General Krueger was gravely concerned about the seriousness of the situation on Los Negros. In response to urgent request from General Chase, Krueger arranged with Admiral Barbey for the movement of the rest of the 1st Cavalry Division to be expedited. At Krueger's request, the 2nd Squadron, 7th Cavalry would travel in the three APDs. Other units would arrive on 6 and 9 March instead of 9 and 16 March. Krueger realised that Hyane harbour was too small to support the entire division, but there were good beaches around Salami Plantation on the western shore of Los Negros. To use them, and to permit a shore-to-shore operation against Manus from Los Negros, Seeadler Harbour would have to be opened up.
