Gilbert Roberts (Royal Navy Officer)

Gilbert Howland Roberts CBE (11 Oct 1900 – 22 Jan 1986) was an officer in the Royal Navy. From 1942 to 1945, Captain Roberts operated a naval wargaming unit based in Liverpool called the Western Approaches Tactical Unit (WATU). This unit developed anti-submarine tactics to defend trans-Atlantic merchant convoys from German submarines.

Early life

Gilbert Roberts was the second son of Sir Howland Roberts, 12th Baron Glassenbury of Kent and 5th Baronet of Britfieldstown in Cork.

Military career

Roberts joined the Royal Navy as a cadet in September 1913, a month shy of his thirteenth birthday. His first posting was ''HMS Hibernia''.

From 1935 to 1937, Roberts studied at the Portsmouth Tactical School. There, he discovered naval wargaming, and became an enthusiastic practitioner. Like many wargaming enthusiasts of his time, he developed his own rules, based mainly on the wargames of Fred T. Jane.

Roberts was given command of the destroyer HMS ''Fearless'' in autumn 1937. In December, the ''Fearless'' joined a flotilla to patrol the Spanish coast (during Spain's civil war). In late 1938 he developed tuberculosis. He was deemed medically unfit and retired on 28 October 1938.

Roberts convalesced at the King Edward VII Sanatorium in Midhurst until April 1939.

On 1 January 1942 Roberts met with Admiral Cecil Usborne in London. Usborne ordered Roberts to report to the Western Approaches headquarters in Liverpool, where he was to establish the Western Approaches Tactical Unit. This organisation developed tactics by which shipping convoys in the Atlantic could defend themselves from German submarine attacks. Through the use of wargames, performed by a combination of WRENs and Royal Navy officers, he studied the reports of convoy escorts, devised defensive tactics, and trained escort commanders in their use.

In 1944, Roberts was tasked with planning the anti-submarine operations that supported Operation Overlord. These proved highly effective.

According to his colleagues and staffers, Roberts was a difficult man to work for. He was noted for being pushy, stubborn, and intolerant of disagreement. Nevertheless, he was liked and respected by his staff. It is suggested his abrasive personality was aggravated by his illness.

In 1945, Robert visited the Germans' U-boat headquarters in Flensburg. On the wall, he found a portrait of himself, taken from a 1944 article from ''Illustrated'' magazine . Allegedly, it bore the caption: "This is your enemy, Captain Roberts, Director of Anti U-boat Tactics",Williams (1979) though Roberts didn't mention this caption in his memoirs. He did autograph the portrait for the pleasure of the Germans present.
