HMS Malvernian. HMS Malvernian was an Ellerman Lines cargo steamship that was built in 1937. In January 1941 she was converted into an ocean boarding vessel. That July she sank after a German air attack crippled her in the Atlantic Ocean.

This was the second Ellerman Lines ship called Malvernian. The first was built in 1924 as City of Kobe, renamed Malvernian later that year and changed back to City of Kobe in 1927. A mine sank City of Kobe in 1939.

Building
William Gray & Company built Malvernian in its West Hartlepool yard. She was launched on 25 February 1937 and made her sea trials on 3 June, but was not completed until that September. Her registered length was , her beam was , her depth was , and her tonnages were  and .

Malvernian had one screw. Gray's Central Marine Engineering Works built her engines. Her main engine was a steam triple expansion engine. It was supplemented by a Bauer-Wach low-pressure exhaust steam turbine, which ran on exhaust steam from the low pressure cylinder of her piston engine. Via double reduction gearing and a Föttinger fluid coupling the turbine drove the same propeller shaft as her piston engine. Between them the two engines were rated at 606 NHP and gave her a speed of .

In September 1937 Gray delivered Malvernian to the Ellerman & Papayanni Lines subsidiary of Ellerman Lines. Over the next two years Gray built three sister ships for Ellerman & Papayanni Lines: Belgravian in 1937, Ionian in 1938 and  in 1939–40.

Second World War
In the Second World War Malvernian at first continued in merchant trade. She sailed in convoys between Gibraltar and Liverpool until May 1940. In July 1940 Malvernian crossed the Atlantic to Montreal, and in August she returned in Convoy HX 62. Later that month she sailed from the Firth of Forth to Hull, and in January and February 1941 she sailed from the Firth of Forth to Oban.

In January 1941 the Admiralty requisitioned Malvernian for conversion into an ocean boarding vessel. She was armed with two 6-inch guns and one anti-aircraft 12-pounder gun. She was commissioned as HMS Malvernian with the pennant number F 102.

On 29 May 1941 HMS Malvernian intercepted and captured the  in the Bay of Biscay. Malvernian sent a prize crew aboard, which took August Wriedt to St John's, Newfoundland.

On 1 July 1941 Luftwaffe bombed Malvernian in the North Atlantic, killing four officers and 20 ratings, wounding two officers and setting her afire. Survivors abandoned ship in four lifeboats, but Malvernian remained afloat and adrift until 19 July.

The sloop  searched for survivors, found one lifeboat and rescued its 57 occupants. Kriegsmarine minesweepers found another lifeboat and captured its occupants.

The remaining two lifeboats reached Spain independently. One, carrying Malvernians commander, Cdr JWB Robertson, RNR and 31 of his crew and reached A Coruña in  on 21 July. The other, carrying 21 survivors, reached Vigo on 22 July.
