Siege of Port Arthur
The port eventually fell 2 January 1905 after a long train of battles on land and sea during which the Japanese occupied the whole of the Korean Peninsula, split the Russian Army, devastated the Russian Fleet, and cut off the source of supplies on the railway from Harbin, culminating in the bloody battle known as the Siege of Port Arthur (June–January; some sources place the siege start in late July, a technical difference due to definitions).
