Flower-class corvette
On 16 August 1953, she intervened when the British mercantile freighter "Nigelock" (the former Flower-class corvette ), was seized in the Taiwan Strait by a gunboat of the Republic of China Navy enforcing Taiwan's Guanbi policy of blockading the coast of the Chinese mainland and ordered to make for Penghu. The appearance of "St Brides Bay" caused the gunboat to depart, allowing the freighter to continue on her original journey.
