History of creation and combat usage

Development

The British development on their cruiser tanks, tanks that focus on mobility to exploit breakthroughs beyond enemy lines, took a turn in 1936 after General Giffard LeQuesne Martel became the Assistant Director of Mechanization at the British War Office, the head of the army in the government. Martel, an advocate of the tanks and developed the concept of "tankettes", witnessed a tank demonstration in 1936 that had Soviet designs, with the one that attracted his attention was the BT light tank. The BT's use of the Christie suspension has Martel argue for the usage of the same suspension in their tank designs, to which the British government complied with the purchase and licensing of the system from the Nuffield Organization.

The acquired vehicle from the purchase of the Christie suspension was labeled as the A13E1 and became part of the design development under the designation Cruiser Mk III (A13). The General Staff requested for the vehicle to have 30 mm of armour, a 2-pounder gun, and a road speed of 48 km/h. The original vehicle was extensively reworked due to many interior and mechanical issues. Until the tank design was finished, the British Army adopted the Cruiser Mk I (A9) tank for use, but these tanks were delayed due to the A13's near completion. The first prototype was delivered in 1937 under the name A13E2, this featured the turret from the A9 cruiser tank, with a 2-pounder and a Vickers machine gun. The armour on the prototype was 15 mm and the design could reach a top speed under a governor of 48 km/h (64 km/h ungoverned). The last and revised design was the A13E3 that became adopted by the British Army and ordered into production in 1939. The General Staff specification number for the tank was the A13 Mk. I, Cruiser Tank Mark III. 65 of these tanks were ordered from the Nuffield Mechanization & Aero Limited, to which 30 were built before War Office decided to upgrade the A13 Mk.I with more armour than the A13 Mk.II, Cruiser Tank Mk IV. Some of the A13 Mk.I Cruiser Mk III were also converted into Mk IV as well to stay modernized.

Combat Usage

The A13 first saw combat in the Battle of France under the British Expeditionary Force in 1940. The A13 encountered many trouble during its employment, the crew have little to no training with the new tanks due to their rushed adoption into service, the tanks were in poor condition and some were even missing parts. The A13s were used in the 1st Armoured Division, but many were either destroyed by the superior German armoured forces or abandoned at Calais during the evacuation of Allied troops at Dunkirk, which forced the units to leave behind their heavier equipment. The 3rd Royal Tank Regiment was a part of the 1st Armoured Division and saw combat at the Siege of Calais during the Battle of France, using the A13 cruiser tanks as part of its forces. Like the entire 1st Armoured Division, most of the Regiment's heavy equipment and tanks were left behind as the surviving soldiers evacuate at Dunkirk.

After the disaster at France, the A13 were still used to support the war. Some were sent to Greece to support their defense against Germany in the Battle of Greece, but a majority were sent to North Africa as part of the Western Desert Campaign near Libya under the 7th Armoured Division. Compared to the time in France, the A13s in North Africa fared much better, ironing out most of its initial defects, and was even more suited to the environment than other tank designs. The A13 was popular with the crew for its high speed, reliability, and a powerful 2-pounder cannon that could engage a majority of Axis tanks in 1941. However, there was an insufficient number of A13s available for use, so tank units were mixed with the faster cruiser tanks and slower infantry tanks, which caused tactical and logistical difficulties trying to accommodate all of the tanks. Another deficiency with the tank and every other British tank with the 2-pounder was the lack of high-explosive shell issued to the tankers, which made them vulnerable to anti-tank guns, which caused a majority of British tank losses in the North African Campaign. Still, the A13 fared very well with its armour and armament until the late 1941 where better armoured Panzer IIIs and Panzer IVs began to appear on the battlefield.

Due to its growing obsolesce on the battlefield, the A13 was replaced in 1941 by the better armoured A15 Crusader tank.
