Yemelyan Pugachev
Yemelyan Ivanovich Pugachev () (c. 1742 – ) was a Russian Cossack who led a great popular insurrection during the reign of Catherine the Great, claiming to be her late husband, Emperor Peter III. Alexander Pushkin wrote a notable history of the rebellion, "The History of Pugachev", and he recounted some of the events in his novel "The Captain's Daughter" (1836).
Peter Petrovich Dolgorukov (general, born 1777)
When war broke out with the First French Empire in 1805 he returned to Berlin to try to persuade the Prussian king to act in concert with Russia and the Austrian Empire. Before the battle of Austerlitz Napoleon sent general Anne Jean Marie René Savary to Alexander I to offer a personal meeting between Napoleon and the tsar. Alexander declined to go himself and in his place sent Dolgorukov, who was very much in favour of the war and confident the Russian troops could beat Napoleon. He was received graciously by Napoleon but responded proudly and arrogantly, rejecting all of Napoleon's proposals and presenting his own proposals brusquely. He reported back to Alexander that Napoleon was afraid of fighting the Russian army and insisted on giving battle, contrary to the opinion of Mikhail Kutuzov - Russian officers and noblemen thus later gave Dolgorukov most of the blame for the ensuing defeat. During the battle he was an infantry commander in Prince Pyotr Bagration's corps, showing great courage and repulsing the enemy attacks several times. He was sent back to Berlin on the day after the battle to induce Frederick William III of Prussia to declare war on Napoleon as soon as possible.
