Construction and commissioning[edit]

Heartseasewas originally to have been named HMSPansy,but the name was changed prior to her launch.[2]She was ordered on 19 September 1939 andlaid downat the yards ofHarland and Wolff,Belfast,Northern Ireland, on 14 November 1939. She waslaunchedon 20 April 1940 andcommissionedinto service on 20 April 1940.[3]

Wartime service[edit]

Convoy escort[edit]

Heartseasespent most of her early career escorting convoys through British waters. On 22 September 1940 she picked up 31 survivors from the Norwegian merchantSSSimlawhich had been torpedoed and sunk by the GermanU-boatU-100west of Ireland.[3]On 15 October she rescued nine survivors from the British merchantSSThistlegarthwhich had been sunk byU-10345 nautical miles (83 km) west-north-west ofRockall.[3]She was then called to the assistance of the inboundConvoy SC 7,which had come under attack from a U-boatwolfpackand was sustaining heavy losses. On arrivalHeartseasewas assigned to escort the damagedSSCarsbreckinto port.[4]On 23 December she collided with theHunt-classdestroyerHMSTetcottin theIrish Sea.Both ships were saved and towed into port. A subsequent enquiry placed the blame on the captain ofHeartsease.[5]

American service[edit]

She was transferred to the US Navy on 3 April 1942 with Lt. Christopher Sylvanus Barker Jr., USN, commanding and renamed USSCourage.[3]She patrolled the western Atlantic for most of her career as a United States ship, escorting convoys from as far north asGreenlandto as far south asArgentina.From 24 January 1945, she was stationed atIceland.She was returned to the Royal Navy on 23 August 1945, after the end of the war.[6]

Mercantile service[edit]

She was put up for disposal and was sold into civilian service on 22 July 1946. She was renamedRoskvain 1951,Douglasin 1956 and finallySeabirdin 1958.

A Norwegian crew took her to the Far East asDouglas.[7]In the latter part of 1957 a Chinese-Indonesian businessman, A.P. Lim, engaged her and her Norwegian captain to smuggle raw rubber fromSumatratoJohoron theMalay Peninsula[8]and later to Singapore.[9]Lim's client was thePRRI( "Revolutionary Government of the Republic of Indonesia" ) right-wing rebel movement,[8]which was smuggling rubber out of Sumatra to fund its rebellion against the Indonesian government of PresidentSukarno.

Early in 1958 Indonesian forces defeated the PRRI in its main strongholds and ports on Sumatra, reducing its rebellion to a residual guerilla war. However, the PRRI was allied with thePermestarebel movement inNorth Sulawesi,which was supported byTaiwan.In December 1958Douglas,now renamedSeabird,smuggled a cargo of small arms, ammunition andM20 recoilless riflesfrom Taiwan[10]toBolaang Bayon the coast ofMinahasa.[11]There she began to load a cargo ofcopra,[11]which Permesta was smuggling out of Minahasa to fund its rebellion. However, before she could start her voyage theIndonesian Air ForcefoundSeabirdand sank her.[11]

Seabirdwas announced missing in December 1958[3]and a month later she was declared lost in theCelebes Sea,with the cause of her loss officially declared as "unknown".[12]
