Revision 4


1914:
Sunderland, England. Laid down at Sunderland Shipbuilding as an "Insect-class" gunboat to counter Austro-Hungarian monitors on the River Danube.

9 October 1915:
Launched, named and numbered HMS MOTH (T69).

5 January 1916:
Completed and registered in the Royal Navy.

1916-1917: First World War:
HMS MOTH and sister gunboats HMS MANTIS, HMS TARANTULA and HMS GNAT are transported by ship to Abadan, Persia (now Iran), terminus of the Anglo-Persian Oil Company’s (now BP) pipeline oil refinery, then the largest in the world. From Abadan, the gunboats are sent to reinforce the Royal Navy’s flotilla on the Tigris River near Baghdad during the British Empire's second campaign in Mesopotamia against the Ottoman Empire, an ally of Germany.

1918-1919: Russian Revolution:
HMS MOTH participates in actions in Northern Russia with sister ships HMS CRICKET, HMS COCKCHAFER and HMS MANTIS in support of White Russian forces against the Communist Bolsheviks.

17 January 1920:
HMS MOTH departs Chatham, England for China with HMS CRICKET, HMS COCKCHAFER, HMS MANTIS and HMS SCARAB escorted by cruiser HMS COLOMBO and sloops HMS BLUEBELL, HMS CORNFLOWER, HMS MAGNOLIA and probably HMS HOLLYHOCK. The flat-bottomed river gunboats are ill-suited for open sea service and roll in high seas. The escorts provide towing in bad weather and refuel the gunboats on the longer legs of the journey that are beyond the gunboats' fuel capacity. That Spring, after steaming through the Atlantic, Mediterranean, Suez Canal, Indian and Pacific Oceans, the little ships arrive in Hong Kong.

1929:
Yangtse River, China. At an unknown date this year, HMS MOTH strikes a submerged rock and is damaged.

17 May 1932 - January 1934:
LtCdr John M. Rodgers' HMS MOTH is in China.

7 July 1937: The Marco Polo Bridge (The"First China Incident") Incident:
Hun River, Lukuokiao (Peking), China. The Japanese discover a soldier missing after night maneuvers at the bridge and assume the Chinese captured him. They demand entry to a Beijing suburb to look for him, but the Chinese refuse. The Japanese then shell the city and an undeclared war begins. [1]

October 1938:
One of HMS MOTH's original 12-lb guns is replaced by a 3-inch/45 HA gun and her Maxim machine guns are replaced by eight Lewis machine guns.

12-21 October 1938:
Ta-Ya (Bias Bay), 35 miles NE of Hong Kong. At dawn, LtGen Furusho Motoo’s 21st Army, supported by the China Area Fleet’s Fifth Fleet and Formosa-based and carrier-based Navy air units, makes a surprise landing. Thereafter, Japanese forces continue their advance with little or no resistance. By 21 October, they capture Canton. The operation isolates Hong Kong and Macao.

10 June 1940:
Lt Cdr H. R. White's HMS MOTH is at Hong Kong under command of the Commodore, Hong Kong. HMS MOTH is assigned to patrol the West River (Si Kiang).

1 January 1941:
Royal Navy Reserve Temporary Lt J. Douglas' HMS MOTH is assigned to patrol the West River.

1 May to 4 June 1941:
Repaired at Hong Kong.

8 December 1941:
The Japanese open their offensive on Hong Kong by moving troops across the frontier of Hong Kong's New Territories. Twelve Tachikawa Ki-36 "Ida" Army bombers of the 45th Sentai escorted by nine Ki-27 "Nate" fighters also attack Kai Tak airport on Kowloon. All five of the token RAF aircraft (2 "Walrus" amphibians and 3 Vickers "Vildebeeste" torpedo bombers) stationed at Kai Tak are quickly either damaged or destroyed as are numerous light trainers and civilian cargo planes. In the harbor, PanAm’s visiting Sikorsky S-42B flying boat "Hong Kong Clipper" is bombed, set afire and sinks.

11 December 1941:
Port of Hong Kong. Sometime prior to the outbreak of the war, HMS MOTH had been drydocked in Hong Kong Navy Yard to repair her bottom plating . As most of the yard personnel had been mobilized, the work was never completed. Most of her armament was landed and the crew sent ashore to defend the city. HMS MOTH and auxiliary minesweeper HMS MARGARET probably sink when the drydock they are in is intentionally scuttled.

24 December 1941:
Japanese troops capture the navy yard.

25 December 1941: The Fall of Hong Kong:
MajGen Christopher M. Maltby, British Indian Army, advises Hong Kong's Governor Sir Mark A. Young to surrender the outnumbered British garrison because of lack of food and water. At 1800, in Japanese headquarters set up in the fashionable Peninsula Hotel on Kowloon, Young surrenders the Crown Colony to LtGen Sakai Takashi, CG, 23rd Army. That night, nearly 6,500 British and Commonwealth troops go into Japanese captivity.

Early February 1942:
The hull of HMS MOTH is refloated and attached alongside a pier in navy yard. She undergoes repairs at the IJN's No. 2 Repair Facility in Hong Kong.

27 September 1942:
LISBON MARU departs Hong Kong for Shanghai with 1,816 British Commonwealth prisoners of war (POWs) and about 700 Japanese troops aboard.

1 October 1942:
China coast. Six miles from Tung Fusham Island. LtCdr (later Cdr) Rob R. McGregor's (USNA ’29) USS GROUPER (SS-214) fires six Mark XIV torpedoes at LISBON MARU. Five torpedoes miss, but one hits her stern. As the ship slowly settles, the Japanese evacuate their troops, but the guards batten down the holds, trapping the POWs. Some break through the hatches, only to be gunned down. Still, many POWs get off the ship and make it to land, but are soon recaptured. LISBON MARU finally sinks at 29-57N, 122-56N. 820 POWs are lost including at least one former crewman of HMS MOTH.

Authors' Notes:
[1] "Lukuokiao" and "Beijing" are examples of different romanization systems. Following the older convention, we used the city name "Peking".

[2] Lt Haba Akira’s name can also be read as Haneba Naoshi.

[3] The bombers were probably 75-mm cannon-equipped B-25Gs, since they left several unusually large craters behind.

Thanks for assistance go to Dr. Higuchi Tatsuhiro of Japan and Mr. Gilbert Casse of France.
