You mentioned Richard Toye before, so I had a look at what appear to be his two main books on Churchill, and as far as I can see he devotes barely a page to the Bengal Famine, in his
Churchill’s Empire:

The “Nobel-prize winning analysis” referred to is I believe by Amartya Sen, and as indicated above, it has not gone unchallenged. You can read a lengthy response from the historian Mark B Tauger
here, and then a fairly tedious back and forth between Tauger and Amartya Sen in The New York Review
here and
here. I’m in no way qualified to judge who has the right of it, but based on that exchange I’m not really buying the idea that there is a consensus among scholars regarding the causes of the famine. Who are the other historians you have in mind?
