TheRenault R35,an abbreviation ofChar léger Modèle 1935 RorR 35,was a French lightinfantry tankof theSecond World War.

Designed from 1933 onwards and produced from 1936, the type was intended as an infantry supportlight tank,equipping autonomous tank battalions, that would be allocated to individual infantry divisions to assist them in executing offensive operations. To this end it was relatively well-armoured but slow and lacking a good antitank-capacity, fitted with a short 37 mm gun. At the outbreak of the war, the antitank-role was more emphasized leading to the development and eventual production from April 1940 of a subtype with a more powerful longer gun, theRenault R40.It was planned to shift new production capacity to the manufacture of other, faster, types, but due to the defeat of France the R35/40 remained the most numerous French tank of the war, about 1685 vehicles having been produced by June 1940. At that moment it had also been exported toPoland,Romania,TurkeyandYugoslavia.For the remainder of the war Germany and its allies would use captured vehicles, some of them rebuilt intotank destroyers.

Development

The development plan of 1926 foresaw the introduction of achar d'accompagnement,a cheap mass-produced light tank to replace theRenault FTofWorld War Ivintage, to make it possible for the standard infantry divisions to executecombined armsinfiltration tactics,seen as the only viable method of modern offensive warfare left for non-motorised units. The French army did not have the means to motorise more than a few select divisions. In 1930 this plan was replaced by a new one, giving more precise specifications. The first tank to be developed to fulfil its requirements, theChar D1,proved to be neither cheap nor particularly light. In 1933,Hotchkissoffered an alternative solution, the laterHotchkiss H35.For political reasons this proposal was turned into thePlan 1933and the whole of French industry was in August 1933 invited to propose possible designs. Fourteen companies responded (among whichDelaunay-Belleville) and five submitted a prototype:Hotchkissitself, theCompagnie Général de Construction des Locomotives,APX,FCMand of course France's prime tank producer:Renault.Fearing that his rival Hotchkiss might well replace him as such,Louis Renaulthurried to finish a vehicle; construction was soon in such an advanced stage that the changes in specification issued on 21 June 1934, to increasearmourthickness from 30 to 40 mm, could not be implemented. On 20 December 1934 Renault was the first to deliver a prototype, with the project name ofRenault ZM,to theCommission de Vincennes.

In the spring of 1935 this vehicle was refitted with heavier armour and a standard APX turret, attached by theAtelier de Rueilbetween 18 and 25 April. The prototype was still being tested when international tensions increased due toGerman re-armament.This prompted an urgent demand for swifter modernisation of the French tank fleet. The ZM was to be put into production immediately. On 29 April 1935 an order of 300 was made, even before the final model could be finished, at a price of 190,000French francper hull (unarmed, without the engine and turret, the overall export price was ca. 1,400,000 francs in 1939,that is ca. 32,000 dollars by 1939 standards).The first series production vehicle was delivered on 4 June 1936 and had to be extensively tested again as it was different from the prototype.

Description

Renault R35: the hatch at the back of the turret is clearly visible

To save time, Renault based the suspension and running gear on that of theAMR 35that was designed for the cavalry. It had five wheels at each side, fitted with horizontal rubber-cylinder springs, like theAMC 35.

The hull, with a length of 4.02 m, consisted of three cast modules, with a maximum armour thickness of 43 millimetres, that were bolted together. Total weight was 10.6 metric tonnes (9.8 tonnes without fuel and ammunition). The bottom module carried on each side an independently sprung front wheel, two bogies and the driving sprocket at the extreme front. The final drive and differentials were housed at the right in the nose module. It was steered through a Cletrac differential with five gears and by engaging the brakes. The driver was seated somewhat to the left and had two hatches. The Renault V-4 85 hp engine was to the right in the short rear with theself sealing166 litre fuel tank at its left. It rendered a road speed of 20 km/h and a range of 130 km. Cross-country speed did not exceed 14 km/h and the fuel consumption totaled 212 litre/100 km. From 1940 onward they were fitted with AMX tails to help in trench crossing.

The cast APX hexagonal turret had a 30 mm thick domed rotatable cupola with vertical vision slits (the highest point of 2.13 m) and had to be either hand cranked or moved about by the weight of the commander, the only other crew member. There was sometimes unofficially a seat installed for him but he most often stood. The rear of the turret had a hatch that hinged down that could be used as a seat to improve observation. The earliest vehicles were fitted with the APX-R turret (with the L713 sight) mounting the shortPuteaux37 mm L/21 SA18gun (the first batches were removed from Renault FT tanks which were then rebuilt as utility vehicles) and the 7.5 mmChâtelleraultfortress machine gun. The cannon had a very poor armour penetration: only 12 mm at 500 metres. Afterwards the APX turret with the same cannon but the improved L739 sight and the standard Châtellerault 7.5 mm MAC31Reibel machine gunwas used because of delivery delays of the original weapon. There were also so many delays in the production of the turrets that after the first 380 hulls had been produced in 1936 and only 37 could be fitted with a turret, production was slowed down to 200 annually. The 7.5 mmmachine gun's spent cartridges (from a total of 2,400) went down a chute through a hole in the floor. The tank carried 42armour piercingand 58high explosiverounds.

The R 35 at first had no radio, except for the second battalion of the507e Régiment de Chars de Combat(ofCharles de Gaulle), but the R 40 had the ER 54 installed. However, this added to the already heavy task load of the commander, who also acted as gunner and loader.

Renault R40 and projects

Main article:Renault R40

In 1937 it had become obvious the original suspension system was unreliable and ineffective. After many trials it was replaced in the 1940 production run, after the 1540 vehicles had been built with the original design, by an AMX system using twelve wheels fitted with six vertical springs (AMX was the new name of the military division of Renault nationalised on 2 December 1936). About the same time the radio and a much more powerful gun were introduced. The long-barrelled L/35 37 mm SA38 in the adapted cast APX-R1 turret (with L767 sight) gave it an effective anti-tank capacity: 40 mm at 500 metres. The new combination was named theChar léger modèle 1935 R modifié 1939but is more commonly known as the Renault R40. It was delivered in time to equip one battalion of thePolish 10th Armoured Cavalry Brigadeof the Polish Army in France and the last two French tank battalions to be formed. It was intended to fit the R 40 with the welded FCM turret in the second half of 1940, while refitting all existing R 35s with the longer SA 38 gun and bringing R 40 production levels up to 120 per month for the duration of the war. From January 1940, the vehicles of light tank unit commanders were gradually uparmed with the longer gun; but as absolute priority was given to tanks serving in armoured divisions, which were of the Hotchkiss type, of the 273 platoon, company and battalion commanders eligible in Renault units, only a few if any received this "R 39". The only official possible exception to the rule that Hotchkiss tanks had to be modified first was made on 12 February 1940 when it was ordered to replace the turrets of 24 Infantry tanks, without specifying the type, present in depot or driver schools in order to obtain older turrets to be fitted on R 35 export vehicles.In the same period a crash programme was executed to produce 200,000 armour piercing rounds per month for the shorter gun, as there had been only minimal stocks of this ammunition type.

Several projects were based on the R 35 such as a number offascinecarriers: these had frames or other contraptions mounted over the hull or turret with a fascine in them that could be dropped to fill trenches.

Operational history

The R35 was intended to replace the Renault FT as standard light infantry tank from the summer of 1936, but even by May 1940 not enough conscripts had been retrained and therefore eight battalions of the older tank had to be kept operational. On 1 September 1939, at the outbreak of war, 975 vehicles had been delivered out of 1070 produced; 765 were fielded by tank battalions in France, 49 used for drive training, 33 were in depot and 45 present in the colonies. Of a total order for 2,300 at least 1,601 had been produced until 1 June 1940 — the numbers for that month are lacking — of which 245 had been exported: to Poland (50), Turkey (100; two batches of fifty each in February and March 1940),Romania (41 from an order for 200), and Yugoslavia (54). It is likely that the tanks exported to Yugoslavia (in April 1940) are not included under the 1,601 total and that overall production was 1,685; serial numbers known to be actually used indicate a production of at least 1670 vehicles.

Poland

As the threat of war became apparent and the production rate of Polish7TPtank was insufficient, it was decided to buy vehicles abroad. Poles were most interested in FrenchSOMUA S35tanks, but the proposal was refused by the French government. In 1938 the Polish Army bought one (according to other sources, two or three) R35 tank for testing. After a series of tests it was found that the design was disappointing: the engine was overheating, the suspension was tough, and armament insufficient. In April 1939 it was finally decided to buy a hundred R35 tanks as an emergency measure. The first shipment of fifty (other sources lower the number to 49) arrived in Poland in July 1939, along with threeHotchkiss H35tanks bought for testing. In August they were mostly put into service with theŁuck-based 12th Armoured Battalion. At the beginning of theInvasion of Poland45 (or 46) tanks formed the core of the newly created 21st Light Tank Battalion that was part of the general reserve of the Commander in Chief. The unit was to defend theRomanian Bridgehead,but was divided after the Soviet invasion of Poland of 17 September. Late September the unit was withdrawn to defend theRomanian Bridgehead.Subsequently, 34 tanks were withdrawn toRomania.Six tanks were attached to the10th Motorized Cavalry Brigadein Stanisławów (todayIvano-Frankivsk); they forced their way through Kolomyia and three vehicles crossed theHungarianborder. The remaining tanks - four R35s and threeH35s- were put into service with the improvisedDubnoOperational Groupand took part in the battles of Krasne on 19 September (with theSoviets) and Kamionka Strumiłowa (with theGermans), during which all were destroyed. The second shipment of R35s did not reach Poland prior to the outbreak of World War II.They were diverted by the French toSyria.

Hungary

A smaller Polish force retreated to Hungary from the German and Soviet troops occupying Poland. In addition to thirty tankettes (TK-3 and TKS), this mixed formation also had three R35s. These vehicles were by Hungary used for training in tank driving and machine gun handling drills. By the end of the war, they were worn out due to the lack of spare parts; there is no trace of them after 1944.

As part of a rearmament program of the late 1930s,Romaniasought to obtain a license for the local manufacture of two hundred French Renault R35 infantry tanks. By early 1938, negotiations for establishing a factory for the production of R35 tanks had reached an advanced state. By this time France's own demands for rearmament prohibited further development, however. In August and September 1939, as a stopgap measure, forty-one R35s were supplied to the Royal Romanian Army. These tanks served as the principal tank of the newly formed 2nd Armoured Regiment. At the end of September 1939, an additional thirty-four brand new R35s passed into Romanian hands when the Polish 21st Light Tank Battalion (Batalion Czołgów Lekkich,or BCL) chose internment over capture following the German conquest of Poland and fled over the Romanian border. With seventy-five tanks on strength, the 2nd Armoured Regiment expanded into two battalions.

After theBattle of Stalingrad,the Romanians decided that the R 35s required significant improvement of their anti-tank capacity. At first, the turret of an R 35 of the 2nd Tank Regiment of the 1st Tank Division was swapped for the turret of a captured SovietT-26.Ultimately, at the beginning of 1943, it was decided to keep the thicker armor of the French turret. Thus, the 45 mm gun of the T-26 was adopted as a replacement for the original 37 mm gun. The Soviet gun was attached to the French turret with the help of an extension which contained the recoil mechanism of the 45 mm piece. The downside to this was that, following these modifications, there was no longer enough space in the turret to keep the coaxial machine gun, which was thus removed. A Romanian-produced 47 mm Schneider gun was also proposed. The upgraded tanks were adopted astank destroyersunder the designationVânătorul de care R35(VDC 35; meaning "R35 tank hunter" ), with thirty R35s converted until June 1944 by the Leonida factory in Bucharest. The Soviet45 mm gunswere taken from captured T-26 and BT-7 tanks. They were refurbished at theArmy ArsenalinTârgoviștewhile the new gun mounts containing the recoil mechanism were made at the Concordia Works inPloiești.These vehicles served until the end of the war. A significant amount of the original French-made parts, from both the original and converted R35 tanks, was replaced by Romanian-produced spares in 1941–1942. Romanian factories produced drivesprockets,drive shafts,tracks, new metal-rimmed road wheels andcylinder heads.The wheels were designed locally to be ten times more durable. Added to these were the gun mounts for the 45 mm guns, added as turret extensions, which contained the recoil mechanism. Thus, the Romanian-converted R35 had significant Romanian-manufactured parts in its hull, transmission and turret.

There were sixty R35 tanks in the Romanian inventory on 19 July 1944, thirty of which had been rearmed with 45 mm guns.

The only surviving part of a VDC R35 is a turret owned by a private collector from Slovakia.

France

On 10 May 1940,on the eve of the German invasion,in mainland France the R 35 equipped 21 battalions, each fielding 45 vehicles. This gave 945 R 35/R 40 tanks in the French front line units. Of these, 900 were originally allocated at Army level inGroupements de Bataillons de Charsconsisting of several battalions:

These pure tank units had no organic infantry or artillery component and thus had to cooperate with infantry divisions. However, 135 R35s (2, 24 and the new 44 BCC) were allocated on 15 May to the provisional4th DCR(Division Cuirassée). Two more new battalions, the 40th and 48thBataillion de Chars de Combat,though still not having completed training, were used to reinforce2nd DCR,the first equipped with 15 R35s and 30 R40s, the second with 16 R35s and 29 R40s bringing the total organic strength to 1035. In addition the 1st and 2nd Tank Battalion of thePolish 10th Armoured Cavalry Brigade,at first training with Renault FTs, were equipped with 17 R35s and about 24 R40s in late May; in June the R40s had been given back but replaced by 28 new ones. At the same time 1, 6, 25, 34 and 39 BCC were used to reconstitute 1DCR, 10 BCC reinforced 3DCR and 25 BCC was reconstituted with 21 R35s and 24 (ex-Polish) R40s. As about 300 tanks from the materiel reserve were issued to these units as well, around 800 of the 1440 available R35s ended up in armoured divisions after all.

French colonies

Two R35 battalions (63 and 68 BCC) with 45 and 50 tanks respectively were inSyria,a Frenchmandate territory,and 30 were inMorocco,26 serving with 62 BCC and four in depot. The tanks in Syria would fight during the allied invasion of that mandate territory in 1941 and then partly be taken over by theFree French1e CCC,those in North Africa duringOperation Torchin November 1942.

Germany

The majority (843) of R35s fell into German hands; 131 were used as such asPanzerkampfwagen 35R 731 (f),issued to panzer units and mainly used for security duties or driver training, or used on armoured trains; most were later rebuilt as artillery tractors and ammunition carriers after removing the turret.

A considerable number, 174 according to some sources,were converted into a 47 mmtank destroyerto replace thePanzerjäger I:the4,7 cm PaK(t) auf Panzerkampfwagen 35R(f) ohne Turm.The tank destroyer version had the turret replaced with an armoured superstructure mounting a47mm kanon P.U.V. vz. 36 (Škoda A6)anti-tank gun. The vehicles were converted by Alkett between May and October 1941 to try and make an equivalent vehicle to the Panzerjäger I. The result was not as successful as the Panzerjäger I, mainly due to the slow speed of the R 35 and the overloaded chassis. A few were deployed inOperation Barbarossa,most were deployed in occupied territories, such as theChannel Islands,The Netherlands (with Pz.Jg.Abt.657, part of Pz Kompanie 224) and France.They fought in the battles for Normandy withSchnelle Brigade 30in 1944 (five attached to the 3rd company,Schnelle Abteilung 517), and aroundArnhemwith Pz.Jg.Abt. 657. Other possible users include 346 Inf. Div. in Normandy and 59th Inf. Div who fought the 101st Airborne during Operation Market Garden.

Some of the turrets removed from the tanks were used ondefensive fighting positionsknown as "Tobruks". This gave the Tobruk enhanced firepower and the gunner protection from shrapnel and small arms.

Fourteen R 35 tanks, used to train tank drivers, equipped the100. Panzer-Ersatz-Bataillon(100th Panzer Replacement Battalion) in theGerman Seventh Armyin 1944. On 6 June 1944, they were among the firstArmee-Reserveunits sent into combat nearSainte-Mère-Égliseto oppose theAmerican airborne landings in Normandy.Supporting a counterattack by the 1057th Grenadier Regiment, R35s penetrated the command post of the U.S. 1st Battalion505th Parachute Infantry Regimentbefore being destroyed bybazookafire.

Italy

TheRoyal Italian Armyreceived 124 R35s with which the4th Tank Infantry Regimentformed two battalions. The two battalions were assigned to the131st Tank Infantry Regiment,which was deployed in January 1942 toSicily.There, the regiment's CII Tank Battalion R35 was assigned to the XII Army Corps defending the island's West, while the regimental command and CI Tank Battalion R35 were assigned to the XVI Army Corps defending the island's East. The regiment used some of its R35s indefenceofGelaonSicilyagainstUS Rangers.5th Battalion, East Yorkshire Regimentwas attacked by five R35s as it advanced towardsSortino;four were quickly knocked out but the fifth drove right through the battalion and carried on until it was knocked out by a105 mm self-propelled gunnearFloridia.

Other forces during the Second World War

Some of the tanks that Germany captured were given or sold to Germany's allies:Bulgariareceived about forty.

Three Polish vehicles in late 1939 found their way toHungary.

During the Syria-Lebanon Campaign, the Australian2/6th Cavalry Commando Regiment's 'A' Squadron used four R35s that had been captured from the Vichy French.

Switzerland took over twelve R 35s that had fled from France.

After the German victory over Yugoslavia in 1941, theIndependent State of Croatiatook over some R35s that had not been destroyed when fighting11. Panzerdivisionon 13 and 14 April.

Syria and Lebanon

The R 35 saw combat in Syrian hands when five R 35s took part in an unsuccessfulSyrian Armyattack on theJewishkibbutzDegania Alefin theGalileeon 20 May 1948. The kibbutz defenders, armed with a 20 mm anti-tank gun andMolotov cocktails,managed to knock out three R 35s, causing the remaining forces to retreat.One of the disabled R 35s remains near the kibbutz today as a memorial of the1947–1949 Palestine war.A 1991IDFprobe proved that this R35 had been knocked out by aPIATround.

The Lebanese Army also incorporated a number of R 35s. Some of the Lebanese vehicles had been rebuilt with a British 40 mmOrdnance QF 2-poundergun, seeing action in the1958 Lebanon crisis.

Postwar France

Some R 35s served after the war in the Gendarmerie, as "R 39s" refitted with SA 38 guns. They were phased out from 1951 in favour of theSherman tank.
