Wartime History
On December 10, 1941 the Japanese Army "Tanaka Detachment" landed at Aparri in conjunction with another landing at Gonzaga. Afterwards, the Appari area was occupied by the Japanese Army and was developed as a logistic area supporting the Japanese advance. Occupied by the Japanese until late June 1945. Starting in the middle of January 1945 attacked by American until August 1945.

American mission against Aparri
January 14, 1945–August 7, 1945

In late February 1945, elements of the Japanese Army 103rd Infantry Division occupied the Aparri area including two regiments of infantry and two battalions of artillery under the command of Divisional Headquarters. Defending Japanese 14th Area Army commander General Tomoyuki Yamashita anticipated the U. S. might conduct an airborne assault in the Cagayan Valley.

By the end of February 1945, Filipino guerrillas under U. S. Army Forces in the Philippines (Northern Luzon) USAFFE-NL controlled the area to the west of Aparri. At one time U. S. Army General Krueger considered mounting an amphibious landing at Aparri in late May 1945, but the idea was never implemented.

By late June 1945, Filipino guerrillas from the U. S. Army Forces in the Philippines (Northern Luzon) USAFFE-NL led by Colonel R. W. Volckmann Company B with Blackburn's guerrillas liberated the Aparri area including Aparri Airfield.

On June 23, 1945 C-47s drop paratroopers from the 11th Airborne Division (11th Airborne), 511th Parachute Infantry Regiment (511th PIR) near Aparri at Calamaniugan near the mouth of the Cagayan River without incident. Soon afterwards, C-46 Commandos towing seven CG-4 gliders manned by the 188th Glider Infantry Regiment (188th GIR) also land without incident. This attack was the first and only time gliders were used in combat in the Pacific Theater. On the ground, the paratroopers linked up with a large force of Filipino guerrillas. Their combined force advanced southward until making contact with the U. S. Army 37th Division.
