I would like to see something other than assertion for – ‘considerable industry by international standards’ and how meaningful that is.
Bairoch gives percentage of world Manufacturing as US 9.2% UK 19.9% Germany 4.9% France 7.9, Russia 7.8, Other Developed, 15.7, Other 36.6.
As the CSA ‘industrial’ workforce is around 10% of the US total – 0.9% of world industrial production at the outside ( and way outside at that).
Sorry for the delay in posting here. I've been wanting to address this. Real life, you know.
So, according to Wilson, "as a cotton manufacturing region, the slave states ranked behind the North, England, and France, but above Austria-Hungary, Belgium, Spain, and Finland...while Southern spindles were far fewer than those of the North, they were generally newer and more cheaply operated. A contrast with Britain in 1860 is instructive British mills held about eight times as many spindles as those of the US but produced only about four times as much cloth. The South had about the same relationship to the North.
"'If we treat the South as separate countries and rank them along the countries of the world, the South would stand as the fourth richest nation in the world in 1860'...Southerners possesed more wealth than France, Germany, or Denmark." [I don't know what his definition for Germany is, but I can't imagine it includes anything less than Prussia.]
With respect to the rapid wartime industrialization undertaken by the CS, its impossible to get a complete picture, but some case studies are illustrative. For example, an 1864 survey of factories in NC showed that the state was producing 3,945,432 yards of cotton goods, 531k yards of woolens, and 3,086,100 lbs of yarn. Which was itself 9 million yards of cloth. [Coupled with the remaining factories which had been seized by Governor Vance,] the 13 million yards of cloth and the output of major mills in the lower South alone represented one third of the antebellum capacity of the Confederate States.
In 1861, Confederates had to rely upon massive volunteer efforts to get socks for the soldiers. By 1864,
new sock factories "established in 1863" produced "90 percent" of the needed socks for the troops.
According to Bonner, in 1862, Tredegar produced 981 tons of pig iron, while the CS government was able to supply them with another 855 tons. In 1863, the numbers were 3626 and 1737, respectively. It is of note that Tredegar wasn't focused on the refining of ore into pig iron, but the manufacture of finished metal goods from pig iron.
Interestingly, even with this increase in supply of raw materials, the Tredegar works (which expanded during the war) could never achieve more than 33% capacity.
Another ironworks, the Shelby in Alabama, could produce 10 tones of iron per day in 1860. By 1863, it could produce forty tons per day.
With the available records, I doubt we'll ever have a complete picture of the increase in manufacturing capacity in the CS, but we can know that there was a dramatic increase in their industrial capacity.
And any cursory review of the literature shows that there were many, many, people in the antebellum period who were strongly pushing industrialization. Manufacturers were very important in prewar Southern society.
I don't know why the factories would all disappear in the event of a Confederate victory.
In terms of specific products the US census gives the South ( as at 1 June 1860) a total bar sheet and railroad iron production of 26k or about 10% of Pa alone.
That’s one of the better stats, its abut 7% of Pa Alone for pig iron.
To be fair, PA was by
far the largest producer of pig iron in the US.
On a world scale the US by 1880 makes up 14.7% of world manufacturing. Even if the CSA managed the same spectacular growth as the OTL US pro rata that puts it dwarfed by the Industrial Giant that is Belgium if they are really lucky.
I don't know if you're being flippant there, but Belgium was one of the most industrialized countries in the world in 1860.
But let's look at some postwar data. In 1890, the Southern states produced about 20% of the pig iron in the US. That's about 2 million tons. That's double the output of Russia and Austria-Hungary, 2.5 times the capacity of Belgium, eight times more than Spain, 14 times more than Italy, equivalent to France, and about 1/2 of Germany and 1/4 of the UK. Without the massive losses in wealth brought on by the complete collapse of currency and abolition, I don't know why they would realistically be at a level less than this, and I can think of many realistic reasons why they would be ahead of what they were at IOTL.
