From that point, Melville focused his creative powers on poetry. Battle-Pieces and Aspects of the War (1866) was his poetic reflection on the moral questions of the American Civil War. In 1867, his eldest child Malcolm died at home from a self-inflicted gunshot. Melville's metaphysical epic Clarel: A Poem and Pilgrimage in the Holy Land was published in 1876. In 1886, his other son Stanwix died of apparent tuberculosis, and Melville retired. During his last years, he privately published two volumes of poetry, and left one volume unpublished. The novella Billy Budd was left unfinished at his death, but was published posthumously in 1924. Melville died from cardiovascular disease in 1891.
