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?
About 620,000 was the long-standard military estimate; recent work (Hacker and others) suggests around 750,000, with a published band reaching about 850,000 when some civilian deaths are considered. Disease killed more than combat.
Was it about slavery?
Yes, as the cause of secession. Lincoln's initial public aim was union; emancipation became a war aim in 1862-63. Both facts are true and in sequence.
Why did the Union win?
Population, industry, rail, naval blockade, Black manpower, and -- in 1864-65 -- a coordinated strategy under Grant. Confederate advantages in interior lines and military culture were real and insufficient.
What was Gettysburg?
A three-day battle in Pennsylvania (1-3 July 1863) that ended Lee's second northern invasion. Combined with Vicksburg's fall on 4 July, it was the war's political-military hinge -- not the last fighting.
What did Reconstruction do?
It briefly empowered Black voters and Republican governments in the South, passed the 14th and 15th Amendments, and then collapsed under violence and northern fatigue after 1877.
The eastern war was a short brutal corridor between two capitals. The western war was a river-and-rail war that split the Confederacy.
Sherman's march is described as political economy in motion -- not as a guide to destroying civilian infrastructure.
Principles
Coordinate theatres
Grant's 1864 insight: press everywhere so Lee cannot feed on transfers.
Sea and river control
The Confederacy was a land power that needed exports.
Hard war vs conciliation
Sherman and Lincoln's 1865 terms -- two tools, one end-state.
Memory is a campaign
The Lost Cause shows losers can win the statues.
Steps
- Sectional break
1860 election and secession winter.
Ballots can be a fuse when a labour system is on the ballot.
- Improvised war
1861-62: volunteers, early defeats, naval blockade.
Neither side had a European-size staff.
- Emancipation turn
1862-63: Antietam, the Proclamation, USCT.
War aims can widen in a civil war.
- Twin hinges
July 1863: Gettysburg and Vicksburg.
Two theatres, one weekend of news.
- Attrition and election
1864: Grant, Sherman, Lincoln re-elected.
Atlanta was a ballot-box battle.
- Surrender and after
1865-77: Appomattox, assassination, Reconstruction.
The last campaign was legal and terroristic, not only military.
Diagrams
East (capitals) vs west (rivers) -- a simple split that explains Grant's rise.

Limits
Death-toll method
Census-based estimates vs muster rolls -- we keep a band.
Guerrilla undercount
Missouri and the Indian Territory are still being researched.
No how-to
Tactical narrative is historical description.
Gettysburg was decisive as a raid that failed, not as the last battle.
Guerrilla war in Missouri and the border was a third map English films often skip.
