Napoleon never debates; he seizes the infrastructure: the dogs (secret police, raised from Bluebell and Jessie's puppies), the food stores, the wall, the whiskey. The name itself, from the French revolutionary emperor, announces Orwell's thesis that revolutions crown their own kings. The show-trial confessions and executions mirror the Moscow Trials of 1936-38.
Napoleon is now the generic name for the revolution's gravedigger: the organizer who wins by controlling the levers while others win arguments. Quote the dogs at any meeting that applauds its own suppression of debate and everyone knows the reference.
The detail readers remember last: the coup began on day one, when Napoleon quietly took the puppies. Power's decisive move is always the one performed in private while everyone watches the debate. The eloquent fight for minds; the quiet collect teeth.
Why do the quiet ones, not the eloquent ones, end up owning the farm?
