The Armies at Gettysburg > The Army of the Potomac > Cavalry Corps

Huey’s 2nd Brigade was guarding trains at Westminster and was not on the Gettysburg battlefield. However two units in the 1st Brigade were at the battle even though they did not belong to the Army of the Potomac. The Purnell Legion and a section of the 3rd Pennsylvania Heavy Artillery equipped and operating as light artillery had been guarding a river crossing in Maryland and had almost been snapped up by Stuart’s cavalry raid. They attached themselves to Gregg’s Division for safety as it went by and ended up at Gettysburg.
