In 18 months service
Heliotrope escorted 18 North Atlantic, eight
Gibraltar and four South Atlantic convoys, assisting in the safe passage of over 750 ships.
She was involved in four major convoy battles: In October 1940
Heliotrope was part of the escort for
HX 79, which was attacked by a U-boat
"wolfpack", losing 12 ships sunk. In May 1941 she joined
HX 126 which saw nine ships sunk and one U-boat damaged. In August 1941 she joined
SL 81 which saw five ships sunk, while one U-boat was destroyed and two damaged In October 1941 she was with
HG 75 which saw four ships and one escort sunk, and one U-boat destroyed.
Heliotrope was transferred to the U.S. Navy at
Hull, England, on 24 March 1942, one of a group of corvettes transferred to the
U.S. Navy under reverse
Lend-Lease. She was
commissioned as USS
Surprise the same day. She was delivered with British
radars and armament installed, and over the course of her U.S. Navy service was gradually converted to U.S. standards. The 4-inch (102 mm) gun was mounted forward, the 3-inch (76 mm) gun aft.
Surprise sailed from Lisahally,
County Londonderry, Northern Ireland on 24 April 1942 to escort a
convoy to
Boston, Massachusetts. After an overhaul, she proceeded south and for the remainder of 1942 escorted convoys in the
Caribbean Sea, principally between
Trinidad and
Guantanamo Bay, Cuba. In January 1943, she extended her range into the South Atlantic and, into 1944, performed escort runs between Trinidad and
Recife, Brazil.
Surprise then returned to the United States. In May 1944, she returned to the North Atlantic and, until after the end of World War II in Europe in May 1945, rotated between
Newfoundland, Greenland, and
Iceland convoy runs and weather patrol duty.
Surprise was
decommissioned on 20 August 1945 at
Chatham, England, returned to the Royal Navy on 26 August, and struck from the
Naval Vessel Register on 17 September.
She was transferred to China in 1947, and, after a period of mercantile service, she was taken into the
People's Liberation Army Navy service as
Linyi after converting to a
gunboat, and finally retired in 1972.
