The First World War forced military science to swap history lessons for experiments
Before 1914, officers studied war mainly by combing through past battles for lessons to repeat. That method told Europe's planners that bold, relentless attack was the only road to victory. The Western Front proved how badly history could mislead, and out of that failure grew a more experimental, technology-minded military science.
The field once carried real mystique. Until the Second World War it was often written with capitals in English and ranked as an academic discipline beside physics and medicine. Part of the aura came from education itself: one estimate holds that as late as the 1880s three quarters of Europeans could not read, while officers had to calculate complex troop movements and design fortifications that looked like arcane knowledge to outsiders.
Change came slowly. Major John Mitchell, a British veteran of the Napoleonic Wars, felt battlefield force had hardly altered since ancient Greece, echoing Clausewitz's point that war differs from other sciences because the object being studied fights back. Later the French officer Ardant du Picq argued that combat performance depended on the psychology of individuals and groups, nudging armies toward systematic research on how soldiers actually behave.
Pre-war planners were not simply foolish. Their reading of history convinced them that heavy firepower and trench digging would freeze a battlefield and sap morale, so only attack could win. They even blamed Russia's loss to Japan on too little offence rather than too much enemy firepower. Marshal Foch, a keen student of Clausewitz, summed up the creed: in strategy as in tactics, one attacks.
After 1918 almost everything changed. Cavalry faded within two decades, supply became the science of logistics as armies fired shells faster than factories made them, and infantry learned to work with tanks and aircraft. The best troops turned out to be those valuing initiative and team cohesion over rigid discipline, such as the Australian Corps in the Hundred Days Offensive. Some ideas endure, though: the double envelopment, which Hannibal executed at Cannae in 216 BCE, is still considered the consummate manoeuvre.
