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?
RAF Fighter Command aircrew dead in the battle period are usually given in the high hundreds (often cited around 500-1,000 depending on who is included). Luftwaffe aircrew losses were higher. Civilian Blitz deaths are a separate, larger urban ledger.
Did it stop an invasion?
It denied the daylight air superiority Sea Lion required. Whether Hitler would have launched even with that sky is a separate counterfactual. The battle made invasion implausible.
What was the Dowding system?
Radar reporting, filter rooms, and sector-controlled fighters -- an integrated air defence, historically described, not a modern C2 manual.
What was the Big Wing debate?
Whether to mass fighters (Leigh-Mallory) or intercept in smaller, earlier packets (Park). It became a personnel war that cost Dowding and Park their posts.
Who were the Few?
Churchill's name for Fighter Command pilots. The roster included many non-British airmen. Bomber and Coastal crews are often left out of the sentence.
Three phases in the English telling: Channel, airfields, London. German directives were messier. Teach the mess.
15 September is a ritual peak, not the only hard day.
Principles
Integrated air defence shown
Radar plus control rooms.
A civic vocabulary
The Few -- for better and narrower.
Big Wing
Leigh-Mallory / Bader massing concept -- a bitter intramural fight. Read as a 10 July-31 October 1940 (official RAF dates) concept in English Channel, southeast England, London approaches.
Adlertag
13 August 1940, "Eagle Day." Not a present instruction.

Diagrams
From France falls (1940-06) through London day raid (1940-09-07) to Film Battle of Britain (1969) in English Channel, southeast England, London approaches. One sequence, not a staff overlay.
Hugh Dowding (Fighter Command) and Keith Park (11 Group) sit at the centre of most English accounts; Witold Urbanowicz and Robert Watson-Watt correct the usual photograph.
Limits
Source limits
Figures such as "about 500-1,000 RAF aircrew dead in the battle period; Luftwaffe losses higher; civilian Blitz deaths are a linked but wider ledger" stay in ranges because records are incomplete, political, or still closed. How many died? is answered as a band.
No how-to
Battle of Britain is described as history. This page does not teach weapons employment, coup method, or attack planning.
Memory bias
English-language fame of Battle of Britain and local memory in English Channel, southeast England, London approaches are not the same map. Robert Watson-Watt is often the correction the first photograph drops.
Sector-station tactics are historical. They are not a current fighter-control guide.
The Big Wing argument is a personnel file as much as a tactics file.
