The25th Brigade was abrigade-sizedinfantry unit of theAustralian Army that served during theSecond World War. Raised in July 1940 and consisting of three infantrybattalions, the 25th Brigade initially served in theUnited Kingdom, where it formed part of the garrison tasked with defending against a possible German invasion. In 1941, the brigade was redeployed to theMiddle East where it took part in theSyria–Lebanon campaign fighting several actions aroundMerdjayoun andJezzine.
Following Japan's entry into the war, the 25th Brigade was transferred back to Australia and subsequently took part in the fighting inNew Guinea. Throughout 1942–1943, the brigade fought in the final stages of theKokoda Track campaign and aroundBuna–Gona. Later, they took part in the fighting aroundLae andShaggy Ridge, before being withdrawn to Australia for a long period of rest and reorganisation. In 1945, the 25th Brigade was committed to theBorneo campaign, carrying out anamphibious landing at Balikpapan in July 1945 before being disbanded in 1946.
The 25th Brigade was raised in June 1940 fromSecond Australian Imperial Force (AIF) personnelin the United Kingdom. Upon formation, the brigade's headquarters was opened atTidworth, inWiltshire.[1] The brigade was created following theFall of France, initially as a temporary formation that would defend southern England, in the event of aninvasion by German forces.[2] It had an foundational establishment of 1,759 personnel; a majority were drawn from service support corps of the6th Division, although roughly a quarter of this number were diverted from infantry reinforcements bound initially for AIF units in the Middle East.[3] Upon formation, the brigade consisted of only three infantry battalions instead of the four that had been the usual Australian establishment up to that time,[2] due to manpower shortages and its component units were the 70th, 71st and 72nd Battalions, although these were later re-designated as the2/31st,2/32nd and2/33rd Battalions.[3] When formed, each of these battalions consisted of only threecompanies, instead of the usual four, although these companies were later added when the brigade deployed to the Middle East after January 1941.[1]
Originally, the 25th Brigade was part of the newly established9th Division, however, after being dispatched to the Middle East in 1941 it was transferred to the7th Division, with which it remained for the rest of the war.[3] Upon arrival, the brigade was sent to Palestine, although it moved toIkingi Maryut, in Egypt, in April 1941 as preparations were made to deploy toGreece, in support of the 6th Division. However, in response to German moves in North Africa, the brigade was deployed toMersa Matruh in the Western Desert, remaining there until relieved in May.[1] By this time, the brigade's establishment was completed, and it consisted of 3,500 men[4] and was composed of the2/25th, 2/31st and 2/33rd Battalions, with the 2/32nd having been transferred to the24th Brigade and the 2/25th being re-assigned to the 25th in its stead as part of a re-organisation of the 2nd AIF as the more combat ready units were shifted to the 7th Division in preparation for operations, while those still forming were transferred to the 9th Division.[5]
After this the brigade took part in theSyria–Lebanon campaign in June–July 1941, fighting against theVichy French.[6] During this campaign, the brigade was allocated to the centre of the Allied advance, with the21st Brigade advancing on its flank along the coast. The campaign was short, but hard fought and the brigade's major actions during this time included an attack onMerdjayoun and fighting aroundJezzine.[7][8][9] After thearmistice was signed in July, the 25th Brigade moved toBeirut where they undertook garrison duties. A further move took place in September, when the brigade was transferred toTripoli to construct defensive positions. They remained there until January 1942, when the 25th Brigade was withdrawn to Julius, in Palestine.[10]
In early 1942, followingJapan's entry into the war and concerns about the strategic situation in the Pacific, the 25th Brigade—along with the rest of the 7th Division—were brought back to Australia to help reinforce theMilitia units that were trying to hold back the Japanese advance in New Guinea.[7] Arriving inAdelaide, in South Australia, the 25th Brigade's personnel were granted a brief period of leave before the brigade reconstituted aroundCasino, New South Wales, where they took over the defences from the15th Motor Regiment amidst concerns of a Japanese invasion. In May, the brigade moved toCaboolture, Queensland, and assumed a defensive role around the beaches of theSunshine Coast. As the fighting between Japanese and Australian forces along theKokoda Track intensified, the brigade received orders to deploy toNew Guinea, and they subsequently arrived inPort Moresby in September 1942.[11]
As the situation was dire for the Australians, upon arrival at Port Moresby, the 25th Brigade was committed to theKokoda Track campaign, and was sent up the track toIoribaiwa, where they reinforced the heavily depleted21st Brigade. After heavy fighting, a withdrawal was undertaken to Imita Ridge, and by the end of the month the Japanese advance towards Port Moresby had reached its limit. After this, the Japanese began to withdraw north, and the Australians began a tentative pursuit. This saw the 25th Brigade involved in heavy fighting aroundEora Creek and Templeton's Crossing in October, which was followed by the recapture of Kokoda on 2 November. Following the occupation of Kokoda, the 25th Brigade began the advance towards Wairopi. The Japanese had established strong defences aroundOivi and Gorari, and while the 21st Brigade carried out a frontal assault, the 25th Brigade advanced further to the south and then attacked the Japanese rear. The Japanese then withdrew across theKumusi River, after which the 25th Brigade continued towards the coasts, joining the fighting aroundGona. At Gona they came up against a well entrenched force, and suffered heavy casualties. As a result, the brigade was withdrawn to Donadabu in December 1942 and then flown back to Australia the following month.[11]
A six month period of home service in Australia followed, during which intensive training was carried out aroundRavenshoe, Queensland, on theAtherton Tableands.[12] In September 1943, the brigade was committed to thecapture of Lae,[11] as the 7th Division was flown intoNadzab to begin the advance from there, while the9th Division carried out another advance on Lae from the coast. While emplaning in Port Moresby, the 2/33rd Battalion suffered heavy losses when a Liberator bomber crashed on take off amongst trucks carrying members of the battalion. Nevertheless, the brigade arrived in Nadzab and on 9 September began their advance through theMarkham Valley and after clashes around Jensen's and Heath's Plantations, the brigade entered Lae on 16 September.[13] Following the capture of Lae, the brigade was flown toKaiapit and the took part in theadvance through the Finisterre Range, culminating in theBattle of Shaggy Ridge.[14][15] After being relieved in early 1944 by the15th Brigade, the 25th was withdrawn to Port Moresby in January 1944 and returned to Australia the following month.[16]
After this, the 25th Brigade did not see action for over a year. During this period, the brigade was located initially atStrathpine, Queensland, before moving toKairi as they undertook training in Queensland before taking part in the final western Allied amphibious operation of the war—thelanding at Balikpapan in July 1945.[17][18] This operation was part of the widerBorneo campaign. The strategic value of this campaign has since been questioned, however, ultimately the 25th Brigade's involvement in it was successful and it proved their last involvement in the war.[3][17] Staging out ofMorotai, the brigade landed at Balikpapan in July, following the18th and 21st Brigades ashore. Advancing up the Milford Highway, the brigade advanced towards Batuchampar, and by the end of the month the Australians began mopping up operations. The Japanese surrendered in August 1945, after which the brigade served as occupation troops in Dutch Borneo until civilian authorities could be re-established.[16] The brigade was disbanded shortly thereafter in 1946.[3]
