[...] Steinbeck turned out 120,000 words in five months, beginning early in September 1934, only weeks after the notorious Bloody Thursday (mentioned several times in the text), July 5, 1934, when San Francisco police made international headlines by shooting two people and wounding many others in an effort to break up a longshoremen’s strike. The eyes of the world were on the turbulent scene in California for another reason: social-protest novelist Upton Sinclair was conducting a strident campaign for the state’s governorship based on his EPIC (End Poverty in California) share-the-wealth plan.

When In Dubious Battle was published in 1936, Steinbeck was surprised that this novel, which he had thought most readers would find objectionably grim and controversial, reached the best-seller lists. It also received surprisingly few hostile reviews from critics on either the political right or left. The most conspicuous exception to this favorable consensus was Mary McCarthy’s denunciation of the novel as “academic, wooden, inert” and of Steinbeck as “certainly no philosopher, sociologist, or strike technician.” She was then a recent Vassar graduate writing for The Nation and would not publish the first of her own chicly cynical satires until 1942; but her attitude started a feud that lasted the rest of Steinbeck’s life.
