Lincoln writes and signs an affidavit attesting that Isaac Anderson, a member of Lincoln's volunteer company during the Black Hawk War, lost his own horse in the service of the United States. Anderson seeks compensation from the government for the lost horse, "valued . . . at fiftyfive dollars." Lincoln explains, "[the] said horse was turned out to graze in consequence of sufficient forage not being furnished by the United states, and was thereby lost . . . without any fault or negligence on the part of said Anderson. . . . The affiant makes the above statements from memory only, but feels confident they are substantially correct." Affidavit Concerning Isaac Anderson's Lost Horse, 29 June 1839, CW, 1:152.
