Ulric Dahlgren

Ulric Dahlgren (April 3, 1842 – March 2, 1864) served as a Union Army colonel. He was in command of an unsuccessful 1864 raid on the Confederate capital of Richmond, Virginia, and was killed in the raid. The major consequence of the failed raid was the Dahlgren Affair after incriminating documents were discovered on Dahlgren's corpse.

Early life
Dahlgren was born April 3, 1842, to Rear Admiral John A. Dahlgren and Madeleine (Mary) Vinton.

American Civil War
Papers found on the body of Dahlgren shortly after his death contained orders for an assassination plot against Confederate President Jefferson Davis. The discovery and publication of the Dahlgren Papers sparked controversy, and may have contributed to John Wilkes Booth's decision to assassinate U.S. President Abraham Lincoln a year later.
