This period came to an abrupt end when he was expelled from the University for failure to complete courses for an entire semester. Again, he found himself alone. Overnight his supposedly pacifist friends, members of "The Yanks Are Not Coming", became, following Germany's invasion of the Soviet Union, passionate supporters of the war. No longer at home in Berkeley, Moore moved to San Francisco, closer to the Rexroth circle and to a new and unexpected interest in modern dance. For several strenuous years Moore studied dance with May O'Donnell and José Limón. He continued to write poetry and became a counselor for young men seeking to apply for Conscientious Objector status.
