Putting aside the accuracy of Shaara's charge against Stuart (which I know has been debated on this board before), what are Shaara's sources for his depiction of Stuart as Gettysburg? Is it Marshall's memoir? What is the history of the debate and "memory" over Stuart's performance at Gettysburg: when did the charges against him start? Who started them? What is the consensus now? (Also, any other favorite anachronisms in KA?)
First and foremost: Shaara is a fiction writer.
Killer Angels and the movie
Gettysburg should not viewed as more historically accurate than Steve Berry's
The Lincoln Myth.
About those charges and who started them: After that Battle, there were not enough fingers for CS Generals to point to other GS Generals. All CS Corp Commanders and most Division Commanders had fingers pointed at them: Too early, too late, why fight there, why not fight there etc. R. E. Lee resigned of command after that battle (not accepted.) How those were propagated? Plenty of CS Generals in the battle who survived the war, published memoirs or talked to writers about their memories of the battle and wanted to get their tails out of blame. Lots of what ifs then. And Stuart was not around to defend himself, and Longstreet, the other common receiver of blame, just ignored them.
As to what happened, I agree 100% with Eric Wittenberg (
Plenty of Blame to Go Around is a great book, btw) :
Stuart was following orders to go to York. According to his memoirs, John Brown Gordon (of Early's Division of Ewell's Corps) had clear orders to cross the Susquehanna east of York (and he assumed that his next orders would be to go to Philly via Lancaster.) Ewell's Corps' main body, with Albert Jenkins in and out of PA as early as the 19th of June as the advance team, had orders to cross the river at Harrisburg. If you look at a map with different dates and the locations of the Confederate troops in PA, Gettysburg was not even in the equation, until both bridges were burned. Hill's and Longstreet's Corps were to congregate there and see whether they would go due east to York to cross there or Northeast to Carlisle & Harrisburg to cross there. Stuart's orders likely were: Go to York, if we are not there, go to Carlisle, because that's were we are crossing. No bridges, move back to West of Gettysburg to plan and regroup became the plan, which Stuart had no means to know, until he got up to Carlisle and after shelling the town got information that Ewell's Corps moved down South, and he followed. If there is a single person to blame about the result of Gettysburg for the CSA, is Robert Edward Lee who did not learn the lesson the Federals learned in Fredericksburg and decided to make a futile attack.
