Operation Lion was formed to establish an intelligence centre on central Sulawesi (called Celebes at the time).
Brandon comprised the party which left Darwin by the prahu Somoa on 24 June 1942, to land near Wotoe, 60 kilometres (37 mi) west of Malili, on Celebes.
The party was contacted by radio on 7 November 1942, however their signals were too weak to be received.
[1] On 14 December 1942, two Dutch NCO's (from the NEI Section) were in Darwin awaiting movement to LION party, but it was suspected that LION had come under Japanese control they were not dispatched.
The leader was captured; the remainder were evacuated by Catalina flying boat on 31 January 1945.
