How a garage-built tankette and a modular bridge changed modern military engineering forever

History · Published 3 October 2026 Swipe more like this →

In short: Lieutenant-General Giffard Martel was a visionary British officer who pioneered tank warfare and modular bridging. From building a one-man tankette in his own garage to designing the box girder bridges that influenced the famous Bailey bridge, his technical ingenuity shaped the mechanised battlefield of the twentieth century.

Born in 1889, Giffard Le Quesne Martel—known as Q—was a career soldier and military engineer whose influence spanned both World Wars. His early exposure to tank warfare on the Somme in 1916 convinced him that armoured vehicles were the future of combat. He famously authored a paper in 1916 titled A Tank Army, which proposed forces composed entirely of armoured vehicles, a radical concept that influenced his contemporaries, including J. F. C. Fuller.

Martel’s technical contributions were equally significant. At the Experimental Bridging Establishment, he developed the Martel bridge, a modular box girder design adopted by the British Army in 1925. Its versatility was so profound that it served as a precursor to the iconic Bailey bridge. His inventiveness extended to vehicle design; in 1925, he constructed a one-man tankette in his garage. While the concept of a single-operator fighting vehicle was eventually abandoned due to the difficulty of simultaneously driving and firing, his work pushed the British Army toward the development of light tanks.

During the Second World War, Martel’s expertise in mechanisation proved vital. In 1940, he directed a counter-attack against the 7th Panzer Division at the Battle of Arras, demonstrating his tactical grasp of armoured warfare. Later, as head of the Military Mission to the Soviet Union in 1943, he provided astute analyses of Red Army tactics. He argued that Soviet battlefield experience was more relevant to the upcoming Operation Overlord than British operations in North Africa. Despite his contributions, his tenure in Moscow ended following political friction, and he retired in 1945, leaving a legacy as one of Britain's most innovative military thinkers.
