The Great War between Britain and its territories in Europe.
- Bartimaeus works for Czech magicians in the general uprising.
- He steals battle plans while dressed as an ambulance driver.
- Much of Europe is devastated: trenches are still visible in Prague ninety years later, while parts of London remain pockmarked by ‘wastelands’ created by bombardments by enemy djinn.
- Britain wins the war and retains control of Europe for the remainder of the century.
