La Guerre des Savants
In retrospect it may seem surprising, but German military planners were in fact supremely unconcerned about Russia during the years of the treaty restrictions. Fear of a revanchist attack was sometimes deployed as a political tool, but the Generalstab did not share it. Their main worry was France, and this view was increasingly shared across the Rhine. Following a few heady years of celebration at the end of the dreaded 'demographic superiority' of their eastern neighbour, France's generals were forced to face up to a painful reality: the German army, though smaller both in establishment strength and potential than it would have been without the losses of 1906-08, outclassed theirs in too many respects. This was exacerbated by years during which the Clemenceau government had told the public the threat from Berlin had been vanquished and poured money into countering British supremacy at sea. Something had to be done.
The most obvious solution – a three-year conscription mooted before 1906 – was politically impossible. The voting public would not have accepted it, and the French economy suffered unreasonably. Instead, the government decided to invest heavily in technological solutions, trying to duplicate the relative success of its naval programme on land. French soldiers would deter or defeat a German assault not through the weight of their numbers or their Gallic élan, but through the superior firepower of their artillery, the range of their bombing aeroplanes, and the omniscience of their intelligence services. Science – ingenious, cutting-edge technology - was what France did best. It might not match Britain in global reach, Germany in industrial weight, or America in sheer wealth, but it dared challenge all comers in the realm of brainpower.
The result was what later generations would refer to as an arms race, though the term was not then in common use. German intelligence was alarmed by reports of French advances and significant funds were made available to counter them. The resulting game of espionage and counterintelligence, guesswork, and secret research defined a political era and in its white-hot phase produced weapons technology that would have made an actual war possibly the deadliest conflict ever fought in human history.
Technological competition began and was most intense in artillery. The French and German armies differed in doctrine more than technological advancement; the backbone of Germany's force was the 10cm howitzer while that of the French army was its innovative 75mm field gun designed for mobility and rapid fire. What the French excelled in and the Germans only imperfectly copied were highly effective fire control systems. Field telephone and later radio networks, sophisticated calculators and rigorous training functioned as a force multiplier that allowed French artillery to concentrate fire in smaller areas and shorter timespans than any other military on earth. The vaunted German supremacy in heavy siege guns never made up for this, though their efforts to duplicate it would prove effective enough on the Russian front.
Germany enjoyed an early lead in chemical weaponry, but this quickly evaporated as both militaries established arsenals of standard lachrymant gases, phosgene, 1410, chloroarsenic and urticants. The development of nerve agents by German scientists in the early 1930s was intended to break the stalemate, but merely moved it to a higher level as French intelligence acquired the formulae. Ultimately neither side ever dared deploy these gases for fear of their uncontrollable impact as much as of retaliation.
France, outclassed in airships by the Zeppelin AG, concentrated heavily on defensive weapons to deny the German Luftmacht its airspace. Aeroplanes and artillery were the backbone of this effort, and France's lead in heavier-than-air flight became more significant as the technology matured. A secondary outcome of this race was rocketry, a technology that did not fulfil initial expectations of deterring aerial attacks, but would cement French leadership in ballistic missile and aerospace technology for a generation.
Beyond these grand arenas, technological rivalry extended into hundreds of smaller issues, from optical equipment to diving gear, smallarms (the semiautomatic fusil 38 was a triumph of engineering that outclassed its German rival in every regard), pharmaceuticals and electronics. The usefulness of many inventions is in doubt – whether the French chain of listening and ranging posts along the frontier would have achieved anything against a concerted air offensive may be questioned, and Germany's submersible torpedo boats, constructed at great cost, would have fallen prey to French echolocation quickly. But altogether, the epoch produced advances that were rarely rivalled in human history and civilian technology from computers to bacteriocides to turbine engines and, of course, the eventual world-changing reality of the atomic bomb.
