What are the directions, reasons, how the Russo-Japanese war ended?

The Russo-Japanese War began over the territory of Manchuria and Korea, both of these empires did not want to lose their control in the Far East. In this war, for the first time, long-range artillery began to be used, a navy manned by destroyers and battleships. The Russian government took measures for the inevitable war with the Japanese. Construction of the Siberian Railway, providing the rear with the state through the signing of peace treaties with Austria and Germany. Settlement and development of the Far Eastern lands by peasants from the central provinces of Russia. The Russian armed forces were not sufficiently prepared. The remoteness of the theater of operations from the capital, the incompetence of the commanders and outdated weapons became the reasons for the military failures of the ground forces and the navy. Port Arthur, Tsushima, Mukden, Liaoliang became a symbol of the courage of a Russian soldier and a shame for the government of a huge empire. Russia lost the southern regions of Sakhalin, control over Liaoyang, and lease rights to the South Manchurian Railway.
