Early that morning, the diversionary force of the 188th Glider Infantry Regiment and Company C of the 637th Tank Destroyer Battalion, together with elements of the 472nd and 675th Field Artillery Battalions under Soule, rolled out into Highway 1 and attacked across the San Juan River. They ran into Japanese opposition near the Lechería Hills where casualties were taken, but by mid-morning they had cleared the area and were marching towards Los Baños and cutting off the road between the Japanese 8th Tiger Division and Los Baños.
