Still the situation went from bad to worse. On December 1, 1879, as the imperial train was entering Moscow, it was wrecked by a mine. Alexander escaped because he had traveled in an earlier section. Three days later the "Executive Committee" issued a proclamation excusing the attempt and announcing that the czar had been condemned to death. On February 17, 1880, an explosion of dynamite in the guard room of the Winter Palace, just beneath the imperial dining-room, killed and maimed a large number of soldiers, but the imperial family escaped by a hair's breadth, as the czar had not entered the room. On the 24th of the same month Louis Melikof was placed in charge of the city of St. Petersburg, and eight days later there was an attempt upon his life. There was a panic in the capital, when a nihilist proclamation (p. 238) announced that these attempts would cease, provided the czar would renounce his autocracy and "leave the task of establishing social reforms to an assembly representing the entire Russian people."
Whatever may have been his motive, Melikof urged the czar to try what conciliation would effect. Upon his advice, a large number of exiles in Siberia were pardoned, and persons imprisoned for political offenses were released. About 2,000 students expelled from the universities were readmitted, and in several cases the death sentence pronounced against nihilists was commuted. Only two men out of the sixteen convicted of the attempt to blow up the Winter Palace, were executed. The effect of this new policy was so satisfactory, that on the 18th of August, 1880, the czar revoked the ukase of February 24, and Melikof was appointed as Minister of the Interior. He advised the czar to grant a constitution, and in February 1881, placed before Alexander a plan to effect this important change gradually. It was discussed in the Council of State. The majority approved, but a bitter opposition was manifested by the other members. The czar himself was in favor of it, but the persons with whom he came into daily contact caused him to hesitate. He told Melikof that he would give his final decision on March 12.
On that day he had not made up his mind, but on the 13th, he ordered that Melikof's scheme should become a law, and that it be published in the Official Gazette. That afternoon, as he was returning from his usual drive, and his carriage was passing between the Catherine Canal and Michael's Garden, a bomb was thrown under his carriage and (p. 239) exploded, killing or wounding a number of the guard, but Alexander was unhurt. He was hurrying to assist the wounded, when another bomb exploded near him and he was dreadfully mangled. He regained consciousness for a moment while his attendants were bearing him to the palace, but died at 3.30 P.M., without having spoken a word.
