What reasons did the Confederacy have for believing they would have a quick victory?

Question: What Reason Did the Confederacy have in believing they would have a quick victory in the Civil War.

The South had a better trained army at the beginning of the war which is indisputable given the results of the first major battle of the war. The South also had a more talented officers corps in the most important theatre of the war, the East. Much of the Union officer talent was confined to the Western theatre and would take years to emerge from the Union officers political environment. The South's best officers were already established in command. Stonewall Jackson, JEB Stuart, Longstreet were already in place at First Manasas. That's three of the Confederacy's four most important Generals already in place. Lee would emerge as their overall command (June 1, 1862) years before the Union would cycle through half a dozen disastrous and incompetent commanders, finally promoting Grant(March of 1864). When Grant eventually did come East, he brought Sheridan and Sherman with him.

These early Southern advantages were apparent in the first major battle of the war (First Battle of Bull Run) when the South routed Union forces which fled back to Washington dc in total disarray. JEB Stuart pursued the Union army all the way to Alexandria without meeting any resistance. He was close enough to the city to see the Union's pickets. General Mcclellan who picked up the pieces of the Union Army after Bull Run is not treated kindly in history; but one thing he is given credit for is rebuilding the army of the Potomac after that catastrophe.

The Union's advantages at the onset of the war were economic, production, and population; all of which would take time to assert themselves in a war of attrition. If the South had kept the war from becoming such a war, they had advantages which they could use. The south could have won a political victory by sewing together victories and sapping the union's bifurcated will to wage the war. The South also could have won by capturing the Capital of DC and thus paralyzing the Union.

The Union did not have an advantage in officers or training of their army.

Why did the Confederacy think they would win easily? At first Bluster, but after Bull Run they had reason to believe the war would be a quick one. Many people believe Confederacy lost the Civil war at the battle of first Bull Run. The Union Troops were in a panicked unorganized flight back to DC. Reforming that mob into an army capable of defending the capital would take time. General Joe Johnston the confederate general in charge of the battle had used 1 army corps to defeat the Union that day. He had an entire army corps in reserve all formed up and ready to attack DC. The confederacy lost the civil war when General Joe Johnston decided not to pursue the union troops into the nearly undefended capitol and capture the union leadership. Stonewall Jackson wounded at Bull Run in the hand is said to have walked the camp seeking 200 men to follow him into Washington. He believed he could have ended the war with just 200 men (taken the Whitehouse ). I don't know about that, but with an entire Army Corps behind him, many believe the south could have won the entire war, in the very first major battle. This is a premise I first heard put forward by Col John Mosby, chief scout for General JEB Stuart in his autobiography. Col Mosby, an enlisted man at the beginning of the war, was at Bull Run that day, one of the second army Corps who weren't used.

The civil war was lost when the war became one of attrition. In such a war the Unions advantages became insurmountable.

To somewhat echo other answers: The advantage of not having to win was considered very significant, as it usually is but I guess it was not enough in this case. Also, the South thought that the production of cotton would be somehow a very important factor but this was wrong (although not completely so since indeed cotton was one of the few things that the South had going for it) since other parts of the World also produced cotton. But the question of belief is somewhat subjective and I will give an opinion: I don't think the Southern leadership was particularly sophisticated. Late in the war, they seemed to think, even though they were certainly ambivalent about it, that arming the slaves would help them when there was every reason to believe this would not work at all. Jeff Davis was a good soldier but I think he was in over his head in his position and his sole competent advisor as far as I can tell was Judah P. Benjamin who himself frankly might have been in over his head.

Before the war, the South was hoping they wouldn't have to fight at all; that, upon weighing the pros and cons, the North would just leave them alone (this proved to be true - for a while).

If, however, the North did go into battle against them, the idea was that just as with the American Revolution, when a country of four million souls took on the mighty Empire and won, the South, with over five million people, could wear down the North, whose heart wasn't in it, their superior numbers notwithstanding.

The South did have the better commanding officers. However, they reckoned without the North's unlimited resources which minimized the importance of winning individual battles. Despite the South's dramatic victories, the Union Army just kept coming.

The "scorched earth" tactic employed by General Sherman undermined the South's will to fight. No one in the South had foreseen that.

In addition to the reasons already given above, the South also believed that Europe could not survive without Southern cotton. At the beginning of the war, Southern merchants organized a cotton embargo to provoke Britain to enter the war on their side. However, Britain had sufficient stocks of cotton to last a year, and was already working to develop alternate sources of supply in Egypt. The overwhelming support for the Confederacy that southerners expected in Britain never materialized.

Who had the better trained army??? Greater part of officers were Southerns. That was the reason why they thought they would win. And really, during all the war the command of the Southern army was incomparably superior. But they really needed a quick victory, because of the weaker economy. And failed to obtain it. And their tactical superiority helped them only to last the agony.

Their first and main thought was that there would be no fight, for they had all rights to make their own country. After all, not far before the whole USA had appeared the same way.

The second thought was that they would win any fight, for they simply had the majority of the officers. And volunteers always fight better than privates or soldiers of fortune.

And the third was that they were RIGHT and thus they couldn't lose. After all, the North only wanted to build its economy on their account. And the God would surely make them win, as they were the good ones.

Notice, I am not saying those are facts, but that is what Southerners took for facts. And the question is about their common beliefs.
