Black Union soilders were fighting for the freedom and liberty of slaves.

"it will not be long before we shall crushed the system that now opreses you for in the course of three months you shall have your liberty..." Document #3 (Letter from a black Union soilder)

Samuel Cabble is writing to his wife how he will crush the system that opressed them for such a long time. This system is the white Americans of the confederacy that hold slaves and force them to do countless of unfair tasks for them. He is stating in this letter that the Union army will reach the place where they are held in a course of three months and that he will free her from the oppression of slavery. This is yet another example that the black people where fighting to free slaves. Frederick Douglass and other abolonists saw that without a good enough cause they would not fight in the war, then they stated that the war would only be justified if it were made to end slavery. Abolonists leaders would constantly try to persuade Abraham Lincoln to make the war a crusade against slavery, by the end of the war they had succeeded, the war was a battle fought to end slavery over uniting the states (Document #1). The fifty-fifth Massachussetts regiment (blacks) lead by Colonel Shaw participated in a scuicide misson to capture one of the Confederate forts in order to end slavery in the area (Glory). Many died including Shaw himself, another example of the reason the blacks fought. The blacks fought the Civil War to destroy the oppresion of slavery.
