I’m not saying pacifist leaders. I’m saying that the combination of Grant and Sherman was unique among the Union generals for their strategic and tactical vision, their willingness to take casualties to achieve it, and in the case of Sherman, the sheer audacity to target the CSA economy and infrastructure as a war aim by marching through Georgia without guaranteed supply chains.
If Grant and Sherman die in mid 1864, they won’t be replaced by pacifist generals, but who amongst the Union generals would have been so competent and driven?
