Following the bombardment, Lincoln mobilized forces to suppress the rebellion and restore the union.
Lincoln, a moderate Republican, had to navigate a contentious array of factions with friends and opponents from both the Democratic and Republican parties. His allies, the War Democrats and the Radical Republicans, demanded harsh treatment of the Southern Confederates. Anti-war Democrats (called "Copperheads") despised Lincoln, and irreconcilable pro-Confederate elements plotted his assassination. He managed the factions by exploiting their mutual enmity, carefully distributing political patronage, and by appealing to the American people. His Gettysburg Address came to be seen as one of the greatest and most influential statements of American national purpose. Lincoln closely supervised the strategy and tactics in the war effort, including the selection of generals, and implemented a naval blockade of the South's trade. He suspended habeas corpus in Maryland and elsewhere, and averted British intervention by defusing the Trent Affair. In 1863, he issued the Emancipation Proclamation, which declared the slaves in the states "in rebellion" to be free. It also directed the Army and Navy to "recognize and maintain the freedom of such persons" and to receive them "into the armed service of the United States."
