Ariovistus Pardee Jr. (October 28, 1839 – March 16, 1901) was an officer in the Union Army during the American Civil War.

He rose to fame during the Battle of Gettysburg, where he led the defense of a portion of Culp's Hill on July 3, 1863.

)[4] Pardee served under Geary in the Shenandoah Valley, when MG Nathaniel Banks was bested by Stonewall Jackson.

Pardee criticized Geary's actions in that campaign, especially his abandoning Thoroughfare Gap in the face of a Confederate advance.

[7] At the rank of major, Pardee led the regiment at the Battle of Antietam on September 17, 1862, serving in the brigade of Lt. Col. Hector Tyndale in Second Division of the XII Corps.

[8] BG George S. Greene, the division commander, commended Pardee for his conduct at Antietam.

[10] The 147th Pennsylvania faced that field during the fighting on July 3, as XII Corps tried to win back ground lost to the Confederate troops of Lt. Gen. Richard S. Ewell on the day before.

(Geary was ordered away by Gen Meade with two brigades on July 2, to assist in the battle on the left flank.

Instead of going to reinforce the army's endangered left as intended, Geary mistakenly took Candy's command and Thomas L. Kane's brigade out of the battle for the rest of the day.)

The report of Col Charles Candy that Pardee's regiment advanced to the wall on the opposite side of the contested field is not supported by other accounts by credible witnesses.

The 147th suffered heavy losses, and Pardee complained that his right flank was thrown into disorder by routed troops.

Pardee received promotion to the brevet rank of brigadier general on January 12, 1865, for the Battle of Peachtree Creek.

[3] Colonel Pardee's health seems to have been undermined by war service, which would explain his passive role.
