Answer:
Chattanooga and Atlanta were both railroad hubs.
Step-by-step explanation:
back in ye olden days, people have cars and planes and interstates and things like that, but they did have trains. trains were a lifeline for the south at the time. Think about what would happen to say.... Valdosta if I-75 was shut down. they would be in ruin because they wouldn't be able to get enough food and supplies into the town to support the population. the same was true with the rail system, but if they took and Atlanta, they cut off the whole states from supplies, not just one town.
