Overland campaign 1864
Just looking at some figures concerning casualties,
General Lee holds a pretty even number of combat soldiers
verses the number of losses he has. Now I am sure there
are some differing figures as these came from the battle report
on Wikipedia. But I do find this interesting.
Wilderness total engaged 61,000
total casualties 11,000
Spotsylvania total engaged 52,000
total casualties 13,421
North Anna total engaged 53,000
total casualties 2,517
Cold Harbor total engaged 59,000
total casualties 4,595
Lee's army ends up with practically the same number of combatants as he did at the beginning of the overland campaign.
