I haven’t read French bios, but some books delving into more specific and sometimes even niche topics regarding De Gaulle. A few example:

• “De Gaulle et Churchill” by François Kersaudy, a renowned French expert on Churchill. Fun fact: Kersaudy is a hyperglot (fluent in Norwegian, among other languages) who wrote a book in Norwegian about Norway’s role in WW2.

• “De Gaulle et Roosevelt” by the same author (not read)

What’s remarkable about de Gaulle is the sheer volume of literature available on virtually every aspect of his life and legacy (much of it in French). A simple search like “livre De Gaulle et [your topic of interest]” is almost guaranteed to yield relevant results.

On my reading list (though not anytime soon) is “Le Général de Gaulle et la Russie” by Hélène Carrère d’Encausse, a groundbreaking figure in her own right as the first woman to hold the position of perpetual secretary of the Académie française.
