The story of the creation of the tank is one of pioneering innovation, frustrated military aspirations and lost opportunities. At the time, rather surprisingly, it did not lead to an arms race because the other side chose to ignore it. What follows is designed to provide both a visual guide and brief assessment of the birth of modern armoured warfare. Despite contributing to the defeat of Imperial Germany in 1918, the latter ironically sowed the seeds for the Nazi concept of Blitzkrieg. Although the Battle of Cambrai is held up as the very first tank battle this is in fact a myth, as tanks had already fought at Flers-Courcelette during the Somme offensive, Arras, Passchendaele and Berry-au-Bac. Nor was it the largest tank battle, as the Allied sledgehammer assault at Amiens involved far greater numbers.
The tank concept was developed as a solution to the dreadful impasse that developed on the Western Front during the First World War. British innovation was driven by the need to overcome enemy trenches and strongpoints: indeed by the time the Germans developed their own tanks the first tank-to-tank actions were but a footnote to the conflict.
Although the origins of modern armoured and mechanized warfare date from the First World War, it was not an easy birth. Britain, France and Germany developed armoured fighting vehicles that universally became known as the tank to help break the deadlock of trench warfare. The British and French easily led the way as the Germans were well behind the curve. Getting the balance of power-to-weight ratio and armament just right proved to be a very tricky and often deadly business. Apart from the British Whippet and the French FT all the tanks of this period were little more than lumbering landlocked battleships. Nonetheless, their use at Cambrai and Amiens showed the way ahead.
Essentially First World War British heavy tanks were designed as a breakthrough weapon akin to the later heavy German Tiger and Soviet KV tanks of the Second World War. It was the French who subsequently ran with the concept of a light tank during the First World War intended to exploit a breakthrough. Both British heavy and French light tanks achieved mixed results during 1916–18 but they laid the foundations for all future armoured and mechanized warfare.
Throughout history cavalry had played an often decisive part in battle by combining mobility, protection and offensive power. They regularly brought terror to the enemy by turning a flank, exploiting a breakthrough and by pursuing a demoralized and defeated army. Led by noblemen and gentlemen, the thrill was in the chase. Eventually improvements in firearms technology inevitably meant that the weight of the fighting always rested on the infantry. In the aftermath of the Napoleonic Wars the introduction of the rifle gave the infantry a weapon with a range of 1,000 yards that spelt the end of the cavalry charge. Likewise the evolution of artillery and artillery tactics changed how cavalry were used.
By the time of the American Civil War cavalry were increasingly being employed as mounted infantry or dragoons. Europe learned the hard way during the Franco-Prussian War that the cavalry charge was now all but redundant in the face of devastating firepower. Similarly the British Army also learned the same lesson in South Africa during the Boer War. Mounted Boer riflemen easily outfought British cavalry who persisted in keeping the lance and sabre. It was only when the British deployed large numbers of mounted units which fought dismounted that the Boers were finally defeated. At the beginning of the First World War such lessons were largely ignored across much of Europe.
On the eve of war Europe was still hopelessly in love with the glamour and dash of the cavalry. It was a career that appealed to many of Europe’s aristocracy. On the Western Front some ten French and one British cavalry divisions found themselves confronted by a similar number of German cavalry divisions. Initially, as a result of the Schlieffen Plan, the war was very fluid with the German armies swinging rapidly through Belgium. Very briefly the cavalry and horse artillery had their moment of glory.
Once the German advance had been stopped on the Aisne, the fighting took on a completely different complexion. The cavalry became separated and hemmed in by vast trench systems that they were powerless to prevent being constructed. Again the generals failed to appreciate that the need was for mobile mounted riflemen, not old-style European cavalry still brandishing the lance and sabre as if it were yesteryear.
Cavalry became useless and infantry assaults supported by massive artillery bombardments the order of the day. The battlefield was churned up and shorn of all vegetation turning it into a desolate lunar like landscape. Once the rains came the area between the opposing trenches turned into a sea of mud and became called No Man’s Land for good reason. Both the British and French generals decided that attack was the best form of defence and proceeded to fight a war of attrition against the German defences. Their aim was to wear Germany down no matter the appalling cost in human lives.
In 1915 both sides tried to break the deadlock by resorting to poison gas. The Germans first used it at the Second Battle of Ypres when they gassed the British in the Ypres Salient. The British then employed it during the Battle of Loos. It proved not to be a decisive weapon and simply added to the suffering and misery of those in the trenches. Both sides quickly learned how to cope with this new horror. By 1916 there was deadlock and in desperation the British and the French began secretly developing the ‘tank’ in an effort to break through on the Somme.
The popular perception is that Winston Churchill was the founding father of the tank, an accolade which he thoroughly enjoyed. In fact Ernest Swinton and David Lloyd George were the greatest driving forces, Swinton for his tenacity in pushing the concept forward and Lloyd George for ensuring the Army did not thwart the programme at the crucial moment after the second phase of the Battle of the Somme. Hugh Elles, John Fuller and John Monash also featured prominently as pioneers in the evolution of the world’s very first tank force – the British Tank Corps. In France Jean Estienne was the leading light in creating French tanks. Likewise George Patton Jr was responsible for forming America’s very first tank units.
Field Marshal Sir Douglas Haig remains a controversial figure thanks to his command of the British Expeditionary Force and his conduct of the war on the Western Front. His name will forever be associated with the slaughter on the Somme. However, it was he who advocated the expansion of the Tank Corps. In contrast Haig’s superior, the Chief of the Imperial General Staff General Sir William Robertson, and his subordinate General Sir Henry Rawlinson were far from enthusiastic supporters of the tank concept. If anything Haig was over-optimistic about the fledgling tank’s capabilities. On the other hand Rawlinson was initially completely baffled by it.
Following their success against the Russians Generals Hindenburg and Ludendorff were sent to command the Western Front. They moved to strengthen German defences and behind their front lines created new fortifications known as the Hindenburg Line. Once this was complete they withdrew to these much stronger defences in early 1917. This resulted in another dreadful slogging match with British tanks failing to deliver the desired result at the Battle of Cambrai.
The tank did not come of age until 1918. Morale in the German Army by this stage was poor and desertion rife. The German high command’s reactionary thinking when it came to this newfangled armoured warfare served the common soldier poorly. Even though German generals scoffed at the utility of Britain and France’s tanks, soldiers were calling them Deutschland’s Tod or ‘Germany’s Downfall’.
While the Allies were producing tanks in ever-growing numbers the Germans were slow to follow and failed to develop really effective anti-tank tactics and weapons. Only after the French Army’s use of masses of Renault tanks during the counter-attacks on the Marne did the German high command reverse its thinking. By this stage in the fighting it was simply too late. Instead Ludendorff pinned his hopes in victory on his ‘stormtroopers’ who spearheaded the German Spring Offensive of 1918. While the results were remarkable, they were not enough.
The Allies launched a surprise attack on 8 August 1918 at Amiens that heralded the end of the First World War. This was supported by over 600 tanks, the largest number to have ever been active in any of the battles of the conflict. In total the British Army committed a dozen tank battalions and they along with over twenty Allied divisions left 500,000 German casualties in their wake. Just 100 days later the war came to an end with the Armistice on 11 November 1918. The tank had proved to be Germany’s downfall.
