Austria was in vain remonstrating against his {72} occupation of Italy, while the czar of Russia and Gustavus of Sweden were also protesting against his encroachments on the territory of the weaker powers. A new coalition was now formed against him of England, Russia, Austria and Sweden. Prussia remained neutral. General Mack, who had shown his incapacity in 1798, was unfortunately placed at the head of the Austrian army, while the more capable Archduke Charles commanded in Italy where General Massena led the French army. With one of those sudden coups for which he was famous, Napoleon withdrew his "Army of England" to march to the Rhine and ordered other troops from Holland, France and Hanover to meet them there. This formed what was called the "Grand Army," commanded in person by the emperor. No coalition was able to withstand his victorious progress. But England held the sea. On October 17th, 1805, General Mack was surrounded at Ulm, and surrendered with two hundred thousand men. The French entered Vienna on November 15th. The Russian army under the Emperor Alexander in person had assembled in Moravia. Being joined by some Austrian divisions it amounted to about eighty thousand men. Then came the great battle of Austerlitz on December 2nd. Both armies were about equal in numbers but the Russians extended their line too much. The slaughter among the allies was terrific and thousands were drowned trying to cross the half frozen lakes in the rear. {73} "Roll up the map of Europe," said the dying Pitt, when he heard of these disasters, "it will not be wanted these ten years." After his crushing defeat the czar had an interview with Napoleon when an armistice was agreed upon and the Russians were allowed to return to their own country. On December 27th peace was signed between Austria and France, the former giving up Dalmatia and the Venetian provinces to Italy. While these events were occurring in Europe the feeling in the United States against England was becoming more and more bitter. The news from America was so threatening that Colonel Brock, who was in Guernsey, determined to go back to Canada before the expiration of his leave. He left London, never to return, on June 26th, 1806, and sailed from Cork in the _Lady Saumarez_, a Guernsey vessel well manned and armed as a letter of marque bound to Quebec. His sister wrote on the 27th, "Isaac left town last evening for Milford Haven. Dear fellow; Heaven knows when we shall see him again!"
