“It was no longer a question of the Union as it was, that was to be reestablished; it was the Union as it should be, that is to say, washed clean from its original sin, regenerated on the baptismal font of liberty for all. … Now, we could march with a prouder step, and fight with more confidence. We were no longer merely the soldiers of a political controversy, to be decided by the fate of arms. We were now the missionaries of a great work of redemption, the armed liberators of millions of men bent beneath the brutalizing yoke of slavery. The war was ennobled; the object was higher.”
