"Centuries later knights on horseback were to learn a similar lesson in fighting from the massed infantry of Swiss soldiers who, like the Greek hoplites before them, fought with and for each other as equals. We now think of the Swiss Guards who stand on duty at the Vatican in their multicoloured Renaissance uniforms as a charming detail and Switzerland as peaceful and bucolic, home to good chocolate, discreet banks and, as the character Harry Lime in The Third Man unkindly says, the cuckoo clock. For 200 years, until a square was finally broken in 1515, the Swiss formations, bristling with pikes and sheltering archers with their deadly crossbows, were the terror of Europe and the key to victory, at least for anyone who could afford to hire them. ‘Pas d’argent, pas de Suisse,’ as the saying went."
