which then provided Force 136 with support and manpower. This first intelligence network collapsed, however, when many of its leaders, including Lim Bo Seng, were caught, tortured and killed by the Japanese "Kenpeitai" in June 1944. On 16 December 1944, a second intelligence network, comprising five Malay SOE agents and two British liaison officers, Major Peter G. Dobree and Captain Clifford, was parachuted into Padang Cermin, near Temenggor Lake Dam in Hulu Perak under the codename Operation Hebrides. Its main objective was to set up wireless communications between Malaya and Force 136 headquarters in Kandy, British Ceylon, after the MPAJA's failure to do so.
