I te raumati o te tau 1864 i tohua a Anderson hei koroneela o te 5th Georgia Militia, ana i te marama o Mei ka whakatairangahia ia ki te rangatira rangatira me te whakahau i te 3rd Georgia Militia Brigade. I tukuna tana kaha ki te whakarei i te Ope Taua o Tennessee whai muri i te Pakanga o Kennesaw Mountain i te mutunga o Pipiri, a ka mahi i nga toenga o te Campaign Atlanta. I te 22 o Hōngongoi i te Pakanga o Atlanta
He iti noa iho te kaha o te whakahau a Anderson. I te hinganga o Atlanta, i wehe atu nga ope o nga hoia i te ope taua o Tennessee ka mahi i te haerenga a Sherman ki te Moana i taua hotoke. I uru ia ki te whakaeke a te Confederate i te Pakanga o Griswoldville i te Whiringa-a-rangi 22, i reira "I te arahi i tana pirihimana, i werohia e Anderson ona kakahu ki nga pupuhi, a ka pupuhi tana hoiho i raro i a ia; i tohuhia tana makariri me tana tika i roto i taua pakanga kino". I whara tonu a Anderson i tēnei whawhai.
