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.
UN/ROK dead in the hundreds for Inchon-Seoul in usual published bands; KPA much higher in dead and captured. Seoul civilians add a third column -- 1950's capital had already been a battlefield in June.
Marine dead on the seawall are the US icon cost; they are not the Korean city's cost.
Bands
Dated span (15-19 September 1950 (landing and city; Seoul follows to 28 Sep))
Battle of Inchon is taught as 15-19 September 1950 (landing and city; Seoul follows to 28 Sep). 1950-08 and 1950-10-25+ are the usual poles.
Theatre (Inchon (Incheon) harbour and the approa.)
Inchon (Incheon) harbour and the approach to Seoul, Korea is the geography of the ledger -- cities, seas, plants, or ministries as the file requires.
Wolmi bombardment
1950-09-13: Naval/air prep of the island.
Seoul ceremony
1950-09-28: Rhee and MacArthur in the damaged city.
Regions
Inchon (Incheon) harbour and the approach to Seoul
Core theatre of Battle of Inchon (15-19 September 1950 (landing and city; Seoul follows to 28 Sep)). MacArthur's 45-minute argument with JCS visitors -- a famous staff scene.
Argument
Aug 1950: Pusan plus a map of Inchon.
Seoul
16-28 Sep: Capital recapture.
Memory
After: USMC liturgy; Seoul museum; the Yalu shadow.
US / UK / AU / CA classrooms
US Marine liturgy and staff-college Chromite sit beside a thinner civilian textbook hour; UK/AU/CA UN veterans remember the turn out of Pusan more than the seawall.
Korean comparative reader
Seoul's War Memorial treats Chromite as a capital story: 15-28 September 1950, a city recaptured, not only a MacArthur still.

Douglas MacArthur (UNC) is a named maker of the Battle of Inchon story. Forced Chromite through, then overreached north. Relieved 11 April 1951 for a later argument.
Arthur Dewey Struble
Arthur Dewey Struble (Joint Task Force 7) is a named maker of the Battle of Inchon story. The naval joint commander of the landing -- under-photographed.
James H. Doyle
James H. Doyle (Amphibious group) is a named maker of the Battle of Inchon story. The tide-table admiral of the Marine story.
Edward Almond
Edward Almond (X Corps) is a named maker of the Battle of Inchon story. MacArthur's chief of staff given a corps -- a controversial soldier in Marine memory.
Oliver P. Smith
Oliver P. Smith (1st Marine Division) is a named maker of the Battle of Inchon story. The careful Marine who fought Almond's tempo -- later the Chosin commander.
Paik Sun-yup
Paik Sun-yup (ROK) is a named maker of the Battle of Inchon story. Already a major ROK face of 1950; the recapture of Seoul is a Korean officers' story too.
A recaptured capital is still a wrecked capital.
The KPA's southern collapse left graves and prisoners on the roads north.
