Orwell details noteworthy changes in the social and political atmosphere of Barcelona when he returns after three months at the front. He describes a lack of revolutionary atmosphere and the class division that he had thought would not reappear, i.e., with visible division between rich and poor and the return of servile language. Orwell had been determined to leave the POUM, and confesses here that he "would have liked to join the Anarchists," but instead sought a recommendation to join the International Column, so that he could go to the Madrid front. The latter half of this chapter is devoted to describing the conflict between the anarchist CNT and the socialist Unión General de Trabajadores (UGT) and the resulting cancellation of the May Day demonstration and the build-up to the street fighting of the Barcelona May Days. "It was the antagonism between those who wished the revolution to go forward and those who wished to check or prevent it—ultimately, between Anarchists and Communists."
