British India Steam Navigation Company ("BI") was formed in 1856 as the Calcutta and Burmah Steam Navigation Company.

History

The Calcutta and Burmah Steam Navigation Company had been formed out of Mackinnon, Mackenzie & Co, a trading partnership of the

P&O group of companies in 1914 through a complex amalgamation, but continued with its own identity and organisation for another nearly 60 years until 1972, when it was entirely absorbed into P&O. P&O was eventually sold to Emirati logistics company DP World

in 2006.

Fleet and routes

As one of the largest shipowners of all time, the company owned more than 500 ships and managed 150 more for other owners. At its height in 1922, BI had more than 160 ships in the fleet, many built on

Java, Thailand, Japan, Persian Gulf, East Africa and South Africa

. BI had a long history of service to the British and Indian governments through trooping and other military contracts. In the last decade of its operational existence BI carried thousands of school children on educational cruises.

Mantola was sunk in February 1917 by a torpedo from a German submarine off the coast of Ireland with a substantial cargo of silver bullion.

The cargo ship

silver bullion, pig iron and tea, which was sunk at great depth by the German submarine U-101 in February 1941 some 300 nautical miles (560 km; 350 mi) southwest of Galway Bay, Ireland, carried the richest cargo of any sunken ship in world history.^[1]

Some of the company's better known passenger ships included Rajula, Dunera, Scindia, Sirdhana, Leicestershire, Dwarka, Dumra, the sister ships Kampala and Karanja, and Kenya and Uganda, and Dara, which was sunk by a terrorist bomb in 1961.
