Four carriers gone
Kido Butai's first team wrecked.
Carrier warfare's English-language proof-of-concept. Battleship admirals lost a debate the wrecks had settled.
US industrial confidence after June 1942 was a political fact.

Keep the cost as a range
about 3,000 Japanese and about 300+ US dead, usual published band Battle of Midway is not improved by a fake precise integer.
Memory is national
US/UK/AU/CA rites and the memory of Midway Atoll, central Pacific will not match. Name the difference when teaching Battle of Midway.
Unresolved
Census still a band
"about 3,000 Japanese and about 300+ US dead, usual published band" remains a band. New archives refine Battle of Midway; they do not un-happen 4-7 June 1942.
Archives uneven
Files on Battle of Midway remain unevenly open across Midway Atoll, central Pacific. Joseph Rochefort's paper trail is not the same as Chester W. Nimitz's.
Air group
The irreplaceable trained men Japan lost with the ships.
Teaching hours
English classroom hours on Battle of Midway still disagree with hours in Midway Atoll, central Pacific. Is this a guide to carrier combat? is often the gap.
Shifts
Japanese run
Dec 1941-May 1942: Pearl Harbor to Coral Sea.
The day
4 June 1942: Five minutes that English books never tire of.
Solomons
After June: A long war with a new balance.
Afterlife of the name
Battle of Midway left institutions and stories that outlasted 4-7 June 1942. Chester W. Nimitz became a caption; Midway Atoll, central Pacific kept the rubble or the letterhead.
Outlook
Scholarship
New archives will refine Battle of Midway (Torpedo squadrons, Yorktown sinks) without un-happening 4-7 June 1942.
Memory handover
As witnesses die, museums and film carry Battle of Midway. Chuichi Nagumo and Raymond A. Spruance will keep being recast.
This atlas
Battle of Midway stays a historical file -- a dated campaign, not a live order of battle or a method.
Risk
closed battle
Midway ended in June 1942. Residual risk is bad carrier analogy and film-as-log, not a pending Kido Butai.
Every later "carrier killer" headline still rents this day's prestige.
Tsushima 1905 remains the other Pacific decision-day in this atlas -- keep both.
