On 5 April "Hero" escorted the battlecruiser as she covered the minelayers preparing to implement Operation Wilfred, an operation to lay mines in the Vestfjord to prevent the transport of Swedish iron ore from Narvik to Germany. The ship and her sister pretended to lay a minefield off Bud, Norway on 8 April and reported its location to the Norwegians. "Hero" and the destroyer streamed their TSDS minesweeping gear in advance of the battleship and her escort as they steamed up the Vestfjord to engage the remaining German destroyers at Narvik on 13 April. The ship and four other British destroyers pursued the remaining German ships into the Rombaksfjorden (the easternmost branch of the Ofotfjord), east of Narvik, where the lack of ammunition had forced the German ships to retreat. Most of the German destroyers had scuttled and beached themselves at the head of the fjord, but the scuttling charges on had failed to detonate properly and she was boarded by a small party from "Hero". They found nothing of any significance as she'd been abandoned by her crew and the destroyer put a torpedo into her to prevent any salvage.
