The dawn of the 19th Century heralded perhaps the greatest explosion of technological development in human history. While technologies in most areas had been advancing slowly for centuries, a little-understood combination of factors combined to radically reshape human societies, developing – for better or worse – faster in one hundred years, than at any other point in human history. Steam engines radically reshaped transport on land and sea, opening broad new ranges of products, both agricultural and manufactured; the telegraph radically altered patterns of human communication; medicine suddenly evolved from speculation and bloodletting to observable and testable practices, radically reshaping human mortality rates. The maturing of electrical power generation, transmission and use resulted not only in the telegraph and the light bulb, but of an early form of fax machine.

In firearms technology, the developments were just as radical. In 1800, the only personal firearms out there were flintlock muskets (aside from some pretty radical one-offs). Less than thirty years later, the percussion cap significantly changed the calculus, by making the musket vastly more reliable. By the end of the 1860’s, self-contained rimfire and centerfire cartridges had begun to dominate the battlefield. Well before the end of the century, smokeless powder and functional machine guns had begun to fundamentally alter infantry warfare.
This steamroller of technological advancement held true in the world of artillery technology, as well. The muzzle-loading cannons of 1800 gave way to breech-loading guns by 1870…Which is where our story actually begins, when artillery met steam power, but off the railroad or warship.
Edmund Louis Gray Zalinski, (1849 – 1909) was a Polish-born American soldier, military engineer and inventor. Born to a Jewish family in Kórnik, Prussian Poland in 1849, he immigrated with his parents to the United States in 1853. Lying about his age to enlist, he joined the US Army and served during the Civil War. Commissioned a 2nd LT in an artillery regiment from the state of New York, Zalinski served on the staff of General Nelson Miles. While not much is known of the details of his exact service, it was apparently enough to see him offered a commission in the Regular Army after the war, which is a notable thing, given the drastic post-war cuts in manpower and budgets. During his career, he served as an artillery officer at the Fort Jefferson military prison in Florida (where he authored an appeal to President Andrew Johnson to pardon Dr. Samuel Mudd, who had been convicted as a conspirator in Abraham Lincoln’s assassination, for the doctor’s service during an outbreak of Yellow Fever at the prison), and as a professor of military science at MIT (the Massachusetts Institute of Technology). During this time, he patented a number of inventions, including an artillery sight.
In 1883, Zalinski witnessed a demonstration of a pneumatic artillery weapon, designed by D. M. Medford of Chicago, Illinois. Zalinski began working on the idea, and eventually designed his own pneumatic gun. While the Army was not initially interested, the US Navy was intrigued. As chemistry had advanced, it had started to create high explosives, that were far more powerful than the older black powder; however, these new explosives were very unstable, and were liable to detonate when fired in a conventional gun. The Navy, wanting to find a way to use the new tool, thought that Zalinski’s new system might be the answer.

In late 1887, the USS Vesuvius was laid down at the William Cramp & Sons yard in Philadelphia, PA; she would be commissioned some six months later. As fitted out, the Vesuvius (named for the Italian volcano) carried three 15-inch “dynamite guns” (a term coined by the press), that could each throw a 500-lbs shell (called a “torpedo”, because – Navy) out to about one-and-a-half miles, adjusting the range by varying the air pressure. Without a war to fight, however, the ship was mostly relegated to the dreaded “dog & pony” circuit, visiting port towns to help them celebrate various holidays. In South America, the Brazilian Navy also fitted a 15-inch model to an auxiliary cruiser named the Nichteroy, which was later sold to the US Navy, which named that ship the USS Buffalo.

Wanting to stay as far ahead of the game as possible, the Navy also commissioned the USS Holland in 1900, to see if an 8-inch version of Zalinski’s gun could be used on a submarine.

Following a two-year stint in the yards for repairs, Vesuvius returned to the fleet in 1897, as relations with Spain worsened. These tensions would soon lead to the Spanish-American War, in 1898. While the Vesuvius performed well in nighttime raids on the Cuban city of Santiago, the ship was saddled with a number of flaws, not least of which was the fact that it was very difficult to aim her main guns, as they were set deep into her hull, instead of being mounted in more conventional turrets. This led the Navy to convert the Vesuvius into a torpedo test vessel in 1904, stripping her of her ”dynamite guns” and replacing them with a variety of torpedo tubes.

As well, the US Army would abandon their experiments with Zalinski’s guns. The Army, which was responsible for coast artillery defense, had installed a number of 8- and 15-inch guns at various forts around the country. But, by 1900, the “dynamite guns” had all been dismounted and sold for scrap.

The reasons for the abandonment of Zalinski’s design are simple: the development of stable high explosives and the limited range of the guns made the “soft-launch” of the pneumatic guns irrelevant, as both issues were easily overcome by conventional artillery. As well, the low velocity of the shells forced them to fire at a high angle, limiting both their accuracy and impact force against armored targets.
While it is neat to speculate on “what if,” the fact remains that pneumatic artillery, although playing an interesting and important role in late-19th Century artillery, has had its day: the support infrastructure to operate pneumatic guns, even using modern technology, is not sufficient for use in combat, even using rocket assist to increase their range.
There’s no reason to reinvent the wheel.
