Check out any Erik Larson book. For this specific topic, try his latest book called The Splendid and The Vile. It’s about Churchill; I think it’s what you’re looking for.

I know this sub is more about punchlines than literacy, but I'm reading Erik Larsen's The Splendid and the Vile right now, about Churchill's herculean effort to keep the UK going and trying to get help from the USA.
Highly recommended!!
