Jan 18, 1950 #KoreanWar Russia extended her boycott of the Security Council to three more UN committees in protest the presence of Chinese Nationalists delegates. The view is that complete Russian withdrawal from UN would come only if the Western Powers took advantage of Russia's temporary absence.
To protest the exclusion of the Communist China, Russian representatives boycotted the UN from January to August 1950. The Russians  threatened the they would not feel bound by UN decisions taken in presence of representatives  the Government of Taiwan. The boycott led to the Russians not being able to veto the UN resolution which allowed an intervention of UN military forces in #KoreaWar.
Mar 20, 1950 TIME #KoreanWar For more than two months, the Soviet Union had boycotted all major UN proceedings because Communist China had not been admitted to membership. The US had agreed that it would abide by whatever the UN Assembly decided on the China issue. The Russian stand was just the opposite: it amounted to a demand that UN recognize whatever government the Russians recognized. https://time.com/archive/6796176/united-nations-poor-precedent/

June 5, 1950 TIME South of the 38th parallel Koreans are flexing their muscles in a new nationalism. During 40 years of Japanese rule, the life of a conquered people had led the Koreans into venality, stealth and the habits of petty crockery. The new Korean army’s best officers were once Japanese majors or lieutenants, and they still maintain Oriental protocol. All ranks are salute-happy, even sergeants rate the stiff-handed Japanese salute, and one battalion commander nostalgically keeps his old samurai sword hanging above his desk. https://time.com/archive/6614886/korea-progress-report-jun-5-1950/

Sep 11, 1950 #ColdWar TIME The North Koreans were finding it harder & harder to regroup for offensives and to bring up supplies.

Sep 14, 1950 Most British newspapers today express enthusiastic approval at General George Marshall's appointment as US Secretary of Defence. "The Times" says the appointment is "an event of great importance in both world and American affairs." No single man could command greater unity and respect in his own department, in the Administration as a whole.

* The appointment required a congressional waiver because the National Security Act of 1947 prohibited a uniformed military officer from serving in the post. This prohibition included Marshall since individuals promoted to General of the Army are not technically retired but remain officially on active duty.

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.

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.

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

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
