Two others I would recommend are Robert Ruark and Jim Corbett.
Corbett was a British gov't functionary in India during the Raj, and his duties included hunting man-eating tigers and leopards. Hair-raising, terrifying, oh-hell-no all fall short of describing his hunts. Easily the best of the best in adventure hunting.
Ruark is more of a commercial writer whose success allowed him to spend a lot of time in Kenya, and good writing ensued. His novel "Something of Value" is about Mau-Mau in Kenya in the 50's. It certainly shows the start of the descent of Africa from colonial civility to todays barbarism. If you are an older guy, who spent his childhood in the fields and woods, his "Old Man and the Boy" books are something you will reread often. Mostly a collection of his Field and Stream columns, I often think he was looking over my shoulder as I learned the outdoor crafts.
You can't go wrong with any of them, all are guys you'd love to hoist a brew or three with.
Thanks for the recommendations.
Yes I mean Peter Hathaway Capstick. Just looked at the note I made in Kindle which I relied on and it shows the book by: Capstick Peter Hathaway. I thought: ok Capstick might be the publisher. That is what modern technology will do for you.
