His Majesty was brought up on beer and so were his ancestors and his officers

It is disgusting to notice the increase in coffee used by my subjects and the amount of money that goes out of the country in consequence. Everybody is using coffee. His Majesty was brought up on beer and so were his ancestors and his officers. Many battles have been fought and won by soldiers nourished on beer, and the King does not believe that coffee-drinking soldiers can be depended on to endure hardship or beat his enemies in the case of the occurrence of another war.

I had witnessed the last parade in my lifetime in which German soldiers would goose step

Goose-stepping, grey-uniformed infantry, the unhappy heirs to the Prussian martial tradition, seemed keen to demonstrate their superiority over any other European infantry. I retreated to a café after half an hour to write in my diary: 'When the Wall comes down, as it must, the thoughts of all this Prussian military tradition married to West German economic power is extremely disturbing' (7 October 1989). Happily, I was wrong: after reunification the quietude of the West German military quickly infected the former East German military; I had witnessed the last parade in my lifetime in which German soldiers would goose step.

That does not sound much like Prussia

'Politics are the last thing we need. This at least I learned with the brethren at Neudietendorf. The state should be one family bound by love.'
'That does not sound much like Prussia,' said the Kreisamtmann.
