A protective wall, from the inside, with lake or river in the background. In China during WWII.
Among the images collected by the editors of Ex-CBI Roundup (through reader submission), and shared with the Remembering Shared Honor project, were a series of images provided by Dorothy Yuen Leuba. Because of her travels over an extended time in China, her photos include a sprinking of locations across China, both north and south.
A short biography for Mrs. Leuba can be seen here.
