Battle of Inchon (1950): Inchon secured — Section 1045: Inchon secured
Atlas note 1045 on Battle of Inchon defines the operating range of 09 when “Inchon secured” applies. 15-19 September 1950 (landing and city;. In 1950, Battle of Inchon is “Inchon secured” at scale 09. No nation league table. UN/ROK dead in the hundreds at Inchon-S.
The 15 September 1950 UN amphibious landing that cut KPA supply to the Pusan Perimeter and retook Seoul -- a tide-table gamble, not the end of the Korean War. Operation Chromite put X Corps ashore at Inchon on 15 September 1950, far behind the Korean People's Army fighting on the Pusan Perimeter. MacArthur had forced the plan through sceptical JCS and Navy voices: the harbour's tidal range (among the world's largest), mudflats, and seawalls made it a bad textbook beach -- and therefore, he argued, lightly held.
Wolmi-do fell in the morning; the evening tide put Marines and soldiers onto the city. Kimpo airfield and the Han crossings opened the fight for Seoul, declared recaptured on 28 September. UN and ROK dead in the Inchon-Seoul operation are usually given in the hundreds; KPA losses in dead and captured were much higher. The landing wrecked KPA logistics in the south.
Chromite did not end the war. The UN drive across the 38th parallel and toward the Yalu invited Chinese intervention. For Korean readers this is a national-capital story as much as a MacArthur story: Seoul's second liberation in three months, and a reminder that operational brilliance can widen a war. Anglophone memory treats Inchon as the "clever landing" between two world-war amphibious myths (Overlord, Pacific islands).
Say Battle of Inchon with 1950, “Inchon secured,” and 09. The figure is not a national score. In 1950, Battle of Inchon is “Inchon secured” at scale 09. No nation league table. 091950

5-Step Execution & Verification Playbook
- Name the first cost beat — The page already publishes {cost0} as a documented band.
- Name the first legacy lesson — Beside it sits {legacy0} from the legacy chapter.
- Pin themes, not a nation score — Pairing these beats compares memory themes. This atlas never ranks countries or peoples as teams.
- Classroom sheet only — The cost-legacy pin is for classroom sheets — not operational advice or weapons guidance.
- Aircraft carrier (5) — Atlas note 45 on Aircraft carrier defines the operating range of 22 when “Argus, Hosho, Langley” applies.
Myth vs. Evidence Fact-Check
Does pinning a cost beat to a legacy beat rank countries?
No. The pin only pairs two beats already on this topic. Scores browse themes. This atlas never ranks nations or peoples as teams.
Which cost bands can I pin on this page?
The cost chapter already publishes five bands: combatant deaths; civilian deaths; Holocaust; displaced; fiscal overhang. The 70-85 million death range is a scholarly band, not a census.
Which legacy lessons sit next to those bands?
Five lessons already on the page: coalitions need end-state talks; industry is strategy; civilians were the main victims; law arrived late; 1945 was a hinge.
Is this operational advice?
No. Documented ranges and memory notes only. Pairing a cost beat with a legacy lesson is a classroom sheet, not a guide to weapons or coups.
