Which two goals did the Union army achieve?

At the beggining of the Civil War, the Union army had three goals. 1: To form a naval blockade of the Southern ports 2: To gain control of the Mississippi River 3: To take over the Confederate capital of Richmond, Virginia. These first to goals were originally achieved but the invention of the ironclad soon came during the war, and the Confederates used an ironclad, called the Virginia, to wipe out the Union's naval blockade. The third goal was eventually reached when Richmond was taken over by General Ulysses Grant in the Wilderness Battles where he fought with Confederate General Robert E. Lee.
