Two weeks after the Pearl Harbor attack, Japan accelerated its plans to invade the Dutch East Indies for vital oil resources, essential for its war efforts. As Japanese forces swiftly advanced in the Philippines, they captured strategic locations, including Mindanao and Davao, while Allied defenses crumbled. In late December 1941, Japan launched further assaults in Malaya, isolating Singapore and diminishing Allied naval power. By January 1942, Japanese forces targeted Balikpapan, a crucial oil hub in Borneo. The Dutch, determined to defend their territory, prepared for a guerrilla campaign and attempted to sabotage oil facilities. However, the Japanese invasion fleet approached Balikpapan on January 21, 1942. Despite Allied air attacks and submarine efforts, the Japanese landed on January 24, marking a significant step in their campaign to secure the East Indies, while the Allies faced overwhelming challenges and dwindling resources.
In the early hours of January 24, 1942, Talbot's destroyers stealthily approached the anchored Japanese fleet, illuminated by burning oil facilities. Utilizing torpedoes for surprise attacks, they struck swiftly, sinking several transports, including Sumanoura Maru. Despite their efforts, many torpedoes missed, and the Japanese fleet sustained fewer losses than expected. By dawn, the Allies had achieved a tactical victory, but nine of twelve transports survived, allowing the Japanese advance into the Dutch East Indies to continue. In February, an Allied strike force was formed, but they faced devastating air assaults, retreating to Surabaya after suffering heavy damage without losing ships.
