Lincoln writes to fellow veteran Eli C. Blankenship, who seeks information concerning David Rankin, who served under Lincoln in the Black Hawk War. Lincoln explains, "[Isaac Guliher] being an acquaintance of mine and belonging to the company in which Rankin wished to go wished to leave it and join mine . . . [I]t was agreed that they should exchange places and answer to each others names—as it was expected we all would be discharged in very few days. . . . The above embraces all the facts now in my recollection."Abraham Lincoln to Eli C. Blankenship, 10 August 1833, CW, 1:19; Ellen M. Whitney, ed., The Black Hawk War 1831-1832: Volume 1 Illinois Volunteers, Collections of the Illinois State Historical Library (Springfield: Illinois State Historical Library, 1970), 35:79, 96, 126, 176-178, 222, 224 .
