How the Confederate soldiers were treated after the Confederate surrender?

Answer 1

Most Union forces were welcomed home with festivities and parades. The South had little to celebrate and some returning soldiers returned to their homes and farms to find them in ruins. Some of these turned to outlaw ways likes the James and Youngers. Others headed West to begin new lives.

Answer 2

"they returned home in peace and taking there this they loved with them"

^This is true, but a better explanation is that he:

Grant offered generous terns to surrender, after, laying down their arms the Confederats could return home in peace, taking their private possessions and horses with them. Grant also gave food to the hungry Confederate soldiers.

Answer 3

Remarkably leniently.

Grant told Lee that if the Army of Northern Virginia handed in their weapons and went home, they would not be persuecuted and Lee would not be jailed.

Lee was so impressed with this gesture that he would not hear a bad word against Grant for the rest of his life.

As for Sherman, taking the surrender of Joseph E. Johnston in Carolina, he offered even more generous terms, because he thought that these were what Lincoln would have offered. But Lincoln was dead by then, and the new President Johnson was not prepared to ratify them. This caused some discord during Reconstruction.
