Artillery Through the Ages: A Short Illustrated History of Cannon, Emphasizing Types Used in America

In Short

This book serves as a technical and historical primer on the development of artillery, specifically focusing on the types of cannon utilized throughout American history. Beginning with the emergence of gunpowder in Europe and concluding with the transition into modern ordnance, the text details the mechanical evolution of guns, the chemistry of propellants, and the tactical realities of the gunner’s trade. Written with a focus on preservation and public education, it functions as both a historical narrative and a practical guide for identifying artillery displayed in National Park sites.

The Story

The narrative begins with the "ancient engines of war" and the arrival of gunpowder in Europe, marking the end of the bombard era. As casting techniques improved after 1470, the heavy, cumbersome pieces of the past gave way to lighter, more mobile ordnance. By the mid-1500s, standardization became a priority, with the French leading the way in regulating calibers. This technological migration reached the New World with Columbus, and soon, Spanish fortifications across the Americas were heavily armed with bronze and iron pieces, often decorated with elaborate Renaissance motifs.

The story moves across the vast, often impenetrable American wilderness, where the weight of heavy guns made water transport a necessity. In the absence of ships, artillery was frequently abandoned, as seen during the 1702 siege of St. Augustine. As the narrative reaches the American Revolution, the focus shifts to the improvisation required by the Continental forces. Cut off from European imports, the colonies turned to their own rudimentary foundries, eventually fielding a diverse, if chaotic, array of calibers.

The arc of the story then bends toward the mid-19th century, a period defined by the dramatic rise of rifling. The introduction of the Armstrong breechloader and the American Parrott rifle fundamentally altered siege warfare. While these weapons offered unprecedented range and accuracy, they also highlighted a persistent tactical paradox: despite their power, neither rifles nor smoothbores could effectively destroy well-constructed earthworks. The defenders of Fort Sumter, for instance, proved that masonry ruins could be repurposed into nearly invulnerable earthen fortifications.

The final movement covers the transition into modern artillery at the end of the 1800s. The emergence of steel as the preferred material, alongside perfected recoil mechanisms and smokeless powder, ushered in an era of unprecedented lethality. By the time of the First World War, artillery had become the dominant force on the field, accounting for the vast majority of casualties. The book concludes by emphasizing the long-term historical legacy of these machines, encouraging readers to view the surviving specimens in national parks as tangible witnesses to this rapid, brutal, and transformative progression of military technology.

How It Unfolds

The dawn of ordnance The narrative traces the shift from heavy, primitive bombards to refined, standardized cannon in the 16th century. Improvements in casting and the introduction of trunnions allowed for greater maneuverability and elevation, setting the stage for organized field artillery.

Colonial limitations In early America, the dense wilderness and lack of infrastructure dictated that heavy guns travel by water. When ships were lost or blocked, these vital weapons were often abandoned, defining the tactical constraints of intercolonial warfare.

The Revolution and improvisation The onset of the War of Independence forced the colonies to develop domestic founding industries. Washington’s forces relied on an eclectic mix of bronze and iron pieces, maneuvering them into position through sheer manual labor and drag ropes.

The rifled revolution Mid-19th-century developments, specifically the introduction of the Parrott rifle and its reinforced breech, drastically increased range. These weapons changed the face of siege operations, though they proved surprisingly ineffective against simple, resilient earthworks.

Modernity and precision The transition to steel, high explosives, and sophisticated sighting mechanisms pushed artillery into the modern age. The Prussian success at Sedan demonstrates the devastating potential of massed, mobile fire, which reached its grim peak during the First World War.

The People

The historical figures mentioned serve as conduits for the evolution of the gunner’s art. Emperor Ferdinand represents the early military commanders who recognized that success depended on balancing heavy battery power with light, mobile field pieces. Sir Francis Drake appears as the archetypal adventurer, seizing ornate bronze cannon as trophies from early Florida outposts, underscoring the high value placed on these weapons.

Luis Collado acts as a voice of reason from the past, warning princes and founders that failure to account for a gun's specific purpose leads to disaster. His obsession with "fortification" and the proper wall thickness of culverins highlights the transition from haphazard craftsmanship to systematic engineering. John Müller emerges as the 18th-century expert whose treatises became the standard for English and American artillery, attempting to strip away "useless" ornamentation in favor of weight-saving design.

Finally, the American inventor Robert P. Parrott stands as a symbol of the mid-19th-century industrial shift. By developing his wrought-iron reinforced cast-iron guns, he enabled the Federal army to project power across immense distances. Collectively, these men—whether commanders, theorists, or inventors—are defined by their struggle to master the volatile chemistry of black powder and the stubborn, often dangerous physics of molten metal.

In Its Own Voice

"Sometimes the adventurers seized cannon as prizes, as did Drake in 1586 when he made off with 14 bronze guns from St. Augustine's little wooden fort of San Juan de Pinos."

This illustrates how artillery served as both essential defense and prized loot during the early colonial period.

"A delayed action shell, diabolically timed to roll amongst the ranks with its fuze burning, was calculated to 'disorder the stoutest men,' since they could not know at what awful instant the bomb would burst."

The text describes the psychological impact of early explosive projectiles on infantry.

What It's Really About

The central argument posits that artillery development is a cyclical struggle between the weight of metal and the power of chemistry. It asks how a society balances the need for mobility—essential in the rugged American terrain—with the demand for the massive, stationary destructive force required for sieges. Beneath the technical descriptions lies a deeper observation on the nature of military progress: that technological superiority does not always equate to tactical victory, as evidenced by the inability of expensive, long-range rifles to overcome simple, well-maintained earthworks. Ultimately, it is a study of how human ingenuity, driven by the necessity of survival, slowly refined a crude, dangerous invention into a dominant instrument of modern industrial war.

Why Read It Today

This book is essential for those who visit national battlefield parks and wonder about the silent iron sentinels standing on the ramparts. It provides a rare, grounded perspective on the mechanics of history, stripping away romanticized notions of war to reveal the difficult, often dirty, and highly technical labor that fueled it. You will feel the weight of the iron and hear the commands of the drill, as the author meticulously explains everything from the "side boxes" on a carriage to the specific danger of hot shot.

However, a reader should be prepared for the book's intense technical focus. It does not shy away from jargon, including tables of bore thickness and long lists of specific ammunition types, which may feel dense to a casual reader. Furthermore, the prose reflects a mid-20th-century government publication style—direct, functional, and occasionally dry. The author’s emphasis on the "inhumanity" of early chemical weapons or the "discomfort" of besieged troops serves as a reminder of the era's attitudes toward war, offering a stark, unvarnished look at the transition into the total-war paradigm of the 20th century. It is a rewarding, precise volume for anyone who appreciates the intersection of engineering and human history.
