On the 9th of November the Assembly decreed that the _emigres_ assembled on the frontiers should be liable to the penalties of death and confiscation unless they returned to France by the 1st of January following. Louis did not love his brothers, and he detested their policy, which without rendering him any service made his liberty and even his life precarious; yet, loath to condemn them to death, he vetoed the decree. On the 29th of November the Assembly decreed that every nonjuring clergyman must take within eight days the civic oath, substantially the same as the oath previously administered, on pain of losing his pension and, if any troubles broke out, of being deported. This decree Louis vetoed as a matter of conscience. In either case his resistance only served to give a weapon to his enemies in the Assembly. But foreign affairs were at this time the most critical. The armed bodies of _emigres_ on the territory of the Empire afforded matter of complaint to France. The persistence of the French in refusing more than a money compensation to the German princes who had claims in Alsace afforded matter of complaint to the Empire. Foreign statesmen noticed with alarm the effect of the French Revolution upon opinion in their own countries, and they resented the endeavours of French revolutionists to make converts there. Of these statesmen, the emperor Leopold was the most intelligent. He had skilfully extricated himself from the embarrassments at home and abroad left by his predecessor Joseph. He was bound by family ties to Louis, and he was obliged, as chief of the Holy Roman Empire, to protect the border princes. On the other hand, he understood the weakness of the Habsburg monarchy. He knew that the Austrian Netherlands, where he had with difficulty restored his authority, were full of friends of the Revolution and that a French army would be welcomed by many Belgians. He despised the weakness and the folly of the _emigres_ and excluded them from his councils. He earnestly desired to avoid a war which might endanger his sister or her husband. In August 1791 he had met Frederick William II. of Prussia at Pillnitz near Dresden, and the two monarchs had joined in a declaration that they considered the restoration of order and of monarchy in France an object of interest to all sovereigns. They further declared that they would be ready to act for this purpose in concert with the other powers. This declaration appears to have been drawn from Leopold by pressure of circumstances. He well knew that concerted action of the powers was impossible, as the English government had firmly resolved not to meddle with French affairs. After Louis had accepted the constitution, Leopold virtually withdrew his declaration. Nevertheless it was a grave error of judgment and contributed to the approaching war.
