Stonewall Jackson's arm

Stonewall Jackson's arm is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Stonewall Jackson's arm rather than just read about it. In short: Confederate General Stonewall Jackson was wounded at the Battle of Chancellorsville on May 2, 1863, and his left arm was amputated by Hunter McGuire. Chaplain Beverly Tucker Lacy had the arm buried at Ellwood Manor.

Key takeaways

  • Stonewall Jackson's arm belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Stonewall Jackson's arm to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Stonewall Jackson's arm from memory before moving on to harder problems.

Reference excerpt

Confederate General Stonewall Jackson was wounded at the Battle of Chancellorsville on May 2, 1863, and his left arm was amputated by Hunter McGuire. Chaplain Beverly Tucker Lacy had the arm buried at Ellwood Manor. Jackson died on May 10. Confederate staff officer James Power Smith had a granite monument erected for the gravesite of the arm in 1903, although it is not known how accurately Smith's marker represents the true location of the arm. Legend holds that American military officer Smedley Butler had the arm exhumed in 1921, although the factual accuracy of this story is dubious. While it is unknown where the arm is now located, or if it even still exists, the marker has become a tourist site.

Jackson and the amputation

Thomas J. Jackson was born on January 21, 1824. He attended West Point, and after graduating in 1846, served in the United States Army, including in the Mexican–American War. In 1852, he resigned from the army and began teaching at the Virginia Military Institute. After the start of the American Civil War in 1861, Jackson became an officer in the Virginia militia and joined the Confederate States Army. At the First Battle of Bull Run, he gained fame and the nickname "Stonewall". Serving as a high-ranking officer in the Army of Northern Virginia under Robert E. Lee, Jackson fought in a number of battles and became well known. On May 2, 1863, in the Battle of Chancellorsville, Jackson led his force on a successful flank attack against the Federal army. While scouting in front of his own lines the night after the flank attack, Jackson was shot in a friendly fire incident. He was wounded in three places: one in the right hand and two in the left arm. A few hours later, Hunter McGuire examined Jackson's wounds, and determined that his left arm needed amputation. Jackson was sedated with chloroform, and the arm was cut off near the shoulder.

While helping prepare the wounded Jackson to be moved from the battlefield for his safety, chaplain Beverly Tucker Lacy noticed Jackson's arm, wrapped up and intended to be buried in a ditch with other amputated limbs. Believing that the arm deserved a better fate, Lacy had the arm buried at Ellwood Manor (a home owned by Lacy's brother), in the family plot there. The general was not informed of the limb's burial. Jackson died of pneumonia on May 10. Jackson's widow was asked if she desired the exhumation of the arm so that it could be buried along with the general, but declined after being assured that the arm had received Christian burial. The next year, on May 6, during the Battle of the Wilderness, a Federal soldier reported in his diary that some of his fellow soldiers had exhumed the arm and then reburied it, although the location of the reburial is not known. A granite marker was placed to the marker in 1903 by former Jackson staff officer James Power Smith. It is not known how accurately this marker reflects the actual burial site of Jackson's arm. Other markers placed by Smith at battlefields are, in the words of the National Park Service (NPS), "quite approximate in nature". The marker bears the words "Arm of Stonewall Jackson May 3, 1863". Despite the cemetery containing the graves of 15 people, the only grave monument is the one for the arm.

Smedley Butler In 1921, a force from the United States Marine Corps conducted a large mock battle at the Wilderness battlefield, led by American military officer Smedley Butler. Among the visitors were President of the United States Warren G. Harding and his wife, Florence Harding. The Hardings stayed at Ellwood during their visit, and Florence was reported to have visited the burial site of Jackson's arm. By the late 1930s, a story from the family who owned Ellwood had begun to circulate claiming that Butler had been told of and disbelieved the claim that Jackson's arm had been buried at the site, and ordered an excavation made by a squad of Marines. The tale claims that Butler and the Marines found the remains of the arm and had it reburied in a metal container. Further versions of the story have claimed that the arm received a 21-gun salute upon reburial. One account claims that Butler filed a report about what had happened, but no such report has been located. Family history also claims that Butler revisited the site long after the 1921 mock battle. While the story about Butler's 1921 visit is repeated on a historical marker near the site, and has been often published, the factual accuracy of the legend is disputed. Ellwood came under the control of the NPS in 1977 as part of the Fredericksburg and Spotsylvania National Military Park, and the NPS conducted an archaeological study at the site. The study found no evidence of disturbed earth around the marker, and NPS attempts to locate a metal container with a metal detector have failed to detect any such container. A 2010 NPS press release included the conclusion "the arm was never dug up. It certainly was not reburied in the box near the marker" and expressed a belief that the Butler story was false. The press release also noted the NPS had failed to find documentation supporting the story from before 1940. A historian for the NPS has also rejected claims that the arm was stolen, or that it is located in storage somewhere.

Worked examples

Example 1 — a first encounter with Stonewall Jackson's arm

Start with the simplest possible case. Write down what Stonewall Jackson's arm claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Stonewall Jackson's arm before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Stonewall Jackson's arm ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Stonewall Jackson's arm

In research
Stonewall Jackson's arm appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Stonewall Jackson's arm in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Stonewall Jackson's arm is common in secondary-school and first-year university syllabi. It links to neighbouring topics American Civil War medicine, Amputation, Arm, so understanding it makes those chapters shorter.
In everyday life
Look for Stonewall Jackson's arm outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
