HAT ARE THE ENDURING 

lessons of the history of coastal 

defence, for the attacker as well as the defender? Part of the 
intellectual problem which both specialists and historians 
have in taking a balanced view of this discipline is that, 
since Mahan, it has been very hard to find evidence of 
coastal defence being among the classic preoccupations of 
maritime thinkers concerned with grand strategy. The tra-
ditional view, to the extent that any serious intellectual 
consideration was given to the subject at all, was that coastal 
defence was merely a mechanistic adjunct to the main 
game: you either had enough destroyers, torpedo boats, 
minefields, guns and troops to defend your shoreline - with 
air support to match - or you didn't. According to t h i s  out-
look, more complex and subtle coast defence calculations 
were meaningless and anyway, since 1940, they summoned 
up unkind parallels with 'Maginot line' thinking and could 
hence be safely overlooked.

 

The result, more often than not, was that with the excep-

tion of those countries which demonstrated an understand-
ing of the strategic value for themselves of an integrated 
coastal defence, very few countries took coastal defence 
seriously at all until they had to - or until it was too late.

 

But, as this study has tried to show, from the floating 

batteries of the Crimean War to the unwieldy monitors and 
ironclads of the American Civil War, from Prince Albert to 
Devastation, purpose-designed coastal warships have had an 
influence on the development of naval design far greater 
than their humble original purposes might at first have 
indicated.

 

Though there were some Americans who were so  bed-

azzled by the new technology that they believed their 
monitors could take on far more powerful European advers-
aries, most realistic observers of the time knew well the 
limitations of these craft. And yet, Monitor  proved to be 
both an inspiration, a source of desperation - and a deter-
rent. One important major study of the Battle of Hampton 
Roads which unfortunately only came to the author's atten-
tion after the main body of this book was written describes 
the impression which both Monitor  and her redoubtable 
opponent  Virginia  created in the minds of those who saw 
them, served on them, or fought against them.

 

Monitor caused desperation to her crew simply because of 

her very low freeboard. Her paymaster wrote that: 'Our 
decks are constantly covered with a sea of foam pouring 
from one side to the other as the deck is inclined, while at

 

short intervals a dense green sea rolls across with terrible 
force, breaking into foam at every obstruction offered to its 
passage'

That the Union had felt obliged to so rapidly construct 

what was essentially an armoured, steam-powered raft to 
defend her ports and coast against Confederate marauders 
was a reflection of her weakness at the outset of the Civil 
War. Despite her implicit industrial strength, the Union 
lacked the iron-cased seagoing warships which were begin-
ning to grace the fleets of France and Britain. America's 
foremost shipbuilder, Donald McKay, had called for a US 
response to European progress, saying: 'It would be easy for 
us to build in one year, a fleet of 500 to 600 men-of-war 
ships, from a gunboat to the largest of iron-cased frigates'

This  was of course somewhat optimistic, especially when 
more sober minds were concentrated on simply trying to 
keep one particular frigate, the Merrimack, out of Confede-
rate hands. This effort failed. Merrimack  was transformed 
into the ironclad Virginia,  and the inconclusive Battle of 
Hampton Roads in 1862 was the result.

 

William Davis' book makes a number of interesting ob-

servations. One is that John Ericsson's design for Monitor 
was only one of six designs for turrets vessels to be submit-
ted to Commodore Joseph Smith's examining board

3

. An-

other illuminating sideline is that the original contract 
called for the vessel to be capable of making six knots under 
sail!

 A further point is the sheer strangeness of Monitor's 

appearance to anyone who saw her at the time. One such 
observer, upon setting eyes on the curious Union vessel, 
was moved to say that: 'No words can express the surprise 
with which we beheld this strange craft, whose appearance 
was tersely and graphically described by one of my oars-
men, "A tin can on a shingle."'

Whatever the fallbacks of Monitor and its contemporaries - 

and both Monitor  and  Virginia  came to ignominious ends -
their layout and concept nevertheless inspired a line of de-
velopment which ultimately culminated in the Sverige,  the 
Dhonburi  and the Vainamoinen  and, via different lines of 
development, both the Dreadnoughts and all the battleships 
of the first half of the twentieth century.

 

The idea of mustering some tantalising, equaliser of a 

force on a small or modest hull with which to overcome a 
more powerful warship is as old as maritime warfare. But 
the classic coast defence ship, either when included in a 
balanced fleet or when it led a fleet, and when it was built in

sufficient numbers, could contribute to a very meaningful 
'fleet in being'. Powerful navies, like France's for instance, 
considered them as essential adjuncts to the main fleet. 
Lesser navies had few other options and, realistically, the 
construction of effective coastal defence battleship fleets 
was the only credible strategy.

 

But the fact is that only a very few countries managed to 

develop such strategies and construct meaningful flotillas of 
these vessels. Sweden had a dozen coastal battleships in 
service in 1906 (after the launching of Oscar II in the pre-
vious year), while France had no fewer than fifteen (of very 
mixed capabilities) in the same year. But the latter were 
part of a much larger fleet, originally constructed very much 
with a British threat in mind. By 1906, following the com-
missioning of Dreadnoughtand the establishment of the 'En-
tente Cordiale' with Britain two years before, many of these 
vessels' original purpose had been eradicated. Neverthe-
less, some proved useful in the First World War, as shown in 
Chapter 7.

 

Yet only Sweden and, arguably, Denmark and the 

Netherlands with their nine coast defence ships apiece in 
1906, ever had a truly meaningful coast defence battleship 
force at any one time. In the Danish case, some of the 
vessels still around in the early twentieth century were very 
old. The rest of the coast defence navies never had more 
than a handful, or fewer, of the type at any one time. Nor-
way had four ships from 1900 to 1940, while the Thais had 
four in the late 1930s (if you include the two 886 ton 
Ratanakosindra class vessels, that is).

 

So, if their numbers were so small in most countries, what 

was the point of having them at all? Why not simply spend 
money on, say, an armoured cruiser (very popular around 
the turn of the century), or a mixed fleet of destroyers, 
submarines and, at the most, cruisers in later years?

 

The latter approach was precisely the course chosen by 

the Netherlands, although this was more by default as that 
country's ambitious plans to build capital ships, first battle-
ships and later battlecruisers, never came to anything. The 
former approach of reliance on armoured cruisers was partly 
chosen by the likes of Argentina and Spain, although the 
Spanish learned at Santiago in 1898, in a very painful man-
ner, just why armoured cruisers could not be a  credible 
answer to battleships with superior gunnery and armour.

 

But what could have been an answer, in the right loca-

tion, might have been a coast defence ship with armour 
comparable to the battleships of the period. In the context 
of this debate, the decision to design or build modern coast 
defence ships after the Sverige class is more significant. Fin-
land 
with the Vdindmoinens, and Denmark with its stillborn 
concepts of the 1930s, showed that very considerable bat-
teries and respectable armour could yet be provided on 
small shallow draught hulls.

 

It may be of interest to readers that a useful source of 

information on Ingenieur-Kantoor voor Scheepsbouw (IvS),

 

the Dutch firm which designed Vdindmoinen,  is William 
Manchester's massive study of the German armaments and 
steel family Krupp. This describes in detail how the restric-
tions of the Versailles Treaty were evaded by the establish-
ment of IvS - 'the heart of Krupp's Dutch complex' - in 
The Hague 'with the approval and co-operation of Admiral 
Behncke's Marineleitung in Berlin'. A careful reading of 
these pages establishes a strong indirect link between 
Vdindmoinen and the 'Panzerschiff Deutschland

.

 

In the light of such impressive designs and concepts, it is 

tempting to wonder what might have happened at Narvik in 
1940 if the Norwegians had been equipped with modern 
vessels comparable to the Vaindmoinens. There seems little 
doubt that, in capable hands, two such vessels might have 
wiped out the German destroyer force which fell upon Nar-
vik that April. Whether a better-equipped Norwegian fleet 
could have altered the course of history, or at least the 
Narvik campaign, is of course a moot point, although there 
is no shortage of opinions which hold that the latter's out-
come was not inevitable

If classic gun-armed coast defence ships never managed 

to alter the course of actual maritime conflicts, they cer-
tainly inspired further developments of the genre which 
played a major role in the creation of the big gun battleship, 
as well as contributing to the design process which spawned 
intermediate ideas like Germany's 'Panzerschiffe'. As out-
lined in Chapter 8, these vessels were difficult to classify 
when they were designed, 'armoured ship' being a mean-
ingless or euphemistic term to most foreign observers, lead-
ing to such hyperbole as their description by the British as 
'pocket battleships', a term which the Germans never used. 
Today, they are perhaps best described as armoured 
cruisers. In this connection, it is interesting to note that 
Britain continued this habit of not sharing the German view 
of their capital ships, Gneisenau  and  Scharnhorst  being de-
scribed as battleships by the Germans and battlecruisers by 
the British, who felt that their inferior armour and -
compared to most battleships - their inferior gunnery mer-
ited the description.

 

In at least one case, that of Sweden, coast defence battle-

ships and the rest of the network of coastal defence so 
painstakingly constructed in that country, posed an effec-
tive deterrent to much more powerful potential adversaries 
like Germany and the Soviet Union and as such influenced 
the course of greater events in northern Europe.

 

The demise of the battleship after the Second World War 

and the creation of wholly new military technologies, rang-
ing from the atom bomb to the guided missile, seemed to 
make a nonsense of the idea of coastal defence. (The same 
assumption was made by observers reflecting on many other 
military technologies, from armoured vehicles to artillery 
and conventional manned military aircraft.) Still, many 
countries chose to retain their coastal gunnery after 1945 
and, in time, a totally new coastal defence vessel in the fast

missile boat was created whose primary weapon had a far 
greater range than the torpedo boat with limited seakeeping 
which it replaced.

 

Almost a century and a half after the Monitor, the modern 

missile corvette is the true inheritor of the mantle once 
worn by the gun-armed coast defence ship. In designs such 
as the trimaran frigate and corvette concepts now being 
investigated by shipyards and, for example, the Ministry of 
Defence in Britain, the coast defence missile corvette is 
even leading the way towards wholly new hull forms. It is a 
fair bet that within the next generation, the trimaran hull 
form might take its place in several of the world's navies.

 

As such, one generic type of vessel - the coast defence 

ship - will have again shown that just as it can be renewed 
to cope with new threats, it can also be modernised in order 
to seize a technical lead, just as the turret ship Prince Albert

 

had done in the 1860s, inspiring a whole new range of ves-
sels which, as the 'Family Tree' of coast defence ships 
shows, led directly to the largest battleships. Thus has the 
coast defence ship earned its place in history.
