Few realize the world’s first widespread deployment of landmines took place during the American Civil War (1860–1865). At the start of the Civil War, the disparity in military manpower, materiel, and weaponry between the North and South was significant. The gap widened in the Union’s favor as the war progressed, forcing the Confederate war industry to innovate and improvise. That was especially true with landmines. As the conflict progressed, landmine warfare advanced commensurately, and both tactics and technology evolved to include innovative types of design and deployment. During the war’s later years, Confederate soldiers used both command-detonated and victim-activated landmines more frequently to defend and to protect static positions, including cities.1
At the outset of the Civil War in April 1861, the United States war strategy emphasized the occupation of key Southern harbors, the conquest of the Mississippi River to divide the enemy, and the establishment of a naval blockade around the Confederacy. Within a few years, the Union had established a fairly tight blockade along the coast, and it was no longer possible for the Confederacy to export cotton in large quantities. The South’s “white gold” failed to produce the income needed to help prevent the depreciation of its currency and fund the war effort.
The South’s economy was based on agriculture, and there were few industries capable of producing the war materials the Confederate government needed to fight the war ahead; thus, it had no choice but to seek more creative ways to fight, including leveraging low-cost weapons with minimal material input. One of the solutions to holding key pieces of Southern territory was the development of landmines from a variety of artillery shells, with increased technological ingenuity adapted to local circumstances. Confederate soldiers eventually configured spur-of-the-moment landmines in a relatively ad-hoc manner. Details were rarely written down, and most of what was recorded was destroyed near the end of the war to avoid the possibility of some leading advocates being charged as war criminals. The simplicity and cost-effectiveness of landmines made their continued use attractive. Today we call these buried or hidden artillery rounds improvised explosive devices or IEDs.2
