Orwell left Spain a very disillusioned man; he realized how much propaganda they’d been fed (told of great victories where there had been no batlle at all, and the complete cover-up of disastrous defeats); he’s lucky he got out alive. People like Orwell & Hemingway must have felt like fools as they aged; they’d certainly been played for fools.
Orwell I think did. Hemingway I’m not so sure.
