At the Battle of Cold Harbor, General Lee won his last victory over Union forces, numbering 108,000 against his 59,000. On this day federal troops lost 7,000 men against 1,500 for the Confederate troops. In an eight-minute period more men fell in an assault on entrenched Confederate troops than in any other like period of time. Between May 7 and June 3, federal losses were 50,000 men, Confederate 32,000. The North could replace its losses fully, but the South could not.
