The implication in Lee’s reports that his goals in the Gettysburg campaign were limited, and largely achieved, is at least partly consistent with some modern studies of the campaign. They challenge the traditional view that Gettysburg was a disastrous Confederate defeat that shattered Lee’s hopes for a war-winning victory on Northern soil. They also reject the notion that Gettysburg was a crucial turning point toward ultimate Union victory in the war. According to historians who question these traditional interpretations, Lee’s incursion into Pennsylvania was a raid, not an invasion. A smashing victory over the Army of the Potomac would have been a nice bonus, but it was not the main goal of the raid. The Union victory at Gettysburg was merely defensive, and the Army of Northern Virginia got away with its spoils and lived to fight another day— indeed, many other days, as the war continued for almost two more years. It was only in retrospect and in memory that Gettysburg became the climactic battle and turning point of the war.
Explanation:
Some of these arguments are self-evidently correct. The war did go on for almost two more years, and the Confederacy still had a chance to win it as late as August 1864 by wearing out the Northern will to continue fighting. Rebel foraging parties did scour hundreds of square miles of south-central Pennsylvania for whatever they could find and take—including many African Americans carried back to Virginia into slavery.
The main reason why Congress worked to keep a balance between the number of slaveholding states and free states is because they wanted to avoid war breaking out between the North and the South. They tried to do this through a series of compromises that ultimately failed.
The Constitution provides that an amendment may be proposed either by the Congress with a two-thirds majority vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the State legislatures.
