For
many people, the name Rolls-Royce still conjures up the idea of
“armoured car”, at least as much as visions of the urbane life
associated with what is claimed to be “the Best Car in the
World”. The reason is easy to find because not only did
Rolls-Royce armoured cars serve on many fronts as far apart as
South-West Africa and Russia from 1914 onwards in the First World
War, but in a recognizably similar form were employed in the British
and other armies throughout the inter-war years all over the world,
and again in action during the earlier years of the Second World War.
The
foundation of this story of successful longevity really lies in the
London-Edinburgh trials of the year 1911 when Rolls-Royce cars
established their reputation for high quality combined with strength
and reliability. After the outbreak of war, early reports from
Commander C. R. Samson's RNAS aeroplane and armoured car force at
Dunkirk confirmed that mechanically the best of his improvised
armoured cars were undoubtedly the RollsRoyces.
In
September 1914, all Rolls-Royce chassis in the works at Derby, or in
the hands of coachbuilders or agents, and some cars completed with
coachwork were requisitioned. These were all of the “Silver Ghost”
model which had been standardized since 19088. The engine was a
six-cylinder 7428-c.c. unit described as 40/50 h.p. and developing a
maximum of around 8o b.h.p. The gear-box was a four-speed type in
1914 cars although it is believed that a few earlier cars with the
three-speed gearbox may also have been among those converted to
armoured cars.
Design
of the turreted pattern RollsRoyce armoured car was commenced
about October 1914, following discussions as to how to provide
better protection than that offered by the early open top armoured
vehicles. A small committee was formed in the Admiralty Air
Department to consider this problem. Leading members were Squadron
Commander W. Briggs and Flight Commander T. G. Hetherington (both
of the R.N.A.S.) and they were assisted by Lord Wimborne and Mr N.
C. Macnamara. A rough design of car with a turret was worked out and
a model was made in three-ply wood. This involved some curved armour
plates and Mr Scott of William Beardmore and Co. evolved a method
of bending light armour plate.
After
the design was finalized, production went ahead and the first
three Rolls-Royce armoured cars of the turreted pattern were
delivered on 3 December 1914. The complement for the first RNAS
squadron of the Armoured Car Division - twelve armoured cars - was
completed during December and the squadron was sent to the East
Coast of England both for trials and to guard against invasion. In
service, heavier suspension was found to be necessary and new
springs, consisting of thirteen leaves at the front and fifteen
leaves at the rear, were fitted on these cars and standardized for
all later Rolls-Royce armoured cars. The new axle casings were also
changed for a heavier pattern.
A
total of six squadrons of Rolls-Royce armoured cars was completed by
the end of January 1915 but Maxim machine-guns had to be obtained
from ships of the Fleet to fully equip them all.
Training
went ahead quickly, and in March the first two squadrons were sent
on active service overseas - one to France (and later to Egypt) and
the other to German South-West Africa from whence in July a section
went on to East Africa. Early experience in action in France
suggested the need for a plate on the gun barrel to protect the open
mounting and this was fitted, on many cars later. In Africa the cars
won praise for their mechanical reliability (although conditions in
some areas precluded the use of the higher gears for days on end),
but the twin Rudge Whitworth rear wheels filled with Rubberine (a
puncture sealing substance) were often in urgent need of replacement.
In
April two further squadrons were sent to Gallipoli where, however,
only one major opportunity presented itself for armoured car action.
From
August 1915 onwards the Royal Naval Air Service Armoured Car
Division was broken up and most of the equipment was handed over to
the Army. Some Rolls-Royce armoured cars were at this time stripped
of their armour and converted into ambulances, light lorries or
tenders. Others remained in service in Light Armoured Motor
Batteries of the Army, including the cars in Egypt and Palestine and
the ones that took part in Colonel T. E. Lawrence's campaign.
Two
Rolls-Royce armoured cars were in Russia with Commander
Locker-Lampson's force (which remained a Royal Naval Air Service
detachment) until the Revolution in 1917 - one of these was claimed
to have done 53,000 miles over terrible roads or no roads at all
with only minor repairs.
The
Rolls-Royce 1914 Admiralty
turreted pattern armoured car needs little description: its basic
layout with a central driver's and fighting compartment topped by a
revolving turret and and open platform behind was used for other
types of British armoured cars right up to the Second World War. The
crew was normally three men - the driver sitting on the floor on a
cushion and, in action, the other two standing to serve the Vickers
machine-gun mounted in the turret. Space was limited inside the car,
however, and for this reason sometimes the crew was only two, in
which case the driver fed the machine-gun, when driving, with one
hand.
There
were a few modifications and variants of the basic type. One
experimental car had the turret removed and a 1-pdr. automatic gun
(“pom pom”) fitted on an open mounting. Minor modifications were also made on the cars
according to their own theatres of war. For example, T. E.
Lawrence's cars all had double wheels front and rear to cope with
the extremely rough desert terrain. They also removed the roof
plates so that the conditions inside would be made more bearable.
Other modifications were made for different fighting zones such as
the addition of an extra commander's cupola on the turret roof. For engaging and pulling away barbed wire entanglements,
some cars in France had a pivoted hook fitted at the front - this
idea apparently originated at Gallipoli, where Turkish trenches were
attacked in this way. Other than this no other major modifications were
made right up to 1920 when new plans were drawn up for a totally
improved armoured car. It turned out however that the so-called
improvement was almost identical to the old 1914 pattern save an
extra inch to the turret height, louvres on the hatches in front of
the radiotor plus the addition of disc wheels.
Some
Rolls-Royce armoured cars of this 1914
pattern (together with cars of the very similar 1920
pattern) remained in service for many years after the War -
notably with the Royal Tank Corps in India and with the Royal Air
Force Armoured Car Companies in Iraq. Some of the R.A.F. cars (somewhat
modernized) were still in active use at Habbaniya as late as 1941.
Colour schemes varied with the type of country in
which they were used. Normally service green was used in the United
Kingdom but green with brown and dark grey (or variations of this
theme) were used in war-time European theatres; and sand with or
without charcoal and black (or pale blue-grey) were used for desert
camouflage. Dazzle camouflage was also used in fairly regular
patterns. The colours consisted of yellow ochre, red-brown, blue and
dark green (similar to the early tanks of this period). The tyres
are light grey, the colour of natural rubber.
