When thinking of the ocean-going navy of the Southern
Confederacy in the American Civil War the image immediately comes to mind of
fast, largely unarmoured vessels such as the Alabama and the Florida,
general similar in construction terms to commercial vessels, albeit
strengthened to carry heavy armament. The corresponding image of a Confederate
ironclad is, by contrast, an armoured, improvised, steam-propelled raft
intended for service in rivers and coastal waters. It is therefore somewhat of
a surprise to learn that the Confederacy’s last “Blue-Water” naval vessel was a
heavily-armed ironclad, well capable of sinking any major Union warship she
encountered. Completed late in the Civil War, only the end of the conflict brought her potentially devastating career in Confederate service to an end only
just as it was starting. This was however to be just the prelude to spectacular
battle-service in a newly created navy on the other side of the world.
CSS Stonewall |
The ship that was to
become the CSS Stonewall was one of
two ironclads constructed in France, personal approval for the project being
given in 1863 by the Emperor Napoleon III, who was sympathetic to the
Confederate cause. The objection that French neutrality would be compromised by
delivery of warships to either the Union or to the Confederacy was neatly
side-stepped by circulation of the rumour that they were intended for delivery
to the Khedive of Egypt – the appropriate names of Sphynx and Cheops were
allocated to them. A further element of confusion was added by ensuring that
the armament would come from Britain. The seagoing ironclad concept was a new
and revolutionary one at the time – France’s Gloire and Britain’s HMS Warrior,
the first of the type, had been launched in 1859 and 1860 respectively – so the
Confederacy was betting on acquiring cutting-edge naval technology.

Sphynx and Cheops were of 1358 tons and some 190
feet long. Their 1200-hp steam engines, driving two screws, gave a top speed of
over 10-knots. Twin rudders made for very tight turning circles – a decided
advantage at a time when combat was likely to be at very close range. They also
carried an auxiliary sail rig – especially valuable for conservation of coal
when operating over long distances. The most notable feature was however the
heavy armour protection – a waterline belt with thickness ranging from 3-5 to
5-inches or iron, as well as some 5-inches on the redoubts fore and aft in
which the armament was housed. These latter structures were not rotating
turrets, but rather protective casemates from which the guns fired through
ports. As such they could be regarded as precursors of the later “central
battery” type of ironclads, as compared with the traditional broadside
arrangement of the earlier Gloire and
Warrior. Sphynx
and Cheops each carried a single 300-pounder
muzzle-loading Armstrong forward, firing over the pronounced ram-bow, with two
68-pounder weapons in the after redoubt. As such they were built to absorb
tremendous punishment as well as to deal it out.

The vessels were constructed in Bordeaux, on France’s
Atlantic coast, and were launched early in 1864. Human greed is however a major
obstacle to keeping a project of this sort secret. In this case the subterfuge about purchase by Egypt was exposed by a clerk at the shipyard who supplied information on the deal –
and hard evidence, in the form of documentation – to the United States
ambassador in Paris. With a diplomatic
crisis about neutrality brewing, the French Government had no option but to
block the sale. A new customer was immediately available however. Prussia’s
“Iron Chancellor”, Otto von Bismarck, supported by the Austro-Hungarians, had
precipitated war with Denmark. Heavily outnumbered, the Danish resistance was
fierce, heroic and doomed. The bright spot for Denmark was the performance of
its navy, both in support of land operations and on the open sea. (My blog of 8th January 2016
regarding the Battle of Heligoland refers. It can be found via the sidebar).
It was accordingly inevitable that both the Danes and their enemies should be
looking to purchase more warships. Sphynx
and Cheops would fit the bill to
perfection. In a cynical deal in which a sale to one side was balanced by a
sale to the other, the Sphynx was
sold to Denmark – and renamed Stærkodder
– while the Cheops was purchased by
Prussia and called Prinz Adalbert.
Thus were neutrality concerns elegantly sidestepped!

A Danish crew arrived in Bordeaux in June 1864 to start
acceptance trials and take her to Denmark thereafter. (One wonders if there
were any embarrassing encounters with a Prussian crew arriving to take over Prinz Adalbert!). The war was however
winding down – with Denmark comprehensively beaten – and by 1st
August a preliminary peace treaty had been signed. By the time Stærkodder arrived in Copenhagen all was
over and she was by now essentially surplus to the requirements of the
vanquished nation.
Confederate agents had however followed the Sphynx/ Stærkodder affair with interest
and were still determined to acquire her. Negotiations – which must have
required a high degree of secrecy – resulted in a sale by Denmark and in early
January 1865 a Confederate crew commanded by Captain Thomas Jefferson Page (1808
– 1899) took delivery. The ship was commissioned at sea as the CSS Stonewall.
These events had not gone unnoticed by Union agents and
diplomats and once intelligence was obtained of the Stonewall’s “breakout” from the Baltic to the North Sea, and on to the
Atlantic, powerful Union Navy units were despatched to find and sink her. There
are strong parallels with the breakout of Germany’s battleship Bismarck
in 1941 and her hunting by Royal Navy forces. Among the Union ships deployed
were the steam-sloop USS Kearsarge –
recently the victor of her duel with the CSS Alabama off the French coast – and her sister USS Sacramento, supported later by the
steam-frigate USS Niagara. Though Kearsarge had been partly protected by
improvised chain-armour, all these ships would have been at a decided – and
perhaps fatal – disadvantage in any duel with the heavily-armoured Stonewall.
Once at sea the Stonewall
developed a leak – it is notable that her now-Prussian sister Prinz Adalbert deteriorated so rapidly
that she was taken from service in 1871 – and she put in at Quiberon, on
France’s Brittany coast, where repair possibilities see to have been limited,
and to take on supplies and further crew members. It is likely that many of
these recruits were not American, as was the case also with other Confederate
raiders, but men of other nationalities who were attracted by pay and by the
opportunity for adventure. Stonewall
now pressed on to Ferrol, in North-West Spain, where she could undertake
repairs. She remained there for almost two months. Word of her presence spread
and the USS Sacramento and USS Niagara took up station outside. (One is
reminded of HMS Shannon lying off
Boston in 1813, daring the USS Chesapeake
to come out).

When the Stonewall
did finally emerge from Ferrol on 24th March, the Union warships
waiting for him declined to engage – wisely, in view of the disparity in
armament and armour. Captain Page now
headed for Lisbon, Portugal, to take on coal prior to a dash across the
Atlantic to attack Port Royal in South Carolina, the supply base for the Union
General Sherman's army. The Stonewall
was followed into port by the Sacramento
and Niagara – which under neutrality rules
could only glower at each other in enmity. An attempt by the Niagara to shift her berth was
interpreted by the Portuguese authorities as a potentially hostile move against
the Confederate vessel and warning shots from cannon on the castle of Belem put
an end to the manoeuvre. Formal neutrality rules – demanding that enemy ships
could not leave harbour simultaneously – were strictly applied and the Stonewall slipped away unmolested.
Time was running out for the Confederacy however. On 9th April
Lee surrendered the Army of Northern Virginia to Grant and on 26th April the
only other major Confederate force was surrendered by Johnson to Sherman. By
the time that Page and the Stonewall
put in at Nassau, in the British possession of the Bahamas, on 6th
May the epic conflict was at an end. The ironclad and her crew were now
orphans.
Page now decided to take his ship to Havana, in Cuba, then
still a Spanish possession. He handed her over to the government authorities there
against a payment of $16,000 and paid off her crew. The Spanish in turn handed
the Stonewall to the United States in
return for a similar payment.
The triumphant Union now possessed one of the most powerful
warships afloat, but in the aftermath of the Civil War there was little
appetite for retention of a large navy – the concern was indeed to run down one which had grown to gigantic
levels during the conflict. The Stonewall
lay decommissioned at the Washington Navy Yard for some two years until it was
decided to sell her.
And the buyer?
Opened up to foreign contact only thirteen years before, the
Empire of Japan was engaged on a furious, and historically-unprecedented,
campaign of modernisation. Its ambitions were all but boundless and acquisition
of an effective navy was of the highest priority. The ex-Confederate ironclad
would be ideal for their purposes.
The Stonewall
would be heading east, and under a new name - Kōtetsu - would embark on the most active
part of her career.
I’ll tell about that in the second part of this article, which
will appear soon. Watch out for it!
