Bingo!
Victor Davis Hanson’s Carnage And Culture covers that fairly well.
There was a great book by one of the Conquistadors themselves about the war-Bernal Diaz Del Castillo-called “The Conquest of New Spain”. Phenomenal read by one of the guys in the trenches. True story-he was retired in present day Guatemala living the life when a ship came in from Spain. He saw a book about the conquest by someone who wasn’t there. He became furious because it was wholly inaccurate so he spent several years penning the book to set it straight. He apologizes in the forward to the audience for being an uneducated grunt and then proceeds to write a great book.
