Dalton Pass, also called Balete Pass, is a zigzag road and mountain pass that joins the provinces of Nueva Ecija and Nueva Vizcaya, in central Luzon island of the Philippines. It is part of Cagayan Valley Road segment of Pan-Philippine Highway (Maharlika Highway). Geography The summit of the mountain pass is at around in elevation, located where the Caraballo Sur (mountain range) and the Sierra Madre (mountain range) meet. The headwaters of the Digdig River originate just south of the pass. Balete Ridge starts two miles to the west-northwest of the pass, with a high point at Mt. Imugan (5,580 feet), and extends nine miles to the east-southeast, where it ends at Mt. Kabuto (4,600 feet ). Dalton Pass is a gateway to the Cagayan Valley, and the Ifugao Rice Terraces. Battle of Balete Pass The Japanese strategy during the Battle of Luzon was to fight a delaying retreat from Baguio to Bayombong, and then to a final defensive position in Kiangan, Ifugao. The pass was the only access between Central Luzon and the Cagayan Valley, and was the scene of much bloody fighting in the Battle of Luzon, during the final stages of World War II. Balete Pass lies along Highway 5 from San Jose City and Santa Fe, and became a defensive position for Tomoyuki Yamashita's forces. A similar defensive battle was fought at Salacsac Pass, along the Villa Verde Trail joining San Nicolas and Santa Fe. Japanese Gen. Yoshiharu Iwanaka's 2nd Tank Division fought a retreating battle from San Jose to Dupax, before confronting the American 32nd Division, under the command of Maj. Gen. William H. Gill, at Salacsac Pass in early March 1945. That left the Japanese 10th Division, under the command of Lt. Gen. Yasuyuki Okamoto, to confront the American 25th Division, under the command of Maj. Gen. Charles L. Mullins, at Balete Pass. According to Ogawa, "When Balete was about to be captured, those unable to move were left to die after much pain and agony. Some of the more fortunate were given potassium cyanide or hand grenades to dispose of themselves quickly." The Americans took the Balete area on 31 May 1945. The Japanese lost 7,750 at Balete Pass, and 5,410 at Salacsac Pass. The Battle of Balete Pass incurred the death of 685, and the wounding of 2,090, 25th Division American soldiers between 21 Feb. and 31 May 1945. The Battle of
