Why did Orwell come to Spain and join the POUM militia rather than the PSUC? What were his experiences like at the front? How had Barcelona changed between when he first arrived and when he went there on leave? Why did violence break out between the POUM aligned with the Anarchists and the PSUC allied with the Central Government? Returning after his second tour of duty at the front, why did Orwell fear arrest and possible execution? What does Orwell believe the fascists were able to win the Civil War?
