The amphibious element boarded amtracs and moved out at 0500 on February 23. Fifty-four amtracs from the 672nd Amphibian Tractor Battalion set out across Laguna de Bay from Mamatid, their noisy engines giving notice that the attacking force was on its way. In the pitch-black, pre-dawn darkness, a lack of landmarks forced the tractor drivers to navigate solely by compass.
At Nichols Field outside Manila, the paratroopers boarded nine C-47s at 0530. Half an hour later, the pilots started their engines. After takeoff, each of the jump planes orbited over the field until all nine were airborne and had joined the formation. At 0640 the C-47s headed southeast over Laguna de Bay toward Los Baños. Fifteen minutes later, the pilots signaled a six-minute warning by turning on the red paratrooper jump lights in the cargo compartments of their airplanes. At 0700 Ringler stepped from the door of the lead C-47; the Los Baños raid was in progress.
