In the early morning hours of April 3, 1865, Richmond, Virginia, was burning. The Confederate government had fled, President Jefferson Davis and his cabinet having boarded a train heading south. The army was gone, and the retreating forces had set fire to the warehouses to keep their contents from falling into Union hands. As dawn broke, an ammunition depot exploded, shattering windows blocks away.
And 350 armed men stood before an ironworks, watching the flames approach. These men belonged to the Tredegar Battalion, a home-defense unit made up of European-born workers from the factory. Their employer, Joseph Reid Anderson, had kept them posted around the complex all night to stop anyone from torching it. Behind them stood the most important industrial site in the Confederacy, a foundry that had manufactured roughly half of all the artillery produced within the South.
But the gun foundry itself was silent. It had been shut down for five weeks, not because Richmond had fallen, but because the iron, the skilled labor, and the money had all run out at once. A factory that had armed a nation for four years now sat dark and guarded on the night that nation died. The Confederacy had enjoyed four years to build alternatives, and it had tried.
By 1864, major weapons factories operated in Selma, Macon, Augusta, and Columbus, new plants placed hundreds of miles from Richmond, deliberately out of reach of Union raids. Yet none of that expansion ever ended the reliance on Tredegar. The question is not why no one attempted a replacement, but why four years of determined effort failed to produce one. The answer lies in understanding what it actually took to make a cannon.
The process began with iron ore dug from a mountain in western Virginia, smelted in a blast furnace with limestone and coke, and shipped down the James River and Kanawha Canal to Richmond. At Tredegar, the metal was melted again and poured into a mold packed in sand inside a heavy iron container. The cannon came out as a solid block. After cooling for a day, it was moved to a lathe, where a machine cut the bore through the solid iron with precision measured in fractions of an inch.
It was then tested with an overloaded charge to see if it would burst. Finally, it received its carriage, wooden components, iron fittings, and wheels before shipment. Every step took place in a separate building, required a different set of skilled workers, and carried its own risk of failure. Lose the ore and nothing starts.
Lose the coke and the furnace cools. Lose the lathe and you have a lump of iron shaped like a cannon that could not hit its target. Lose the carriage shop and you have a cannon that cannot move. Tredegar controlled all of it under one management.
The mines were in the mountains, the furnaces outside the city, the mills along the river, but it was one company, one chain of command, one schedule. In the spring of 1861, no other factory in the South came close. You could decide to build a second furnace. You could decide to build a second foundry.
But you could not decide to create a second ore field, a second coking operation, a second canal, and a second generation of men who knew how to cast a barrel without a flaw, and then make all of it work together on a single timeline within four years. The Confederacy did not lack ambition in 1861. It lacked depth, and depth is not something that can be ordered. The Confederate government began the war in Montgomery, Alabama, but by May 1861 it had moved to Richmond.
The political reasons are well known, but beneath them lay an industrial reason that the men in Montgomery understood. Richmond was where the cannons were. If the Confederacy wanted to fight a war, its government had to be in the same city as its only advanced arsenal. They moved the capital to the factory.
Tredegar had been chartered in 1837 by Richmond businessmen who wanted to sell iron to railroads. They named it after an iron town in Wales and brought Welsh ironworkers to build the furnaces, because that was where the skill resided. The company nearly died immediately. The financial panic of 1837 ruined it, and the engineer who designed the plant was killed in a street fight in Richmond the following year.
The firm struggled for four years. Then in 1841, the owners handed management to a 28-year-old civil engineer named Joseph Reid Anderson, a West Point graduate of 1836 who had left the army for business. He leased the works, then bought them outright, and by 1860 Tredegar had become the largest iron producer in the South. In 1847, Anderson made a decision that shaped everything that followed.
His white workers went on strike, demanding higher wages and the removal of enslaved men who had begun appearing in the iron-smelting jobs. Anderson fired the strikers and replaced them. By the start of the war, Tredegar employed about 900 workers. White laborers remained the majority in 1861, but enslaved labor had become a critical part of the operation.
Some of the enslaved men Anderson owned outright. Others he hired annually from their owners, much as a company would lease equipment. They worked in the rolling mill, the foundry, the forge, and the carpentry shop. Some were foremen, and the company paid their owners more for the skilled ones, because their skill was real.
This was not a southern accident; it was a management strategy. Enslaved workers could not legally leave their employers or bargain for better terms, solving Anderson’s labor problem by binding workers in place. Fourteen years before the war forced the rest of the South to need the same solution. War expanded the system.
As white workers were conscripted into the Confederate army, Tredegar replaced them with enslaved laborers. By 1863 the workforce had grown to 2,500, more than half of them enslaved. That November, the company placed an advertisement in the Richmond Daily Dispatch: it wished to hire 1,000 enslaved people for 1864 to work in the Tredegar ironworks in Richmond, at blast furnaces in Rockbridge, Botetourt, and Alleghany counties, and in the coal mines of Goochland and Henrico. One thousand people.
The advertisement specified where they would go, including those mountain counties two hundred miles west where the ore was located. Sending someone there meant removing them from the city, from any family they had, to a company furnace in the hills. By November 1864, records show roughly 200 enslaved people at the Richmond site and several hundred more at the mountain furnaces. The company’s private papers, in dry administrative language, note that many of those sent to the mountain counties died there, ran away, or were never delivered at all.
So when it is said that Tredegar made nearly half of the artillery produced by the Confederacy, those are the hands that made it. The smelting, casting, rolling, and heat were not nameless and not incidental. These are the people who stood before those furnaces. Building a second Tredegar would have required a second workforce, and the Confederacy did not have one.
The army was conscripting men from the fields. The foundries were drawing men from those same fields. And the farms feeding both were losing labor all the time. You can build a building.
You cannot build a population. During the war, Tredegar produced approximately 1,100 artillery pieces, about half of everything manufactured inside the Confederacy. The expansion was real. By 1864, the Selma works in Alabama were casting heavy guns, including its own Brooke rifles, and employing thousands.
Other plants throughout Georgia and Alabama were producing as well. So why did none of it change the equation? In part because of what Tredegar made: the heavy pieces, the coastal defense guns, the siege guns, the large weapons of cast and wrought iron that took the longest to manufacture and could not be improvised. Those were the hardest things to produce in the Confederacy, and the new plants reached that capability slowly.
The new factories needed the same things Tredegar needed: ore, coal, skilled hands, and money, and those resources were not becoming more abundant. And in part, it came down to one machine more than anything else. Tredegar had a rolling mill that could do something no other ironworks in the South could do at all, and it held that advantage for the first half of the war. In 1861, the Confederacy raised the wreck of a burned Union frigate at Norfolk and decided to rebuild it as an ironclad.
The design required rolled iron plates two inches thick, bolted over a sloping wooden hull. There was one small problem: no factory in the South could roll plates of that thickness and width. So Tredegar rebuilt its rolling mills to do it. By the time the ship was finished in early March 1862, Tredegar had rolled 723 tons of two-inch armor plate for it.
The CSS Virginia, called Merrimack by the North, sailed on March 8 and fought the Union blockade fleet over two days in battles that heralded the end of the wooden warship era. Every inch of that armor came from Tredegar’s mills. No other place in the South could have made it. This was what dependency actually meant.
The collapse did not begin on the battlefield. On May 15, 1863, fire swept through the complex. The boring mill, where the rough cast barrels were finished, was badly damaged. The locomotive shop, the forge, and many machine shops burned, along with the adjacent Crenshaw wool mill, which made uniform cloth and was never rebuilt.
The boring mill was the critical loss. Without it, Tredegar could not properly finish new gun barrels, and the company had to move unfinished barrels across town to the naval ordnance works at Rockets to complete them. Then the copper ran out. Bronze is an alloy of copper and tin, and the Confederacy drew the vast majority of its copper from the Ducktown mines in Tennessee near Chattanooga.
In November 1863, Union forces seized that region. The bronze 12-pounder Napoleon, the most useful field gun in the Confederate arsenal and the weapon that did most of the work in most major battles, could no longer be made. Tredegar’s foundrymen did what skilled metalworkers do when their materials disappear: they developed an iron version of the Napoleon. It worked.
It was heavier and not as good. The numbers tell the rest. In the first six months of 1864, Tredegar cast 128 guns. In the last six months of 1864, it cast 85, and most of those were, in the language of the records, of questionable quality.
A factory dying in real time. It was not just copper. By the end of 1864, the Confederate government owed Tredegar enormous sums. The Nitre and Mining Bureau alone was behind by $300,000.
The Ordnance Department had not settled its accounts since October. The Navy and the Railroad Bureau were far behind as well. Confederate currency had been declining for two years, and the government paid its bills in that currency, late, if at all. Tredegar still had to buy ore, coal, coke, food, and labor with the same collapsing money.
In December, the company asked the government to take over operation of its own blast furnace, not for expansion but to shed the cost of running it. In January, the works shut down for two weeks for repairs that no one was being paid to make. By February 1, 1865, Tredegar held unpaid invoices exceeding one million dollars. Anderson was forced to borrow $100,000 just to meet the first month’s payroll.
On March 1, 1865, five weeks before the war ended, production at the gun foundry stopped entirely. Not because Richmond had fallen, not because the furnaces had been destroyed, but because the iron, the skilled labor, and the cash were all gone at the same time, and none of it could be obtained anymore. Anderson knew what was coming: retreating troops executing orders to burn everything the enemy could use, and a factory full of weapons, machinery, and iron. He had argued for months that Tredegar should be exempt from destruction.
There was opposition within the Confederate government, but Anderson succeeded, and the ironworks was never officially designated for burning. He did not rely on that alone. He kept the Tredegar Battalion, those 350 armed workers, posted around the complex. That night, Richmond burned.
The retreating Confederates set fire to the depots, the fire spread, the ammunition magazine exploded, and by morning much of the commercial district was gone. A mob approached Tredegar but found armed men who would not move, so they went elsewhere. When it was over, the ironworks still stood, one of the very few industrial sites in the city to survive. Two days later, on April 4, Abraham Lincoln walked through the ruins of Richmond.
He visited the Confederate White House and sat in Davis’s chair. He met with men to discuss the condition of the city, among them Joseph Reid Anderson, the man whose ironworks had armed the rebellion Lincoln had spent four years suppressing. Anderson received a pardon, not from Lincoln but from President Andrew Johnson, in September 1865. He had been transferring money abroad during the war, shipping cotton through the blockade, and holding the proceeds in a sterling account in London.
That capital, which had never been Confederate currency, helped him regain control. He was back in business before the end of 1865, regained full ownership in 1867, and Tredegar continued producing iron for another ninety years. A fire in 1952 destroyed much of the old plant, and operations on the James River finally ended in 1957. Why did four years of expansion never end the reliance on Tredegar?
Because building Tredegar had taken a full generation. Chartered in 1837, it was still struggling four years later, and it did not become the largest iron producer in the South until 1860, twenty-three years after its founding. The Confederacy had only four years. You cannot clone a workforce to meet a deadline.
Anderson’s skilled hands had taken decades to assemble, and the war tore them apart. White workers were conscripted. Enslaved workers remained because they had no other choice, and their numbers grew as the fighting continued. They did the hottest, hardest work at Tredegar, and many of those sent to the mountain furnaces died there or fled when the army finally arrived.
And you cannot finance a new factory with currency that is collapsing. By 1864 the government could not pay its suppliers, let alone find capital to build another plant. Three things cannot be manufactured to a deadline: time, people, and money. Five weeks before the end of the war, the gun foundry went silent.
The final accounting: 1,100 cannons, 723 tons of armor, 2,500 workers, then nothing but cold iron waiting in the dark for the fire to arrive. The North did not simply have more factories than the South. It had surplus, other factories, other valleys, other towns that could pick up an order when a foundry burned. The South built new works too, and they helped, but when Tredegar faltered, there was nothing else in the Confederacy that could carry what it carried.
There was no second place that could do it all.
