Why did Grant decide not to return to Washington but to instead continue attacking Lee after the Bat?

After the Battle of the Wilderness, Ulysses S. Grant chose not to return to Washington because he believed that continuing the offensive against Robert E. Lee was critical to wearing down the Confederate Army. Grant aimed to maintain pressure on Lee's forces, preventing them from regrouping and reinforcing. He recognized that a decisive victory was essential to ending the war, and he was determined to pursue a strategy of attrition, leveraging his superior resources and manpower to achieve that goal.
