What did General Sherman's March entail? Why did it cause such lasting resentment?

The purpose of Sherman's March to the Sea was to frighten Georgia's civilian population into abandoning the Confederate cause. Sherman's soldiers did not destroy any of the towns in their path, but they stole food and livestock and burned the houses and barns of people who tried to fight back.
