For too long Frankfort had looked to the Emperor, whose business it was to keep order in his domain, and when at last the merchants, combining to help themselves, made an effort towards freedom, it was too late.  The result of their combination was a flotilla of nearly a hundred boats, which, gathering at Frankfort and Mayence, proceeded together down the river, convoyed by a fleet containing armed men, and thus they thought to win through to Cologne, and so dispose of their goods.  But the robber Barons combined also, hung chains across the river at the Lorely rocks, its narrowest part, and realizing that this fleet could defeat any single one of them, they for once acted in concert, falling upon the boats when their running against the chains threw them into confusion.

The nobles and their brigands were seasoned fighters all, while the armed men secured by the merchants were mere hirelings, who fled in panic; and those not cut to pieces by their savage adversaries became themselves marauders on a small scale, scattered throughout the land, for there was little use of tramping back to the capital, where already a large portion of the population suffered the direst straits.

Not a single bale of goods reached Cologne, for the robbers divided everything amongst themselves, with some pretty quarrels, and then they sank the boats in the deepest part of the river as a warning, lest the merchants of Frankfort and Mayence should imagine the Rhine belonged to them.  Meantime, all petitions to the Emperor being in vain, the merchants gave up the fight.  They were a commercial, not a warlike people.  They discharged their servants and underlings, and starvation slowly settled down upon the distressed city.

After the maritime disaster on the Rhine, some of the merchants made a futile attempt to amend matters, for which their leaders paid dearly.  They appealed to the seven Electors, finding their petitions to the Emperor were in vain, asking these seven noblemen, including the three warlike Archbishops of Cologne, Treves, and Mayence, to depose the Emperor, which they had power to do, and elect his son in his stead.  But they overlooked the fact that a majority of the Electors themselves, and probably the Archbishops also, benefited directly or indirectly by the piracies on the Rhine.  The answer to this request was the prompt hanging of three leading merchants, the imprisonment of a score of others, and a warning to the rest that the shoemaker should stick to his last, leaving high politics to those born to rule.  This misguided effort caused the three Archbishops to arrest Prince Roland, the Emperor’s only son, and incarcerate him in Ehrenfels, a strong castle on the Rhine belonging to the Archbishop of Mayence, who was thus made custodian of the young man, and responsible to his brother prelates of Cologne and Treves for the safe-keeping of the Prince.  The Archbishops, as has been said, were too well satisfied with the weak administration then established at Frankfort to wish a change, so the lad was removed from the capital, that the citizens of Frankfort might be under no temptation to place him at their head, and endeavor to overturn the existing order of things.
