The RMS Saxon was a Royal Mail Ship that went into service with Castle Line (and its successor, the Union-Castle Line) in 1900, on the passenger and mail service run between Britain and South Africa.

[1] After the Boer War, the Saxon was one of nine ships that made up the Southampton-Cape Town Mail Run.

[2] In May 1901, the High Commissioner of South Africa, Lord Alfred Milner, traveled aboard the Saxon on his way back to Southampton, England.

[4] During World War I, the Saxon was requisitioned by the government and served as a troopship in the Mediterranean and the North Atlantic, carrying American troops from New York to France.

The Saxon suffered a serious fire in 1921 and had to be escorted to Freetown, Sierra Leone, where another ship picked up her passengers and mail.
