I first saw this photo at the Korean War Children's Memorial website.
The photo's caption sheds some light on the similar film and photos. According to photographer PFC Ronald L. Hancock,
Sfc Barnes, a. Motion Picture Cameraman and I were looking through Inchon, Korea for pictures when we saw some marines detaining some North Korean POW's. As we started to take picture, we heard a child crying and saw a better picture. The results appear in this picture, which I call "All Alone."The Chosun Ilbo has some newly released photos from the Korean War, as well as some released last year; among the latter, the first photo reminded me of a passage by Reginald Thompson of the London Daily Telegraph quoted in the book Korea Witness, which perfectly described the photo. One detail is different, however, making it clear that such a scene repeated itself many times throughout the war.
I'm quite certain the second photo in this set was taken at the same time as this photo from this post, just before the first and fifth marine corps split up, the first moving through what is now Bucheon towards Yeongdeungpo, the fifth moving towards Kimpo Airport, and the neighbourhood I live in at the moment. I'll post about that in the next day or so.
