As the soldiers escape, the Americans ambushed them, intending to take the women alive, Big Daddy sacrificed himself and Wenjun died.

As the bombardment upon the American-occupied hills ends, they charged with human waves, suffered casualties, but after they placed artillery, they repelled the defenders.

[1] The film was not well received in the Republic of Korea, and was considered controversial in mainland China, in part due to its promotional material.

The controversial advertisement depicted a South Korean tour guide in Seoul, shown as being ignorant if China's involvement in the Korean War, being bombastically lectured by patronizing elderly veterans of the events depicted in the film, boasting of their involvement in the invasion of Korea as they recommend the film to her so she might be better "educated" as to what they are taking about.
