We shrink from all details on this painful subject. The conspirators remained in deliberation all night. As the morning dawned, they went to the barracks of their regiments, and told the soldiers that Constantine was really their emperor, that he was marching to the capital at the head of the army from Poland, and that to take the oath to Nicholas would consequently be treason. In several instances they succeeded, and collected a considerable body of troops in the Great Izaak Square. But there they seem to have lost their senses. An insurrection which stands still, is an insurrection ruined. They were rapidly surrounded by the garrison. Terms were offered, which they neither accepted nor refused. The gallant Milarodowitch, the hero of the Russian pursuit of the French, advancing to parley with them, was brutally shot. When all hope of submission was at an end, when the day was declining, and alarm was excited for the condition of the capital during the night, artillery was brought to bear upon them; and, after some firing on both sides, the mutineers dispersed. The police were then let loose, and numerous arrests were made. In five months after, a high court was constituted for the trial of the leaders. A hundred and twenty-one were named in the act of accusation, many of them belonging to the first families, and in the highest ranks of civil and military employment. But the sentence was the reverse of sanguinary. Only five were put to death in St Petersburg, the remainder were chiefly sent to Siberia. But Siberia is now by no means the place of horrors which it once was. It is now tolerably peopled, it has been partially civilised; the soil is fertile; towns have sprung up; and, though the winter is severe, the climate is healthy. Many of the families of the exiles were suffered to accompany them; and probably, on the whole, the exchange was not a calamitous one, from the anxieties of Russian life, the pressure of narrow circumstances in Europe, and the common disappointments to which all competitors for distinction, or even for a livelihood, are exposed in the crowded and struggling population of the west, to the undisturbed existence and sufficient provision, which were to be found in the east of this almost boundless empire.
