The Korean incident couldn't have happened at a more opportune time, what with the entire 3rd Bomb Wing, 339th Fighter Squadron (AW), and the 68th Fighter Squadron (AW), staged at Itazuke Air Base and Ashiya Air Base.

June 25: North Korea invaded South Korea. Simultaneously, North Korean troops made an amphibious landing at Kangnung on the east coast just south of the 38th parallel. North Korean fighter aircraft attacked airfields at Kimp'o and Sŏul, the South Korean capital, destroying one USAF C-54 on the ground at Kimp'o.
John J. Muccio, US ambassador to South Korea, relayed to President Harry S. Truman a South Korean request for US air assistance and ammunition. The UN Security Council unanimously called for a cease-fire and withdrawal of the North Korean Army to north of the 38th parallel. The resolution asked all UN members to support the withdrawal of the NKA and to render no assistance to North Korea.
Maj. Gen. Earle E. Partridge, who was commander, 5th Air Force, but serving as acting commander of Far East Air Forces (FEAF), ordered wing commanders to prepare for air evacuation of US citizens from South Korea. He increased aerial surveillance of Tsushima Strait between Korea and Japan. The 20th Air Force placed two squadrons of the 51st Fighter-Interceptor Wing (FIW) on air defense alert in Japan. [note]

On the east coast across the high Taebaek Range from Inje, the last major concentration of North Korean troops awaited the attack hour. There the NKPA 5th Division, the 766th Independent Unit, and some guerrilla units were poised to cross the Parallel.
On the south side of the border the 10th Regiment of the ROK 8th Division held defensive positions. But not quite, the division was scattered all over South Korea.
The ROK division headquarters was at Kangnung, some fifteen miles down the coast; the division's second regiment, the 21st, was stationed at Samch'ŏk, about twenty-five miles farther south. Only a small part of the 21st Regiment actually was at Samch'ŏk on 25 June, however, as two of its battalions were engaged in anti-guerrilla action southward in the Taebaek Mountains. [03-35]
The division's 3rd regiment the 16th was assigned to the ROK 2nd Division at Taejŏn at this time.
Meanwhile, two battalions of the 766th Independent Unit had landed near Kangnung. Correlating their action with this landing, the NKPA 5th Division and remaining elements of the 766th Independent Unit crossed the Parallel with the 766th Independent Unit leading the attack southward down the coastal road.
