CLEP U.S. History I 097: Major Campaigns and Turning Points
U.S. History to 1877 | Chapter 18 | Lesson 18.2
First Bull Run ended hopes for a short war. In the West, Union victories at Forts Henry and Donelson opened routes into Tennessee. New Orleans fell in 1862. Antietam stopped Lee’s first northern invasion and gave Lincoln the opportunity to announce preliminary emancipation. In 1863, Gettysburg ended Lee’s second invasion while Vicksburg gave the Union control of the Mississippi. These victories did not end the war, but together they narrowed Confederate strategic choices.
Grant’s 1864 Overland Campaign imposed terrible losses while maintaining pressure on Lee. Sherman captured Atlanta, strengthening Lincoln politically, and marched through Georgia to damage transport, supplies, and Confederate morale. “Turning point” should be used carefully: it identifies a change in strategic direction, not a moment after which no uncertainty remained.
The western and eastern theaters interacted. Vicksburg severed a major trans-Mississippi connection. Gettysburg ended an invasion but did not destroy Lee’s army. Atlanta mattered because military news affected the 1864 presidential election and therefore the future of Union war policy. A turning-point claim is strongest when it names the mechanism,territorial control, army loss, diplomatic effect, or political consequence,instead of treating fame as proof.
Modeled chronology Antietam,preliminary proclamation,Vicksburg/Gettysburg,Atlanta,Appomattox. Link each event to its consequence instead of memorizing dates alone.
