The Borneo Campaign was a series of military operations during World War II, primarily conducted between 1945 and 1946. It aimed to liberate the island of Borneo from Japanese occupation. Allied forces, mainly from Australia and Britain, launched attacks to reclaim strategic locations and disrupt Japanese supply lines. The campaign involved several land and amphibious assaults, with significant battles occurring in areas like Tarakan and Balikpapan. Ultimately, the successful operations contributed to the overall defeat of Japan in the Pacific theater and helped secure the region for post-war reconstruction and governance.
