Collections : [University of Michigan Bentley Historical Library]

The Franklin H. Bailey collection contains correspondence, diaries, a scrapbook, photographs, and other materials (including military discharge papers, Civil War songbooks, and scientific papers). 56 letters written to his parents in Adrian, Michigan from 1861-1865 detail his time in the military, with references to camp life, religion, sickness, concern over money matters, and skirmishes in which he was engaged, including a graphic account of the battle of Pittsburg Landing. An additional undated Civil War letter from Minerva Bailey's first husband, Levi Greenfield, reports on rumors of victories at Richmond and Vicksburg. Later correspondence includes letters he wrote to his wife while on a trip abroad in 1873 and a scrapbook of letters, 1880-1901, primarily concerning educational matters. Diaries (1865-1883) at least partially written in Pitman shorthand provide additional information on his war service, student life at Hillsdale College, finances, and teaching and scientific interests. A poem titled "Big Yank" refers to the Peninsula Campaign in 1862.
