The front page explodes with triumph: "FREEDOM TRIUMPHANT" declares the massive headline as the Constitutional Amendment abolishing slavery passes Congress. The New-York Tribune calls it "The Grandest Act Since the Declaration of Independence." The dramatic scene unfolds in real-time from Washington — anxious crowds pack the galleries, "confidence rising almost to exultation on the Union side, while a sullen gloom settles over the pro-Slavery benches." Key Democrats like Archibald McAllister of Pennsylvania's 18th District publicly justify their vote changes, casting ballots "against the corner-stone of the Rebellion." When the final tally comes at 1:30 PM, the House erupts: "Representatives and Auditors on the floor, soldiers and spectators in the gallery, Senators and Supreme Court Judges, women and pages, gave way to the excitement of the most august and important event in American Legislation." Three batteries of artillery immediately fire a hundred-gun salute in the heart of the city. The paper provides the complete roll call — 119 votes for, showing exactly which representatives from which districts made history.

This is the 13th Amendment passing the House of Representatives — the final legislative step before ratification by the states. After years of civil war that had already claimed hundreds of thousands of lives, Congress was finally ending slavery through constitutional amendment rather than just wartime measures. The Tribune mentions rumors of Confederate peace commissioners Stevens, Hunter and Campbell heading to Washington, reflecting the war's final phase. This moment represents the legal death of an institution that had shaped American politics and economics for nearly 250 years, setting the stage for Reconstruction and the fundamental transformation of American society.

• The paper notes that William H. Miller of Pennsylvania's 14th District, who 'was beaten at the last election by Geo. F. Miller, Union,' still voted pro-slavery and insisted on 'keeping his party foot on the nigrers' — a lame-duck congressman's final racist stand
• Amid the historic vote, rumors swirled that three Confederate Peace Commissioners were 'at City Point last night,' but 'most people say gold gamblers' new[s]' — suggesting financial speculators were spreading false peace rumors to manipulate markets
• The paper includes a grim partial list titled 'THE DEAD AT SALISBURY' showing Union prisoners who died at the rebel prison in North Carolina, including 'L. Applegate, Co.B, 112th Pa. shot by guard, Nov. 26, 1864' — a sobering reminder of ongoing wartime horrors
• James Ashley of Toledo, Ohio gets special credit as one of two Republicans who 'held the laboring oar' in securing passage, working 'night and day' for 'an entire month' to secure the necessary votes

• The paper mentions James Ashley of Toledo, Ohio as a key figure securing votes — he would later become so obsessed with impeaching Andrew Johnson that colleagues called him monomaniacal on the subject
• Alexander H. Coffroth of Pennsylvania's 16th District is praised for his vote change — but he was actually a lame duck who had lost re-election, making his flip less politically risky than it appeared
• The Tribune calls this vote more important than anything since the Declaration of Independence — and they weren't wrong: the 13th Amendment remains one of only 27 constitutional amendments ever ratified, out of over 11,000 proposed throughout U.S. history
• Those hundred cannons firing in celebration? Artillery salutes were so common in Civil War-era Washington that residents complained about windows breaking from the concussions — the capital was basically under constant celebratory bombardment
