Following the outbreak of war in 1939, the HKNVR was granted the Royal Naval Volunteer Reserve status and was renamed Hong Kong Royal Naval Volunteer Reserve (HKRNVR). Morale was low during wartime: British seamen wanted to participate in active engagements with the enemy closer to their home country, and Chinese seamen were not concerned about the far-removed European war. On 17 August 1940,
Ho Tung loaned
SS Tai Hing to the HKRNVR for the duration of the war. It replaced
Cornflower as headquarters of the force, and on 7 September,
Tai Hing was renamed HMS
Cornflower. The unit served and operated seamlessly with the Royal Navy, and was mostly used for mine warfare and patrolling. On 8 December 1941,
Japan invaded Hong Kong. At the time, the force numbered 800 men. During battle, the unit saw mass desertions. The whole crew of HMS
Perla "bolted" after the adjacent HMS
Indira was sunk. The morale worsened on 11 December, when seamen were ordered to fire upon fellow Chinese, whose junks were wrongly-accused of carrying Japanese infiltrators. The seamen also feared for the safety of their family, who had not been moved to safe houses due to the abruptness of the invasion. The fears were made worse when
Kowloon was evacuated on 13 December, leaving the fate of many on the peninsula unknown. Many seamen deserted to check on their families. On 16 December, the replacement crew of HMS
Minnie witnessed a large scale air-raid and immediately refused to serve. As a Japanese victory drew nearer, orders were sent out to have all ships in the harbour scuttled. Several HKRNVR members of the 2nd MTB Flotilla refused the order, and with their
motor torpedo boats, aided Admiral
Chan Chak in his escape to China. The Hong Kong garrison surrendered on 25 December, and was occupied by Japan until Admiral
Cecil Harcourt accepted the Japanese surrender in 1945. ==Post War==
