Under the terms of the Armistice, the German High Seas Fleet went into internment at the Royal Navy's base at Scapa Flow – in Operation ZZ, 60 Allied battleships escorted 11 battleships, 5 battlecruisers, 8 cruisers and 48 destroyers of the High Seas Fleet into captivity. At 11:00 on 20 November 1918 King George V, Queen Mary and the Prince of Wales embarked in and, preceded by the Verdun, steamed through the fleet.
Verdun was selected to carry the Unknown Warrior across the English Channel because her name would be a tribute to the French people and the endurance of their armies at Verdun in 1916. On 10 November 1920, Verdun berthed at the Quai Carnot at Boulogne-sur-Mer. The coffin of the Unknown Warrior arrived on a French military wagon in a procession of a thousand local schoolchildren and a whole division of French soldiers and marines. Marshal Foch made a speech on the dockside before the White Ensign was lowered to half mast while the coffin was carried up the gangplank and piped aboard with an admiral's salute. The coffin was laid on the quarterdeck and covered with wreaths of white flowers, some so large that it took four soldiers to lift one. Shortly before noon, Verdun moved away from the quay as sailors fired a rifle salute along with the big guns of the French forts. An escort of six battleships accompanied Verdun through the mist to Dover where a 19-gun salute was fired from Dover Castle. She tied up at Admiralty Pier where General Sir John Longley supervised the six high-ranking officers from the three Armed Services who bore the coffin ashore. From Dover Marine Station the Unknown Warrior was taken by train to London for burial the following day at Westminster Abbey.
Second World War
Verdun received a Le Cheminant deck watch from the Royal Observatory on 13 August 1927. She went into reserve at Rosyth as part of the 9th Destroyer Flotilla until September 1939, when she was selected for conversion into an anti-aircraft escort at Chatham Dockyard. She was rearmed and her pennant number changed from D93 to L93 on completion in May 1940. She operated as a convoy escort out of Rosyth and in the North Sea, being damaged by a bomb on 1 November 1940 that killed 11 men, including her captain. She was repaired at Harwich and spent the rest of the war escorting convoys along the east coast. In November 1941, she was in sustained action against an attack by German E-boats; three British merchant ships were sunk in the engagement. From February to April 1942 she formed part of the escort screen for heavy units of the Home Fleet that were supporting the Arctic convoys. After the "Warship Week" National Savings campaign in March 1942, Verdun was adopted by the seaside town of Hoylake in Cheshire.
