BISMARCK ARCHIPELAGO: After preparatory naval gunfire and aerial bombardment, during which Japanese observation from Target Hill, commanding the landing beach, is masked by smoke, Task Force BACKHANDER, commanded by Major General William H. Rupertus, Commanding General 1st Marine Division, and consisting of the 1st Marine Division (--), reinforced, begins the main invasion of New Britain at Cape Gloucester at 0746 hours.
The Marines are landed by the Seventh Amphibious Force under Rear Admiral Daniel E. Barbey. Forested, swampy terrain is more formidable than the surprised Japanese, who offer only light opposition. The 7th Marine Regiment establishes a beachhead, clearing. Target Hill, and is passed through by the 1st Marine Regiment. General Rupertus establishes his command post ashore. Successful secondary landings are made by the reinforced 2d Battalion, 1st Marine Regiment, at Tauali, southwest of the airdrome, and by elements of the 2d Engineer Special Brigade on Long Island. A Japanese force reaches positions northwest of the Arawe main line of resistance.
During retaliatory Japanese air strikes on Cape Gloucester, USN destroyers USS Lamson, Shaw, and Mugford are damaged by dive bombers; and tank landing ships USS LST-66 is damaged by a horizontal bomber. USN destroyer USS Brownson is escorting landing craft during the landings at Cape Gloucester. At about 1442 hours local, Brownson is hit by two bombs from a Japanese "Val" dive bomber.
The bombs strike to starboard of the centerline, near number two stack. A tremendous explosion follows and the entire structure above the main deck as well as the deck plating, is gone. The ship lists 10 to 15 degrees to starboard and settles rapidly amidships with the bow and stern canted upward.
The wounded are placed in rafts and at 1450 hours the order to abandon ship is given. The amidships section is entirely underwater at that time. There is a single ripple like depth charge explosion and the ship sinks at 1459 hours about 6.5 nautical miles N of Cape Gloucester in position 05.20S, -148.25E. One hundred eight of her crew are lost.
Supporting the landings, over 270 USAAF Fifth Air Force B-25s. B-24s, and A-20s attack the area between the Cape and Borgen Bay from 0714 to 1614 hours.

McGuire, Jr., flying a P-38H, shoots down three "Val" dive bombers over the invasion beaches. He cuts cards with a second pilot for the credit for shooting down a fourth "Val" and loses. McGuire now has 16 victories.
