The Battle of the Coral Sea
A carrier battle at sea, connected directly to the Louisiades and the approaches to Papua.
What was at stake.
Japan’s Operation MO sought to take Port Moresby and Tulagi. Allied naval forces intervened in the Coral Sea. Aircraft carried out the principal attacks between the opposing carrier forces; the battle prevented the planned seaborne capture of Port Moresby. In 1942, Port Moresby was in the Territory of Papua.
The connection to Milne Bay’s islands.
The operation included a Japanese seaplane-base group for Deboyne in the Louisiade Archipelago. On 7 May, Rear Admiral John Crace’s cruiser group, including HMAS Australia and HMAS Hobart, moved to block the Jomard Passage approaches. These island passages connect the wider naval battle to the region now known as Milne Bay Province.
7–8 May: aircraft and carriers.
On 7 May, American carrier aircraft sank the Japanese light carrier Shōhō. On 8 May, USS Lexington was damaged, later abandoned and scuttled; USS Yorktown and the Japanese carrier Shōkaku were damaged. Zuikaku avoided physical damage but suffered losses in aircraft and aircrew. The ships’ losses and the outcome of the operation are different measures of the battle.
Why the outcome mattered.
The Royal Australian Navy describes a Japanese tactical victory alongside an Allied strategic victory: Allied ship losses were greater, but the Port Moresby seaborne invasion was stopped. Coral Sea and the later Battle of Milne Bay were separate operations, months apart.
The Battle of Milne Bay
A land and air battle for an Allied base on the bay’s northern shore.
How the base took shape.
The PNG Remembrance Trail describes Papuan labour in clearing land, the construction of the airfields and the arrival of RAAF Kittyhawks. Its scene-by-scene account is useful for understanding how terrain, rain, engineering and aircraft shaped the campaign.
The airfields were the objective.
Late on 25 August, Japanese troops landed to capture the Allied airfields. Major General Cyril Clowes commanded a garrison of nearly 9,000 Allied personnel, including Australian infantry and American engineering and anti-aircraft units. RAAF Nos 75 and 76 Squadrons flew P-40 Kittyhawks from nearby airstrips.
Defence, counterattack and withdrawal.
After advancing towards the airfields, Japanese forces attacked No. 3 Strip early on 31 August. The defenders held. Australian counterattacks followed along the north shore, with air support. Japanese forces withdrew and evacuated in early September. The Australian War Memorial dates the battle from 25 August to 7 September 1942.
The sea remained dangerous.
The transport Anshun was shelled and sunk while unloading at Gili Gili during the night of 6–7 September 1942. The Remembrance Trail describes the loss as part of the Japanese withdrawal. Shipping and supply crews faced their own dangers within the bay.
A major victory, described precisely.
Milne Bay was one of the first major Allied victories over Japanese land forces in the Pacific. Its significance should not be turned into the claim that Japan had never previously lost any land engagement. The victory also left the Allies in possession of an important base.
Papuan people are central to the history.
Communities experienced invasion, killings and disruption, as well as contributing labour, nursing and rescue. DVA records killings of Papuan civilians during the fighting. PNG Tourism notes that wartime deaths among local people were incompletely recorded; a military casualty total is not a complete measure of the human cost.
Maiogaru (Gimuleia) Taulebona.
The AWM records this mission-trained nurse treating wounded RAAF airman John Francis Fitzgerald Donegan after local people rescued him following the sinking of a crash boat on 28 August 1942. She received the Loyal Service Medal in 1943. Her name appears in different spellings in published accounts; this profile follows the linked AWM record.
The wider region at war
Fighting, evacuations, unopposed landings and the work of sustaining a major Allied base.
Samarai: destruction before the Milne Bay battle.
An AWM photograph records Australian personnel setting Samarai alight in March 1942 under orders from Port Moresby. This evacuation and destruction belongs in the wartime story, but was not the August Battle of Milne Bay. September photographs show the aftermath and should not be mistaken for the date of the original destruction.
Goodenough Island: fighting in late October 1942.
The 2/12th Australian Infantry Battalion fought Japanese troops on Goodenough Island. The AWM’s battle-honour record gives 22–26 October 1942. This was another island operation within today’s Milne Bay region, distinct from the fighting at Milne Bay in August and September.
Kiriwina and Woodlark: Operation Chronicle.
US forces landed on Kiriwina and Woodlark on 30 June 1943. These were unopposed landings, not battles against a defending Japanese garrison. The islands became sites for Allied air operations. The archive film in the film library shows troops embarking at Milne Bay and landing in the Trobriands during June–July 1943.
The base after the battle.
Milne Bay continued as a major Allied operational and supply base. Operation Lilliput carried troops and supplies onward to Oro Bay in support of the campaign in Papua. Airfields, fuel, shipping and labour connected the bay with later operations. A 1944 photograph of Papuan fuel workers shows this continuing role, well after the 1942 battle.
14 April 1943: another air attack.
The Remembrance Trail records a Japanese air raid on Milne Bay on 14 April 1943, met by RAAF Kittyhawks. Fighting in August–September 1942 did not mark the end of wartime danger. The base continued to support Allied operations, including staging for the September 1943 landing at Lae.
Before the Second World War
Documented local conflicts, labour-trade coercion and colonial violence.
Reading the earlier record.
These episodes are a documented selection, not a complete catalogue of the region’s conflicts. Many written accounts were made by colonial officials or outside observers. Community histories and oral accounts deserve attribution and care; gaps in the surviving record do not justify inventing a war, a date or a battle name.
Laughlan Islands, 1883.
Historian Hank Nelson records William McMurdo, the government agent aboard the labour-recruiting Stanley, responding to recruits’ desertion by burning houses and a trading station in the Laughlan Islands and destroying canoes. The episode connects regional violence with the Queensland labour trade. It was coercion and destruction, rather than a formally named war.
Misima, 1886.
Nelson describes a confrontation involving an HMS Swinger shore party on Misima, followed by HMS Diamond shelling the shore, burning a village and destroying canoes. His account places the incident in a context of hostility towards labour recruiters. It records colonial naval reprisals, rather than a single shared story for every island community.
Gulewa and Hariba: intervention in 1892.
A Gulewa raid on Hariba preceded William MacGregor’s January 1892 visit to Misima. Nelson describes subsequent armed government and police intervention, alongside Gulewa claims that earlier Hariba attacks had gone unpunished. Local retaliation and colonial authority intersected. The available account does not establish an exact date for the preceding raid.
The moving and still record.
Films remain on this page when expanded. Each record identifies the date, maker or holding institution and what the material shows. Some archive films are silent; contemporary interviews contain the claims and perspectives of their time.
Photographs with their dates intact.
A later base photograph is evidence of that later moment. Select a photograph to see its complete frame, then follow its archive record for the catalogue description.

Begin with local remembrance.
PNG Tourism recommends Alotau’s Massim Museum, the Turnbull Memorial and the Battle of Milne Bay Memorial. The museum’s local nursing-heroine exhibit is a way into histories that military operations alone cannot explain.
Arrange access and guiding locally, ask before photographing people or entering community land, and leave relics where they belong. Historic locations are also people’s homes and places of remembrance.
Find a local tour connectionUse the archive as evidence.
- Compare the dates and aims of Coral Sea and Milne Bay. What connects them, and what separates them?
- Choose a photograph. Who made it, when was it made, and what lies outside the frame?
- Watch a period film and the modern naval explainer. How do their purposes and viewpoints differ?
- Trace the contribution of Papuan workers, communities and nurses. Whose experiences are still missing from the records?
- Explain why an unopposed landing, a colonial reprisal and a battle should be described differently.
How this resource handles evidence.
Dates and events link to museum, naval, government and scholarly records. Where authoritative accounts differ, this resource avoids unsupported precision. It uses the AWM’s battle-date ranges, distinguishes later footage from battle footage, and follows the linked record when spelling a person’s name. Earlier conflicts are a documented selection; this is not a complete record of every community’s oral or written history.
“Milne Bay region” refers to places within today’s province and their wartime sea approaches. Other PNG campaigns may provide context, but Kokoda, Buna–Gona and Rabaul are not presented here as local Milne Bay battle sites.
