The SS Greatham was built in 1890 by William Gray & Co. Ltd of West Hartlepool, Yard number 382. SHe was launched on the 8/3/1890 as the SS Bussorah and owned/operated by T Appleby & Co until in 1891 she was renamed the SS Greatham and new SS Greatham aground Isle of Manoperators, Coombes, Marshall & Co took over.
The Greatham was a 2338grt 290ft defensively armed British Merchant Ship.

On the 22nd January 1918 the SS Greatham was steaming in convoy, on passage from Grimsby to Blaye, Bordeaux France, with a cargo of coal when she was sited by Oberleutnant Thomas Bieber on UB-31 approximately 3 miles SE of Dartmouth. UB-31 promptly torpedoed the Greatham and she sank with the loss of 7 crew.

There has been some confusion over the identitiy of the Greatham as she has been confused with the SS Elsa who lays within a mile of the Greatham. However Steve Macay and a group of divers did some extensive surveying of these 2 sites (within 1nm of each other) in the mid 2000's and identified the 2 sites correctly based on engineering information and hull damage. For the Elsa see:

The Greatahm now lays in 47m of water and is pretty much intact with some damage ffwd of midships. She is generally in clean water and usually reports 5m+ viz on her. A great technical dive!
