We had a family friend who was there. He had 90+ people (non combat personell and the like) that he had to get out by walking. He caried people and had to threaten to shoot some to keep them moving. We must never forget.
A friend of mine was there. And the father of another friend. One a Marine, the other a Chinese from Beijing. It's kind of strange. The Marine has respect for the Chinese soldier in Korea. The Chinese was a volunteer helping out his Korean cousins. Both highly competent and honorable human beings. 20 below, the ubiquitous Marine howitzers firing to all four points of the compass, no transport, facing each other as enemy soldiers, both doing their duty. That's all that can be done.
