- 109 - Pacific War - Drive on Sio , December 19-26, 1943

Last time we spoke about landings against Arawe, the continuation of the Bougainville campaign and some new action in the CBI theater. Despite a rubber boat disaster, the operation against Arawe went off successfully seeing another allied landing taking the Japanese by surprise. Now the Japanese would be forced yet again to launch a counter attack hoping to dislodge the allied forces from a new beachhead. Over on Bougainville the Marines performed some assaults against hills such as Hellzapoppin ridge to expand the perimeter enough so the Army boys would have an easier time of taking over. Over in the CBI theater, the onion man Wingate was given the task of expanding his chindits and the Americans wanted their very own chindit force. Stilwell decided the time was ripe to unleash a minor offensive in Burma and soon saw what looked like a weakened Japanese perimeter was in fact very strong.

Troop A was supposed to land an hour before the main landing to cut the coastal road near Umtingalu village and Troop B would land at Pilelo island to cover the main passage to the harbor. Troop A was a disaster. Their 15 rubber boats were met with 25 mm dual purpose guns that sank 12 boats, killed 12 men and wounded another 70. Troop B was more successful landing on Pilelo and capturing the radio station before engaging in a fire fight. For the main landing at House FIreman Beach, there was little resistance. Sporadic machine gun fire was silenced by rockets as the men landed. The Japanese tossed some air strikes to hit further landings and convoys, but allied CAP managed to limit the damage.  A few days after the landing, the Komori Detachment reached the village of Didmop along the Pulie River where they paused to reorganize and rally the incoming survivors fleeing the landing area. The difficult terrain and river crossings prevented Komori and his men from assembling into offensive positions until December 25th. Meanwhile back on the 18th, the 1st battalion, 141st regiment began an advance from the Itni region aboard 7 barges. Unfortunately for them, two LCVP’s bearing 19 men on patrol had been sent by Cunningham to Cape Peiho. The two forces ran into another and after an exchange of gunfire the US soldiers abandoned their LCVP’s and retreated back along the Arawe coast. Another patrol traveling by LCVP was also fired upon by Japanese barges near Umtingalu that same day, but was able to return to Cape Merkus. On Christmas night, 100 men of the Komori detachment assaulted the main line of defense across the neck of the peninsula. The inexperienced American cavalrymen of the 112th managed to repel, albeit with some difficulty. The attack prompted General Cunningham to believe Komori was in charge of the lead element of a much larger force, most likely enroute from Gasmata. He therefore requested reinforcements and General Krueger responded by dispatching a company of the 158th infantry by PT Boats. Meanwhile the lack of results from the attack prompted Komori to defer further attacks until the arrival of Major Tobuse’s
