This rapidly-increasing wealth and power, did but increase his energy and his spirit of encroachment. And yet he adopted principles of honor which were far from common in that age of barbaric violence. He would never stoop to ordinary robbery, or harass peasants and helpless travelers, as was constantly done by the turbulent barons around him. His warfare was against the castle, never against the cottage. He met in arms the panoplied knight, never the timid and crouching peasant. He swept the roads of the banditti by which they were infested, and often espoused the cause of citizens and freemen against the turbulent barons and haughty prelates. He thus gained a wide-spread reputation for justice, as well as for prowess, and the name of Rhodolph of Hapsburg was ascending fast into renown. Every post of authority then required the agency of a military arm. The feeble cantons would seek the protection of a powerful chief; the citizens of a wealthy town, ever liable to be robbed by bishop or baron, looked around for some warrior who had invincible troops at his command for their protection. Thus Rhodolph of Hapsburg was chosen chief of the mountaineers of Uri, Schweitz and Underwalden; and all their trained bands were ready, when his bugle note echoed through their defiles, to follow him unquestioning, and to do his bidding. The citizens of Zurich chose Rhodolph of Hapsburg as their prefect or mayor; and whenever his banner was unfurled in their streets, all the troops of the city were at his command. The neighboring barons, alarmed at this rapid aggrandizement of Rhodolph, formed an alliance to crush him. The mountaineers heard his bugle call, and rushed to his aid. Zurich opened her gates, and her marshaled troops hastened to his banner. From Hapsburg, and Rheinfelden, and Suabia, and Brisgau, and we know not how many other of the territorial possessions of the count, the vassals rushed to the aid of their lord. They met in one of the valleys of Zurich. The battle was short, and the confederated barons were put to utter flight. Some took refuge in the strong castle of Balder, upon a rocky cliff washed by the Albis. Rhodolph selected thirty horsemen and thirty footmen. "Will you follow me," said he, "in an enterprise where the honor will be equal to the peril?"
