at Scapa Flow, 25 June 1942 Acceptance trials started on 6 May; she was commissioned into the Royal Netherlands Navy service on 27 May and
Tjerk Hiddes was allocated to serve with the British Royal Navy's
7th Destroyer Flotilla in the
Eastern Fleet. At
Scapa Flow, in June and early July, she worked-up with the
Home Fleet and prepared for foreign service. In mid-July at the
Clyde, she joined the escort of military convoy WS21P from the Clyde to the Indian Ocean. During the voyage, on 5 August the convoy was augmented by eight ships of Convoy AS4, carrying equipment for the
8th Army in Egypt. On 20 August,
Tjerk Hiddes and
Nepal left the convoy, sailing to
Kilindini, in Kenya. on passage to
Majunga for the landings. The two Dutch destroyers, and
Tjerk Hiddes were deployed as screen for HMS
Illustrious. Between 18 and 24 February 1943, she was deployed with sister ship
Van Galen and cruisers and to escort a troop convoy between Fremantle and Melbourne (
Operation Pamphlet; this military convoy was carrying the
9th Australian Division, recalled from the Middle East in response to the apparent Japanese threat to Australia). On 22 March,
Tjerk Hiddes deployed with a large fleet to practice at-sea refuelling and to rendezvous with the US aircraft carrier .
Saratogas role was predominantly to act as a mentor for Commonwealth units intended for service in the western Pacific (as the
British Pacific Fleet) with the United States Navy, where these units would have to convert to use American procedures. As a part of the retraining, Commonwealth and United States naval aircraft executed attacks on Japanese oil installations. Apart from the training and the damage thus caused, it was hoped that Japanese forces would be diverted from regions where the Americans planned to take the offensive.
Tjerk Hiddes had to return prematurely to Trincomalee on 25 March, with mechanical defects, and remained under repair until June, when she returned to convoy escort duties in the Indian Ocean. In October 1944, she returned to the United Kingdom, joining the
8th Destroyer Flotilla at
Plymouth on convoy duties in the
Southwest Approaches. She moved to
Dundee for a refit from May to August 1945, by which time the war was over. ==Post war==
