The battle of Uijeongbu was the battle were the ROK 7th Infantry Division, defending the division line, had to fight against the NKPA 1st Corps (the 3rd & 4th Divisions) around Dongducheon, Pocheon, and Chukseokryeong during the first two days of Korean War. The NKPA forces infiltrated the division line, backed up by the NKPA 105th Brigade.
At this battle, the ROK 7th Division came under attack of the NKPA forces at June 25 and pulled back to Pocheon and Dongducheon after losing its position around the division line to the enemy. Then the ROK 7th Division was in a hurry to establish a defense line but have no choice but to withdraw to Uijeongbu after hitting hard by the North Korean tank units. The 7th Division launched a counterattack on the North Korean forces with the support of the ROK 2nd Division and the Capital Security Headquarters but was forced to retreat to the Changdong line in the afternoon of June 26, 1950.Uijeongbu, the gateway to Seoul, fell into the hand of the KNPA forces through this battle. So the ROK forces made its utmost in order to seek a strong measure to defend Seoul. The NKPA forces halted its offensive in Uijeongbu and began guarding itself for the operation for invading Seoul.
2) Munsan Battle (June 35~28, 1950)
The ROK 1st Infantry Division fought a defensive battle with the support of the two attachment infantry units against the 1st & 6th NPA Divisions which were backed by a T-34 tank regiment around Gaesung, Munsan, Papyeong Mt., and Bongil-cheon(stream) for four days.In this battle, the 1st ROK Division deterred the KNPA forces from advancing south by using natural obstacles from the Imjin river and Gokryeungcheon but had to retreat to Siheung, crossing the Han river, because the withdrawal route was blocked after the North Korean forces took Seoul on June 28. However, the ROK 1st Division missed a chance to retreat and suffered a heavy loss because it had to abandone all crew-served weapons and the personnel disintegrated by the lack of the equipment for crossing the river. This battle enabled the North Korean forces to occupy the north part of Hansu. Thus the ROK forces had many difficulties in establishing a defense line around the Han River.

The newly-arrived Smith Task Force of the U.S. 24th Division 21st Regiment fought a defensive battle against the two regiments of the North Korean 4th Division and one tank regiment that were advancing south around Jukmiryeong.

This battle let the KNPA forces know the U.S.¡¯ entry into the Korean War and let the U.S. forces get a grip on the strength of the North Korean forces.
4) Dongrak-ri Battle (July 5~10, 1950)
The ROK forces in the west line congregated at Pyenontaek and Anseong after the defense line of the Han River was destroyed. The 7th Regiment of the ROK 6th Infantry Division moved south toward Chungju from Wonju along the axial line of the road No. 3 (Icheon-Janahowon-Chungju) and went toward Janghowon in order to deter the 15th KNPA Division from advancing south. The 7th ROK Regiment defeated the KNPA leading troop?the 48th North Korean Regiment?and delayed the enemy¡¯s advancement to the south. The ROK forces achieved the greatest victory after the war in this battle, and which led to delaying the North Korean forces¡¯ advancement to Eunseong for one week. So the ROK forces were able to establish the defense line and rearrange the battle line.
5) The Incheon Landing Operation (September 15~16, 1950)
The Incheon Landing Operation was initiated by the UN forces and the ROK forces after deterring the KNPA forces¡¯ offense between August and September.

The UN forces successfully implanted the landing operation within one month by overcoming the natural disadvantage of the Incheon harbor such as the high tide (up to 10.3m) and the narrow channel. The success of the landing operation facilitated the UN forces¡¯ all-out counterattack operation.
6) Jeokseong Battle (April 22~25, 1951)
Confronting the first spring offensive of the CCF, the 29th British Commonwealth Brigade and the Belgium attachment battalion delayed the attack of the CCF around the Imjin River (Jeokseong-Dogampo).

The 27th British Commonwealth Brigade took up a position around the Gapyeong-cheon(stream) and blocked the CCF. The 20th CCF Corps could not cross the North Han River in the south of Gapyeong when it was implementing the first spring offensive. Therefore the ROK and UN forces could get leeway for establishing a new defense position on No-name Sun.

The 45th U.S. Division, which took up a defense position around Cheondeok Mt., occupied 11 outpost positions including Bulmo Hill on the forward of the main resistance line in order to secure the defense depth. When the 45th Division came under attack from the three divisions of the CCF Corps, it successful defeated the CCF forces with the support of the 2nd U.S. Division on Bulmo Hill, which is one of the advance positions. Both sides suffered a heavy loss because they even fought hand to hand as well as engaged in a massive fire operation. This battle served as an opportunity for the CCF to recognize the strong fire power of the U.S. forces, and for which in return to reevaluate the so-called human wave tactics of the CCF.
11) Goyangdae Battle (September 6 ~ December 13, 1952)

At that time the 1st ROK Division, which took up its position on the upstream of Imjin River, fought a defensive battle with the 47th CCF Corps on the outpost positions (Nicky Hill, Tecy Hill, Nori Hill, Betty Hill) around Goyangdae. At this battle which began at fall and continued on winter, the 1st ROK lost Nicky and Tecy Hills at the beginning but secured Betty Hill and Nori Hill.

The 5th Marine Regiment of the 1st U.S. Marine Division launched a defensive battle against the CCF 120th Division which invaded the outpost position of the 5th Marine Regiment while it was defending the Nevada outpost area (Vegas/Leno/Carson outposts) on the northeast of Panmunjeom. The 5th U.S. Marine Regiment lost Vegas outpost and Leno outpost after coming under attack of the CCF on March 26. It launched a counterattack with the support of one battalion of the 7th Marine Regiment, artillery units, and air force.
