SwPac, end of July 1943 -
By judicious use of recon intel, the Allies determine that the time is right for an agressive offensive in the SouthWest Pacific. Having secured and improved the airfields at Milne Bay, USAAF and RAAF bombers hit Japanese airfields throughout New Guinea, New Britian, and the Solomons.
July begins with Australian troops landing at Rossel Island. Despite an intense naval and arial bombardment, the defenders put up a tenacious defense. The warrior spirit of the defenders is however, insufficient to stave the tide of the battle, and island is secured in a week.
Next, MacArthur bypasses the IJA stronghold at Buna, and orders the invasion of Lae and it's supporting nearby bases. Planning for the invasion of Lae involved over 3x full divisions, plus supporting units. Lae and it's satalite bases are held by several regiments, that are well dug into the moutainous terrain. The Japanese coastal guns exact a toll on the landing troops, but the US troops overwhelm the defenses and Lae is secured by July 12th. A coordinated para-drop into the moutains near Wau cuts off the Japanese retreating from Lae, which are surrounded and then sacrifice themselves in a futile banzai charge.
simultaneous with the invasion of Lae, light infantry forces are landed on the western end of New Britain. it is determined that the sites have potential for host airfields that can be used for the reduction of Rabaul.
The speed and aggressivness of the Allied advance seems to have take the Japanese off-guard. Recons over Madang show it is lightly defended, and altho initially planned for August, the invasion of Madang is pushed up to the last week of July. Navy CBs are landed at Lae to quickly bring the airfield back into action, and to expand the AF as quickly as possible. The invasion fleet heads for Madang and is intercepted by 2x IJN submarines, who manage to sink a pair of transports before being driven off (no sub kills confirmed). The invasion TF is now spotted, and 120 miles from Madang. Approximately 150x P-38s and Beufighters are scrambled to provide top-cover for the invasion. The Japanese do not disappoint, and sorty several carriers (about 4 - 6?) to attack the invasion TF at Madang.
The veteran P-38s and Beus prove capable at defending their charges - for the loss of 35x allied fighters, 160x enemy aircraft are destroyed, and the TF suffers not a single hit. Altho the theat of a night attack by surface units remains, the threat never materializes, and the landings proceed unmolested. The small garrison at Madang is quickly overwhelmed, and US Engineers quickly go about improving the air-field.
Closing the books on July, the Alies have made major gains in New Guinea, having "rounded onto the northern spine" of New Guinea, and occupied bases in New Britian which can be used for the reduction of Rabaul.
