In June 1863, Harrisburg braced for an invasion as the Confederate
troops of Lieutenant General Richard S. Ewell steadily moved toward the
Pennsylvania capital.
Capturing Carlisle en route, Ewell sent forth a brigade of cavalry under
Brigadier General Albert Gallatin Jenkins. After occupying Mechanicsburg
for two days, Jenkins's troops skirmished with Union militia near
Harrisburg. Jenkins then reported back to Ewell that Harrisburg was
vulnerable. Ewell, however, received orders from army commander Lee to
concentrate southward--toward Gettysburg--immediately. Left in front of
Harrisburg, Jenkins had to fight his way out at the Battle of Sporting
Hill. The following day, Jeb Stuart's Confederate cavalry made its way
to Carlisle and began the infamous shelling of its Union defenders and
civilian population. Running out of ammunition and finally making
contact with Lee, Stuart also retired south toward Gettysburg. Author
Cooper H. Wingert traces the Confederates to the gates of Harrisburg in
these northernmost actions of the Gettysburg Campaign.
