H.M.T. Empress of Britain

The Empress of Britain was one of the ships which took troops to India in 1917 (see Edwin Northcote Dean).

The Empress of Britain in camouflage being used as a troop ship in WW1.
This photo appears to show the ship listing and may well have been taken after she had collided with a French ship in 1915.
