numerous reefs, sand banks, and mangrove swamps of the island's coast offered few suitable landing sites. Farther inland, the coastal plain gave way to heavily forested mountains that offered great defensive potential to Japanese forces. The 186th Regimental Combat Team of Brig. Gen. Harold H. Haney—the assistant 41st Division commander—was the principal combat unit entrusted by Gen. Doe to carry out the Palawan invasion. A naval task force of cruisers and destroyers from the 7th Fleet under Vice Admiral Thomas C. Kinkaid—which was Gen. Macarthur's naval command—would protect the landing forces on their movements to shore and then remain to provide gunfire as needed. Troops and supplies would be actually carried by elements drawn from a 7th Fleet component command, the VII Amphibious Force under Rear Adm. Daniel E. Barbey. The Palawan landings were to be undertaken by the assigned amphibious task force of Rear Adm. William M. Fechteler. Battle After two days of punitive air strikes by the U.S. 13th Air Force and a fierce naval bombardment by 7th Fleet warships offshore, the first assault wave from the 186th Regimental Combat Team began moving ashore at Puerto Princesa on the morning of 28 February, under the eyes of Gen. Eichelberger, who watched from a B-17 heavy bomber flying overhead. As expected, the absence of suitable landing areas slowed the largely unopposed unloading operation, but the process would have been even slower if not for the outstanding efficiency of the Army Shore Party and Boat Company from the 2nd Engineer Special Brigade, units who ably supervised and managed the movement of troops and supplies at the beach landings. The men of the 186th RCT quickly fanned out, with two battalions striking north along the eastern side of Puerto Princesa Harbor while a third battalion crossed the bay at its midpoint and then pushed north, but then as the first day progressed, it became clear to the invading American troops that the Japanese troops—holdovers from Lt. Gen. Sōsaku Suzuki's 35th Army—would not put up a fight at Puerto Princesa and had withdrawn into the hills to the northwest. More disturbing was the revelation of a massacre of approximately 150 American prisoners of war the previous December. The presence of a passing Allied convoy made the alarmed Japanese believe that an invasion was imminent and had herded their prisoners into air-raid shelters, subsequently setting the shelters afire and shooting prisoners who tried
