In my novel Brookhaven, I have the 13-year-old Sam McClure sent to the Confederate army in the East. His father had fought with Robert E. Lee in the Mexican American War, and Lee hoped that the young Sam had learned some of his father’s espionage and survival skills. The young man is assigned to a unit called Colby’s Rangers, and after a few weeks of basic training is sent with others to prepare for Lee’s invasion of the North, which culminated in the Battle of Gettysburg.
The model for Colby’s Rangers in the novel is an actual unit called Mosby’s Rangers. It was less involved in espionage and more involved in disruptions of federal lines, camps, and supply lines. When General Jeb Stuart “rode around” the Union army of George McClellan in 1862, it was Mosby’s Rangers leading the cavalry.

Beginning in April 1863, James Joseph Williamson was a private who gained what many Confederate soldiers and cavalrymen desired – a spot in Mosby’ Rangers. Some 44 years later in 1909, he published a memoir of his time with the unit, which stretched to the end of the war in 1865. Mosby’s Rangers: A Record of the Operations of the Fourth-Third Battalion Virginia Cavalry, From Its Organization to the Surrender is the title. and it was republished as an e-book in 2018. (It’s also available as an audio book.)
Memoirs of the Civil War by soldiers were common in the late 19th and early 20th centuries. The Civil War generation was dying out, and much of the story had not been told. Generals had been their memoirs published; Ulysess S. Grant’s memoirs were a bestseller. But now it seemed it was the soldiers and lower officers who were publishing accounts “from the ground level.”
Williamson published two editions in his lifetime; the second corrected errors and added information. He had kept a diary during the war years, and the diary became the basis for the memoir.
It’s a highly readable, interesting, and often thrilling account. John S. Mosby was a Virginian attorney when he joined the Confederate Army. He caught the eye of Jeb Stuart, and he soon became known as one of Stuart’s key men. Mosby’s Rangers operated primarily in the Shenandoah Valley and northern Viriginia, he it’s fair to say they ran circles (literally and figuratively) around Union armies.

He was nicknamed the “Gray Ghost;” his cavalrymen could slip through enemy lines almost like phantoms. One of the most famous of the Rangers’ exploits was in March 1863. In the early morning hours, a group of 30 Rangers led by Mosby discovered a break in Union lines. They traveled several miles to Fairfax County Courthouse and captured Union Brigadier General Edwin Stoughton, two captains, 30 soldiers, and nearly 60 horses without a shot being fired to a man lost. And then they made their way back to Confederate lines. The story electrified the South and outraged the North; it also earned Mosby a promotion. After Stuart’s death, Mosby reported directly to Lee.
Williamson was one of the 29 men who accomplished “the impossible raid,” and his account is riveting.
Mosby survived the war, despite a bounty placed on his head by Grant. Impressed by what Mosby had accomplished, Grant would pardon him when he became President. They became friends, and Mosby – to the dismay of his Southern fans – became a Republican and worked to unify the country. His popularity diminished rapidly.
Mosby’s Rangers is a great story, told first-hand by a man who was there and saw it happen.
