The Japanese had evidently not expected a landing at Lugos and their positions there were quickly overrun. The 1st Squadron, 8th Cavalry then advanced eastward until it was stopped by a Japanese bunker complex on the edge of the Lorengau airstrip. An artillery barrage was brought down, followed by an airstrike by P-40 Kittyhawks with 500 pound bombs. The cavalry resumed its advance, and occupied a ridge overlooking the airstrip without opposition. In the meantime, the 7th Cavalry had been landed at Lugos from the LST on its second trip and took over the defence of the area, freeing the 2nd Squadron, 8th Cavalry to join the attack on Lorengau. The first attempt to capture the airstrip was checked by an enemy bunker complex. A second attempt on 17 March, reinforced by the 1st Squadron, 7th Cavalry and tanks, made good progress. The advance then resumed, with Lorengau itself falling on 18 March.
