Where was Tom Robinson sent to after his court appeal?

After the trial, Tom was taken to Enfield Prison Farm, which was about 70 miles away. This is where he would attempt to escape and be shot to death.

His chances were slim to none that he would have won his appeal, and he would have been sentenced to die at that point. Tom took his chances at the only chance of freedom he would have, although surely he must have realized he would not have much chance of being successful at an escape.
