As soon as it was sufficiently dark, Grayburn led his platoon along the ramp to the bridge, their faces blackened and their boots muffled with strips of torn up curtains. The platoon moved forward on either side of the girders along the sides of the road, but was quickly spotted by enemy forces on the bridge. Grayburn was shot in the shoulder but continued to press his men on, until the withering enemy fire became too intense and he was forced to pull them back. He was the last person to descend from the ramp into cover.
