Sure, most people end up in one nice, consolidated grave. But these five generals were not "most people":
1. Gen. "Mad" Anthony Wayne's skeleton and flesh were buried 400 miles apart.
When Isaac Wayne arrived at the Army blockhouse in Erie, Pennsylvania, he expected to exhume his father's bones and take them the 400 miles back to his hometown of Radnor, Pennsylvania for re-burial. His father was Gen. "Mad" Anthony Wayne, a Revolutionary War and Northwest Indian War hero.
When the remains were exhumed, the body was found to be in good condition despite 12 years having passed since Gen. Wayne's death in 1796. Isaac's cart was too small to move a complete body though, and so Isaac had the body dismembered and the flesh boiled off of it. Then, he took the bones the 400 miles back to Radnor. The boiled flesh and the tools used in the "operation" were reburied in Erie.
2. Lt. Gen. Richard S. Ewell was buried 640 miles from his leg.
A Confederate leader in the Civil War, Lt. Gen. Richard S. Ewell was seriously injured at the Second Battle of Manassas. His leg was amputated and buried in a local garden. Ewell returned to combat after a one-year convalescence and was taken prisoner near the end of the war.
He returned to private life before dying of pneumonia in 1872. He was buried in Nashville, Tennessee, 640 miles from his leg.
3. Maj. Gen. Daniel E. Sickles' leg is in the Smithsonian.
Maj. Gen. Daniel E. Sickles led his men to their doom at the Battle of Gettysburg when he ignored his orders and marched forward of his designated positions. Exposed, he and his men were brutally attacked and Sickles himself was wounded by a cannonball to the leg.
After his amputation, he decided against having his leg buried and instead sent it to the Army Medical Museum where Sickles visited it every year. It now resides at the Smithsonian Museum while Sickles rests in Arlington National Cemetery.
4. Lt. Gen. John Bell Hood's leg was buried somewhere by an army private.
Lt. Gen. John Bell Hood lost his right leg after it was struck by a Minie ball during the Battle of Chickamagua in Georgia. His condition after the surgery was so bad that his physician, assuming he would die, ordered Pvt. Arthur H. Collier to take the leg to a nearby town where the general was being treated.
When Hood began to recover, Collier was ordered back to his unit and no one recorded what he did with the leg. Local folklore in Tunnel Hill, Georgia says the leg was buried there, near where Hood spent the first days of his recovery. The rest of Gen. Hood is buried in New Orleans, Louisiana.
5. Stonewall Jackson's left arm has a famous grave.
The grave of General Thomas "Stonewall" Jackson's left arm is well known. Jackson was returning from a reconnaissance of Union positions in 1863 when his own soldiers mistook him for the enemy. Pickets fired on him and injured his left arm which was later amputated.
Stonewall's chaplain buried the arm near Chancellorsville while Jackson was taken to Fairfield Plantation, Virginia. Jackson was expected to make a recovery, but he died of pneumonia eight days after his injury. He is buried in Lexington, Virginia, 44 miles from his arm.
