With the war not going to well for the UN, General Douglas MacArthur planed a daring amphibious attack on the peninsula's west coast at Inchon. At first everyone was skeptical about MacArthurʻs idea, this was because Inchonʻs Harbor consist of a narrow approach channel, strong current, and wildly fluctuating tides. On top of all of this the harbor was surrounded by easily defended seawalls. But after much needed convincing on why the North Korean forces would not anticipate an attack on the Harbor he finally won over Washingtonʻs approval. Upon the confirmation of the invasion of Inchon Harbor General MacArthur planed very cautiously. This is because Inchon was thought to be one of the worst, if not the worst, places to have a naval attack due to tide conditions. So MacArthur launched Operation Trudy Jackson, two weeks before the actual invasion. Operation Trudy Jackson was run by Navy Lieutenant Eugene Clark, the Operation took place on a island off shore of Inchon. The objective of the Operation was to gather tide and current information, because if the tide and current were not right, there would be no way that the cruiser ships could even get close to shore.
On September 10, 1950 the preliminary bombardment began. For two days Marine air crafts did work on Wolmido with napalm, Wolmido is . The air crafts worked until the island looked as if it were a burnt husk. On the morning of the 13th two American cruisers and two Royal Navy cruisers anchored offshore and began firing upon the island. On the 14th the Navy did the same thing, but this time there it was a much more silent fight. The next morning, September 15, 1950 the main event took place, under another intense naval bombardment, the 3rd Battalion of the 5th Marines were sent ashore at 6:30. With little resistance, due to the three successful days prior, the island was under marine control within forty-five minutes. After such a tremendous start, the Marines had a day-long wait on their island for the next round. However the invasion was far from over, later in the afternoon the marines hit Red and Blue Beaches, withing an hour and a half they had secured Cemetery Hill over looking Read Beach. By the next morning the two beaches were linked up, and that very same day the Marines quickly advanced inland, so that by the end of the day the city and beachhead area were in the UNʻs control.
