Gettysburg is quite frankly one of the biggest paradoxes of the Army of Northern Virginia in my opinion. Lee and his subordinates had that army working very well and they were in a groove, especially after Fredricksburg and Chancellorsville. In every battle you might expect one or two of the high command to have an off day, but for basically the entire high command to just cease to function rationally at Gettysburg for 3 days is incredible to me. You can even go back farther and say it goes back Jeb Stuart being ambushed at Brandy Station in early June that just threw the Army of Northern Virginia off its rocker. It really is one of those strange instances of the war.
This particular battle has been micro studied/analysed/researched and reflected upon by historians and military academics more than any other battle in history with perhaps the exception of Waterloo. It has also been refought multi-million times on war-gamers boards across the world but none of them have really narrowed it down to one particular reason for the Confederate failure during those three bloody days in the Pennsylvania sun-shine.
I too along with many other arm-chair generals have also studied/researched/walked the hallowed ground in an attempt to piece together of what went wrong. We have at our disposal many accounts from those who were actually there with their own particular version of events, but invariably they differ from each other's telling of the story. Lee died before he wrote his autobiography but I have no doubt that he too would have written just as confusing interpretations of events as most of his generals wrote after the war.
But we do have one unique moment when he bared his soul following the disaster of Pickett's charge-this happened in the early hours of July 4th when an exhausted Lee sat down with cavalry commander John Imboden and after extolling Pickett's troops as magnificent added......"And if they had been supported as they were to have been-but for some reason, not yet fully explained to me, were not-we would have held the position and the day would have been ours".
In many respects Lee's analysis immediately following the fighting on the third day and why it failed aptly describes the entire battle. My study of those three days have unearthed many tangible and direct reasons-in fact a whole catalogue of them-that I believe explain Lee's ultimate failure at Gettysburg. And when put together and transcribed onto the battlefield, one after another after another, any invading army commander would have to have been at the top of his game to successfully counteract those events to achieve an overall victory.
They are in no particular order of importance just merely chronological:
1. Buford's excellent evaluation of the high ground and the following sacrifice by the Federal I Corps in their valiant attempt to hold their lines on July 1st.
2. The failure of Ewell to timely inform General Lee on July 1 that Culp's Hill was vunerable and subject to capture.
3. The absence of JEB Stuart
4. Ewell's subsequent failure to pursue with his Second Corps later on July 1.
5. Powell Hill's complete mishandling of Third Corps
6. The failure of Second Corps senior officers to co-ordinate their commands into action on July 2.
7. The loss of John Bell Hood early in the fighting on July 2.
8. The breakdown of the July 2 echelon attack and the wounding of Dorsey Pender.
9. The collective decision by Meade and his corps commanders to stay and fight on July 3.
10. Lee's failure to assume direct tactical command on July 3.
11. Meade's localised counterattack at Culp's Hill early on July 3.
12. The magnificent performance of Winfield Hancock throughout the battle but especially on the third day.
13. Longstreet's disobedience on July 3.
14. The ANV high command completely under-estimating the resolve of the ordinary Union soldier when fighting to defend his home-turf.
I'm sure that you three can come up with some more-Lancer's comment of lack-of Jack-although I may agree with his supposition to include Jackson in the list would be a direct what if? I have concentrated a list of what was! Far better military academics than this Reb could write whole dissertations on any of the above-but in my opinion-which doesn't amount to a hill of beans-the above list of events during those three days stacked the cards against Lee let alone his apparent attacks of angina robbing him of his usual indefatigable stamina and military craftiness.
