"Beagle" was briefly reassigned to the 8th Escort Group before she was transferred to Plymouth Command on 11 March for escort duties. The ship was tasked to blockade the German-occupied ports in France from 12 April. The ship arrived in the Channel Islands and landed at St Helier on Jersey on 9 May 1945 and accepted the German forces' unconditional surrender. Surgeon Lieutenant Ronald McDonald and Sub Lieutenant R Milne, were met by the Harbour Master, who escorted them to his office where they together hoisted the Union Flag, before also raising it on the flagstaff of the Pomme D'Or Hotel. Her sister arrived at St Peter Port in Guernsey on the same date to accept the German surrender on that island. "Beagle" was placed in reserve fifteen days later and was approved for scrapping on 22 December. She was turned over for scrapping on 15 January 1946 at Rosyth and moved to the shipbreaking yard of Metal Industries, Limited two days later.
