Although they were not the only ones to work on this new concept of the armoured vehicle, the British were the first to have developed it and try it out on the battlefield.
Produced in the same workshops as battleships, they were designed as "land-based cavalry". Diamond-shaped with surrounding tracks, they were equipped to shoot at the sides and have a sort of rudder at the back like ships. Eight men formed the crew and the speed was 5 km/h. "For the first time, we have used a new model of heavy armoured vehicle which has done great service", read the British press release which appeared in the newspaper Le Matin. Despite the moderate results, the appearance of these "steel monsters" caused panic in the German trenches and demonstrated the potential of this new 20th-century weapon.
