Air Operations, New Guinea

• At first light, in support of US Army landings at Bosnik on Biak Island, 12 XIII Bomber Command B-24s based in the Admiralty Islands attack beach defenses. At 0700, 25 XIII Bomber Command B-24s supplement naval gunfire when they also attack beach defenses at Bosnik.

• Between 1103 and 1150, 77 V Bomber Command B-24s attack Biak�s three airfields�Sorido, Mokmer, and Borokoe. Scheduled attacks by 348th Fighter Group P-47 fighter-bombers are suspended in the face of bad weather between Hollandia and Biak, and no USAAF fighter appears over Biak until after 1100 hours. Nevertheless, throughout the day, V Bomber Command B-25s and A-20s mount scheduled strikes and provide on-call support for the ground troops, and V Fighter Command fighters are available from 1100 hours on. Throughout the day, 1 A-20 is lost to ground fire.
• Beginning at 1100 hours, small flights of Japanese fighters and bombers attack the Biak invasion fleet with negligible results. One burning twin-engine bomber inadvertently strikes a USN submarine chaser, killing two and injuring eight crewman, and starting fires that are soon quenched.

Burma-China

In the Myitkyina area 2 Chinese-American battalions are engaged in hard fighting with Japanese units south of Charpate, trying to get to Radhapur. They do not reach their objective and suffer heavy losses.

On the Salween River front Chinese troops get within 5 miles of Hongmoshu. The monsoon rains limit operations by both sides.

The Japanese advance with 2 divisions in the region east of the Hsiang River, in south China.

Italy

Artena is held by 3rd Div despite German counterattacks. Units of the 88th Div reach Roccagorga and farther north the French capture Amaseno, Castro dei Volsci and Monte Siserno.

In the 8th Army sector in the Liri Valley Canadian units attack Ceprano and the British 6th Arm Div moves toward Arce supported by the 8th Indian Div.

New Guinea

US Forces land on Biak Island in the Schoutens group, 150 miles nortwest of Wadke in the big Geelvink Bay and 900 miles from the Philippines. There is the usual preliminary bombardment, in this case by cruisers of Rear-Adm William Fechteler's squadron, before the men of 41st Inf Div under Gen Horace Fuller land near Bosnek. At first there is little resistance but this is misleading, for the Japanese garrison at 11,000 men(Col Kazume) is little weaker than the attack force. The close escort for the landing ships is provided by cruisers and destroyers led by Adm William Fechteler and as in the other landings on the north coast Adms Victor Crutchley and Russell Berkey are in support. PT-339 is sunk by US forces after being damaged running aground in western New Guinea.

In the Wadke-Sarmi area the US 158th Inf progresses very slowly, winning a few positions. The Japanese launch a series of attacks against the perimeter of the beachhead during the night. They attack at least 200 times along the whole perimeter, but are repulsed.
