HMS Whitehall, pennant number D94, later I94, was a Modified W-class destroyer of the British Royal Navy that saw service in the Second World War.

She then remained in commission as the fleet mobilised because of deteriorating diplomatic relations between the United Kingdom and Nazi Germany, and received orders to proceed to Rosyth, Scotland, in the event of war and report for duty there with the 15th Destroyer Flotilla.

[1] After the United Kingdom entered the Second World War on 3 September 1939, Whitehall took aboard stores and her wartime complement and proceeded to Rosyth for her assignment with the 15th Destroyer Flotilla.

[1] After spending the first half of 1941 on North Atlantic convoy duty without any significant incidents, Whitehall was selected in June 1941 to carry out trials of a new weapon, the Five Wide Virgins,[8] a mortar designed by John I. Thornycroft & Company to fire depth charges ahead of a ship attacking an enemy submarine.

She joined Witch and the Royal Netherlands Navy light cruiser HNLMS Jacob van Heemskerck in escorting Convoy WS 10X from Liverpool to the Clyde on 15 August 1941.

On 20 March, Whitehall, Active, Anthony, Blankney, Croome, Duncan, Exmoor, Laforey, and Wishart again departed Gibraltar as escort for Argus and Eagle as the two carriers again delivered aircraft to Malta in Operation Picket I.

The submarines sank two of the convoy's merchant ships that day, and Whitehall, Hesperus, and the corvette Clematis joined forces to drive off U-359 and U-383.

[1] In October 1943, Whitehall participated in Operation Alacrity, the establishment of air and refuelling bases in the Azores, escorting convoys carrying men, equipment, and supplies to the islands.

On 20 December 1943, she set out from Loch Ewe with the destroyer HMS Wrestler, the corvettes Honeysuckle and Oxlip, and the minesweeper Gleaner as the escort for Convoy JW 55B; after the German battleship Scharnhorst put to sea to threaten the convoy, destroyers of the Home Fleet joined the escort on 25 December.

On 31 December, Whitehall, Wrestler, Honeysuckle, Oxlip, and the corvette Rhododendron departed the Kola Inlet as the escort for Convoy RA 55B.

[1] On 22 January 1944, Whitehall, Oxlip, the destroyer Westcott, the sloop Cygnet, and the minesweeper Seagull departed Loch Ewe escorting Convoy JW 56B to the Soviet Union.

Six German submarines of Wolfpack Werewolf attacked on 30 January, sinking the destroyer Hardy but failing to press home attacks against the convoy's merchant ships, and in response Whitehall and the destroyer Meteor depth-charged and sank the German submarine U-314 that day in the Barents Sea southeast of Bear Island at 73°41′00″N 024°30′00″E / 73.68333°N 24.50000°E / 73.68333; 24.50000 (U-314 sunk) with the loss of her entire crew of 49.

On 27 March 1944, she joined Honeysuckle, Westcott, Wrestler, and the corvettes Bluebell and Lotus as the escort for Convoy JW 58, departing Loch Ewe that day.

During the passage, she was part of a force of 15 destroyers and Royal Canadian Navy frigates screening Activity, Diadem, and the escort aircraft carrier Fencer.

On 3 May, Whitehall, Boadicea, Diadem, Fencer, Walker, and the destroyers Ulysses, Verulam, and Virago detached from the force and proceeded independently to the United Kingdom.

[1] Upon arrival in the United Kingdom, Whitehall was reassigned to North Atlantic convoy duty, but later in May 1944 was selected to participate in Operation Neptune, the assault phase of the upcoming Allied invasion of Normandy, scheduled for early June 1944.

On 15 August 1944, she departed the United Kingdom as part of the close escort for Convoy JW 59 with Bluebell, Cygnet, Honeysuckle, Oxlip, the frigate HMS Loch Dunvegan, and the corvettes Camellia and Charlock.

On 2 September 1944, she shared credit with Keppel, Mermaid, Peacock, and a Fairey Swordfish aircraft of Fleet Air Arm No.

[1][15] After the completion of repairs in March 1945, Whitehall was assigned to escort duty in the waters around Great Britain, which she continued until the surrender of Germany in early May 1945.

[2] Placed on the disposal list after the 15 August 1945 surrender of Japan, she was sold in October 1945 to the British Iron & Steel Corporation (BISCO), which allocated her for scrapping to Thos.
