Many groups adopted distinct battle flags due to the confusion of the First National Flag which, when furled, looked like the United States Flag. The Polk pattern battle flag, which incorporated a St. George's cross, was designed by Gen. Leonidas Polk, an Episcopal bishop before the war. It was issued to units beginning in January 1862. It incorporated eleven white stars on a red St. George's cross on a blue field. Available in durable cotton only.
