Atlanta was evacuated by the Confederate Army of Tennessee (Maj. Gen. Hood commanding) on 1 September 1864 and occupied by the Union Armies of the Tennesse and the Cumberland the following morning (Lt.Gen.W.T. Sherman commanding).
Sherman rested his armies in that city for 2 and a half months while accumulating supplies for further campaigning. Supply of the Union armies in that city was difficult due to a single track railroad line to Chattanoga TN. Sherman therefore split his forces, putting a corp under Maj.
Gen George Thomas to protect Tennesse and taking his remaining force on a forced march to Savannah Georgia in order to be supplied by sea by the US Navy (The March to the Sea). On November 14, 1864 details of the Army of the Cumberland set fire to all buildings, workshops and storehouses that may be of use to the Confederate cause.(The Burning of Atlanta). The next day the Union Army left Atlanta giving the burnt out hulk of the city back to Confederate control.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
