2/10th Battalion (Australia)

The 2/10th Battalion ("The Adelaide Rifles") was an infantry battalion of the Australian Army that was raised for overseas service as part of the all-volunteer Second Australian Imperial Force (2nd AIF) during World War II. Formed in October 1939, it was the first 2nd AIF unit raised from the state of South Australia during the war; after completing a period of training in Australia, the battalion embarked for overseas service. Initially, it had been intended that the 2/10th and its parent brigade – the 18th Brigade – would be sent to the Middle East to join the other brigades of the 6th Division, but instead the 18th Brigade was sent to strengthen the garrison in the United Kingdom after France capitulated in mid-1940. Re-assigned to the 9th Division, the 2/10th remained in the United Kingdom undertaking defensive duties until late 1940 when it finally arrived in the Middle East, where the 18th Brigade became part of the 7th Division.

The battalion's first experience of combat came during an attack against the Italian garrison at Giarabub in March 1941. This was followed by defensive actions during the Siege of Tobruk later in the year before the 2/10th joined the Allied garrison in Syria, which had previously been captured from the Vichy French. In early 1942, following Japan's entry into the war, the 2/10th was withdrawn to Australia and in August 1942, at the height of the Japanese advance in the Pacific, the battalion was committed to the fighting around Milne Bay in the Territory of Papua, suffering heavy casualties in their debut in the Pacific. Further fighting came during the Battle of Buna–Gona in northern Papua before the 2/10th was brought back to Australia for re-organisation in March 1943. In August 1943, it was sent to the Territory of New Guinea, first undertaking jungle training near Port Moresby and then, in December 1943, moving inland into the Finisterre Mountains where they later fought the Battle of Shaggy Ridge. After being withdrawn to Australia in mid-1944, the battalion did not take part in further fighting until the final months of the war when they were committed to the fighting on Balikpapan in July 1945. Following the conclusion of hostilities, the 2/10th Battalion was disbanded in December 1945.

Formation and training in Australia
The 2/10th Battalion was established at the Wayville Showgrounds, in Adelaide, on 13 October 1939, as part of the all-volunteer Second Australian Imperial Force (2nd AIF), which was raised in Australia shortly after the outbreak of the war for overseas service. Organised into four rifle companies, designated 'A' through to 'D', and a headquarters company, the 2/10th was the first 2nd AIF unit raised from the state of South Australia during the war, and was colloquially known as "The Adelaide Rifles". The colours chosen for the battalion's unit colour patch (UCP) were the same as those of the 10th Battalion, a unit which had served during World War I before being raised as a Militia formation in 1921. These colours were purple over light blue, in a horizontal rectangular shape, although a border of gray was added to the UCP to distinguish the battalion from its Militia counterpart and the original World War I battalion.

Along with the 2/9th, 2/11th and 2/12th Battalions, the 2/10th was subordinate to the 18th Brigade, which was recruited from the less populous states of Queensland, Western Australia, South Australia and Tasmania, and was initially allocated to the 6th Division, the first of the 2nd AIF's four infantry divisions. The battalion's first commanding officer was Lieutenant-Colonel Arthur Verrier, a World War I veteran who had previously commanded the 43rd Battalion. He assumed command on 13 October 1939. After the battalion's recruits had concentrated at Wayville, the 2/10th moved to Woodside Camp, in the Adelaide Hills to city's east in early November, where they carried out initial training. In mid-December, they moved by train to New South Wales on the east coast of Australia where the battalion joined the other units of the 18th Brigade, and further training was completed at Greta Camp and then Ingleburn. In early May 1940, the battalion was ready to deploy overseas, and embarked on the transport ship RMS Mauretania (1938), which departed Sydney on 5 May 1940, bound for the Middle East.

Garrison duties in the United Kingdom
On 10 May 1940, after the 2/10th had departed Australia, the Germans launched a lightning assault across France and the Low Countries, which rapidly led to the capitulation of France and the evacuation of the British Expeditionary Force. As a result of Italy's entry into the war, coupled with concerns about a possible invasion of the United Kingdom, the Australian government decided to divert some of its troops from the Middle East. As a consequence, as the 18th Brigade was sailing towards the Middle East it was redirected to the United Kingdom. On 18 June 1940, the Mauretania docked at the port of Gourock, in Scotland. The brigade was subsequently re-allocated to the 9th Division and the Australians were transported to the south of England, eventually establishing themselves around Lopcombe Corner, on Salisbury Plain in Wiltshire. While there, a number of the battalion's personnel married local girls.

Amidst the backdrop of the Battle of Britain, while stationed on Salisbury Plain the battalion carried out garrison duties and undertook training to enable them to rapidly respond in the event that an invasion took place. They received a large amount of new equipment during this time to improve their mobility, including new Universal carriers, weapons and lightweight personal load-carrying equipment. They also experienced German air attacks for the first time, and on 8 July 1940, the battalion incurred its first casualty when one of its members was wounded in an air raid. In early October, the 2/10th undertook a large-scale exercise near Tidworth, and then in the middle of the month as winter set in, they were moved to Essex, where they replaced the tents they had been living in with the stone buildings and Nissen huts of Hyderabad Barracks, in Colchester. The battalion's stay there was short-lived, though, for the following month, after the threat of invasion had passed, the order arrived for the Australians to embark for the Middle East. The 2/10th subsequently entrained at Colchester in mid-November and moved north to Scotland where, on 17 November, they boarded the RMS Strathaird.



Fighting in the Middle East
Sailing via South Africa, shore leave was taken in Durban, which was reached on 12 December. The convoy remained there until late December when it continued on to Egypt via the Red Sea due to the threat of attack that was present in the Mediterranean; the battalion reached Port Tewfik just before the new year. The 18th Brigade was again re-assigned in February 1941, this time to the 7th Division, with whom they would see out the remainder of the war; at the same time, the brigade was converted from a four-battalion structure to three, and the 2/11th was transferred to help form the 19th Brigade. On 21 March 1941, the battalion undertook its first action of the war, when one of its companies – 'D' Company – supported the 2/9th Battalion in their attack on the Italian held fort at Giarabub. Meanwhile, the remainder of the battalion began preparations for deployment to Greece where an invasion was expected. These plans were interrupted when the 7th Division was committed to the fighting in North Africa in response to German gains in Cyrenaica. At this time, the 18th Brigade was sent to garrison the vital port of Tobruk as the 9th Division withdrew from Cyrenaica.

It was at Tobruk that the battalion fought its first major action as a complete unit in April 1941, when it undertook defensive actions during the Siege of Tobruk. During the Battle of the Salient, fought in early May, the 2/10th took over a position on the northern flank of the perimeter, relieving the 2/48th Battalion, coming under heavy air attack during the handover. After the initial German and Italian assault, on the evening of 3/4 May the 18th Brigade counter-attacked to retake positions lost; the 2/10th was given a supporting role, tasked with carrying out raids deep into the opposing forces' territory while the 2/9th and 2/12th Battalions attacked the northern and south-eastern flanks of the salient. In the fighting that followed, the 2/10th's casualties were six missing and fifteen wounded, but they inflicted heavy casualties upon their enemy before withdrawing back to the "Blue Line", about 2 mi behind the main defensive line where the counter-attacking reserve forces were positioned to respond to a deep penetration.

After the fighting in early May, the 2/10th was withdrawn to Pilastrino for a brief respite and placed in reserve, but by the middle of May, they had returned to the salient, and on 16 May advanced the line over 1000 yd. The 2/10th carried out further raids in "no man's land" as the siege continued, but in August the battalion was withdrawn to Palestine for training. In September 1941, the 2/10th were sent to Syria where they were assigned to the Allied garrison that had occupied the country following the conclusion of the Syria–Lebanon campaign and the defeat of the Vichy French forces there. The garrison was deployed in order to defend against a possible German attack from the Caucasus towards the strategically important Middle Eastern oilfields. During this time, the 2/10th Battalion was stationed near Aleppo, where the battalion manned outposts near the Syrian–Turkish border across a frontage that was several hundred miles long.

New Guinea campaigns
The 2/10th remained in Syria until January 1942 when, after having endured a freezing cold winter that included snow, it was transported back to Palestine in preparation for a return to Australia. Following Japan's entry into the war the previous December, and in light of Allied reverses in the Pacific, the Australian government had requested the return of some of its forces in order to bolster the defence of Australia due to concerns about a possible invasion. The 2/10th subsequently embarked on the Dutch passenger ship SS Nieuw Amsterdam (1937), bound for Australia in early February 1942. Stopping over in Bombay, the battalion was transferred to the transport Nevassa on which they continued the journey to Adelaide where they arrived in late March. A period of re-organisation and training followed around Kilcoy in Queensland. Following Japanese landings on the north coast of New Guinea in July, Australian forces in the area became involved in a series desperate defensive actions, as they were pushed inexorably back towards Port Moresby. By early August 1942, the situation for the Australians was critical, and at this time the battalion was committed to the New Guinea campaign.



On 5 August, the 2/10th embarked on the Dutch transport Both, departing from Brisbane. A week later, on 12 August, the 2/10th, along with the other two infantry battalions of the 18th Brigade, landed at Milne Bay, in the Territory of Papua where they reinforced the Militia units from the 7th Brigade who were defending the area. A fortnight later the Japanese landed a force at Milne Bay in an attempt to secure the airfields that the Australians had built there. In the ensuing Battle of Milne Bay, the Australians eventually won a significant victory. After the initial landing was held by the 61st Battalion, the 2/10th relieved them before taking part in heavy fighting around a mission station known as the KB Mission. The 2/10th suffered heavily, losing 43 killed and 26 wounded, and after passing through the lines held by the 25th Brigade, was placed in reserve around No. 3 Strip. One of the battalion's companies – 'C' Company – was detached to Normanby Island in September, where they captured several Japanese soldiers who had become isolated there.

In October, the 2/10th was flown to Wanigela, near the north Papuan coast, where they were tasked with carrying out patrols and defending the beach against a possible Japanese landing, and helping to construct an airfield. The battalion's next major action came in late December 1942 during the Battle of Buna–Gona, after being transported by sea to the beachhead front, landing just south of Cape Endaiadere. Heavily engaged around the disused Buna airstrip where the Japanese had constructed several bunkers, in a fortnight of fighting the battalion suffered over 300 casualties, including 112 killed. Another attack was made around Sanananda in mid-January 1943, before the 2/10th was withdrawn from the fighting, flying to Port Moresby in February. On 10 March, the battalion embarked upon the transport Willis Van Devander to return to Australia, landing in Cairns on 12 March.

After establishing itself around Ravenshoe, Queensland, the next three months was a period of flux for the battalion, with many men taking leave or being discharged due to tropical diseases or injuries from the previous campaign. The battalion was brought up to strength with a large draft of volunteers from the 11th Motor Regiment, a motorised Militia light horse unit consisting largely of Queenslanders and New South Welshmen. A period of rest and re-organisation followed during which the units of the 2nd AIF were converted to the Jungle Division establishment. After this, large-scale divisional manoeuvres took place in mid-July, after which the battalion received orders to sail for overseas again. Embarking upon the transport Canberra from Townsville, they arrived in Port Moresby in early August. After a period in which the 18th Brigade was held back in reserve at Port Moresby to defend the approaches to Lae, in December 1943 the 2/10th was sent into the Finisterre Mountains, where they joined the rest of the 7th Division whose campaign through the Markham and Ramu Valleys had culminated in heavy fighting around Shaggy Ridge during the first months of 1944. During this period, several British Army officers were attached to the battalion as observers, arriving from Burma.

The Battle of Shaggy Ridge proved to be the most significant action for the 2/10th during the fighting in Ramu Valley. The battalion commenced its advance from Cam's Saddle on 20 January, with one company forward, and another in support. Amidst heavy rain that turned the ground to thick mud and flooded the Faria River, over the course of several days, they undertook several attacks around the ridges, and patrols along the river to link up with the neighbouring 2/12th Battalion. The battalion then pushed a company forward at a time against the last Japanese resistance around the 4,100 feature, which was strongly fortified with barbed wire and defended with machine guns. Heavy artillery, mortars and air support helped reduce the Japanese position, which was eventually secured by 1 February. The battalion's losses during this period amounted to 16 men killed in action, or died of wounds, and 27 wounded. After Shaggy Ridge was taken the battalion advanced to the Kankiryo Saddle, where the 18th Brigade was relieved by the 15th Brigade. The 2/10th was moved into reserve along with the rest of the 18th Brigade around the Mene River, and in early May 1944 it were flown to Lae and withdrawn to Australia, being transported home on the Duntroon.

Borneo and disbandment


After disembarking in Townsville on 8 May 1944, a period of leave followed, after which the battalion reconstituted in July 1944 and went into camp at Samsonvale, near Brisbane. In August, they took part in a march through Brisbane, before travelling north to Cairns in September, from where they moved to Kairi, near Tolga. A large number of reinforcements arrived at this time, as the battalion was severely undermanned due to transfers or discharges from injuries or illnesses, and a new commanding officer, Lieutenant Colonel Thomas Daly, was appointed. After this, the 2/10th began a long period of training. As a result of indecision about the employment of Australian troops in the latter part of the war, they spent over a year waiting for their final campaign. This came in the final months of the war when they were committed to the fighting on Borneo.

Staging out of Morotai Island, early on the morning of 1 July 1945 they came ashore at Klandasan as part of Operation Oboe Two, which was launched to recapture Balikpapan. After landing they fought to wrest control of the high ground to the west of the beachhead – dubbed "Parramatta Ridge" by the Australians. During the fighting for Parramatta Ridge, the battalion pressed home its attack despite having no reserves left, and lacking direct fire support after the supporting tanks became bogged. In the days the followed, the battalion's attention turned to fighting around the town of Balikpapan itself and its port. On 6 July, they were withdrawn from the fighting, and placed in brigade reserve; the fighting for Parramatta Ridge cost the 2/10th fifteen killed and 41 wounded; several of these were caused when supporting US aircraft accidentally attacked the battalion's lines around Hill 87.

Although the battalion undertook a series of local patrols after this, the fighting around Parramatta Ridge constituted the 2/10th's last major action of the war. After the hostilities ended in mid-August following Japan's surrender, the battalion's personnel were slowly repatriated back to Australia in drafts for demobilisation and discharge. Others chose to remain in the Army including a group of about 70 personnel were transferred to other units for subsequent service in the 34th Brigade, which had been formed to undertake occupation duties in Japan as part of the British Commonwealth Occupation Force. The battalion's last commanding officer, Daly, would remain in the service, eventually becoming Chief of the General Staff in 1966–1971. The battalion was finally disbanded on 29 December 1945 while still at Balikpapan; upon disbandment there were only 42 members of the battalion left for the 2/10th's final parade. During this ceremony, the battalion flag was entrusted to the Militia 10th Battalion, which had served briefly in a garrison role in Australia during the war and which was subsequently re-raised in South Australia after the war.

Throughout the course of the war, a total of 3,008 men served with the 2/10th Battalion of whom 315 were killed or died on active service, and 525 wounded. Members of the battalion received the following decorations: two Distinguished Service Orders, one Member of the Order of the British Empire, seven Military Crosses, six Distinguished Conduct Medals, 14 Military Medals and 51 Mentions in Despatches.
