Watch Free Online HD Moviesjoy. The Forgotten War: Colombia’s Battalion in Korea is a documentary that brings to light the little-known story of Colombia’s involvement in the Korean War (1950–1953). Through personal testimonies, rare archival footage, and geopolitical analysis, the film recounts how over 5,000 Colombian soldiers, organized as the Colombia Battalion No. 1, answered the United Nations’ call to support South Korea against the invasion by the North, which was backed by China and the Soviet Union. This marked Colombia’s first international military mission and the only Latin American combat presence in the conflict. Though long overlooked, this intervention laid the foundation for a “special” bilateral relationship between Colombia and South Korea that endures to this day.
