The only Allied military forces at Tulagi were 24 commandos from the Australian Army's 2/1st Independent Company, under Captain A. L. Goode, and about 25 personnel from 11 Squadron RAAF, under F/O R. B. Peagam, operating a seaplane base on nearby Gavutu-Tanambogo with four PBY Catalina maritime patrol aircraft. Three Allied coastwatchers were also located nearby, on Guadalcanal island. The task of the coastwatchers was to report on any enemy movements, or suspicious activity, that they observed in the vicinity of their stations. In the belief that it might prevent them being executed for espionage, all of the coastwatchers were commissioned as Royal Australian Naval Volunteer Reserve officers, and they were directed by Lieutenant Commander Eric Feldt, who was located at Townsville in Australia.
