Sep 15, 1950 #KoreanWar UN forces landed in force today behind the Communist lines on both east and west coasts of Korea. The main landing was at Inchon, on the west coast. By this evening the Americans had driven 12 miles inland to within 10 miles of Seoul. They seized Kimpo airport, south of Seoul. General MacArthur planned the giant amphibious operations, inspected the beaches at Inchon, and directed the landing there.
More than 100 Korean War veterans were honored Monday during a ceremony on the 75th anniversary of Operation Chromite, the daring amphibious assault that turned the tide for South Korea and the US-led UN Command. South Korean, American and Australian veterans made a pilgrimage to Incheon Port. https://www.stripes.com/veterans/2025-09-15/korean-war-incheon-landing-anniversary-19096813.html

General MacArthur's son, Arthur MacArthur IV, has issued a rare statement to mark the 75th anniversary of the Incheon Landing.
Sep 17, 1950 #KoreanWar Observers believe that the fall of Seoul to United Nations forces is imminent. Some of these forces to-night had advanced to the city's outskirts, and were reported to be battling in the suburbs. General MacArthur, who is personally directing the main offensive, today stepped ashore at Inchon and headed for the front lines. Looking down on the bodies of four Communists on the Allied Inchon beachhead today, General MacArthur said: "That's a good sight for my old eyes."
Sep 21, 1950 #KoreanWar US Marines began an all-out assault on Seoul, capital of Korea, late this afternoon. Marines are already in the outer suburbs to the north and south. In Washington to-day, President Truman said he would abide by any United Nations decision whether Allied troops should cross the 38th parallel into North Korea.
Sep 21, 1950 #KoreanWar The United Press correspondent on the Inchon front says that the column of Communist reinforcements came from the Manchurian city of Antung, just over the border at the northwestern tip of Korea. There is no indication, however, whether these troops are North Koreans or Chinese Communists. The column has reached Kaesong, only 35 miles north of Seoul.
Sep 24, 1950 Battle for "Little Stalingrad". The big push for Seoul has begun American Marines, fighting on the fringes of the city's western suburbs, are confident they will enter the city itself within a matter of hours. More Marines are crossing the Han River and are moving up to the front line.
Sep 27, 1950 No doubt appeared to exist among the delegates or UN Secretariat officials that the 38th parallel could no longer arbitrarily divide Korea as it did before the Northern aggression. However the decision whether the UN forces should cross the 38th parallel has been delayed.
Sep 29, 1950 #KoreanWar In a colourful ceremony here today General MacArthur restored to President Syngman Rhee the capital city Seoul and seat of government of the South Korean Republic. South Korean forces racing up the east coast reached the 38th parallel late this afternoon, according to air observers.
Sep 29, 1950 #KoreanWar I KNOW that I speak for the entire American people when I send you my warmest congratulations on the victory which has been achieved under your leadership in Korea. Few operations in military history can match either the delaying action where you traded space for time in which to build up your forces, or the brilliant maneuver which has now resulted in the liberation of Seoul. I salute you all, and say to all of you from all of us at home, "Well and nobly done." President Harry S Truman

Message Congratulating General MacArthur on the Liberation of Seoul | Harry S. Truman

September 29, 1950

Sep 30, 1950 #KoreanWar General MacArthur receives this message from Secretary of Defense George C. Marshall. This message is known as the "blank check." It instructs MacArthur to feel "unhampered tactically and strategically to proceed north of 38th parallel.” It also informs him that the UN does not want to vote on this expansion of the Korean War, but would rather sanction it after the fact. https://www.macarthurmemorial.org/483/Korean-War-Messages
Sep 30, 1950 #KoreanWar The South Korean Government at Pusan said today that the South Korean National Assembly had decided unanimously to ask the UN General Assembly for authority to send the South Korean armies across the 38th Parallel. There was speculation, however, that the Allies might serve a formal surrender ultimatum on the North Koreans before crossing the old frontier.
Oct 2, 1950 South Korean troops on Korea's east coast today smashed through Communist defences along the 38th parallel and swept into North Korea on a broad front. On the west coast, US Marines are moving up slowly to the 38th parallel above Seoul. The North Koreans have not replied to General MacArthur's broadcast demand for surrender.
Oct 3, 1950 #KoreanWar Russia put before the UN her plan for ending the war in Korea and would introduce another resolution calling on the UN General Assembly to halt the "inhuman bombings of peaceful populations by American planes." It calls for an immediate cease-fire and the withdrawal of all UN troops.
Oct 3, 1950 #KoreanWar The President of South Korea Dr Syngman Rhee said he saw no need for new elections in Korea. That UN forces must occupy all of Korea if any future war in Korea is to be avoided. "The restoration of the arbitrary boundary of the 38th parallel would leave intact the conditions which provoked this war."
Oct 3, 1950 #KoreanWar An American reconnaissance pilot reported today that a truck convoy "100 miles long" and including artillery is moving from Manchuria to North Korea. Earlier today a report from Taiwan said that the bulk of the Chinese Communist 4th Field Army had crossed into North Korea. 
Oct 6, 1950 #KoreanWar General MacArthur said yesterday that the Korean campaign was one of the world's decisive battles and gave the Allies another chance to control the destiny of the world. He added that China and Russia would have intervened in Korea before now if they had intended to do so.
Oct 8, 1950 #KoreanWar American sources confirmed tonight that patrols of the US First Cavalry Division yesterday crossed the 38th "parallel into North Korea north of Kaesong". The patrols, the first American troops to cross the border, met no opposition. Other UN forces, including British and Australian troops, are expected to join the Americans soon in a crossing in strength.
Oct 9, 1950 #KoreanWar American, British, and Australian troops this morning launched a full scale drive into North Korea. By tonight the Americans had pushed about two-and-a-quarter miles north of the 38th parallel. Frontline reports say that great streams of tanks, artillery, Bren carriers and trucks are moving along the main road on the southern approaches to Kaeson.
Kaeson marks the spot near Kim Il Sung Stadium where Kim Il Sung delivered his victory speech after the liberation of Korea on October 14, 1945, entitled "Every Effort for the Building of a New Democratic Korea". At that time, the place was called the Pyongyang Public Ground. https://en.wikipedia.org/wiki/Kaeson_Revolutionary_Site

Oct 9, 1950 #KoreanWar The last act of the Korean tragedy has begun. American forces have now crossed the 38th parallel into Communist territory in the wake of South Korean troops. At the same time, General MacArthur, as UN Commander-in-Chief, has issued a final surrender call to the North Korean army.
Oct 11, 1950 #KoreanWar Announcing that he would meet General MacArthur in the Pacific this weekend, President Truman said that he would discuss with the General "other matters" as well as Korea. It will be the first meeting between Mr Truman and General MacAithur, who have never even seen each other.
Oct 12, 1950 #KoreanWar Stalin's message was in reply to greetings which the Prime Minister of North Korea, Kim II sung, sent him on the second anniversary of the establishment of diplomatic relations between Russia and North Korea. According to the Moscow Radio, Stalin said: "I wish the Korean people, who are heroically defending the independence of their country, a successful completion of their long years of struggle for the establishment of a united, independent Korea."
Oct 14, 1950 #KoreanWar General MacArthur today flew from Japan to Wake Island to meet President Truman in a momentous conference which may shape United States policy toward the Far East for years to come. This will be the first meeting between President Truman and his famous general and administrator, who has not visited the United States mainland for 15 years.
Nov 1, 1950 Enemy jet fighters and American Mustangs and jets (F-80) fought an inconclusive aerial battle over Sonchon, North Korea, today. This is believed to have been the world's first aerial battle between jet planes. Reuter says some American officers believe that, the Communist jets were Chinese.
Nov 3, 1950 Communist China is giving every indication of preparing for full scale intervention in Korea, says the Tokyo correspondent of United Press. Thousands of Chinese troops already are fighting the UN forces in Korea, and more are crossing from Manchuria daily, the correspondent adds. The Chinese leaders have not yet told the Chinese people that Chinese troops are in action in Korea.
Nov 4, 1950 The First Division attacked toward the vital Chosin reservoir after breaking the back of the Communist opposition yesterday. In one of the fiercest battles of the war, they forged ahead more than a mile into. Su, 16 miles south of the reservoir. In the first 21 hours, the Marines killed an estimated 800 of a regiment of crack Chinese troops.
Nov 6, 1950 TIME Early in the #KoreanWar US planners had been haunted by the possibility that Communist China might go to the aid of North Korea. But after UN armies broke out of the Pusan perimeter and turned the North Korean retreat into a rout, the planners breathed more easily. China’s chance to strike a decisive blow in the Korean war had passed. https://time.com/archive/6615999/war-late-entry/
Nov 6, 1950 MacArthur announced today that the Communists had moved a fresh army from Manchuria into North Korea. Later, in a special report to UN, he said that his fighting forces were "at present in hostile contact with Chinese Communist. Diplomats at UN Headquarters agree that China's intervention has created an explosive situation which could easily lead to a new world war.
Nov 7, 1950 Mr. Truman, who has gone to his home town of Independence (Missouri) to cast his vote, said there last night that Korea was proof that freedom could survive if the peoples who cherished it stood together. "Free nations must stand together and help one another if freedom is to survive." The President said that the United States in 1920 "ran out" on its responsibility for the preservation of world peace. He apparently was referring to the abandonment of the League of Nations by the United States. "We can't do that this time," he said, "and we are not going to."
Nov 12, 1950 Communist China yesterday flatly rejected last Wednesday's Security Council invitation to take part in its debate on General MacArthur's report on Chinese intervention in the Korean war. The cable said that the Communist Chinese delegation would discuss only Taiwan and "American intervention in Korea."
Nov 14, 1950 The first pilot to shoot down an opposing jet in the world's first jet-versus-jet fighter duel in aviation history tonight said that the Soviet MIG 15 back-swept wing jet, one of which he shot down, is at least 100 miles faster than the American Shooting Star jet which he was flying. He is handsome, 25-years old Lieutenant Russel Brown, of Pasadena.

Nov 30, 1950 #KoreanWar The entire US 1st Marine Division and two regiments of the US Seventh Division are isolated at the Changjin Reservoir. In massed attacks, the Communists swept round the American force and captured Kotori. In some cases the Americans are fighting from behind the heaped bodies of their enemy.
A force of nearly 120,000 Communist Chinese attacked the United Nations (UN) forces, mostly United States Marines, on Nov 27, 1950. The Marines held their position under staggering odds, until given the order to withdraw on November 30, which prompted Maj. Gen. Oliver Smith’s famous response, “Retreat Hell! We’re advancing in a different direction.”

75th Anniversary of Chosin Reservoir – The Picatinny Marines of the Korean War

PICATINNY ARSENAL, N.J. - This Thanksgiving marks the 75th Anniversary of one of the most grueling and hard-fought battles in the history of the military of the United States. A force of nearly 120,000 Communist Chinese attacked the United Nations (U.N.) forces, mostly United States Marines, on Nov. 27, 1950.

Nov 30, 1950 Mr. Truman said that use of the atom bomb in Korea had always been under consideration. Whether it was used was up to American military leaders in the field. He personally hoped, he added, that it would not have to be employed. Mr. Truman added that the bomb could be used without UN approval.
Dec 3, 1950 #KoreanWar Under heavy enemy pressure, Allied forces in Korea continue to yield ground along their defence arc about 30 miles north of Pyongyang, the North Korean capital. The United States will stand firm on its demand that Communist China take its troops out of Korea before any peace negotiations can begin.
Dec 11, 1950 Allied troops claim that in their escape down the mountain corridor from the Chosin Reservoir they killed a large part of three Chinese divisions. When they reached the safety of the Allied perimeter, the troops were hollow-eyed, blood-splashed, and weary to the point of dropping. The men on foot arrived stumbling' and wincing from frostbite, many of them using their rifles as crutches. Some had blood frozen to their skin. The Chinese ambushers were apparently in an almost equally dispirited and weary state.
Jan 15, 1951 TIME SEOUL was all but dead. During the day, occasional bands of laborers trudged off to the north to work on the city’s last-ditch defenses. The rest of the remaining population seemed to be mostly kids. At night, the city lay black, empty and desolate in the moonlight. The crack of small-arms fire rang incessantly through the streets. Seoul’s last-ditch nightspot, the Consolation Club, which advertised “Fifty Beautiful Women Fifty.” Inside, a dozen odd bedraggled beauties gyrated round a scarred dance floor, their swirling Korean skirts revealing singularly unattractive expanses of olive-drab GI long Johns. #KoreanWar

Jan 19, 1951 #KoreanWar NYT Asked directly if he thought the atomic bomb should be used, General O'Donnell replied: “I personally believe we should have cracked them and cracked them hard as soon as it was determined it was the Chinese Communist army attacking us from across the border."

Mar 11, 1951 NYT After six months of sweeping up and down the scorched, shell-pocked Korean peninsula, the opposing Communist and United Nations forces grapple in a war of thrust and parry. Across a battlefield made miserable by the last snows of winter and the mud and floods of approaching spring, the UN forces struggle to wear down the enemy's superiority in manpower. In primitive Korea air war leads to such strange incidents as rocket attacks on camel caravans, ox carts and dugout canoes.
