So the slaves were free from Ab Lincon
There was nothing important about Antietam Creek itself. But the loss of the battle that suddenly blew up there was a devastating blow to the South. Not so much in pure battlefield terms. But Lincoln had been waiting for a Union win before he could credibly issue his Emancipation Proclamation - turning the war into an official crusade against slavery. This made it impossible for the British to aid the Confederates without looking pro-slavery themselves.
Probably Antietam. Nearly 12000 were killed in one day. As for the entire war, more than 359,000 Union soldiers died, and 260,000 Confederates.
Debt, loss of market share, and outrageous union benefits costs.
Because he retreated back to Virginia, leaving the field to the Union. More to the point, it was a grievous loss to the Confederacy in general. The British had been treating this campaign as the test of Confederate viability, and began to lose interest in helping the South. Meanwhile it gave Lincoln the credibility to issue the Emancipation Proclamation without making it sound like a desperate measure. After this, free nations abroad could not aid the South without looking pro-slavery themselves.
General Robert E. Lee's invasion of Maryland in 1862 failed primarily due to a combination of logistical challenges and the Union's strategic advantages. The Confederate Army was hampered by supply issues and the loss of critical orders, which were discovered by Union forces. Additionally, the Union Army, under General George McClellan, was able to capitalize on Lee's divided forces and ultimately engage them at the Battle of Antietam, resulting in a costly stalemate that halted Lee's advance. The failure to secure a decisive victory in Maryland diminished the Confederacy's hopes of gaining recognition and support from European powers.
The Battle of Antietam was the bloodiest battle Americans have ever participated in. It occurred on September 17, 1862. More Americans died at the battle than any other battle by the U.S.A. Despite their loss, the Union was able to stop the Confederacy from progressing north into Union territory.
After their loss in the Battle of Antietam countries like France and England no longer believed in a Confederate victory. They saw no point in intervening when a Union victory was much more plausible.
After the loss at the Battle of Chattanooga, Jefferson Davis replaced Bragg with General Joseph Johnston. Johnston's troops would be asked to defend the march of Union General William T. Sherman to Georgia.
The Confederates ran out of men and had to forfit The Confederates did not have the supplies to continue, and they did not have the high ground. Lee was concerned with the Union army blocking his way south, and left before more union troops arrived.
The fall of Atlanta to Union soldiers in September 1864 cost the South an important rail link and a vital center of industry. Atlanta was a critical transportation hub for the Confederacy, facilitating the movement of troops and supplies. Its capture by Union General William Tecumseh Sherman marked a significant turning point in the Civil War, weakening Southern morale and logistics. The loss of Atlanta significantly disrupted Confederate operations and contributed to the eventual Union victory.
The soldiers viewed the Battle of Antietam as a defeat for both armies due to the staggering loss of life and the lack of a decisive victory for either side. Despite being a tactical draw, the battle resulted in approximately 22,000 casualties, which left many feeling demoralized and questioning the war's purpose. Additionally, General McClellan's failure to pursue the retreating Confederate army after the battle was seen as a missed opportunity for a significant Union victory. As a result, both sides were left with heavy losses and no clear advantage, marking it as a grim stalemate.
Following General Lee's retreat back to Virginia after the Battle of Antietam, Union forces were not able to press their advantage of the Army of Northern Virginia's retreat across the Potomac River into Virgina. Here are some examples of the Union's missed opportunities: A. Planned Federal offensives against Vicksburg, Chattanooga, and Richmond failed to be realized and were delayed for up to 7 months; B. When the Union renewed their attempts to press forward late in 1862, they were stalled in Northern Mississippi, Stones River, and Fredericksburg; This series of defeats and delays gave the South some breathing room. The Confederates had a chance to regroup, recruit more soldiers and in general, helped prolong the War. As would be seen by 1864, the South's best chance to survive was to have the North lose its taste for the continued war and the mounting loss of life. Former General McClellan's candidacy as a "End the War" policy he proposed in his run for the Presidency had life as long as the South could continue to hold out. Late Summer victories by the Union, however, dampened the chances for the South's survival.
