Putting aside the two battles which we have last examined, we may say that for the first 150 years of their career the Swiss were so fortunate as never to meet either with a master of the art of war, or with any new form of tactical efficiency which could rival their own phalanx. It was still with the mailed horsemen or the motley and undisciplined infantry-array of the middle ages that they had to deal. Their tactics had been framed for successful conflict with such forces, and continued to preserve an ascendancy over them. The free lances of Enguerrand de Coucy, the burghers and nobles of Swabia, the knights who followed Frederick or Leopold or Sigismund of Hapsburg, were none of them exponents of a new system, and served each in their turn to demonstrate yet more clearly the superiority of the Confederates in military skill. Even the most dangerous attack ever aimed against Switzerland, the invasion by the ‘Armagnac’ mercenaries of the Dauphin Louis in 1444, was destined to result in the increase of the warlike reputation of its soldiery. The battle of St. Jacob, mad and unnecessary though it was, might serve as an example to deter the boldest enemy from meddling with men who preferred annihilation to retreat. Possessed by the single idea that their phalanx could bear down any obstacle, the Confederates deliberately crossed the Birs in face of an army of fifteen times their strength. They attacked it, broke its centre, and were then surrounded by its overwhelming numbers. Compelled to ‘form the hedgehog’ in order to resist the tremendous cavalry charges directed against them, they remained rooted to the spot for the remainder of the day. The Dauphin launched squadron after squadron at them, but each in its turn was hurled back in disorder. In the intervals between these onsets the French light troops poured in their missiles, but though the clump of pikes and halberds grew smaller it still remained impenetrable. Not until the evening was the fighting ended, and then 6000 Armagnacs lay dead around the heap of Swiss corpses in the centre. Louis saw that a few such victories would destroy his whole army, and turned back into Alsace, leaving Switzerland unmolested.
