We have landed in the Admiralty Islands which stand at the northern entrance to the Bismarck Sea almost due south of Guam and 1,300 miles from the Philippines. . . . This marks a final stage in the great swinging move pivoting on New Guinea which has been the basic purpose of the operations initiated on June 29, 1943, when the Southwest Pacific area and South Pacific Area were united under General MacArthur's command. The axis of advance has thereby been changed from the north to the west. This relieves our supply line of the constant threat of flank attack which has been present since the beginning of the Papuan Campaign. This line, previously so precariously exposed, is now firmly secured not only by air cover, but by our own front to which it is perpendicular. Tactically it tightens the blockade of the enemy's remaining bases. Their supply lines are definitely and conclusively severed and only a minimum of blockade running, by submarine or individual surface craft, is now possible. In addition to the troops trapped in the Solomons, some fifty thousand of the enemy, largely in New Britain and at Rabaul, are now inclosed. Their situation has become precarious and their ultimate fate is certain under blockade, bombardment and the increasing pressure of besieging ground forces. The end of the Bismarck Campaign is now clearly in sight with a minimum of loss to ourselves.
