However, I'm not listing only campaigns and battles, but also relatively minor engagements, of which Grant's assaults on Vicksburg certainly qualify.

Grant's assaults on Vicksburg May 19 & 21 cost the Union 85% of the total casualties and killed in action they would experience during the siege which ended July 4.
For Confederates, it was the reverse -- 20% of CSA killed & wounded at Vicksburg happened during Grant's initial assaults.
These bring the war's totals to date, by my count, to over 362,000 casualties, including over 42,000 killed in action.
