Well, Grant under reported his casualities during his 1864 Virginia Campaign and was accused in a congresssional investion of using Black Union Troops as "Cannon Fodder' to reduce his white casualities, because white northern families voted and blacks didn't.

It is believe that Grant actually lost as many men in May of 1864 alone, in the Battles of the Wilderness and Spotslyavania, as KIA, Wounded, POW's, and Missing as Lee had in his Confederate Army.

What do you think? Why do you think that Grant himself said that he couldn't report those numbers, and witheld that information from the Northern newspapers? Grant didn't win a single battle in 1864. He just used his massive armys to move around Lee after each engagement.
