Fort Sumter Howitzer
In this Tuesday, Dec. 11, 2012 photo, a mountain howitzer like those used in the final months of the Confederate defense of Fort Sumter in Charleston, S.C., rests on a fort rampart. The howitzer was returned to the wall this week after its old wooden carriage was replaced with a new $12,000 steel carriage that is a replica of the original. (AP Photo/Bruce Smith)
