Death of Polk
At Pine Mountain, Georgia the battery was ordered to fire on a cluster of Confederate officers in an exposed area spotted by Major General William T. Sherman. The officers were Generals Leonidas Polk, William J. Hardee, Joseph E. Johnston and their staffs. Sherman pointed them out to Maj. Gen. Oliver O. Howard, commander of the IV Corps, and ordered him to fire on them. Captain Simonson obeyed the order within minutes. The first round came close and a second even closer, causing the men to disperse. A third shell struck Polk's left arm, went through the chest, and exited hitting his right arm then exploded against a tree; nearly cutting Polk in two.
