As she backed off the beach again, she was holed by a mortar round and began taking on water. Meanwhile, the damaged PT had reported what had happened and a bomber was sent to investigate. Flying low, it spotted the men in the water, and another PT boat was sent to the rescue, covered by the destroyer . After three hours in the water, the LCVP's survivors were picked up by the PT boat. Eight Americans, including Major Vaden, had been killed and fifteen wounded, including the entire LCVP crew. Kaihu was missing and Robinson was contemplating how he would break the news to his family when Kaihu walked in, having swum back to Los Negros. General Swift postponed the landing on Lugos and ordered the 2nd Squadron, 7th Cavalry to capture Hauwei. Once again, Robinson acted as guide, notwithstanding severe sunburn from his time in the water the previous day. The landing was covered by the destroyers "Arunta", "Bush", "Stockton" and ; a pair of rocket-firing LCVPs and the LCM (flak), which fired 168  rockets; the guns of the 61st Field Artillery Battalion on Los Negros; and six Kittyhawks of No. 76 Squadron dropped bombs. The assault was made from three cargo-carrying LVTs. To save wear and tear, they were towed across Seeadler Harbour by LCMs and cut loose for the final run in to shore. The cavalrymen found well constructed and sited bunkers with interlocking fields of fire covering all approaches, and deadly accurate snipers. The next morning an LCM brought over a medium tank, for which the Japanese had no answer, and the cavalrymen were able to overcome the defenders at a cost of eight killed and 46 wounded; 43 dead Japanese naval personnel were counted. The 61st and 271st Field Artillery Battalions moved to Hauwei, while the 99th established itself on Butjo Luto. The attack on Manus got underway on 15 March. Before dawn, two troops of the 8th Cavalry, six cargo carrying LVTs and the combat LVT were loaded on board an LST for the trip across Seeadler Harbour from Salami. Beaches at Lugos, about west of Lorengau were chosen in preference to those nearer Lorengau, which were known to be heavily defended. The destroyers , , , and bombarded the area with their 5-inch guns; the two rocket LCVPs, the LCM (flak), and the combat LVT raked the shoreline with rockets; the artillery on Hauwei and Butjo Luo engaged targets; and 18 B-25s of the 499th and 500th Bombardment Squadrons dropped 81  bombs and strafed the area.
