How does this artwork elucidate its Exception?
One notable exception to the list may be the earliest Texan recipient, Milton M. Holland. He was born a Texas slave in 1844 and served with the Fifth U.S. Colored Troops during the Civil War.  On September 29, 1864, during an attack in which all his unit's officers were killed or disabled, Sergeant Major Holland took over despite his own wounds, and led his comrades to take the Confederate position near Richmond, Virginia.  He was awarded the Medal of Honor on April 6, 1865, and at his death in 1910 was interred at Arlington National Cemetery.
