British Nomenclature
The British received far more M4 medium tanks, 17,181
(roughly 34% of all M4s produced), than any other Allied nation. The British
practice of naming American tanks after American Civil War generals was continued,
giving it the name Sherman after Union General William Tecumseh Sherman. The US
later adopted the name and the practice of naming tanks after generals and
initially used the full name "General Sherman".
In the British naming system, the major variants were
identified by Mark numbers, the M4 being "Sherman I", the M4A1
"Sherman II" and so on. Letters after the mark number denoted
modifications to the base model: "A" for the 76 mm L/55 gun instead
of the 75mm, "B" for the 105 mm M4 L/22.5 howitzer, "C" for
the British 76.2 mm QF 17-pounder gun, and "Y" for the later
wider-tracked Horizontal Volute Spring Suspension (HVSS) type suspension. Gun
and suspension letters were used in combination, e.g. Sherman IBY. However, not
every combination appeared, e.g. no production 75mm Shermans were built with
HVSS and hence no HVSS 17pdr conversions - which would have been designated
"CY" - therefore existed. HVSS Shermans were only fitted with 76mm M1
guns or 105mm M4 howitzers, AY and BY respectively in British service.

Allied Variants
Conversions and modifications of the M4 by their foreign
users included the British-Commonwealth Firefly with the potent British QF 17
pounder (76.2 mm) anti-tank gun; Adder, Salamander, Crocodile, and Badger
flame-throwing Shermans; Kangaroo armored personnel carrier; Armored recovery
vehicles (ARV); artillery tractors, and the specialist military engineering
vehicles of "Hobart's Funnies" designed specifically for Operation
Overlord ("D-Day") and the Battle of Normandy. In 1945, the 1st
Battalion Coldstream Guards at the Rhine fitted Sherman turrets with two
"60 lb" RP-3 air-to-ground rockets on rails to create the Sherman
Tulip. Canada created a prototype anti-aircraft vehicle with four 20 mm Polsten
cannons mounted in a turret on Canadian-made M4A1 hull, which was called Skink.
The Soviets reportedly replaced the US 75 mm gun on some M4A2s with the 76.2mm
F-34 gun of the T-34 medium tank to create the M4M; they discontinued the
practice when assured of US ammunition supply. For the Normandy landings, the
British developed special and specific deep wading kits for Shermans I/II, III
and V. US forces in the Pacific suffered many drowned M4s by not having such
kits early in the island landing campaigns, and they were rapidly copied for
later landings.
Conversions
A number of Sherman tanks were
converted to carry different armament or fill different roles than those for
which the tank was originally manufactured. Among these were:
Tank AA, 20 mm Quad, Skink: Canadian
prototype anti-aircraft vehicle with four 20 mm Polsten cannon mounted in
a turret on a Grizzly hull (tank made in Canada, not Lend-Leased).
Sherman Duplex Drive (DD):
British-developed swimming gear fitted to British, Canadian, and US Shermans
for the Normandy landings.
Sherman 17pdr aka "Firefly":
British Sherman I or V re-armed with QF 17 pounder (76.2 mm) anti-tank gun
with C added to designation (as in Sherman IC or VC). A few Sherman IIIC
are believed to have existed, issued to units equipped with standard Sherman
III for mechanical commonality: Aberdeen Proving Ground in the USA has one.
Post-war the "Firefly" name is commonly used to refer to these
vehicles, but it was not an official name and not commonly used during the war.
Sherman Tulip: British Sherman with two
3-inch ("60lb") RP-3 rockets on rails added to the turret. Used by
the 1st Coldstream Guards at the Rhine in 1945.
RMASG "Control Tank": Sherman
V tanks allocated to the Royal Marines Armoured Support Group for the D-Day
landings were fitted with a dial sight in a protruding square cover on the top
right of the turret. This permitted them to be used accurately in the indirect
fire role as self-propelled artillery, initially from the decks of landing
craft but later also ashore. Direct fire sights were retained. These tanks can
be identified in photos by the 360-degree compass bearing markings around the
turret.
Combat Engineering Vehicles
British developments for Shermans
were extensive and included the fascine carrier (used by 79th Armoured
Division), "Crib", "Twaby Ark", "Octopus",
Sherman Bridgelayer:
"Plymouth" carrying Bailey bridge
Sherman AVRE with Small Box Girder bridge
Sherman CIRD: fitted with "Canadian
Indestructible Roller Device" landmine exploder
Sherman Crab: British Sherman with mine
flail, one of a long line of flail devices
Recovery Vehicles
Sherman ARV I and Sherman ARV II –
British armored recovery vehicle conversions of Sherman I, III and V. It was
British policy to have ARVs using the same mechanical parts as the gun tanks
they supported wherever possible. ARV I was a simple turretless towing vehicle
with light jib while ARV II had much more sophisticated recovery and repair
equipment, a raised box-like superstructure and heavier jib. It was considered
superior to the US M32 ARV, very few of which were used by British units.
Beach Armoured Recovery Vehicle (BARV)
– British conversion of Sherman III with large boat-shaped superstructure that
was capable of deep wading near the shore. A simple push/pull ARV that served
until replaced by Centurion BARV in the mid-1960s. The diesel-engined Sherman
III was considered less likely to be affected by the wet environment than
petrol-engined versions.
Artillery
Sherman Gun Tractor – British field conversion in Italy by removing
turrets from M4A2 Sherman III tanks to tow 17 pdr AT gun and carry crew with
ammunition. Some of the removed 75mm M3 guns may have been used for the
Churchill NA75 field conversions unique to the Italian campaign.
Sherman Observation Post – an armored mobile post for controlling
artillery. The 75 mm gun was removed (with a dummy barrel fitted outside) to
give room for map tables in the turret. Three radio sets were fitted (two
Number 19 and a Number 18). Two more – both Number 38 – were carried for
portable use outside the tank.
Personnel Carriers
Sherman Kangaroo – Canadian Sherman converted into "Kangaroo"
armored personnel carrier
Flame Tanks
Sherman Adder – A conversion kit to equip Sherman tanks, used in
India on Sherman III and Sherman V
Sherman Badger – Canada's replacement of its Ram Badger, the
Sherman Badger was a turretless M4A2 HVSS Sherman with Wasp IIC flamethrower in
place of hull machine gun, developed sometime from 1945 to 1949. The 150 imp
gal (680 L) at 250 psi (17 bar) was effective to 125 yd (114 m), with elevation
of +30 to −10 degrees and traverse of 30 degrees left and 23 degrees right.
This inspired the US T68.
Service History
United Kingdom
The British Empire received 17,184
Sherman tanks from the USA under Lend-Lease, roughly 78% of all American
Shermans provided worldwide under this program. This includes Sherman tanks
used by all members of the British Dominions and Empire and those Allies who
were equipped by the UK, such as the Polish Armed Forces in the West. The first
M4A1 Sherman II received by the UK was equipped with two driver-operated fixed
mount machine-guns in the hull front and carried the shorter M2 75mm tank gun
with a counterweight. The two extra hull machine-guns were a standard feature
of very early Shermans, carried over from the previous M3 Medium (Lee/Grant)
tank, and were one of the first elements to be discarded from the original
plan. Bovington Tank Museum has an example of this build-standard, the very
first Sherman tank supplied to the UK under Lend-Lease and named
"Michael". The British became the primary users of the M4A4 Sherman
V, which they found to be far more reliable than did the few US users (mainly
for testing within the continental USA). M4 Sherman I, M4A1 Sherman II and M4A2
Sherman III were also used in (roughly) that order of importance. Free Polish
and Czechoslovak government-in-exile armored units supported and equipped by
the British had M4A1s, M4A2s and some M4A4s.
Some Shermans in British service
were also converted to specialist-type combat engineering vehicles. The Sherman
Crab was the main conversion, which was designed to be used for clearing
minefields in northwestern Europe and Italy. The Beach Armoured Recovery
Vehicle was a waterproofed armored recovery vehicle produced in small numbers
and used only in support of beach-landings to pull drowned tanks and vehicles
from the water and to push off stuck or beached landing-craft.
North Africa
The first Shermans to see battle in
World War II were M4A1s (Sherman IIs) with the British Eighth Army at the
Second Battle of El Alamein in October 1942. The tanks had been supplied in a
hurry from the US, which had removed them from their own army units. They were
then hastily modified to meet British military requirements and for desert and
hot-weather conditions, such as the addition of sand shields over the tracks.
Over 250 of these US-supplied Shermans, which were divided among 12 regiments,
participated in the battle. They formed the so-called "heavy
squadrons" (16 tanks in each) of one brigade in each division of X Corps
and some other squadrons of the other units taking part in the battle, with the
other heavy squadrons still being equipped with M3 Lee/Grant tanks and light
squadrons possessing M3 Stuart light tanks and Crusader cruiser tanks. The
British Shermans were able to tackle enemy rearguard units and defending troops
by using high-explosive (HE) shells which were fired indirectly at them whilst
the German 5 cm Pak 38 anti-tank gun was only effective against the Sherman if
it could engage it from the more-vulnerable sides. More of the British armored
units in North Africa were converted to increasingly-larger quantities of
Shermans over time from their successful outcome at El Alamein, including the
addition of Sherman IIIs (M4A2s) aside from the previous Sherman II, although
the infantry tank units retained use of their Churchill tanks.
Italy
The British forces in Italy did not
use their standard cruiser tanks (such as the Crusader). Instead, in their
place, they used Shermans and turretless and regular gun-tank Stuart tanks to
equip their reconnaissance troops. The other tank of the campaign was the
Churchill tank (early models carried a 6-pdr tank gun; later models had a 75mm
main gun), with such equipped tank units being bolstered with Shermans. In
general, the Shermans acted in the infantry support role in difficult
(mountainous and hilly) terrain against fixed-type German defenses and
fortifications. At the end of 1944, 76mm-, 105mm- (howitzer) and 17-pdr-armed
Shermans began to be fielded by the British troops as they came up against the
German-built and strongly-defended Gothic Line.
Northwest Europe
British and Commonwealth use in
Europe was comprehensive. The Sherman replaced the M3 Grant and Lee tanks and
the Ram Tank in Canadian service and was in the majority by 1944 – the other
main late-war tanks being the Churchill and Cromwell cruiser tank. The Cromwell
was used largely in the reconnaissance role. The slower, more heavily armored
Churchills were used in the infantry support Tank Brigades.
The Sherman 17pdr variant was
converted mostly from the M4 Sherman I and M4A4 Sherman V, with possibly a few
Sherman III, and was used both in Sherman and Cromwell-equipped units to add
extra anti-tank capability. The VC was necessary as the intended supplement
(the 17 pdr development of the Cromwell was produced in insufficient numbers whilst
the production of the VC was much greater). A 1944-pattern British armored
squadron (equivalent to a US company) had one 17pdr Sherman per troop (platoon)
of four Shermans. The 17pdr Sherman was retained in Cromwell units until the
introduction of the Comet, which carried the 77mm HV, a shortened derivative of
the OQF 17 pounder firing the 17 pounder shell from the cartridge of the
obsolete 3-inch 20cwt AA gun for less recoil but with slightly less armor
penetration.
By the end of the war, 50% of the Shermans
in British service were VCs or ICs. With the end of the war, and with superior
tanks entering service, the UK returned its Shermans to reduce its Lend-Lease
payments. However, the US did not really want the 17pdr conversions returned
and many found their way from British stocks into other armies post-war, where
they served until the 1960s in many cases (e.g. Argentine Repotenciado upgrade
of IC and VC fitted with French 105mm gun and diesel engine).
India
In the Indian Army tradition,
formations included British regiments alongside Indian Army units. (The Army of
India consisted of both the Indian Army and the British Army in India between 1903 and 1947.) As well
as some Indian units receiving Shermans, the 116th Regiment Royal Armoured
Corps (converted from the 9th Battalion Gordon Highlanders) part of 255th
Brigade was equipped with Shermans. As part of the 255th, they were involved in
January and February 1945 in Burma in action near Meiktila and Mandalay. The
actions were predominantly in support of infantry with few enemy tanks
encountered. After that, they were part of mobile columns that moved to retake
Rangoon.
New Zealand
The 4th New Zealand Armoured
Brigade operated approximately 150 M4A2 Sherman tanks from late 1942 until the
end of the war. The 4th Brigade formed part of the New Zealand 2nd Division and
was converted from an infantry brigade. The 4th Armoured Brigade saw action
during the Italian Campaign.
Australia
Although the Australian Army
received 757 M3 Lee/Grants in 1942, it only received three Sherman tanks. These
three tanks were supplied by the UK and were only used for trials purposes.
When the Australian Cruiser tank program was cancelled in 1943, after US
authorities promised M4 Mediums would be available in any quantity required by
Australia. A proposal was made to replace the entire order of 775 Australian
Cruiser tanks with 310 Sherman tanks; however, this proposal was not acted on.
Early in 1944 Australian Army was requested by War Office to undertake trials
of Churchill and Sherman tanks in "New Guinea conditions". Trials
were conducted in the jungle terrain of New Guinea using British Churchill Mk
IV, Mk V and Mk VII Infantry tanks and American Sherman M4A1 and M4A2 Medium
tanks, and included armament tests involving firing 75mm and 95mm main guns on
a Japanese style bunker constructed from coconut logs. It was considered by
those trials results that the Churchill was preferable to the Sherman for
operations in jungle.
Australia's first Sherman, an M4A2,
arrived in Australia in 1943 with a further two M4s (sometimes mis-labelled as
M4A1s) arriving for tropical trials in New Guinea in 1944. The tanks were
manned by crews drawn from the Australian 4th Armoured Brigade. The results of
these trials showed that the British Churchill tank was better suited to jungle
warfare's low-speed infantry support than the Sherman. As a result, the
Australian Government ordered 510 Churchills, of which 51 were delivered before
the order was cancelled at the end of the war, and did not order any further
Shermans. Following the war, the three trials tanks were placed on display at
Australian Army bases and one was later destroyed after being used as a tank
target.
Canada
The United States officially did
not list Canada as a Lend-Lease recipient, but did create the 1941 Joint
Defense Production Committee with Canada so that "each country should
provide the other with the defense articles which it is best able to
produce" and American Locomotive Company enabled its Canadian subsidiary,
the Montreal Locomotive Works, to build M4A1 variants in Canada. Canada
received four Shermans under Lend-Lease; the mechanism of this is not fully
understood. The MLW built 188 Shermans called the Grizzly I cruiser in Canadian
service, which were restricted to training. As there was sufficient production
capacity in the US, the MLW investment in Ram and Sherman tank production was
turned to building of the Sexton self-propelled guns which used the 25pdr
gun-howitzer on M3 or M4 chassis. In European combat, the Canadian Army used
American-built Shermans supplied by the UK. These were armed with 75 mm, 105 mm
and 17-pounder guns.
China
Chinese forces based in British
India received 100 M4A4 Shermans from British stocks and used them to great
effect against considerably-inferior Japanese tanks and their infantry in the
subsequent offensives, such as in Battle of Northern Burma and Western Yunnan,
between 1943 and 1944. After the war, some vehicles remaining in India went to
the British, with several others put to use by the Nationalist Chinese
(Kuomintang) against Chinese communist (CCP) forces in the Chinese Civil War
until the KMT's defeat in 1949.
Soviet Union
The M4A2s used by the Red Army were
considered to be much-less prone to blow up due to ammunition detonation than their
T-34/76 but had a higher tendency to overturn in road accidents and collisions
or because of rough terrain due to their much-higher center of gravity.
Under Lend-Lease, 4,102 M4A2 medium
tanks were sent to the Soviet Union. Of these, 2,007 were equipped with the
original 75 mm main gun, with 2,095 mounting the more-capable 76 mm tank gun.
The total number of Sherman tanks sent to the U.S.S.R. under Lend-Lease
represented 18.6% of all Lend-Lease Shermans.
The first 76mm-armed M4A2
diesel-fuel Shermans started to arrive in Soviet Union in the late summer of
1944. By 1945, some Red Army armored units were standardized to depend
primarily on them and not on their ubiquitous T-34. Such units include the 1st
Guards Mechanized Corps, the 3rd Guards Mechanized Corps, 6th Guards Tank Army
and the 9th Guards Mechanized Corps, amongst others. The Sherman was largely
held in good regard and viewed positively by many Soviet tank-crews which
operated it before, with compliments mainly given to its reliability, ease of
maintenance, generally good firepower (referring especially to the 76mm-gun
version) and decent armor protection, as well as an auxiliary power unit (APU)
to keep the tank's batteries charged without having to run the main engine for
the same purpose as the Soviets' own T-34 tank required.
Poland
Poland was not a recipient of
Lend-Lease aid directly from the United States, however, Polish forces also
used a wide variety of Shermans redirected from Lend-Lease shipments to the
British Empire. The Polish 1st Armoured Division entered the Battle of Normandy
mostly equipped with Sherman Vs (M4A4s) with 75 mm guns, and VC Shermans. The
reconnaissance battalion was equipped with Cromwells, as in British armored
divisions. (With the 10th Mounted Rifle Regiment.) After heavy losses closing
the Falaise Pocket and in the Dutch campaign, the division was re-equipped,
largely with Sherman IIA (M4A1 (W) 76 mm) models.
The Polish II Corps, fighting in
Italy, primarily used M4A2s (Sherman III) that had been used by the British
Army in Africa. However, some ICs and Sherman IB (M4(105 mm)) howitzer tanks
were also used.
Parts of the Polish First Army also
briefly used M4A2 (76 mm) borrowed from the Soviet armies after heavy losses in
the conquest of Danzig. After receiving replacements, the army was re-equipped
with T-34s.
France
The first use of Sherman tanks by a
French unit appears to have been with 1ère Compagnie Autonome de Chars de
Combat (1ère CACC), it was merged with the French Army Corps Reconnaissance
Group (GRCA), and was known as the "Free French Flying Column". It
was part of the British Eighth Army, and fought from El-Alamein to Tunisia. The
tank company was attached to "Force L (Leclerc)" and later became the
1st Company of the newly organized 501ème Régiment de Chars de Combat, 2ème
Division Blindée.
In 1943, the Free French Forces
decided to create their new army in North Africa, and had an agreement with the
Americans to be equipped with modern US weapons. France received 656 Sherman
tanks under Lend-Lease (274 M4A4s and 362 M4A2s, plus 20 remanufactured M4A2s),
being the third largest recipient of the Sherman. French armored divisions were
organized and equipped the same as the U.S. Army's "light" armored
division table of organization and equipment of 1943. Each division was
equipped with 165 Shermans. The French 2nd Armored Division (French: Division
Blindée, DB) entered the Battle of Normandy fully equipped with M4A2s. The 1ème
and 5ème DB, which entered southern France as part of the First French Army,
were equipped with a mixture of M4A2 and M4A4 medium tanks. M4A3(76) and
M4A3(75)W tanks were later received from U.S. Army stocks as replacements to
make up for losses in combat, and the French were also issued M4A3 (105)
Shermans; the 2ème DB received a few M4(105)s at the end of July 1944 while
still in the UK. The 3ème DB, which served as a training and reserve
organization for the three operational armored divisions, was equipped with
roughly 200 medium and light tanks. Of these, 120 were later turned in to the
US Army's Delta Base Section at Marseille for reissue. In the final weeks of
the War in Europe, French units also received supplies of M4A1(75)s,
remanufactured in the US before shipment overseas.
Brazil
Brazil received 53 Sherman tanks
under Lend-Lease in 1944, all equipped with the 75 mm gun. These tanks were not
used by the Brazilian Expeditionary Force in Italy during the war, but sent
directly to defend Brazil itself. In the early 1950s, another group of 30
Sherman tanks was delivered under the Military Assistance Program, bringing the
total number of Shermans to 83 tanks. The variants of these tanks consisted of
40 M4, 38 M4 with the Composite Hull, and 2 M4A1. The Brazilian Army used the
Shermans until 1979 when they were replaced by M41 tanks.
Czechoslovakia
While the Czechoslovak
government-in-exile did not receive Lend-lease equipment from the United
States, its 1st Czechoslovak Armoured Brigade was equipped and supplied by the
British Army. The Brigade's equipment during the siege of Dunkirk included 36
Sherman ICs in addition to Cromwell tanks, which constituted the primary
armored vehicle operated by the brigade. The 17pdr Shermans were, in May 1945,
exchanged for 22 Challenger cruiser tanks with which the brigade returned home.
In addition, one damaged Sherman I abandoned by an unknown unit was salvaged
from the battlefield by the brigade's repair shop and was later used as a
recovery vehicle. This vehicle returned with the brigade to Czechoslovakia.
South Africa
South African Shermans were used by
the 6th Armoured Division.
