The SturmpanzerwagenA7Vwas aheavy tankintroduced byGermanyin 1918 duringWorld War I.One hundred chassis were ordered in early 1917, ten to be finished as fighting vehicles with armoured bodies, and the remainder asÜberlandwagencargo carriers.[2]The number to be armoured was later increased to 20. They were used in action from March to October 1918, and were the only tanks produced by Germany in World War I to be used in combat, as well as being the first operational German Tank.[3]It was developed as a response to British tanks. Although the A7V is generally considered to be better designed compared to itscounterparts,it struggled to procure high production numbers due to its relative complexity and high cost.[4][5][6]
History[edit]
After the firstBritish tanksappeared on theWestern Front,in September 1916, the German War Ministry formed a committee, under the auspices of itsAllgemeines Kriegsdepartement, Abteilung 7 Verkehrswesen( "General War Department, Section 7, Transportation" ),[7]to investigate tank development.
The project to design and build the first German tank was placed under the direction ofJoseph Vollmer,one of Germany's foremost automobile designers. It was to weigh around 30 tons, be capable of crossing ditches up to 1.5 metres (4.9 ft) wide, have armament including a cannon at the front and rear as well as several machine-guns, and reach a top speed of at least 12 kilometres per hour (7.5 mph). The running gear was based on the AmericanHolt tractor,copied from examples loaned by theAustro-Hungarian Army.After initial plans were shared with the army in December 1916, the design was extended to be a universal chassis that could be used as a base for both a tank and unarmouredÜberlandwagen( "over-land vehicle" ) cargo carriers.
The first prototype was completed byDaimler-Motoren-Gesellschaftat Berlin-Marienfelde and tested on 30 April 1917. A wooden mockup of a final version was completed in May 1917 and demonstrated in Mainz with 10 tons of ballast to simulate the weight of the armor. During final design, the rear-facing cannon was removed and the number of machine-guns was increased to six. The first pre-production A7V was produced in September 1917, followed by the first production model in October 1917. The tanks were given to Assault Tank Units 1 and 2, founded on 20 September 1917, each with five officers and 109non-commissioned officersand soldiers.[8]
Naming[edit]
The tank's name was derived from that of its parent organization,Allgemeines Kriegsdepartement, Abteilung 7 (Verkehrswesen)(General War Department, Section 7, Transport). In German, the tank was calledSturmpanzerwagen(roughly "armoured assault vehicle" ).[citation needed]
Design[edit]
The A7V was 7.34 m (24 ft 1 in) long and 3 m (9 ft 10 in) wide, and the maximum height was 3.3 m (10 ft 10 in). The tank had 20 mm of steel plate at the sides, 30 mm at the front and 10 mm for the roof;[8]however, the steel was not hardenedarmour plate,which reduced its effectiveness. It was sufficient to stop machine-gun and rifle fire, but not larger calibre rounds.
The crew officially consisted of at least 17 soldiers and oneofficer:commander (officer, typically alieutenant), driver, mechanic, mechanic/signaller, 12 infantrymen (six machine gunners, six loaders), and two artillerymen (main gunner and loader). A7Vs often went into action with as many as 25 men on board.
Armament[edit]
The A7V was armed with six 7.92 mmMG08 machine gunsand a5.7 cm Maxim-Nordenfelt cannonmounted at the front. Some of these cannons were of British manufacture and had been captured in Belgium early in the war; others were captured in Russia in 1918 and appear to have included some Russian-made copies.
Some A7Vs originally were built with two forward-facing machine guns instead of a 57 mm gun. Most were converted to carry a 57 mm before entering service. Number 501,Gretchen,took part in the action at St. Quentin before her 57 mm was fitted.
Ammunition[edit]
The A7V carried between 40 and 60 cartridge belts for its machine guns, each of 250 rounds, giving it a total of 10,000 to 15,000 rounds. Officially, it carried 180 shells for the 57 mm gun, of which 90 werecanister,54 werearmor-piercing,and 36 werehigh-explosive;in practice, however, A7V crews stowed up to 300 57 mm rounds for combat.
Propulsion[edit]
Power came from two centrally mountedDaimler4-cylinder petrol engines delivering 75 kW (101 hp) each; the A7V carried 500 litres (110 imp gal; 130 US gal) of fuel. The top speed was about 15 km/h (9.3 mph) on roads and 5 km/h (3.1 mph) across country. The 24 wheel suspension was individually sprung – an advantage over the unsprung British tanks. The A7V'spower-to-weight ratiowas 5.1 kW/ton (6.8 hp/ton), it could cross trenches up to 2.1 m (6 ft 11 in) wide, and its ground clearance was 190 to 400 mm (7.5 to 15.7 in).
Compared to that of other World War I tanks, the A7V's road speed was quite high, but the vehicle had very poor off-road capability and a high centre of gravity, which made it prone to getting stuck or overturning on steep slopes. The large overhang at the front and the low ground clearance meant that trenches or very muddy areas were impassable. The driver's view of the terrain directly in front of the tank was obscured by the vehicle's hull, which meant that there was a blind spot of about 10 metres (33 ft). However, in open terrain, the A7V could be used to some success, and offered more firepower than thearmoured carsthat were available.
Combat history[edit]
St. Quentin Canal[edit]
The A7V was first used in combat on 21 March 1918. Five tanks ofAbteilung I(Detachment I) under the command ofHauptmannGreiff were deployed north of theSt. Quentin Canal.Three of the A7Vs suffered mechanical failures before they entered combat; the remaining pair helped stop a minor British breakthrough in the area, but otherwise saw little combat that day.
Villers-Bretonneux[edit]
Three detachments (Abteilungen) of tanks were assigned to an attack in April 1918 atVillers-Bretonneuxat the head of the four German divisions spread over a 6.4-kilometre (4 mi) front. Two tanks broke down en route, but the 13 that saw action achieved some success, and the British recorded that their lines were broken by the tanks.
The first and second tank-against-tank combat in history took place on 24 April 1918 when three A7Vs (including chassis number 561, known asNixe) taking part in an attack with infantry incidentally met three BritishMark IVs(two female machine gun-armed tanks and one male with two6-pounder guns) near Villers-Bretonneux. During the battle, tanks on both sides were damaged. According to the British lead tank commander,Second LieutenantFrank Mitchell, the female Mk IVs fell back after being damaged by armour-piercing bullets. They were unable to damage the A7Vs with their own machine guns. Mitchell then attacked the lead German tank, commanded bySecond LieutenantWilhelm Biltz,[9]with the 6-pounders of his own tank and knocked it out. He hit it three times, and killed five of the crew when they bailed out. He stated that he then went on to rout some infantry withcase shot.The two remaining A7Vs in turn withdrew. As Mitchell's tank withdrew from action, seven BritishWhippet tanksalso engaged the German infantry. Three of these were knocked out in the battle, and it is unclear if any of them engaged the retreating German tanks but they did carry out an attack on two German battalions in the open to the rear causing them to break and flee.[10]Mitchell's tank lost a track towards the end of the battle due to damage from an explodingmortarshell and was abandoned. The damaged A7V limped back to the German lines, but eventually broke down. It was later destroyed by a German demolition squad, to prevent its capture and reuse by the Allies. During the same day however, another tank-against-tank fight took place where an A7V engaged a group of Whippet tanks and destroyed one of them.[11][12]
A counterattack later re-established the Allied line, by which time three A7Vs were out of action in No Man's Land or behind German lines. Nixe was badly damaged, and a German team destroyed it with explosive charges during the night of the 24th. Elfriede had overturned; it was righted and recovered from No Man's Land three weeks later by French troops and British tanks, and handed over to the French for examination. Mephisto lay stuck in a crater behind German lines for almost three months. After the area was taken by Australian troops, in July, the tank was towed to the rear by British tanks and, eventually, transported to Australia.
Other actions[edit]
In May, A7Vs were used with limited success in an attack on the French nearSoissons,during theThird Battle of the Aisne.
On 15 July, atReims(during theSecond Battle of the Marne), the Germans put eight A7Vs and 20 captured Mk IVs against the French lines. Although 10 of the Mk IVs were lost in this action, no A7Vs were lost.
The final use in World War I of A7Vs was in a small but successful action on 11 October 1918, nearIwuy.
Assessment[edit]
Germany did not consider the A7V a success and planned other designs. However, the end of the war meant none of the other tanks in development or planned ones – such as theSturmpanzerwagen Oberschlesienand the 120-tonK-Wagen– would be finished.
With only 20 produced, the A7V made only a very minor contribution to the German war effort in World War I, and the approximately 50 captured British Mark IV tanks (renamedBeutepanzerin German operation) the Germans fielded in action during the war outnumbered the A7V.[13]In contrast, the French produced over 3,600 of their lightRenault FT,the most numerous tank of World War I, and the British over 2,500 of theirMark I, II, III, IV, V, and V*heavy tanks.
After the war[edit]
Two vehicles closely resembling the A7V, one of which was namedHedi,were among several used byKokampf,aFreikorpstank unit, to quell civil unrest in Berlin in 1919. They were constructed using the chassis fromÜberlandwagenand armed with fourMG08/15machine guns. It is not known whether the vehicles were armour-plated.[14]
There is a popular myth that France handed over several A7Vs to Polish forces, which used them during thePolish–Soviet Warin 1919–1920. However, reliable sources dismiss the idea because the fate of each A7V that saw service in World War I is known and includes no transfers toPolandand there is no known official record or photographic evidence of A7Vs in Polish service.[15][16]
The design of the A7V is featured on the 1921 Tank Memorial Badge, awarded to German veterans of World War I who served as tank crewmen.

Variants[edit]
- A7V-U:(umlaufende Ketten= "tracks running all the way round" ). An attempt to reproduce the all-terrain capability of the British tanks, the A7V-U was still based on the Holt chassis but had a rhomboidal hull and all-round tracks. The cab was similar to, but bigger than, that on the A7V and was mounted on top of the forward part of the hull. Two 57 mm guns were carried in sponsons similar to the British type. The prototype was built in June 1918; trials showed that it was nose-heavy and had a high centre of gravity, and the 40-ton weight caused manoeuvrability problems. On the assumption that the problems could be rectified, 20 were ordered in September 1918, the same month work on the design was halted.[8]
Drawings for two improved designs were prepared, but the war ended before any were produced.
Thirty chassis were assigned for completion asÜberlandwagensupply carriers, but not all were completed before the end of the war.
- A7V Flakpanzer:Its engine was placed under the driver's compartment, which had a tarpaulin holder to cover the driver from bad weather, ammo boxes were placed around the driver's compartment and beneath the gun themselves.[20]It is claimed that it was armed with two Russian76 mm divisional gun M1902field guns on the first two prototypes of the A7V Flakpanzer.[21]The third prototype of the A7V Flakpanzer was armed with a Krupp-Manufactured 7.7 cm (3.03 in) leichte Feld Kanone 1896 n/a, only one l.F.K 1896 was mounted onto the vehicle.[20]No paperwork related or mentioning these weapons has been found.[21]
Surviving example[edit]
The only surviving A7V isMephisto,which was abandoned by its crew during the Battle of Villers-Bretonneux in April 1918. It was recovered three months later by British and Australian troops, and taken to Australia in 1919 as a trophy. The vehicle stood outside the old Queensland Museum in Bowen Hills,Brisbane,under an open-sided shelter for many years until being moved into the newQueensland Museumon Southbank in 1986. It was damaged by floodwater in 2011, and taken for restoration to theWorkshops Rail Museum,North Ipswich, Queensland. After restoration it was displayed at theAustralian War Memorial,Canberra,from 2015 until 2017. It has now been returned to the Queensland Museum.[22]
The cannon from A7V 504Schnuckis on display at theImperial War Museum NorthinManchester.
Replicas[edit]
There are numerous modern replicas, made to look like the original, many made of wood and modern materials:
- A running replica was built in 2009 by Bob Grundy of British Military Vehicles, Wigan, UK, a company that specialises in the restoration of old military vehicles. The replica is constructed of plywood and angle iron, using the engine, transmission and tracks from twoFordsonCounty Crawlers – tracked agricultural vehicles – and is painted to represent A7V number 504,Schnuck.It was purchased byThe Tank Museum,Bovington, in November 2012. It is on display inside the museum, and takes part in outdoor displays alongside the museum's replicaBritish Mark IVthat was constructed for the filmWar Horse.[23]
- A static replica is in theDeutsches PanzermuseuminMunster.It is namedWotan,but is largely based on the surviving example,Mephisto.
- A mobile mock-up of an A7V appears in the East German feature filmTrotz Alledem(1972), the story ofKarl Liebknechtand the 1919Spartacist uprisinginBerlin.[24]
- A mock-up is among the vehicles at the Milovice Tankodrome in the Czech Republic.[25]
