sea trials,
Nizam was assigned to
Scapa Flow, where she was assigned to fleet duties, then retasked as an escort for convoys crossing the Atlantic. Following mediation between the sailors and the officers, the captain agreed to restore the original arrangements and decided not to charge the sailors, after which the watchkeepers returned to duty. When the campaign turned for the worse,
Nizam and made two evacuation runs to ferry troops from the island to Alexandria. During her time based here,
Nizam participated in
Operation Cockpit, a carrier air raid on Japanese assets in south-east Asia. On 15 August 1945,
Nizam received orders to cease hostilities; shortly after this, the ship was attacked by a Japanese fighter, which was shot down. The destroyer left for Australia on 24 September. ==Decommissioning and fate==
