At 0200, B Company's turn came. A truck stopped at the bottom of the hill, a whistle sounded, then came a shouted order, and enemy soldiers started climbing the slope. The hills on both sides of B Company were already under attack as was also Hill 311, a rugged terrain feature a mile and a half back from the river and apparently the enemy's principal immediate objective. The North Koreans apparently were not aware of the Task Force Manchu group lower down on the hill for it remained unmolested during the night. But higher up on Hill 209 the enemy drove B Company from its position, inflicting very heavy casualties on it.
