BISMARCK ARCHIPELAGO: Operation DEXTERITY opens when, as a preliminary to the main invasion of New Britain Island, USN Task Force 76 (Rear Adm Daniel E. Barbey) lands Task Force DIRECTOR, the 112th Cavalry Regiment (Special) reinforced under command of Brigadier General Julian W. Cunningham, USA, on the coast of Arawe Peninsula about 0700 hours local, after naval gunfire and aerial bombardment. Scattered opposition on the peninsula is overcome without difficulty. Before the main landing, cavalrymen try in vain to make surprise landings at Umtingalu, on the mainland east of the peninsula, and on Pilelo islet.
Despite alerted Japanese forces, Troop B succeeds in landing on Pilelo and quickly clears it. Japanese planes are active against troops and shipping, attacking at frequent intervals during this and the next few days. Plans to use Arawe as a base for light naval forces never materialize, nor is the site used as an air base. The plan for the Cape Gloucester landing is amended to increase the size of initial assault force and limit the objective of the secondary landing.
