Old Abe was captured in 1861 by Chief Sky near the Chippewa River, near the town of Jim Falls, in Chippewa County, Wisconsin. She was subsequently traded to local farmer, Daniel McCann, for a bushel of corn, who in turn sold her to the 8th Wisconsin's Company C for $2.50.
Company C named the eagle after President Abraham Lincoln, and designed a special perch on which they carried the bird into battle. Old Abe participated in the Second Battle of Corinth (in which the 8th Wisconsin lost half of its men) and the Siege of Vicksburg, among other battles. In battle, Old Abe quickly became legendary, screaming and spreading her wings at the enemy. Confederate troops called her the "Yankee Buzzard" and made several attempts to capture her but never succeeded. Several times she lost feathers to bullets and saw her handlers get shot out from under her. When passing by, Generals Ulysses S. Grant, William T. Sherman, and William Rosecrans were known to doff their hats to the eagle.
In 1864, Old Abe returned to Wisconsin with several veterans who did not reenlist. Nevertheless, she remained famous and was invited to, among other events, the 1880 Grand Army of the Republic National Convention, and the 1876 Centennial Exposition in Philadelphia, Pennsylvania. When not at public events, her caretaker kept her in the Wisconsin State Capitol.
