				Russia's tightening influence in Manchuria and Korea led to tensions with Japan. With the Russians also building the Trans-Siberian Railway to connect their European heartland to the Far East, the Japanese decided they had to act quickly to prevent total Russian domination of the region. On February 8, the Japanese launched a surprise torpedo attack on the Russian Pacific Fleet at Port Arthur, triggering war.
