The term sharpshooter had a more general meaning in the mid-19th Century than it does today. Then it could mean either a roving precision shooter like the modern sniper (a term that did not come into use until late in the century) or a light infantryman who specialized in the petite guerre: scouting, picketing, and skirmishing. The modern sharpshooter (the term comes from the German scharfschutzen, not the use of Sharps rifles) appeared in Central Europe around 1700. At the beginning of the Civil War, thanks to Hiram Berdan, the Army of the Potomac had a definite advantage in sharpshooting and light infantry, and this came as a rude shock to the Confederates during the 1862 Peninsular campaign. In response the Confederates organized their own sharpshooters, beginning with those of an obscure Alabama colonel, Bristor Gayle. Confederate general Robert Rodes organized the first battalion of sharpshooters in his brigade in early 1863, and later in each brigade of his division. In early 1864 General Lee adopted the concept for the entire Army of Northern Virginia, mandating that each infantry brigade field a sharpshooter battalion. These units found ready employment in the Overland campaign, and later in the trenches of Petersburg and in the fast-moving Shenandoah campaign of 1864. Although little has been written about them (the last book, written by a former sharpshooter, appeared in 1899), they played an important and sometimes pivotal role in many battles and campaigns in 1864 and 1865. By the end of the war the sharpshooters were experimenting with tactics that would become standard practice fifty years later. Although most people think of Berdan's Sharpshooters when the subject comes up, the Confederate sharpshooter battalions had a far greater effect on the outcome of the conflict. Later in the war, in response to the Confederate dominance of the skirmish line, the Federals began to organize their own sharpshooter units at division level, though they never adopted an army-wide system. Making extensive use of unpublished source material, author Fred Ray has written Shock Troops of the Confederacy, which tells the complete story of the development of the Army of Northern Virginia's sharpshooter battalions, the weapons they used, how they trained with them, and their tactical use on the battlefield. It also tells the human story of the sharpshooters themselves, who describe in their own words what it was like to be in the thick of battle, on the skirmish line, and at their lonely picket posts.

In recent years there has been a renewed interest in Civil War sharpshooters. Now there is a new perspective on the subject in the story of Major William E. Simmons (1839-1931). The book traces his family heritage and his footsteps from childhood to Emory College, through many challenging war encounters, his capture and imprisonment at Fort Delaware, and a lifetime of service.

During the American Civil War, the Union and the Confederacy both fielded units of sharpshooters. Sometimes equipped with firearms no better than those of their infantry brethren, they fought in a manner reminiscent of Napoleonic-era light infantry. Siege warfare placed a premium on marksmanship and the sharpshooter became indispensable as they could drive artillerymen from their guns. They could also become expert scouts and, for the Confederacy, impressive raiders – one raid netted almost 250 prisoners. Initially, Union marksmen enjoyed the upper hand, but as the Confederates began raising and training their own sharpshooters, they proved themselves as worthy opponents. In this study, Gary Yee, an expert in firearms of the period, assesses the role played by sharpshooters in three bloody clashes at the height of the American Civil War – the battle of Fredericksburg, the siege of Vicksburg, and the siege of Battery Wagner.
