This pushed the company, united with Sir W.G. Armstrong Whitworth & Company into Vickers-Armstrong Limited in 1927, to work on creating tanks purely for export. The result of this work was the Vickers Mk.E, a tank that cemented its creators and the Vickers company in world tankbuilding history.
After the end of WWI and the inevitable downsizing of the armed forces, British officers were left without the ability to make a career in the military and decided to proceed in different directions. Some of them tried their hand at the automotive industry. Captain John Valentine Carden was among them. He worked with small cars before the war and on sport cars after, but failed to reach success in this field.
Another British Army Captain, Vivian Graham Loyd, had the same hobby. The two talented engineers met in 1923. Together, they decided to leave the automotive industry, already oversaturated with small companies, and begin producing military vehicles.
