Lee asks Davis to let him go; Davis refuses
Robert E. Lee's Army of Northern Virginia had just staggered back across the Potomac, beaten at Gettysburg after three days that cost more than 50,000 combined casualties. His invasion of the North, meant to force Union politicians toward peace, had failed. In a letter to Confederate President Jefferson Davis, Lee offered his resignation, saying he no longer trusted his own judgment. Davis refused it on receipt, leaving Lee in command.
Lee's letter, and Davis's flat refusal, show a Confederacy with no bench to turn to after its best general's worst defeat. Historians still cite the exchange as evidence of how little margin the Confederacy had left after Gettysburg.
QWho first called Gettysburg's ground the strongest defensive position he'd ever seen?
Major General Winfield S. Hancock said it to Major General Oliver O. Howard as Union forces settled onto the high ground south of town: "I think this the strongest position by nature upon which to fight a battle that I ever saw." Hancock had been sent ahead by Meade to assess whether the army should make its stand there, and his read on the terrain, the fishhook-shaped ridgeline anchored by Culp's Hill and Little Round Top, helped confirm Gettysburg as the place to fight rather than retreat further. The Union army held that ground for all three days of the battle. Hancock himself was wounded on the third day, shot through the groin during the repulse of Pickett's Charge, but stayed on the field directing his corps from a stretcher.
QWhat changed about who could fight for the Union after January 1, 1863?
The Emancipation Proclamation did more than declare freedom on paper. It opened the door for African Americans to enlist in the Union army, something federal policy had largely barred in the war's first two years. That single provision opened a new source of Union manpower at a moment when the North badly needed it. The proclamation's reach was broad: it applied to more than 3.5 million of the roughly 4 million enslaved people then living in the country, covering every person held in bondage within the rebelling states. Lincoln issued it as a wartime measure, tied explicitly to suppressing rebellion, but its practical effect was to convert emancipation into a Union recruiting tool almost overnight.
QWhat argument did President Buchanan make just before leaving office that the Union would later ignore by force?
James Buchanan, Lincoln's predecessor, argued in the secession winter of 1860-61 that Washington had no constitutional authority to stop states from leaving. His reasoning: "The power by force of arms to compel a State to remain in the Union was not among the 'enumerated powers granted to Congress.'" Buchanan believed secession was illegal but also believed he lacked any lawful tool to reverse it, so he did nothing to stop the Deep South states from walking out during his final months in office. Lincoln's administration rejected that logic entirely once war began at Fort Sumter, treating the Union as permanent and secession as rebellion to be crushed by exactly the armed force Buchanan had ruled out.
