With the United Nations forces moving up the 38th parallel, Wonsan a major North Korean seaport is captured by the ROK I Corps on October 10th, 1950.
Wonsan Harbor was a prime target for the United States Navy. Its harbor was kept out of use by communist forces, even after they took back Wonsan in the aftermath of China’s intervention into the Korean War. As a result, the longest siege of any port in modern times was conducted by the 7th Fleet, lasting for 861 days. The siege involved the IOWA alongside many other components of the United States Navy and its assets, holding the communist forces at bay, and ultimately helping to end the war in an armistice.
