Who led destructive march through georgia?

For all practical purposes the three Union armies under the command of Major General William T. Sherman did not "march through Georgia". They battled their way under fierce resistance from Confederate forces.The General William T. Sherman was the highest ranking Union general to lead the march through Georgia. His first main target was Atlanta. The city surrendered in early September, 1864, helping President Lincoln's re election campaign.

Sherman made that city his headquarters for almost two months. He then began his famous or to some, his infamousmarch to the sea, towards the port city of Savannah. He ordered Atlanta burned to the ground upon his departure, however, Catholic priests begged him to spare hospitals, which he did spare.

Savannah surrendered on December 21, 1864.
