Collection contains correspondence and reminiscences of veterans of the Mississippi River Ram Fleet and the Mississippi Marine Brigade to Warren D. Crandall, and also material gathered by Crandall for his book, History of the Ram Fleet and Mississippi Marine Brigade, published in 1907. The bulk of the correspondence contains responses from veterans of the Mississippi Marine Brigade to invitations from Crandall to attend reunions of the brigade. Occasionally the correspondence contains reminiscences or other accounts of war service; these instances are noted in this inventory. The collection also contains biographical sketch forms filled out by veterans.
