Greatest impact on atlanta after the civil war

Hi! :)

The destruction of railroads.

Back then, we still hasnt developed air transportaions, so most of resource delivering and product distribution that carried out by the companies were utilized through the railroad.

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature
