The Battle of Vicksburg began on May 18, 1863 and culminated with Vicksburg surrendering on July 4. Ulysses S. Grant's military campaign was one of the major successes of the Civil War. In 1906, The Vicksburg Military Park dedicated a memorial to the service of Illinois volunteers who participated in that campaign.
The Lundberg Collection contains the book
Illinois at Vicksburg which was printed to commemorate the dedication of the Illinois State Memorial at Vicksburg.
Illinois at Vicksburg describes Grant's campaign in detail and the aftermath of the siege. The volume also contains information about each Illinois regiment that served at Vicksburg. Each entry includes the regiment's history, its role in the battle and a roster of soldiers.
It's an interesting resource for anyone with Illinois ancestors who fought in the Civil War!
