira were unable to fight and unlike New Guinea where the diseases would remain in the jungle on animals and plans, infecting Japanese settlers for decades to come to the island after the war because of the sparse native population, here on Makira the smaller island and larger population by Allied soldiers meant the infections spread fast and all over the place, even to the freshly landed Japanese reinforcements.
Like on Guadalcanal more died by infections then the real fighting, with soon 6,400 Allies dead by infection and plague rather then direct fighting. Nimitz and MacArthur knew that evacuation could mean spread this diseases to Australia, New Zealand or Hawaii as well and therefore hesitated for another evacuation, especially as it would have meant giving the Japanese nearly full control of the Solomon Islands as well. However no further reinforcements and supplies were send to Makira as well in fear of further infections and dead of the already heavy causalities among the Marines and American forces in the Solomon Islands who desperately needed new freshly trained forces to arrive. Japanese air and naval bombardment, as well as the shorter Japanese fresh reinforced troops from Guadalcanal, New Georgia and even Rabaul and New Guinea meant that the Japanese in the end managed to take Makira under heavy losses themselves with 9,200 of Japanese dead, half of them from disease not fighting, including many of the SNLF (Special Naval Landing Forces) that now meant that all of the operations in Papua/ New Guinea/ New Guinea were given over to the Imperial Japanese Army with coastal and naval landing navy support as the Imperial Japanese Navy needed all reserves and even some army support it could get for their planned operation to cut off Australia from Allied supply lines from America after the recent losses.
