As a result of union and confederate casualties during the battle of gettysburg, both armies could no longer wage war effectively. lee’s army was weakened for the rest of the war. the confederate army decided to surrender. the union army decided to surrender.

Neither of the armies surrendered immediately after the Battle of Gettysburg, but Lee's army was weakened for the rest of the war due to the limited amount of people and lesser population in the South. The Battle of Gettysburg was also where the Pickett's March occurred, which was a suicidal march the Confederate General Pickett ordered during this battle. There was a total of 57,000 casualties within three days.

If i’m not mistaken your answer should be the freemen’s bureau started them. i really hope i could ! good luck
