Cold Harbor is often viewed similar to Fredericksburg. Why?

The Battle of Cold Harbor is often viewed as similar to the assault on Marye's Heights during the Battle of Fredericksburg (1862) because of how lopsided the casualties were.

Explanation:

The Battle of Cold Harbor (1864) was one of the bloodiest, most uneven battles in American history, as many Union soldiers died or were wounded in a disastrous confrontation with the fortified area of the army led by Confederate Gen. Robert E. Lee.
