On November 19, 1935, the Second Red Army set out on its own Long March. He Long's force was driven further west than the First Red Army, all the way to Lijiang in Yunnan province, then across the Jade Dragon Snow Mountain massif and through the Tibetan highlands of western Sichuan. He Long and Xiao Ke were married to sisters who also accompanied the army. He Long's wife, Jian Xianren, carried the baby daughter she had given birth to three weeks before the retreat began. Jian Xianfo gave birth to a son in the desolate swamps of northern Sichuan. Forces of the Second Army detained two European missionaries, Rudolf Bosshardt and Arnolis Hayman, for 16 months. Bosshardt later related his account of the details of daily life on the Long March in a book.
