The Australian contribution to the Battle of Normandy involved more than 3,000 military personnel serving under British command. The majority of these personnel were members of the Royal Australian Air Force (RAAF), though smaller numbers of Australians serving with the Royal Navy and British Army also participated in the fighting prior to and after the Allied landings on 6 June 1944. While all the RAAF units based in the United Kingdom (UK) took part in the battle, Australians made up only a small portion of the Allied force.

The Australians who supported the D-Day invasion included between 2,000 and 2,500 RAAF airmen in Australian squadrons and British Royal Air Force units, and approximately 500 members of the Royal Australian Navy serving on Royal Navy vessels, as well as a small number of Australian Army officers and merchant seamen. The army personnel and thousands of Australian airmen also took part in the subsequent Battle of Normandy between June and August 1944, and an RAAF fighter squadron operated from airfields in Normandy. Throughout the campaign, Australian airmen provided direct support to the Allied ground forces by attacking German military units and their supply lines, as well as forming part of the force that defended the beachhead from air attack and manning transport aircraft. Australians also indirectly supported the campaign by attacking German submarines and ships that threatened the invasion force. The 13 Australian Army officers who took part in the campaign filled a variety of roles in British units in order to gain experience that they could take back to Australia.

Australian personnel also took part in the invasion of Southern France in August 1944, and RAAF airmen continued to operate against German forces until the end of the war in May 1945. However, the relatively low casualties suffered by the Allied air forces during the fighting in Normandy and subsequent campaigns resulted in an over-supply of trained Australian aircrew in the UK, hundreds of whom were never assigned to a combat role. Australia's contribution to the fighting in Normandy is commemorated in memorials and cemeteries in London and Normandy.

Background

In 1944 Australia's war effort was focused on the Pacific War, and most elements of the country's military were in Australia and the islands to its north.Stanley (2004) Nevertheless, substantial numbers of RAAF personnel, most of whom had been trained through the Empire Air Training Scheme (EATS), were stationed in the United Kingdom (UK) and took part in operations against Germany. The Australian Government had very little influence over where Australian graduates of EATS were posted, and many were assigned directly to British units.Dennis et al. (2008), pp. 197–198 As of 6 June 1944, 1,816 Australian airmen (including 584 pilots) were posted to RAF squadrons. Many of the thousands of Australian ground crew in the UK at this time were also serving with RAF units.Herington (1963), p. 17 In addition, ten RAAF flying squadrons were stationed in the UK. These included one regular RAAF unit, No. 10 Squadron, and nine temporary Article XV squadrons, which had been formed under the agreement that underpinned EATS. While the Article XV squadrons were nominally Australian, most included a substantial proportion of personnel from Britain and other Commonwealth countries; as of 1 June 1944 they were manned by 796 Australian aircrew and 572 airmen from other countries.Long (1973), p. 377 Owing to an over-supply of aircrew trained through the Empire Air Training Scheme, there were also hundreds of RAAF airmen in the UK who were assigned to personnel depots while they waited to be posted to a combat unit; prior to the invasion these unattached airmen were considered an asset by the Allied air forces as they could rapidly replace casualties.Herington (1963), pp. 282–283

The Australian air units were under the command of the RAF, which had 306 squadrons located in the UK at the time of the landings in Normandy.Herington (1963), p. 16 Two RAAF squadrons were assigned to the Second Tactical Air Force (2TAF), which was to provide direct support to the Allied armies during the campaign; No. 453 Squadron operated Spitfire fighters as part of No. 125 Wing and No. 464 Squadron flew Mosquito light bombers as part of No. 140 Wing.Stanley (1987), p. 149Shores (1970), pp. 281–282 Four Australian heavy bomber squadrons formed part of RAF Bomber Command; No. 460, No. 463 and No. 467 Squadrons were equipped with Lancasters and No. 466 Squadron flew Halifaxes. No. 456 Squadron, which was a specialist night fighter unit equipped with Mosquitos, formed part of Air Defence of Great Britain and was assigned to protect the invasion force.Stanley (1987), p. 149 Three other RAAF squadrons in the UK would also support operations in Normandy as part of Coastal Command; No. 10 and No. 461 Squadrons were equipped with Sunderland flying boats and flew patrols of the waters around the UK and France, while No. 455 Squadron operated against German surface shipping using Beaufighter strike aircraft.Air Power Development Centre (2004), p. 2

In addition to the RAAF airmen operating as part of the RAF in the UK, hundreds of Royal Australian Navy (RAN) personnel were serving with the Royal Navy (RN) at the time of the Battle of Normandy. No Australian warships took part in the operation, however. Most of the Australian officers serving with the RN were members of the Royal Australian Naval Volunteer Reserve (RANVR).Gill (1968), p. 445 Four RAN sub-lieutenants who had been sent to the UK to undergo training were also assigned to RN landing craft units to help address a shortage of officers capable of coordinating operations by these vessels.

Thirteen Australian Army officers were attached to the British Army units that fought in Normandy. These officers had been posted to the UK to gain experience in planning and conducting large-scale amphibious operations, which would improve the army's procedures ahead of Australian landings in the Pacific. A single officer represented each of the Army's corps, and the personnel sent to the UK included some of the most talented and experienced members of the service.Jackson (2004), p. 13

Pre-invasion preparations

Few Australians were involved in planning the invasion.Herington (1963), p. 13 Some of those who had planning responsibilities included Lieutenant Colonel Ronald McNicoll, who served on the Operations Staff of the Supreme Headquarters Allied Expeditionary Force;Jackson (2004), p. 14 Air Commodore Frank Bladin, Senior Air Staff Officer for No. 38 Group RAF;Herington (1963), p. 15 Lieutenant Commander Victor Smith, Flag Officer for British Assault Area's air planning officer;Birch (1979) and Major Douglas Vincent, a signals officer attached to the headquarters of the British XXX Corps. Australian-born Air Commodore Edgar McCloughry, who had served with the RAF since 1919, headed the Allied Expeditionary Air Force Bombing Committee, which prepared air plans for the invasion.

During April and May the Allied air forces struck at German airfields as well as aircraft factories and repair facilities in France. No. 463 and No. 467 Squadrons participated in raids on airfields and factories near Toulouse on the nights of 5/6 April and 1/2 May, and bombed an airfield near Lanvéoc on the night of 8/9 May. The first of these raids involved 148 aircraft and was led by No. 467 Squadron's commanding officer, Wing Commander John Balmer.Herington (1963), pp. 19–21 2TAF also conducted 12 raids on German airfields during this period, of which eight involved individual Australians posted to RAF light bomber squadrons.Herington (1963), p. 21 Australians serving in the fighter squadrons of No. 10 Group RAF also occasionally took part in "ranger" operations over northern France in search of German aircraft. In addition, the 31 Australian pilots posted to RAF photo reconnaissance units frequently conducted sorties to monitor German dispositions along the coast of the English Channel.Herington (1963), p. 25 On 29 May Squadron Leader Douglas Sampson, who was posted to No. 16 Squadron RAF, took detailed photographs of Utah Beach which enabled the American force which was to land there to locate most of the German positions in the area.

The Allies also conducted a major air offensive against the French railway network and bridges over the river Seine from April to June. Bomber Command made 53 raids against these targets, of which 25 involved the four Australian heavy bomber squadrons. A total of 17 Australian bombers were lost during these operations, including six that German fighters shot down during an attack on the marshalling yards at Lille on the night of 10/11 May.Herington (1963), pp. 26–30 In addition, Australians took part in 29 of the 46 raids conducted by 2TAF's light bombers against French railway infrastructure.Herington (1963), p. 31 Australian fighter pilots, including all of No. 453 Squadron on occasion, escorted some of these raids and conducted ground attack sorties targeting railway rolling stock.Herington (1963), pp. 31–32 2TAF's fighter-bombers also attacked bridges over the river Seine from April as part of an effort to seal off the Normandy region, and Australian pilots posted to British squadrons were involved in a small number of these operations. No. 453 Squadron attacked bridges and viaducts near Normandy on 27 April and 2 May.Herington (1963), pp. 32–33

Australians participated in attacks on German defences in France in the weeks before D-Day. No. 453 Squadron made four raids on radar stations in late May and early June, and RAAF pilots serving with British fighter and fighter-bomber squadrons took part in other such attacks.Herington (1963), pp. 33–34 The four Australian heavy bomber squadrons contributed aircraft to raids on radar stations and communications facilities in the week before the landing.Herington (1963), pp. 34–35 These units also struck German coastal batteries along the channel coast on nine occasions between 8 and 29 May; Australians serving with British light bomber units took part in a further 14 raids on German batteries.Herington (1963), pp. 35–36 The RAAF heavy bomber squadrons and Australians in RAF light and heavy bomber units also participated in raids against German Army camps in France and Belgium during May. The Australian squadrons suffered heavy losses in several of these attacks, including seven aircraft lost during a raid on the 21st Panzer Division's facilities at Mailly-le-Camp on the night of 3/4 May.Herington (1963), pp. 37–38 In addition to these attacks on German positions, Bomber Command struck the seven largest German munitions factories and ammunition dumps in France during late April and early May; the four Australian squadrons participated in five of these operations, and no Australian aircraft were lost.Herington (1963), pp. 38–39

Leading up to the invasion, the RAF intensified its operations against German submarines and ships operating near France. Coastal Command aircraft destroyed six submarines within eleven days during May; Australian aircrew contributed to three of these sinkings.Long (1973), p. 379 Bomber Command also expanded its program of laying naval mines from April, and No. 460 Squadron as well as Australians posted to RAF light and heavy bomber units took part in several minelaying operations in the Baltic Sea and Heligoland Bight.Herington (1963), pp. 44–45 Coastal Command's anti-shipping force, which included the RAAF's No. 455 Squadron, mainly undertook training exercises from April, but occasionally attacked German convoys in the English Channel.Herington (1963), pp. 43–44
