At other times, the French had boasted of their rapidity of action, but upon this occasion they were outstripped by the Germans. An army of the confederates entered Alsace before Henry made his appearance there, and an Austrian army, which the Bishop of Strasburg and Passau had assembled in that quarter for an expedition against Juliers, was dispersed. Henry IV. had formed his plan as a statesman and a king, but he had intrusted its execution to plunderers. According to his design, no Roman Catholic state was to have cause to think this preparation aimed against itself, or to make the quarrel of Austria its own. Religion was in nowise to be mixed up with the matter. But how could the German princes forget their own purposes in furthering the plans of Henry? Actuated as they were by the desire of aggrandizement and by religious hatred, was it to be supposed that they would not gratify, in every passing opportunity, their ruling passions to the utmost? Like vultures, they stooped upon the territories of the ecclesiastical princes, and always chose those rich countries for their quarters, though to reach them they must make ever so wide a detour from their direct route. They levied contributions as in an enemy's country, seized upon the revenues, and exacted, by violence, what they could not obtain of free-will. Not to leave the Roman Catholics in doubt as to the true objects of their expedition, they announced, openly and intelligibly enough, the fate that awaited the property of the church. So little had Henry IV. and the German princes understood each other in their plan of operations, so much had the excellent king been mistaken in his instruments. It is an unfailing maxim, that, if policy enjoins an act of violence, its execution ought never to be entrusted to the violent; and that he only ought to be trusted with the violation of order by whom order is held sacred. Both the past conduct of the Union, which was condemned even by several of the evangelical states, and the apprehension of even worse treatment, aroused the Roman Catholics to something beyond mere inactive indignation. As to the Emperor, his authority had sunk too low to afford them any security against such an enemy. It was their Union that rendered the confederates so formidable and so insolent; and another union must now be opposed to them.
