Claret was the code name given to operations conducted from about July 1964 until July 1966 from East Malaysia (Sarawak and Sabah) across the border in Indonesian Kalimantan during the Indonesia–Malaysia confrontation. They were instigated by the Director of Borneo Operations (DOBOPS) Major General Walter Walker with the agreement of the British and Malaysian governments. Their purpose was to seize the initiative and put the Indonesians on the defensive instead of allowing Indonesian forces to be safely based in Kalimantan and attack when and where they chose. However, it was important not to cause the Indonesians to lose face and possibly escalate the conflict, or to enable Indonesia to present evidence of 'imperialist aggression', so Claret operations were highly classified and never publicised, although it seems that some British journalists were aware of what transpired. British casualties on Claret operations were publicly reported as being in East Malaysia.
