A monument for Peter III stands in Kiel (North Germany), the city of his birth. Reign Foreign policy After Peter succeeded to the Russian throne (), he withdrew Russian forces from the Seven Years' War and concluded a peace treaty () with Prussia (dubbed the "Second Miracle of the House of Brandenburg"). He gave up Russian conquests in Prussia and offered 12,000 troops to make an alliance with Frederick II of Prussia (). Russia thus switched from an enemy of Prussia to an ally—Russian troops withdrew from Berlin and marched against the Austrians. This dramatically shifted the balance of power in Europe, suddenly handing the delighted Frederick the initiative. Frederick recaptured southern Silesia (October 1762) and subsequently forced Austria to the negotiating table. As Duke of Holstein-Gottorp, Peter planned war against Denmark in order to restore parts of Schleswig to his Duchy. He focused on making alliances with Sweden and with England to ensure that they would not interfere on Denmark's behalf, while Russian forces gathered at Kolberg in Russian-occupied Pomerania. Alarmed at the Russian troops concentrating near their borders, unable to find any allies to resist Russian aggression, and short of money to fund a war, the government of Denmark threatened in late June to invade the free city of Hamburg in northern Germany to force a loan from it. Peter considered this a casus belli and prepared for open warfare against Denmark. In June 1762, 40,000 Russian troops assembled in Pomerania under General Pyotr Rumyantsev, preparing to face 27,000 Danish troops under the French general Count St. Germain in case the Russian–Danish freedom conference (scheduled for 1 July 1762 in Berlin under the patronage of Frederick II) failed to resolve the issue. However, shortly before the conference, Peter lost his throne () and the conference did not occur. The issue of Schleswig remained unresolved. Peter was accused of planning an unpatriotic war. While historically Peter's planned war against Denmark was seen as a political failure, recent scholarship has portrayed it as part of a pragmatic plan to secure his Holstein-Gottorp duchy and to expand the common Holstein-Russian power northward and westwards. Peter believed gaining territory and influence in Denmark and Northern Germany was more useful to Russia than taking East Prussia. Equally, he thought that friendship with Prussia and with Britain, following its triumph in the Seven Years War, could offer more to aid his plans than alliance
