Landing at Arawe

Landing at Arawe. The Landing at Arawe was a battle during the Pacific War and a component of the larger Operation Cartwheel, the Allied strategy to isolate the major Japanese base at Rabaul. Conducted by United States forces on 15 December 1943, the operation aimed to secure a harbor and establish a patrol torpedo boat base on the southwestern coast of New Britain. While achieving its objectives, the landing's strategic necessity was later debated among historians.

Background

By late 1943, the Allied advance in the South West Pacific under General Douglas MacArthur was progressing through the Solomon Islands campaign and along the coast of New Guinea. The overarching goal of Operation Cartwheel was the neutralization of the formidable Japanese stronghold at Rabaul. To support future operations, such as the impending Battle of Cape Gloucester, Allied planners sought secondary landing sites on New Britain to divert Japanese attention and secure forward bases. The Arawe peninsula, with its potential for a protected anchorage, was identified as a suitable location for launching reconnaissance and torpedo boat operations against Japanese barge traffic along the island's southern coast.

Planning and preparation

Planning for the Arawe operation, designated as Operation DIRECTOR, was conducted under the Alamo Force commanded by Lieutenant General Walter Krueger. The primary assault force was the 112th Cavalry Regiment, a dismounted unit led by Brigadier General Julian W. Cunningham. Extensive aerial reconnaissance was performed by the Royal Australian Air Force and United States Army Air Forces units. A key element of the deception plan involved a feint landing near Cape Merkus to draw Japanese defenses away from the main beaches. Naval support and transport were provided by elements of the United States Seventh Fleet, including destroyers and landing craft of the 2nd Engineer Special Brigade.

Opposing forces

The main Allied force consisted of the 112th Cavalry Regiment, reinforced by artillery batteries from the 148th Field Artillery Regiment and support from the United States Marine Corps squadron VMF-216 flying F4U Corsair aircraft. Naval gunfire support came from the destroyers USS ''Conyngham'', USS ''Shaw'', and USS ''Drayton''. The Japanese garrison on the Arawe peninsula was relatively small, comprising elements of the 51st Division and naval personnel under the overall command of General Yasushi Sakai at Rabaul. Local defenses were commanded by Major Iwao Matsuda and included a company of the 1st Battalion, 81st Infantry Regiment, totaling roughly 120 soldiers, with reinforcements available from the 17th Division at Cape Merkus.

Landing and initial operations

The landing commenced before dawn on 15 December 1943, following a naval bombardment. The main assault went ashore at Pilelo Island and on beaches near the village of Umtingalu, while a diversionary force landed at House Fireman Beach. Initial resistance was light, but Japanese forces quickly organized counterattacks, including a notable but unsuccessful banzai charge on the first night. The Allies consolidated a perimeter on the peninsula, establishing their base. The most significant subsequent action was the Battle of Arawe, a series of clashes as Japanese reinforcements were brought in by barge from Cape Merkus, leading to intense fighting around the perimeter throughout December and January, often under air raids from Rabaul.

Aftermath

The Arawe beachhead was fully secured by 24 February 1944, having served its purpose as a secondary effort. The established PT boat base was used to interdict Japanese coastal supply routes, supporting the main Allied offensive at Cape Gloucester. Casualties for the United States Army amounted to 118 killed and 352 wounded, while Japanese losses were approximately 304 killed. The operation succeeded in fixing Japanese forces in southwestern New Britain, though some military analysts, such as Samuel Eliot Morison, later questioned its overall strategic value given the resources committed. The campaign contributed to the eventual isolation of Rabaul and the Allied advance toward the Philippines.
