20-28 February 1945
The Beach Party of this ship was landed on BLUE Beach ONE  on the morning of DOG day plus one for services on YELLOW Beach TWO. Upon arrival  relieved the Beach Party of the USS MIFFLIN. The Beach Party  remained on YELLOW Beach TWO for a period of four days and nights  attending and evacuating casualties, salvaging broached boats and  attempting to clear the beach for the landing of boats. Due to the surf  conditions and nature of the terrain, little progress could be effected  in clearing the beach for use by landing boats. The beach at the water's edge  was almost completely blocked with bogged down amphibious tanks, LVT's, vehicles, and  broached boats. By the fourth day clearing had been effected to permit a  slow flow of cargo to be landed. The entire four days on the beach were spent  under enemy mortar and artillery fire, resulting in 1/3 (16) of the beach party  becoming casualties (13 wounded, 2 dead, 1 missing).
 
During the operation twenty-two LCVP's, two LCM's. one  LCP(R) equipped as a salvage boat, and one LCP (L) equipped as boat group  commander and control boat, were used. Ship's boats which were loaded with cargo  were not allowed to land. This was high priority cargo and cargo  called for from the beach as being urgently needed. Some of the boats  were in the water with a load of urgently needed cargo for four days before finally  being permitted to land.
 
During this time they returned to the ship each morning  for fuel and a change of crew and went immediately back to the beach. Three LCT's and one  LSM were employed at various times after DOG plus four in unloading  general cargo. In this connection, it is recommended that a sufficient number  of LCT's and LSM's be provided to unload all cargo. Twelve LCVP's were launched  from Welin davits, all other boats were lowered by cargo booms. As much  cargo as possible was preloaded. All davit boats were loaded at the rail, main  deck, with debarking troops. All boat engines were Gray marine and  operated without failure. The LCM(3) ramp winches failed frequently, necessitating  time out for repairs. Eight LCVP's were lost, one due to gun fire,  three were flooded and sunk at the beach and four broached.
 
Of the seven beaches, the right flank marker of RED Beach  TWO was the only beach limit marker visible for ten days. This caused unnecessary  confusion among boat coxswains, and resulted in some cargo being  landed on the wrong beaches. BLUE Beach ONE had cargo unloading  point markers until DOG plus nine.
 
Preparation for handling casualties consisted of the following       {1 ) A reception center was set up in the troop officer's berthing compartment       with facilities for cleansing and minor surgery. (2) The wardroom       was used as a cleansing and shock treatment center. (3) The main       sick bay was used for maj or surgery and major dressings where anesthetics       were required. The majority of bed patients were cared for in the troop officer's berthing       compartment, the more serious cases in sick bay, and the ambulatory       in the forward troop berthing compartment on the main and third       decks. Casualties were brought aboard one at a time by a six foot boom rigged amidships       main deck. This method proved highly satisfactory both from a standpoint of       speed and of causing least discomfort to casualties. Of the 365 casualties treated, 6       died, 27 were transferred to hospital ships,       and 12 were returned to duty. The remainder were transferred to US Naval Hospital No. 111 at       Guam.
 
With the exception of two nights spent at the objective,  the LOWNDES took part in night retirement to the east, returning to the transport area each morning. At  about 2130 on the night of 27 February 1945,  while anchored near the beach to unload cargo, about eight bursts of  mortar fire from the island fell about 25% off the starboard bow at about 600 yards distant, but the ship was  not hit.
