Dead, and burned beyond recognition — that’s how a South Korean search crew found two people a day after the shelling of Yeonpyeong Island 10 years ago on Nov. 23, 2010. The incident shocked and enraged South Koreans, particularly because it had resulted in the deaths of innocent civilians.

“We never thought they would attack civilians,” Hong Kwang-sun, who saw the men disappear behind a wall of flames as he and other construction site workers ran to take shelter, told The New York Times. “Next time, we should repay them by shooting back.”
