Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many died?
UN/ROK killed in the Inchon-Seoul operation are usually given in the hundreds. KPA dead and captured were much higher. Civilian deaths in Seoul's recapture are part of a wider 1950 urban ledger -- use ranges, not a fake precision.
Why did it work?
Surprise, naval/air preparation, KPA overstretch in the south, and a plan fitted to tides. It was not magic and not costless.
Why was the Navy sceptical?
Tides, mudflats, channels, and seawalls -- Inchon was a hydrographic nightmare on paper. The sceptics were not cowards; they were sailors who could read a chart.
Did it end the Korean War?
No. It ended the first campaign. The war continued until 27 July 1953, after Chinese intervention.
Who commanded?
MacArthur at UNC; Admiral Doyle afloat; General Almond (X Corps); Marine generals (Smith and others) on the landing force; ROK units under the same operation.
Two pulses (island, city) then an inland capital fight. Teach the Han, not only the ladder over the wall.
Exploitation south-north was a political choice dressed as momentum.
Principles
Seoul's second 1950 liberation
A Korean capital fact.
A success that licensed overreach
The Yalu road.
Seawall
The urban waterfront obstacle that replaced a sandy beach. Read as a 15-19 September 1950 (landing and city; Seoul follows to 28 Sep) concept in Inchon (Incheon) harbour and the approach to Seoul, Korea.
Yellow Sea tides
Extreme range that set a two-pulse plan. Not a present instruction.

Diagrams
From Pusan holds (1950-08) through Inchon secured (1950-09-16-19) to China enters (1950-10-25+) in Inchon (Incheon) harbour and the approach to Seoul, Korea. One sequence, not a staff overlay.
Douglas MacArthur (UNC) and Arthur Dewey Struble (Joint Task Force 7) sit at the centre of most English accounts; Syngman Rhee and Kim Il-sung correct the usual photograph.
Limits
Source limits
Figures such as "UN/ROK dead in the hundreds at Inchon-Seoul; KPA dead and captured much higher -- published bands vary" stay in ranges because records are incomplete, political, or still closed. How many died? is answered as a band.
No how-to
Battle of Inchon is described as history. This page does not teach weapons employment, coup method, or attack planning.
Memory bias
English-language fame of Battle of Inchon and local memory in Inchon (Incheon) harbour and the approach to Seoul, Korea are not the same map. Kim Il-sung is often the correction the first photograph drops.
Tide ranges are 1950 hydrography. They are not a current assault manual.
Urban Seoul fighting is described as cost, not as a street-fighting lesson.
