When I pressed the "give up" button and had a look, something told me that Philippe Leclerc de Hauteclocque would be the least guessed... I wasn't wrong...... Even writing his name is like some kind of spelling test
Nimitz, Yamamoto, etc. were admirals, who, like generals, are "flag officers." Maybe change the quiz title to "Who is that Flag Officer?" Just a suggestion, I liked the quiz.
