France had fought World War I without a heavy tank. In July 1918, at the very end of that conflict, it began development of such a machine. Manufactured by FCM (Forges et Chantiers de la Méditerranée, Le Seyne, Toulon), the Char 2C was intended as a breakthrough tank or “Fortress Tank” (Char de forteresse), intended to lead the great Allied offensives that were planned for the spring of 1919. France planned to produce 300, but only 10 were ever built. This monster had a crew of 12, weighed some 152,100 pounds, and was powered by two Maybach or Daimler Benz 250-hp gasoline engines. It had a speed of 7.5 mph. The Char 2C had maximum 45mm armor and was armed with a turreted 75mm gun (later a 155mm) and four machine guns.
The Char 2C had a loaded weight of 69 tonnes, partly because of its armour - 45 mm at the front, 22 mm at the sides, but much of it just because of its huge size. The armour was among the thickest of World War I-era tanks, though by modern standards this would be considered thin. It is still easily the largest tank ever taken into production. With the tail fitted, the hull was over twelve metres long. Within its ample frame there was room for two fighting compartments. The first at the front, crowned by a three-man turret (the first in history) with a long 75 mm gun, and the second at the back, topped by a machine gun turret. Both turrets had stroboscopic cupolas. The three independent 8 mm machine gun positions at the front gave protection against infantry assault.
The Char 2C is the only super-heavy tank ever to attain operational status — a super-heavy tank is not simply a tank that is very heavy but one that is much heavier than regular tanks of its period. The next operational tank to weigh about the same would be the Tiger II heavy tank of World War II.
The fighting compartments were connected by the engine room. Each track was powered by its own 200 or 250 hp engine, via an electrical transmission. Top speed was 15 km/h. Seven fuel tanks, containing 1,260 litres, gave it a range of 150 kilometres.
To man the tank required a crew of twelve: driver, commander, gunner, loader, four machine gunners, mechanic, electrician, assistant-electrician/mechanic and a radio operator. Some sources report thirteen, probably due to pictures of the crews that included the company commander.
The ten tanks were part of several consecutive units, their organic strength at one time reduced to three. Their military value slowly decreased as more advanced tanks were developed throughout the 1920s and 1930s. By the end of the 1930s they were largely obsolete, because their slow speed and high profile made them vulnerable to advances in anti-tank guns.
Nevertheless, during the French mobilisation of 1939, all ten were activated and put into their own unit, the 51st Bataillon de Chars de Combat. For propaganda, each tank had been named after one of the ancient regions of France, numbers 90-99 named Poitou; Provence; Picardie; Alsace; Bretagne; Touraine; Anjou; Normandie; Berry; Champagne respectively. In 1939, the Normandie was renamed Lorraine. As their main value was in propaganda, the giants were carefully kept from harm and did not participate in the September 1939 attack on the Siegfried Line. They were used for numerous morale-boosting movies, climbing and crushing old French forts instead. To the public, they obtained the reputation of invincible super tanks, the imagined dimensions of which far surpassing the real ones.
Of course, the French commanders knew perfectly well this reputation was undeserved. When the German Panzerdivisionen in the execution of Operation Fall Rot ripped apart the French lines after 10 June 1940, the decision was made to prevent the capture of the famous equipment. It was to be sent to the south by rail transport. On 15 June the rail was blocked by a burning fuel train, so it became inevitable to destroy the tanks by detonating charges. Later Goebbels and Goering claimed the tanks were hit by German dive bombers. This propaganda lie was to be repeated by many sources. One tank, the Champagne, was nevertheless captured more or less intact and brought to Berlin to be exhibited as a war trophy. In 1948 this tank disappeared, causing many to speculate it still survives at the Russian Tank museum in Kubinka.
In 1926, the later Champagne was modified into the Char 2C bis, an experimental type with a 155 mm howitzer in a cast turret. New engines were fitted and the machine gun positions deleted. In this configuration the tank weighed perhaps 74 tons. The change was only temporary though, as the vehicle was brought back into its previous condition the very same year; the new turret was used in the Tunisian Mareth Line.
Between 15 November and 15 December 1939 the Lorraine, as the company command tank, was experimentally up-armoured at the Société des Aciéries d'Homecourt to make it immune to standard German antitank guns. The front armour was enhanced to 90 mm, the side to 65 mm. In this configuration, weighing about 75 tons, the Lorraine had at that time the thickest armour of any operational tank, and is probably still the heaviest operational tank ever
