Patrick Cleburne
Patrick Ronayne Cleburne was an Irishborn American soldier, best known for his service in the Confederate States Army during the American Civil War, where he rose to the rank of major general.
Cleburne was born in Ovens, County Cork, Ireland, the second son of Dr. Joseph Cleburne, a middleclass physician of AngloIrish ancestry. Patricks mother died when he wasmonths old, and he was an orphan at 15. He followed his father into the study of medicine, but failed his entrance exam to Trinity College of Medicine in 1846. In response to this failure, he enlisted in the 41st Regiment of Foot of the British Army, subsequently rising to the rank of corporal.
