In April, Orwell returned to Barcelona. Wanting to be sent to the Madrid front, which meant he "must join the International Column", he approached a Communist friend attached to the Spanish Medical Aid and explained his case. "Although he did not think much of the Communists, Orwell was still ready to treat them as friends and allies. That would soon change." This was the time of the Barcelona May Days and Orwell was caught up in the factional fighting. He spent much of the time on a roof, with a stack of novels, but encountered Jon Kimche from his Hampstead days during the stay. The subsequent campaign of lies and distortion carried out by the Communist press, in which the POUM was accused of collaborating with the fascists, had a dramatic effect on Orwell. Instead of joining the International Brigades as he had intended, he decided to return to the Aragon Front. Once the May fighting was over, he was approached by a Communist friend who asked if he still intended transferring to the International Brigades. Orwell expressed surprise that they should still want him, because according to the Communist press he was a fascist. "No one who was in Barcelona then, or for months later, will forget the horrible atmosphere produced by fear, suspicion, hatred, censored newspapers, crammed jails, enormous food queues and prowling gangs of armed men."
