  Title: Robert Johnson Henderson
  Passage: Robert Johnson Henderson (November 12, 1822 – February 3, 1891) was a Confederate States Army colonel during the American Civil War (Civil War).  His obituary stated that he was made a brigadier general by General Joseph E. Johnston, after Johnston witnessed Henderson making a desperate charge at the Battle of Bentonville, North Carolina, on March 10, 1865.  At the suggestion of his divisional commanders, Henderson signed his parole as a brigadier general.  Later, Henderson stated in his pardon application that he had been recommended for promotion to brigadier general but had never received a commission.  Henderson commanded a brigade for several weeks at the end of the war but never was officially appointed by Confederate President Jefferson Davis and confirmed by the Confederate States Senate to brigadier general rank.
  Title: 32nd Arkansas Infantry Regiment
  Passage: May 1862 found Confederate Arkansas, with almost no organized army facing an invasion by forces under Union General Samuel R. Curtis.  In March, Major General Earl Van Dorn had been ordered to move his Army of the West, via riverboats to the east side of the Mississippi River to reinforce Confederate forces near Corinth, Mississippi, leaving the state of Arkansas with no organized Confederate forces.  Major General Thomas C. Hindman was dispatched to Arkansas to assume command of the Department of the Trans-Mississippi, arriving in Little Rock on 31 May 1862.  Earlier in the month, Confederate Brigadier General John S. Roane, who had been left in command in Little Rock by General Van Dorn, had managed to stop a Texas Cavalry Regiment that was traversing the state to join General Van Dorn in Mississippi.  This gave General Hindman one organized Cavalry Regiment to attempt to stop General Curtis's force from moving from Batesville, which had been occupied in early May, south to the state capital.  Fortunately for General Hindman, the Confederate Congress had passed a Conscription (Draft) law in April 1862.  The passage of this law had two effects that would help Hindman.  The first, the law provided a method of pressing manpower into the Confederate Army through conscription or threat of conscription.  Second, the law required that all existing Confederate regiments be re-organized, with new elections for officers, but gave the existing officers the option of resigning rather than standing for re-election.  Many of the regimental officers serving in Arkansas regiments east of the Mississippi river chose to resign and follow General Hindman back to Arkansas and assist in the raising of new forces.  This gave Hindman an officer corps around which to build his new army.
  Title: Benjamin Hardin Helm
  Passage: Benjamin Hardin Helm (June 2, 1831 – September 21, 1863) was a Kentucky politician, attorney, Confederate brigadier general, and a brother-in-law of Abraham Lincoln.

He attended the Kentucky Military Institute and the West Point Military Academy and then went to study law at the University of Louisville and Harvard University.  He served as a state legislator and the state's attorney in Kentucky.  He also served as the assistant inspector-general for the Kentucky state guard.  Helm was offered the position of Union Army paymaster by his brother-in-law, President Abraham Lincoln, a position which he declined.  Helm felt it was an honor to serve in the Confederate States Army, where he was initially a colonel and later promoted to brigadier general.  Helm commanded the 1st Kentucky Brigade more commonly known as The Orphan Brigade.  He died on the battlefield during the Battle of Chickamauga.  Helm was married to Emilie Todd, the half-sister of Mary Todd Lincoln.

  Title: Benjamin Franklin Gordon
  Passage: Benjamin Franklin Gordon (May 18, 1826 – September 22, 1866) was a Confederate States Army colonel during the American Civil War (Civil War).  Gordon had been a private and bugler for a Missouri regiment serving in the U.S. Army during the Mexican-American War.  Gordon served in the Confederate Army under Brigadier General Joseph O. "Jo" Shelby in Missouri and Arkansas in the Confederate Trans-Mississippi Department throughout the war.  On May 16, 1865, with the war coming to an end, General E. Kirby Smith, as the Confederate commander of the Trans-Mississippi Department, assigned Gordon to duty as a brigadier general.  The Confederate government took no action on the appointment and Confederate President Jefferson Davis did not officially appoint and nominate Gordon to the rank of brigadier general because the Confederate Senate last met on March 18, 1865 and Davis was captured by Union troops on May 10, 1865.  Although he was only aged 40 at his death, Gordon survived the war by little more than a year.
