To these mounted infantry the name of dragoons was given, and so useful were they found that the institution was adopted in other armies, and dragoons became a recognized portion of every military force. In time the custom of dismounting and fighting on foot was gradually abandoned, and dragoons became regular cavalry; but in modern times the utility of Gustavus's invention of mounted infantry has been again recognized, and in all the small wars in which England has been engaged bodies of mounted infantry have been organized. Ere long mounted infantry will again become a recognized arm of the service. But these raids in search of provisions occupied but a small portion of the army. The rest passed their time in enforced idleness. There was nothing to be done save to clean and furbish their arms and armour; to stand on the ramparts and gaze on the distant heights of the Alte Veste, to watch the solid columns of the Imperial army, which from time to time Wallenstein marched down from his stronghold and paraded in order of battle, as a challenge to the Swedes to come out and fight, or to loiter through the narrow streets of Nuremberg, and to talk to the citizens, whose trade and commerce were now entirely at a standstill. Malcolm, with the restlessness of youth, seldom stayed many hours quiet in camp. He did not care either for drinking or gambling; nor could he imitate the passive tranquillity of the old soldiers, who were content to sleep away the greater part of their time. He therefore spent many hours every day in the city, where he speedily made many acquaintances. In the city of Nuremberg time dragged as slowly as it did in the camp. At ordinary times the centre of a quiet and busy trade, the city was now cut off from the world. The shops were for the most part closed; the artisans stood idle in the streets, and the townsfolk had nought to do, save to gather in groups and discuss the times, or to take occasional excursions beyond the gates into the camp of their allies. The advances then of the young Scottish officer were willingly responded to, and he soon became intimate in the houses of all the principal citizens; and while the greater part of his comrades spent their evenings in drinking and gambling, he enjoyed the hours in conversation and music in the houses of the citizens of Nuremberg. The long inaction brought its moral consequences, and the troops became demoralized and insubordinate from their enforced idleness. Plundering and acts of violence became so common that Gustavus was obliged to issue the most stringent ordinances to restore discipline; and an officer and many men had to be executed before the spirit of insubordination was quelled. In order to pass some of the hours of the days Malcolm obtained leave from one of the great clockmakers of the town--for Nuremberg was at that time the centre of the craft of clockmaking--to allow him to work in his shop, and to learn the mysteries of his trade.
