A Daily Track of the Civil War: Day 4 - The Virginia Convention Erupts & Lincoln Invokes Militia Act of 1795

Monday, April 15^th, 1861. Washington wakes to a nation transformed. The surrender of Fort Sumter has ended any lingering hope that the crisis might be contained, and President Lincoln moves swiftly to define the federal response. Early in the morning he issues the Proclamation Calling Forth the Militia, summoning 75,000 volunteers to suppress the rebellion and announcing that “combinations too powerful to be suppressed by the ordinary course of judicial proceedings” now threaten the Union. The proclamation electrifies the North and shatters the political balance in the Upper South.

The Virginia Convention met under a tension so sharp it seemed to vibrate in the air, and John Janney of Loudoun County, the dignified, Union‑leaning president of the assembly, found himself presiding over a chamber he could no longer steady. Lincoln’s call for 75,000 volunteers arrived like a thunderclap, and the delegates — many of whom had resisted secession for months — erupted into outrage, disbelief, and grim declarations that the crisis had crossed a fatal line. Janney, who had been chosen precisely because he was a calming, constitutional presence, sat visibly shaken as the political center of gravity lurched away from him. He tried to maintain order, tapping the gavel, calling for decorum, but the room surged with speeches insisting that Virginia could not, must not, furnish troops to coerce the Southern states. Moderates who had once stood with Janney now slipped from his grasp, pulled by the force of events toward the secessionist position. By the end of the day, the convention had not yet voted to leave the Union, but the pivot was unmistakable: under Janney’s own gavel, Virginia had begun its irreversible slide toward secession.

Maryland, Kentucky, and Missouri enter a period of intense political strain, their leaders pulled between loyalty to the Union and sympathy for the South. The national map is shifting by the hour, and Lincoln’s decision — necessary, decisive, and irreversible — becomes the hinge on which the next phase of the conflict turns.

THE NATION AROUSED — LINCOLN CALLS FOR TROOPS.

Lincoln’s proclamation forces immediate legal questions to the surface. By invoking the Militia Act of 1795, he asserts the executive’s authority to call out state militias without waiting for Congress to convene. His language frames the Confederacy not as a foreign nation but as an unlawful insurrection — a distinction that will shape every legal argument of the coming months.

In Richmond and Montgomery, Confederate leaders seize on the proclamation as legal confirmation of their worst fears. To them, Lincoln’s call for troops is an act of coercion against sovereign states, justifying their withdrawal from the Union. Southern newspapers argue that the Confederacy now stands on firm legal ground as a nation defending itself from invasion. Two competing constitutional visions — one Unionist, one secessionist — harden into place.

LINCOLN’S PROCLAMATION — SEVENTY-FIVE THOUSAND MEN CALLED OUT.

The military landscape changes dramatically today. Lincoln’s call for 75,000 volunteers triggers an immediate mobilization across the North. State governors begin organizing regiments, reopening armories, and preparing transportation routes to Washington. Telegraph lines crackle with orders, offers, and urgent requests for supplies. The U.S. Army, small and scattered, suddenly becomes the nucleus of a massive citizen force.

In the South, the mood is triumphant but tense. The victory at Sumter has unleashed a wave of enlistments, and Confederate officers scramble to organize the influx of volunteers. Yet the celebration is tempered by the realization that Lincoln’s proclamation means a large‑scale war is now inevitable. Both sides begin the rapid, chaotic work of transforming political decisions into military reality.

Across the North, Lincoln’s proclamation ignites a wave of public enthusiasm. Town squares fill with rallies, bands play patriotic marches, and young men volunteer in numbers that astonish local officials. Families gather around newspaper offices and telegraph boards, reading the proclamation aloud and debating what the coming months will bring. The mood is resolute, emotional, and deeply communal — a society awakening to the reality of war.

“Charleston is wild with excitement — the streets thronged with soldiers and citizens shouting for the Confederacy.”

In the South, the news is received with a mixture of triumph and foreboding. Celebrations continue in Charleston and other cities, but Lincoln’s call for troops casts a long shadow. Many Southerners interpret it as proof that the North intends to subjugate them, strengthening support for secession in states still wavering. Families begin preparing for the possibility that their sons will soon march to defend the new Confederacy. The war that began at Sumter now reaches into homes, churches, and public squares across the divided nation.
