Passage: On 4 May 1918, in the aftermath of the Finnish Civil War, Silatch arrived secretly in Kotka, Finland, to evacuate remaining members of the Finnish Red Guard. However, she was confiscated by the Finns and joined the Finnish icebreaker fleet as Ilmarinen, after the legendary hero from Kalevala. In December 1919 she was sent to Koivisto to assist three Finnish torpedo boats, C1, C2 and C3 that had been surrounded by ice some thick. The 150-ton torpedo boats had participated in the British campaign in the Baltic, and Admiral Walter Cowan had demanded that the Finnish squadron patrolling the area had to stay until the British forces had withdrawn. Despite the efforts of Ilmarinen, the weak-hulled torpedo boats were crushed by the ice, and the newly founded Finnish Navy lost one fifth of its ships. After the winter of 1919 Ilmarinen was laid up until she was returned to the Soviet Union according to the Treaty of Tartu. In turn the Soviets gave back the Finnish icebreaker Avance. The name Ilmarinen was later given to a Finnish coastal defence ship launched in 1931.

question:
Passage: The game began shortly after 4 p.m. with Greg Maddux pitching for Atlanta and Masato Yoshii starting for the Mets. The Mets took an early 2–0 lead in the bottom of the first inning as John Olerud hit his second home run in as many days with Rickey Henderson on first. The lead lasted into the fourth inning, when Atlanta struck back with consecutive doubles by Bret Boone and Chipper Jones, eventually knotting the score at 2–2 when Brian Jordan singled home Jones. Mets Manager Bobby Valentine was immediately prompted to remove Yoshii from the game in favor of Orel Hershiser, which began a run on pitching changes that resulted in the Mets emptying their bullpen by game's end, relying on starter Kenny Rogers and rookie Octavio Dotel for key innings, and might have gone to Game 4's starter Rick Reed had the game progressed past the fifteenth inning. In all, the Mets used a postseason record nine pitchers in this game.
