By the concluding months of 1964, the conflict once again appeared to have reached a stalemate, with Commonwealth forces having placed in check for the moment Indonesia's campaign of infiltrations into Borneo, and more recently, the Malaysian Peninsula. However, the fragile equilibrium looked likely to change once again in December 1964 when Commonwealth intelligence began reporting a build-up of Indonesian infiltration forces in Kalimantan opposite Kuching, which suggested the possibility of an escalation in hostilities. Two additional British battalions were subsequently deployed to Borneo. Meanwhile, due to the landings in Malaysia and Indonesia's continued troop build-up, Australia and New Zealand also agreed to begin deploying combat forces to Borneo in early 1965.
