Invasion of Palawan - Aftermath

Aftermath

Casualties on Palawan were unbalanced. U.S. Army forces lost 12 killed and 56 wounded, while Japanese dead numbered almost 900 and another 140 wounded, which were approximately ½ of the Palawan garrison.

Mopping up activities on Palawan lasted until late April, when the remaining Japanese simply withdrew farther into the trackless mountain jungles of Palawan—a pattern that repeated during all of the major operations in the southern Philippines—after which many were stalked and killed by U.S. troops and Filipino guerrillas.

Meanwhile, airfield construction began almost immediately on Palawan. Although marshy soil conditions slowed the engineers' progress, American fighter planes were using the Puerto Princesa airstrip by late March 1945. Construction of an all-weather runway for heavy bombers came too late to support Eichelberger's next operation, but it subsequently was used to interdict Japanese supply lines in the South China Sea and support the Borneo operations that began in May 1945.
