The design and development of military weapons is essentially the same as any other engineering problem: firstly identify the true problem; secondly consider alternative solutions: thirdly, apply the most promising solution: fourthly, analyse the results and consider whether they represent as acceptable solution and whether further work is required.
Why Was the Tank Invented?
Such a scheme was pressed during World War 1 with a view to overcoming the Trench warfare stalemate prevailing in France by 1916 When war was declared in 1914 the German army under the command of General Moltke implicated the Schlieffen plan which was to sweep through Belgian and on through the north-east of France and encircle Paris thus splitting the French Army in two. Great Britain sent her small but professional Army to France in August 1914 under the leadership of General French a veteran of the Boar War, after a heroic stand and retreat at Mons in Belgium plus the French holding the Germans on the Somme salient the German thrust came to a halt and a Trench system was set up from the Coast of Belgium right through to the Swiss Alps, and by 1916 stalemate had been made, the German Army had many machine guns and also a vastly superior Trench system to the allied army, many assaults made by the French and British armies ended up in mass slaughter, Haig who has replaced French by early 1916 tried to overcome the dwindling numbers in the regular Army by forming new companies of Volunteers called “Kitchener’s Army” but all they became was another statistic of the slaughter, so the Army were looking for a machine which could cut through the barb wire and go over the German Trench and knock out the machine gun posts.
Political and military minds gave considerable thought to the problem and came up with various possible solutions such as coupled steamrollers, a giant three-wheeled leviathan, or an articulated troop carrier.
