Operation Lancer

Operation Lancer was a military operation by Dutch and Australian troops on Timor during World War Two.

Lancer Force was the name of Australian troops used to replace Sparrow Force.

Around 60 men from the KNIL were to be inserted onto Timor by the Australian navy to undertake guerilla warfare against the Japanese. Australian ships were constantly attacked by Japanese planes and on 1 December 1942 HMAS Armidale (J240) was sunk with heavy loss of life; most of the survivors died.
