Concurrent with the Battle of the Ch'ongch'on River was the Battle of Chosin Reservoir, which the PVA 9th Army Group initiated on 27 November. Here the UNC forces fared comparatively better: like the Eighth Army the surprise attack also forced X Corps to retreat from northeast Korea, but they were in the process able to breakout from the attempted encirclement by the PVA and execute a successful tactical withdrawal. X Corps managed to establish a defensive perimeter at the port city of Hungnam on 11 December and were able to evacuate by 24 December in order to reinforce the badly depleted U.S. Eighth Army to the south. During the Hungnam evacuation, about 193 shiploads of UN Command forces and matériel (approximately 105,000 soldiers, 98,000 civilians, 17,500 vehicles, and 350,000 tons of supplies) were evacuated to Pusan. The SS "Meredith Victory" was noted for evacuating 14,000 refugees, the largest rescue operation by a single ship, even though it was designed to hold 12 passengers. Before escaping, the UN Command forces razed most of Hungnam city, especially the port facilities. On 16 December 1950, President Truman declared a national state of emergency with Presidential Proclamation No. 2914, 3 C.F.R. 99 (1953), which remained in force until 14 September 1978. The next day, 17 December 1950, Kim Il-sung was deprived of the right of command of KPA by China.
