The Tank, Cruiser, Mk V, Covenanter (A13 Mk III) was a British Cruiser tank of the Second World War. It was named for the Covenanters, a Scottish religious faction in the British Isles at the time of the Wars of the Three Kingdoms. The Covenanter was the first cruiser tank design to be given a name.
History
In 1938, the War Office had issued a requirement for a new, better armoured cruiser tank to replace the Cruiser IV. Nuffield's A16 design was found to be too expensive, and in 1939 a cheaper A13 Mk III was adopted. London, Midland and Scottish Railway Company (LMS) designed the hull. The turret was designed by Nuffield, with Henry Meadows designing the engine. On 17 April, before even a single prototype was produced, the first 100 vehicles were ordered from the LMSR. Additional orders soon followed, with English Electric and Leyland Motors joining the production effort, for a final production total of 1,771 Covenanters. Nuffield was also approached, but preferred to design its own offspring of the A13 line, which became the Cruiser Mk.VI Crusader.
In an attempt to keep the vehicle as low as possible, a low-profile, horizontally-opposed engine was used. The configuration left no room for radiators in the engine compartment, and so the radiators were moved to the front of the vehicle. The unusual arrangement, combined with the rushed design process, resulted in serious problems with engine cooling. These problems meant that the Covenanter could not be employed in the North African Campaign. Instead, Crusader and American tanks were sent to Africa, while the Covenanters remained in the British Isles.
By late 1943 the Covenanter was considered too weakly armed and armoured to deal with new German tanks. It was decided that neither problem could be addressed without significant changes in the design, so the tank was declared obsolete and all vehicles except the bridgelayer variant were scrapped.

radiator covers at the left front. Note also the
Valentine-type gun mantlet. Except for some early production vehicles, most Covenanters received a different mantlet as shown in the main picture at top.
Combat usage
Except for a few trial vehicles, Covenanters were never deployed outside of the British Isles. The British 1st Armoured Division was equipped initially with them, but when it was sent to Egypt, the tanks were transferred to the 9th Armoured Division. Eventually a handful of vehicles were sent to the desert for service trials and were allocated to the REME for maintenance and evaluation. It is not clear if these tanks were ever used in combat although the unit markings indicate they may have been deployed alongside Kingforce with their experimental Churchill Mk II tanks. Covenanters were also issued to some Polish units formed in the UK; they were replaced before these units were sent to the frontline, except for a few bridgelayers the Poles retained and used in their advance through Belgium and the Netherlands. The only Covenanter gun armed tank known to have been lost to enemy action was destroyed by a German air raid on 31 May 1942 in Canterbury.
Bridgelayer versions were also extensivly used by the Australian forces in the Pacific Campaign.
