The Fight at Monterey Pass (or Gap) was an American Civil War military engagement beginning the evening of July 4, 1863, during the Retreat from Gettysburg. A Confederate wagon train of Lt. Gen. Richard S. Ewell's Second Corps, Army of Northern Virginia, withdrew after the Battle of Gettysburg, and Union cavalry under Brig. Gen. H. Judson Kilpatrick attacked the retreating Confederate column. After a lengthy delay in which a small detachment of Maryland cavalrymen delayed Kilpatrick's division, the Union cavalrymen captured numerous Confederate prisoners and destroyed hundreds of wagons.
