Not long thereafter, however, a series of rifts occur. Picasso, now wealthy from record sales figures, leaves the Bateau-Lavoir. Apollinaire moves into the heart of the Saint-Germain neighborhood. The poet Max Jacob, the poorest of them all, is one of the only bohemians to continue living in the hardscrabble misery of Montmartre. When the First World War breaks out, yesterday's friends part ways forever. Braque, Derain, and Vlaminck go to the front. Picasso stays in Paris. Apollinaire is wounded on the front lines in 1916.
