Summary: a fine account of a key turning point of the American Civil War
At the beginning of July 1863 Robert E Lee, commander of the Army of Northern Virginia, invaded Pennsylvania. Lee reckoned that victory in the North, and the final defeat of the Army of the Potomac, would guarantee Confederate success in the war.
He picked his moment well. The Army of the Potomac was in disarray having suffered a major defeat at Chancellorsville in April. This brought about the replacement of that army’s latest commander, Joe Hooker, with the uninspiring George Meade. In addition after years of bloody conflict the people of the North were sick of fighting and Lincoln looked set to lose the 1864 election to a Democrat who would certainly sue for peace.
Lee’s plan was to concentrate his forces close to the town of Gettysburg and then defeat the Army of the Potomac in element as it moved up to intercept him. This would then have opened the road to Philadelphia and even the possibility of capturing Washington DC.
However Lee’s plan was thwarted by one of Meade’s subordinate generals, John Reynolds. Reynolds’ cavalry located Lee and alerted him to bring the rest of his Corps up to Gettysburg to disrupt the Confederate’s concentration.
So began three days of desperate and murderous fighting. One of the first casualties was John Reynolds, killed leading his troops into position. But the Union held the high ground at the end of the first day in spite of Lee’s best efforts. By the end of the day Meade arrived on the field, not exactly gruntled that he was being effectively forced by his subordinates to fight at a place not of his choosing .
Meade’s caution was understandable as the second day of the battle saw the Union almost losing the fight on multiple occasions. Famously Joshua Chamberlain held the extreme flank of the Union lines with an imaginative bayonet charge at a critical moment. But, as Guelzo points out, the fame of Chamberlain’s charge was principally the result of the fact that of the commanders on that flank of the army, he was the only one to survive. Paddy O’Rourke who commanded a New York regiment there, and their brigade commander, Strong Vincent, both made decisive interventions in the fighting but were killed and so did not live to tell the world their stories.
But the “sublime” moment of the battle, as far as Guelzo is concerned, occurred later on the second day when on the orders of another of Meade’s senior subordinates, Winfield Scott Hancock, the 1st Minnesota Regiment under Colonel William Colvill counter-attacked a Confederate assault that was all but assured to overrun the Union positions. Though the Minnesota troops were outnumbered 10 to 1 the impetus of their charge drove back the attackers and saved the day, and with that the Union.
The Union effort over the three days of Gettysburg was a fragmented affair, little coordinated by Meade. Instead the victory was much more a result of the initiative and courage of subordinate commanders and their troops responding selflessly to the crises that they encountered across the field. Guelzo argues that these soldiers knew that the future of the Union would be determined at Gettysburg and proved themselves ready to pay “the last full measure of devotion”, as Lincoln put it, if that was what was required. Eight score years later, it is difficult to reflect on any account of this battle with anything other than horrified awe.
