During Grant's war of attrition, it was bad that the Union army stayed on the offensive because their defensive positions each time were poor. Their number of casualties grew poorer each time that they battled. But, despite this, Grant believed that the Union's supplies and manpower could overwhelm the Confederacy. Grant predicted that this war of attrition would weaken the Confederacy. Finally, there was no winning of neither side, but future consequences, as the Confederacy came to an end.
