While stationed at Galveston during the war, Hobby married a widow, Mrs. Gertrude Menard. During the war he wrote several patriotic poems. These, including "The Sentinel's Dream of Home," were widely published in newspapers of the period. After the war, he devoted himself more seriously to literary work. His best-known prose was his "Life of David G. Burnet" (1871). "Serfs of Chattenay and Miscellaneous Poems" (ca. 1881) contained his "Poem in Honor of Colonel Thomas S. Lubbock." After the war Hobby disposed of his Refugio County holdings and settled at Galveston, where he resumed the mercantile business. He spent the last years of his life in Silver City, New Mexico.
