Fact

Slavery was flourishing in 1860, not dying out. The property value of enslaved people ($3 billion) exceeded the value of all US industry and railroads combined ($2.5 billion). The war was not 'needless'—slavery would have lasted decades longer without it.

Gallagher rebuts the claim that the Civil War was unnecessary because slavery was on its way out. Using 1860 census data, he shows slave property was the single most valuable asset class in the US, and slavery was expanding, not contracting.

transcript

Gary Gallagher: There was a time in the literature when people argued that the war was needless, the Civil War was needless because slavery was on its way out. That's absolutely wrong. It was not on its way out. It was thriving. ... The 1860 census is our friend, and it tells us that the people who controlled the most wealth in the United States were slaveholders, and their property in slaves alone, not their other holdings, not their land holdings, just property in slaves were valued at about three billion dollars. The value of all industries, all railroads, all of that put together, fewer than two point five billion dollars.

Claim◆

Slavery was the sole cause of the Civil War—take it out of the picture and there is no war, period. But the motivation of the average Union soldier was not to end slavery; it was to salvage the Union, which they saw as a unique republic offering political voice and economic opportunity.

Gallagher sharply distinguishes causation (slavery) from motivation (Unionism). Without slavery, no war; but most white Northern soldiers enlisted to save the republic, not to free enslaved people.

transcript

Gary Gallagher: In terms of causation, if you take slavery out of the picture, there is no Civil War, period. That's not a long conversation you need. You ask the question. That's the answer. Let's go to the next question. The next question is, okay, so were most white people motivated to put on blue uniforms because they wanted to kill slavery? The answer to that is no, they were not. They were motivated to put on blue uniforms to salvage the Union, which they saw as a unique gift that the founding generation, based on the bloodshed in the American Revolution, had bequeathed the successive generations.

Claim◆

Individuals do matter in history. For the Union, Lincoln and Grant mattered beyond calculation. On the Confederate side, Lee extended the war long enough that emancipation became a Union war aim—in a perverse way, Lee furthered the cause of emancipation.

Gallagher rejects the 'great forces' view of history, arguing that Lincoln and Grant were indispensable for the Union, and that Lee's prolongation of the war inadvertently made emancipation possible.

transcript

Gary Gallagher: The great forces are all that matters and individuals don't really matter notion of history I think is ridiculous. Individuals really matter. For the United States, Lincoln and Grant matter beyond calculation—in this war. And on the Confederate side, if you take Lee out of the picture, the war doesn't last nearly as long as it does. In fact, we'll talk about this later probably, I think it could have ended early in the summer of 1862 with slavery still intact. I mean, in a perverse way, Lee furthers the cause of emancipation because he extends the war long enough that the United States says, 'We have to do this. We've gotta get rid of slavery to defeat the rebels.'

Mechanism

Lee's aggressiveness at Chancellorsville created an overconfidence—both in himself and his army—that directly caused the disastrous frontal assault at Gettysburg. Lee admitted he asked too much of his infantry. A straight line runs from May 3, 1863 to July 3, 1863.

Gallagher traces Lee's fatal overreach at Gettysburg back to the emotional high of Chancellorsville, where Lee's army spontaneously cheered him. This bonded Lee to his men in a way that made him believe they could do anything—a belief that shattered against the Union center on July 3.

transcript

Gary Gallagher: I think if you wanna understand Gettysburg, if you wanna understand Pickett's Charge, you need to look back to May 3rd at Chancellorsville, when Lee just decided that his infantry could do anything he wanted them to do. ... I think you can draw a straight line between May the 3rd at Chancellorsville when his infantry fought their way together and July the 3rd at Gettysburg. He admits it too as he writes letters to both his wife and Jefferson Davis saying, 'I asked too much of my infantry. No fault is on them. All the fault is on me.' And he was right. All the fault was on him.

Claim

Gettysburg is widely mislabeled the turning point of the war. The real military turning point was Sherman's capture of Atlanta in September 1864, which—combined with Sheridan's victories—re-elected Lincoln, kept emancipation on the table, and ensured the war would be pushed to unconditional Union victory.

Gallagher argues that while Gettysburg was a major Union victory, Lee's army escaped intact. Union morale hit its lowest point in summer 1864. It was Sherman taking Atlanta and Sheridan's Valley campaign that re-elected Lincoln, crushing the Confederacy's last real hope of a negotiated peace.

transcript

Gary Gallagher: So I think that United States civilian morale, the lowest point of the war for the United States is in July and August 1864. And if we'd been able to stick our microphones in people's faces and said, 'Well, but what about Gettysburg? That was the turning point of the war,' they would've said, 'What are you talking about?' ... Grant, against Lee would not reelect Lincoln. But other Grants, other things that Grant, part of his overall plan as general-in-chief, Sherman captured Atlanta in early September. And that just changed everything. That was a huge military turning point, and then on the heels of that, Philip Sheridan won a series of crushing victories in the Shenandoah Valley ... and it was Sherman, and to a lesser degree Sheridan, that reelected Lincoln, and not just Lincoln, but huge Republican majorities in both the House and the Senate in 1864.

Definition

The Lost Cause is the Confederate memory stream of the war: it denied slavery as the cause, claimed the war was about high constitutional principle and states' rights, asserted the Confederacy never could have won against overwhelming odds (making defeat honorable), and elevated Robert E. Lee above Jefferson Davis as its central icon.

Gallagher defines the Lost Cause as the Confederate version of memory: minimize slavery, emphasize states' rights, insist the fight was hopeless from the start, and make Lee the heroic symbol. He contrasts it with Union Cause, Emancipation Cause, and Reconciliation Cause memories.

transcript

Gary Gallagher: The Lost Cause is the Confederate memory stream of the war ... How do we make something palatable out of this catastrophic decision we made in 1861? ... First of all, it wasn't about slavery. Let's pretend it wasn't about slavery. It was about high constitutional principles. It was about states' rights ... And second, we never could have won. It was a hopeless fight against long odds, and so it was a gallant effort in pursuit of constitutional rights. ... And who are we gonna look to? ... Let's talk about Robert E. Lee. He won victories against the odds. So these are kind of the main tenets of the Lost Cause.
