The Confederate Approach on Harrisburg: the Gettysburg Campaign's Northernmost Reaches, by Cooper H Wingert

A passing knowledge of the events leading up to the civil war's most damaging battle for the Southern war of independence won't do here. General Lee's order to capture Harrisburg, given to newly appointed corps commander Richard E Ewell, was a major priority only if it proved demoralizing for the few Yankee defenders of the capital of Pennsylvania under General Darius Couch.
A detailed history of the first true excursion into the deepest regions of the north, this slim volume is an hourly approach to the whereabouts of this division here, that battalion there, and a multitude of brigades everywhere in Bridgeport, now Lemoyne, the lengths of the Carlisle Pike and Trindle Road, and the elevations of Slate and Sporting Hill, culminating in the Confederate advance into Carlisle and the razing of the barracks where the long lost cavalry of JEB Stuart finally shows up.
Of course, the immediate call for all hands to Gettysburg, thirty miles south, saved the day for Governor Curtin, rebellious General Couch, and wounded Lieutenant General James A Beaver, who 24 years later assumed the position as 20th governor of our commonwealth.
A valuable listing of minor players who played significant roles in the horror of our most superfluous war.
