Still making my way through Allen Guelzo’s Gettysburg: The Last Invasion. Here is how Guelzo sums up Confederate assaults on July 2 led by James Longstreet and Jubal Early.
So much of the fighting ended in agonizingly near misses for the Army of Northern Virginia–the within-an-inch failure to capture Little Round Top…the last-minute blunting of Barksdale and Wilcox by George Willard’s “Cowards” and the charge of the 1st Minnesota…Ambrose Wright’s bitter moment of abandonment, just shy of Cemetery Ridge..Harry Hays’ Tigers having victory (not to mention captured Federal artillery) snatched from their hands by Samuel Carroll’s helter-skelter counterattack by the Evergreen Cemetery gatehouse and left without support by Rodes’ intertia…and finally the failure to overrun just one Union brigade on Culp’s Hill–that it has become almost a matter of habit to speak of Longstreet’s attack or Early’s assault on east Cemetery Hill purely in the mordant tones of failure. This is not really true. In the first place, although James Longstreet’s corps failed to turn Dan Sickles’ collapse into a complete rout, this was no more of a failure than Stonewall Jackson’s famous flank attack at Chancellorsville on May 2nd. Jackson, like Longstreet, achieved a great initial success; but Jackson’s attack also like Longstreet’s, fell far short of dislodging the entire Federal army (that work had to be completed by Lee on May 3rd). Jackson, like Longstreet, had begun his attack so late that darkness forced him to halt substantially short of their goal. Yet no one has ever suggested that Jackson’s descent on the Union right flank at Chancellorsville was a failure–or at least not in the way Longstreet’s descent on the Union left at Gettysburg would be described. (p. 351)
First, do you agree with Guelzo’s comparison of Longstreet’s assault with that of Jackson’s at Chancellorsville? To the extent that you do agree, does this make it more difficult to talk in counterfactual terms about what Jackson would have done had he been at Gettysburg? In other words, if Longstreet did everything that Jackson accomplished at Chancellorsville than why do we need to imagine his presence at Gettysburg?
