The Chicago Tribune's front page for September 18, 1864, pulses with the energy of a nation in the throes of civil war and electoral fever. The lead story announces massive circulation for a Tribune compilation of the "Copperhead Convention" — a Democratic gathering in Chicago — selling 50,000 copies at two dollars per hundred, designed to expose what the paper calls "treasonable utterances" by peace Democrats like Vallandigham and Seymour. The paper urges loyal citizens to distribute it "everywhere, especially among Our Boys in the Army." Meanwhile, the war itself dominates: General Grant's Petersburg campaign continues with "terrific fire of shot and shell," while A.J. Smith's forces advance to Sulphur Springs south of St. Louis. A cavalry raid captured 2,500 head of cattle from Grant's army, though Union forces recaptured them and "some of the marauders also." Gold fluctuates wildly between 221-223. Illinois's draft quota has been reduced by 50 percent, but Secretary Stanton declares no further postponement is possible. The political scene brightens with Union meetings at Terre Haute and Valparaiso showing Lincoln's strength, while ex-Secretary Chase tours Ohio declaring Lincoln's certain victory.

September 1864 was the pivotal moment of the Civil War and American democracy itself. Lincoln faced an existential political threat: the Democratic Party, split between War Democrats and Peace Democrats ("Copperheads"), was nominating General George McClellan on a platform calling for immediate peace negotiations—effectively a surrender platform. The Tribune's ferocious focus on exposing "treasonable utterances" reflects deep anxiety that the North might vote away its military advantage. Meanwhile, Sherman's capture of Atlanta just weeks earlier had shifted momentum decisively. The election in November would determine whether Lincoln could continue prosecuting the war to total Union victory, or whether America would accept a Confederate peace. The Tribune's obsession with circulating anti-Copperhead material and celebrating pro-Union military news shows how completely the newspaper understood the stakes: the election would be decided by public opinion shaped by the press.

• The Tribune is selling a 50,000-copy compilation of Democratic convention speeches for two dollars per hundred copies, explicitly urging distribution to soldiers in the field. This was political warfare conducted through the printing press—the Union Army's postal system becoming a distribution network for anti-Democratic propaganda.
• Ex-State Senator McVey of Ohio was instantly killed on Friday "by the overturning of a stage," yet his son riding beside him "had both his legs broken." No mention of how McVey's death would affect Ohio politics, suggesting the Tribune didn't yet know its significance—a reminder that newspapers reported on the chaos of events before their larger meaning became clear.
• The paper reports that Northern refugees fled to Southern posts like Hilton Head and Beaufort to escape the draft—only to discover that General Foster ordered "all the able-bodied civilians" drafted anyway. Draft resistance was so serious that people risked occupying Confederate territory.
• The 38th Indiana Veteran regiment voted 353 to 5 for Lincoln's reelection as governor, while voting 823 to 10 for Lincoln himself. The 8th Indiana voted "unanimously" for both. These lopsided military votes were crucial: soldiers' ballots would become a deciding factor in November's election.
• Professor Goldwyn of Oxford University is touring the United States as a guest, having been a steadfast advocate for the Union cause in England. The Tribune uses his visit to pay tribute to British allies like John Bright, framing the Civil War as a struggle watched and supported by liberal democracy worldwide.

• General Meade's speech presenting the first-ever Medal of Honor awards happened on this very day—September 18, 1864—making this the first official presentation of what would become America's highest military decoration. Three enlisted men received medals for capturing Confederate battle flags: sergeants and privates from Delaware, Massachusetts, and Pennsylvania regiments. Meade's speech explicitly invokes ancient Greece, Rome, and biblical precedent to justify honoring common soldiers, a democratic impulse that still defines the Medal of Honor today.
• The Tribune mentions that General McClellan's resignation as a Major General had been 'forwarded by the Baltimore Delaware Canal' but delayed by 'an obstruction in the locks'—a darkly comic detail about how bureaucratic mishaps could delay military news. McClellan was the Democratic Party's presidential nominee against Lincoln just weeks away from the November election, so every rumor about his status mattered intensely.
• The paper reports that cotton plantations in the South, once thought to make the Confederacy invincible ('Cotton is King'), are now worthless because the blockade prevents export and the Confederate Army has no use for bales. This economic collapse of the Southern war economy happened in real time and was visible to contemporary observers.
• Ex-Secretary Salmon Chase is touring the Midwest declaring his confidence in Lincoln's reelection, despite having run against Lincoln for the Republican nomination just months earlier. Political wounds healed remarkably fast when facing Confederate defeat.
• The Tribune is offering mail delivery of campaign materials through Registered Letters at their office on Clark Street, and notes that remittances for bulk orders should 'be sent at our risk'—the newspaper essentially became a political direct-mail operation, monetizing the Copperhead backlash.
