In June 1796 the Government purchased from the Harper heirs a 125-acre tract of land and began constructing workshops on the benchland between the Potomac River and what would later become Potomac Street. Waterpower was harnessed by building a dam upstream from the armory and channeling the water through a canal into the workshops. Although a critical shortage of gunsmiths and ordnance-making machinery restricted operations for several years, limited arms production began late in 1798 under the direction of an English Moravian named Joseph Perkin, the armory’s first superintendent.

The first muskets, based on the old French infantry type of 1763, were completed in 1801. In 1803 production was expanded to include rifles, and 2 years later the manufacture of pistols. (The Model 1805 pistol, made at Harpers Ferry, was the first hand weapon to be produced at a United States armory.) At first the rate of musket production was meager, but by 1810 the armory was turning out 10,000 annually, storing them in two arsenal buildings nearby on Shenandoah Street.

In 1819 John Hall, a Maine gunsmith, received a contract from the Federal Government to manufacture 1,000 breech-loading flintlock rifles of his own design. Sent to Harpers Ferry, he set up the Hall Rifle Works in two buildings on Lower Hall Island, which adjoined Virginius Island in the Shenandoah River about ½ mile from its junction with the Potomac. Hall’s rifles were made on so exact a scale that all the parts were interchangeable—a factor that helped to pave the way for modern mass production methods. The War Department was elated with Hall’s success and his contract was repeatedly renewed. When the Hall rifle was discontinued in 1844, the Government tore down the old buildings and erected a new rifle factory on the same site. Standard U.S. Model rifles were produced there until the industry was destroyed, along with the armory complex, at the outbreak of the Civil War in 1861.

The abundance of water power that had attracted the arms industry soon brought others. Besides the rifle factories on Hall Island, Virginius Island boasted an iron foundry, flour mill, cotton mill, and machine shop, all powered by water diverted through the island by a dam in the Shenandoah River and a series of sluiceways and underground water tunnels. More than 200 persons made their home around the prospering island industries.

The formation, development, and expansion of the United States Armory and Arsenal at Harpers Ferry (its complete, official designation) was the chief stimulus for the growth of the town. From a simple beginning the armory by 1859 had spread to include 20 workshops and offices, lined in a neat double row over an area 600 yards long. At its peak, the armory provided employment for more than 400 men, mostly transplanted Northerners whom local residents classified as “foreigners.” In the 65-year history of this major industry, the U.S. Government invested nearly $2 million in land, water power improvements, walls and embankments, hydraulic machinery, and buildings.

HARPERS FERRY AND VICINITY 1859

After 1830 Harpers Ferry, already recognized as an important industrial center, attained prominence as a vital link in the transportation and communications line between the Ohio and Shenandoah Valleys and the East. By 1830 a semi-weekly stagecoach service connected the town with Washington, D.C. The one-way trip usually required a full day’s travel. That same year a turnpike company was founded to construct a 16-mile macadamized toll road from Harpers Ferry to Middleway, 5 miles west of Charles Town. A turnpike being built from Frederick, Md., about 20 miles to the east, reached the town in 1832. Still another turnpike company, organized in 1851, ran a road from Harpers Ferry southeastward to Hillsborough, about 10 miles away.

But the signal impetus to the establishment of the town’s commercial position was the arrival of canal and railroad. Waging a bitter battle to reach the rich Ohio Valley and carry its trade to the East, impeding each other’s progress at every opportunity, the Chesapeake and Ohio Canal (originating in Washington, D.C.) and the Baltimore and Ohio Railroad (originating in Baltimore, Md.) reached Harpers Ferry in the early 1830’s. Following the winding Potomac River northward and westward from Georgetown, the C & O Canal arrived at Harpers Ferry in November 1833, more than a year ahead of its rival. But the railroad pushed on to the Ohio Valley while the canal stopped at Cumberland, Md. The establishment of these two arteries provided shippers with a cheaper carrier for their products and assured travelers of a more efficient and economical means of reaching their destinations.

With the expansion of industry and the development of superior transportation facilities, the population of the community swelled to nearly 3,000 by 1859. Of these about 150 were “free coloreds” and 150 were slaves. The total number of slaves in the entire six-county area around Harpers Ferry was just slightly more than 18,000, of which less than 5,000 were men. There were no large plantations because the land and the climate could not sustain a plantation economy. The few slaveholders maintained farms, and their blacks were mainly “well-kept house-servants.”
