The Western New Guinea campaign was a series of actions in the New Guinea campaign of World War II. Dutch East Indies KNIL, United States and Australian forces assaulted Japanese bases and positions in the northwest coastal areas of Netherlands New Guinea and adjoining parts of the Australian Territory of New Guinea. The campaign began with Operations Reckless and Persecution, which were amphibious landings by the U.S. I Corps at Hollandia and Aitape on 22 April 1944. Fighting in western New Guinea continued until the end of the war.

New Guinea campaign part of the Pacific Theater of World War II

The New Guinea campaign of the Pacific War lasted from January 1942 until the end of the war in August 1945. During the initial phase in early 1942, the Empire of Japan invaded the Australian-administered territories of the New Guinea Mandate and Papua and overran western New Guinea, which was a part of the Netherlands East Indies. During the second phase, lasting from late 1942 until the Japanese surrender, the Allies—consisting primarily of Australian and US forces—cleared the Japanese first from Papua, then the Mandate and finally from the Dutch colony.

World War II 1939–1945 global war

World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

Major battles and sub-campaigns

Operations Reckless and Persecution Allied amphibious landings at Hollandia and Aitape

Operations Reckless and Persecution were the Allied amphibious landings at Hollandia and Aitape, respectively, which commenced the Western New Guinea campaign. Both operations commenced on 22 April 1944.

Landing at Aitape battle of the Western New Guinea campaign of World War II

The Landing at Aitape was a battle of the Western New Guinea campaign of World War II. American and Allied forces undertook an amphibious landing on 22 April 1944 at Aitape on northern coast of Papua New Guinea. The amphibious landing was undertaken simultaneously with the amphibious landings of Battle of Hollandia at Hollandia to isolate the Japanese 18th Army at Wewak.

Battle of Hollandia 1944 battle between American and Japanese forces during World War II

The Battle of Hollandia was an engagement between American and Japanese forces during World War II. It took place in spring of 1944 and was part of the New Guinea campaign. The time it took place was a very tumultuous time so it was very difficult for the Allies to invade. They needed to recover from great losses in previous battles. As a result, the Allies were not able to send in as many troops as they would have liked. The landings were undertaken simultaneously with the amphibious landings at Aitape to the east. The battle was an unqualified success for the US forces, resulting in a withdrawal by the Japanese to a new strategic defence line in the west of New Guinea and the abandonment of all positions in the east of the island.

Markham and Ramu Valley – Finisterre Range campaign

The Markham and Ramu Valley – Finisterre Range campaign, was a series of actions in the New Guinea campaign of World War II. The campaign began with an Allied offensive in the Ramu Valley, from 19 September 1943, and concluded when Allied troops entered Madang on 24 April 1944. During the campaign, Australian forces – supported by Australian and US aircraft – advanced through the Markham and Ramu Valleys during which there were minor clashes with Japanese forces, which withdrew towards their main defensive line in the Finisterre Range. The central geographical and strategic feature of the campaign was the imposing Shaggy Ridge, running north-south in the Finisterres; this was the scene of a climactic battle during which the Australians assaulted the Japanese positions in December 1943 and January 1944. Following the fighting around Shaggy Ridge, the Japanese withdrew towards the northern coast of New Guinea, where they were pursued by Australian and US forces advancing through the Finisterres and along the coast from Saidor. Following the capture of Madang, the Japanese eventually withdrew to Wewak where further fighting took place in 1944 and 1945.

The Aitape–Wewak campaign was one of the final campaigns of the Pacific Theatre of World War II. Between November 1944 and the end of the war in August 1945, the Australian 6th Division, with air and naval support, fought the Imperial Japanese 18th Army in northern New Guinea. Considered a "mopping up" operation by the Australians, and although ultimately successful for them with the Japanese forces cleared from the coastal areas and driven inland, amidst difficult jungle conditions, casualties from combat and disease were high. With Japan on the verge of defeat, such casualties later led to the strategic necessity of the campaign being called into question.
