Final answer:
The provided texts do not mention how Stonewall Jackson was injured in "John Brown's Body". Historically, General Jackson was accidentally shot by his own troops and died of pneumonia after his arm was amputated. The answer cannot be precisely provided from the provided information but is based on a well-known Civil War fact.
Step-by-step explanation:
The question seems to be asking how Stonewall Jackson was injured, which pertains to a historical event. However, based on the provided texts, there is no specific mention of Stonewall Jackson being injured in the song "John Brown's Body" or in the provided reference excerpts. The texts discuss various battles and strategies during the Civil War but do not detail the circumstances of an injury to Jackson within those particular events. Thus, the information needed to directly answer the question is not present in the given materials.
However, it is a known historical fact that General Thomas "Stonewall" Jackson was accidentally wounded by his own men at the Battle of Chancellorsville in May 1863. This event is not described in the provided texts but is well-documented in Civil War history. Jackson was returning to camp after scouting enemy positions at night when he was mistaken for a Union cavalryman and shot by Confederate soldiers. Despite efforts to treat him, he succumbed to pneumonia eight days after his arm was amputated.
