The first US troops landed on the Island at 9:10 on the 18th, coming ashore from their LCVPs on the south western side of the island near the jetty; they were followed at five minute intervals by the other five waves. Shortly after landing, the U.S. troops came under heavy fire from concealed positions. The fire, however, was predominantly aimed at the LCI gunboats and ultimately the Americans reached the beach with only light casualties. By 9:25, the invasion force was ashore with two tanks (one of the others had been lost at sea, while the other had damaged during loading) which the Americans used to secure the beachhead, despite heavy fire from Japanese defenders which killed one of the company commanders. Close air support was provided by a squadron of A-20 attack aircraft, under the direction of a controller in a B-25.
