Battle of Fromelles The Battle of Fromelles ( ; 19 – 20 July 1916 ) , was a British military operation on the Western Front during World War I , subsidiary to the Battle of the Somme . General Headquarters ( GHQ ) of the British Expeditionary Force ( BEF ) had ordered the First Army and Second Army to prepare attacks to support the Fourth Army on the Somme to the south , to exploit any weakening of the German defences opposite . The attack took place from Lille between the Fauquissart – Trivelet road and Cordonnerie Farm , an area overlooked from Aubers Ridge to the south . The ground was low - lying and much of the defensive fortification on both sides consisted of breastworks , rather than trenches . The operation was conducted by XI Corps of the First Army with the 61st Division and the 5th Australian Division , Australian Imperial Force ( AIF ) against the 6th Bavarian Reserve Division , supported by two flanking divisions of the German 6th Army . Preparations for the attack were rushed , the troops involved lacked experience in trench warfare and the power of the German defence was significantly underestimated , the attackers being . The advance took place in daylight , against defences overlooked by Aubers Ridge , on a narrow front which left German artillery on either side free to fire into the flanks of the attack . A renewal of the attack by the 61st Division early on 20 July was cancelled , after it was realised that German counter - attacks had already forced a retirement by the Australian troops to the original front line . On 19 July , General von Falkenhayn , the German Chief of the General Staff , had judged the British attack to be a long - anticipated offensive against the 6th Army . On the next day when the effect of the attack was known and a captured operation order from XI Corps revealed the limited intent of the operation , Falkenhayn ordered the Guard Reserve Corps to be withdrawn to reinforce the Somme front . The Battle of Fromelles had inflicted some losses on the German defenders but gained no ground nor deflected many German troops bound for the Somme . The attack was the début of the AIF on the Western Front and the Australian War Memorial described the battle as " the worst 24 hours in Australia ' s entire history " . Of , were incurred by the 5th Australian Division ; German losses were prisoner . Background . The course of the Battle of the Somme ( 1 July – 18 November 1916 ) had led the British GHQ on 5 July to inform the commanders of the other three British armies , that the German defences from the Somme north to the Ancre river might soon fall . The First and Second army commanders were required to choose places to penetrate the German defences , if the attacks on the Somme continued to make progress . Any gaps made were then to be widened , to exploit the weakness and disorganisation of the German defence . The Second Army commander , General H . Plumer was occupied by preparations for an offensive at Messines Ridge but could spare one division for a joint attack with the First Army at the army boundary . On 8 July the First Army commander General C . Monro , ordered the IX Corps commander Lieutenant - General R . Haking to plan a two - division attack ; Haking proposed to capture Aubers Ridge , Aubers and Fromelles but next day Monro dropped Aubers Ridge from the attack , as he and Plumer had concluded that with the troops available , no great objective could be achieved . On 13 July , after receiving intelligence reports that the Germans had withdrawn approximately nine infantry battalions from the Lille area from , GHQ informed the two army commanders that a local attack was to be carried out at the army boundary around 18 July , to exploit the depletion of the German units in the vicinity . Haking was ordered to begin a preliminary bombardment , intended to appear to be part of a large offensive , while limiting an infantry attack to the German front line . On 16 July discussions about the attack resumed , as the need for diversions to coincide with operations on the Somme had diminished when the big victory of Bazentin Ridge ( 14 July 1916 ) had not led to a general German collapse . Sir Douglas Haig the Commander - in - Chief of the BEF , did not want the attack to take place unless the local commanders were confident of success and Monro and Haking opposed postponement or cancellation of the attack . The weather had been dull on 15 July and rain began next day , soon after Monro and Haking made the decision to proceed with the attack . Zero hour for the main bombardment was then postponed because of the weather and at Haking delayed the attack for at least ; after considering cancellation , Monro postponed the attack to 19 July . Prelude . British offensive preparations . The Second Army provided the 5th Australian Division , the artillery of the 4th Australian Division and heavy guns and trench mortars to XI Corps , to participate in an attack from the Fauquissart – Trivelet road to La Boutillerie with the 31st Division and 61st Division . A shortage of artillery and the lack of training and experience in the Australian divisional artilleries and some of the heavy batteries , led to the attack front being reduced to between the Fauquissart – Trivelet road and Delangre Farm . The ground to be attacked was waterlogged , flat and easily overlooked from Aubers Ridge , behind the German front line to the south . The 39th Division and 31st Division moved their boundaries north as the 61st Division concentrated along its attack front from the Fauquissart – Trivelet road to Bond Street . The 20th Division moved its boundary south to Cordonnerie Farm to take over the left of the 5th Australian Division , which concentrated the divisional frontage from Cordonnerie Farm to Bond Street . The twelve attacking battalions were supported by more artillery than at Aubers Ridge in May 1915 , when a similar number of battalions attacked in the same area . More ammunition was available than in 1915 and trench mortars were added to the artillery for wire - cutting . With support from First Army artillery to the south , guns and guns were ready , which gave a greater concentration of heavy artillery than that of the Fourth Army on the first day of the Somme . After several postponements for weather , on 18 July visibility increased and the artillery bombardment proceeded . The bombardment of the German front at La Bassée was repeated and provoked retaliation from the German artillery . Overnight British infantry patrols reported that no movement was visible in the German lines , which appeared to be weakly held . German covering parties stopped Australian raiders , on the right flank of the 5th Australian Division front , where the wire appeared to be intact except for gaps on the left . 19 July began hazy but the time of the artillery zero hour was fixed for , ready for the infantry attack to begin at A special heavy artillery bombardment began on the Sugarloaf at by which time a German counter - bombardment was falling on all of the attack front , causing casualties to the Australians and the field artillery crews of the 61st Division at Rue Tilleloy . Several ammunition dumps were exploded and the decoy lifts by the British artillery failed to deceive the Germans . The Australian and British infantry began to move into no man ' s land at British plan of attack . The German salient at Fromelles contained some higher ground facing north - west , known as the Sugarloaf . The small size and height of the salient gave the Germans observation of no man ' s land on either flank . The Australian 5th Division , under Major General J . W . McCay was to attack the left flank of the salient by advancing south as the 61st Division attacked the right flank from the west . Each division was to attack with its three brigades in line , with two battalions from each brigade in the attack and the other two in reserve , ready to take over captured ground or to advance further . Haking issued the attack orders on 14 July , when wire - cutting began along the XI Corps front . It was intended that the bombardment would inflict mass casualties on the German infantry , reducing them to a " state of collapse " . The British infantry were to assemble as close to the German lines as possible , no man ' s land being wide , before the British artillery fire was lifted from the front line ; then the infantry would rush the surviving Germans while they were disorganised , advancing to the German second line . Heavy artillery began registration and a slow bombardment on 16 July and two days of bombardment began either side of La Bassée canal as a diversion . The main bombardment was to begin at midnight on 17 / 18 July for seven hours ( rainy weather forced a postponement ) . Over the final three hours the artillery was to lift and the infantry show bayonets and dummy figures several times , to simulate an infantry advance and then the artillery was to resume bombardment of the front line , to catch the German infantry out of cover . German defensive preparations . Von Falkenhayn had ordered a construction programme on the Western Front in January 1915 , to make it capable of being defended indefinitely by a small force against superior numbers . A more elaborate and fortified front line was built with fields of barbed wire and carefully sited and camouflaged concrete machine - gun nests , with another trench close behind to shelter the trench garrison , during bombardments of the front line . To evade Allied long - range artillery - fire , intended to obstruct the movement of reinforcements from the new rear defences , communication trenches were built . The front line was to be held at all costs as the main line of resistance but in May 1915 Falkenhayn ordered a reserve line to be built along all of the Western Front , behind the front line , out of range of enemy field artillery , to contain any breakthrough and be occupied opposite a sector broken into , as jumping - off points by counter - attacking troops . If counter - attacks failed to recover the front line , the rear position could be connected to the uncaptured parts of the front line on either side . The construction programme was a huge undertaking , which took until autumn 1915 and had several opponents , notably the 6th Army commander Crown Prince Rupprecht , who claimed that a rear line would undermine the determination of soldiers to stand their ground . The front of the 6th Army had been quiet since the Battle of Loos ( 25 September – 14 October 1915 ) . In July 1916 the 6th Bavarian Reserve Division held a stretch of the front line with four regiments , from east of Aubers village , north to a point near Bois Grenier , each regiment having one battalion in the front line , one in support and one in reserve . On one regimental front there were with of concrete protection . After a British gas attack late on 15 July opposite Neuve Chapelle and Fauquissart , German artillery bombarded the British front line and a raid by of Bavarian Reserve Regiment 21 on the Australian lines , caused nearly and took three prisoners for a loss of . Battle . First Army . In the 61st Division area , infantry of the 182nd Brigade on the right flank , began to move into no man ' s land at through sally - ports , some of which were under fire from German machine - gunners and became " death - traps " . Two companies of the right - hand battalion , managed to get within of the German parapet with few losses and rushed the breastwork as the artillery lifted , finding the wire cut and the Germans incapable of resistance . Uncut wire held up the advance to the second line and German machine - gun fire from the right flank caused many casualties , as the survivors reached the objective . Reinforcements reached the front trench but the German flanking fire caused many casualties and German artillery began to bombard the captured area . The left - hand battalion lost more casualties in no man ' s land , then found the wire at the Wick salient uncut . German machine - guns caused many casualties and the few infantry who got through the wire , were shot down in front of the front trench , as reinforcements were also caught in no man ' s land and pinned down . In the centre , the 183rd Brigade was bombarded before the advance and shrapnel - fire stopped the infantry using the sally - ports . After climbing the British parapet both battalions were shot down in no man ' s land , a few men getting close to the German wire before being killed or wounded . On the left , the attacking battalions of the 184th Brigade had been in the front line since the morning under German artillery - fire . On the right , the sally - ports were under fire and only a few troops reached the German wire ( which was found to be uncut ) before falling back . The left battalion ' s attack towards the Sugarloaf salient ( which was beyond trench - mortar range ) was stopped by German fire at the sally - ports and so the infantry tried to exit along " Rhondda Sap " , under a shrapnel bombardment . Most of the battalion was destroyed , but some troops reached the north - east part of the salient and tried to enter the German breastwork , until all became casualties . On the 5th Australian Division front , the troops attacked over the parapet and had fewer losses than the 61st Division . The 15th ( Victoria ) Brigade advanced next to the British 183rd Brigade , towards the junction of the German line and Layes brook , which ran diagonally across no man ' s land . The right battalion advance was stopped after by machine - gun fire from the Sugarloaf and the left hand battalion was stopped at the German wire , both battalions suffering many losses as the survivors dug in . In the Australian centre the 14th ( NSW ) Brigade had fewer casualties , reached the German front line and took a number of prisoners . When the Australians advanced further they found only flat fields and ditches full of water . A line was selected for consolidation and ten machine - guns were sent forward . The 8th Brigade battalions attacked through machine - gun fire from the front and flanks . A mine was blown on the outer flank with the intention of creating a crater lip that would screen the attacking infantry but when the Australians reached the German breastwork they pressed on , finding the same terrain as the 14th Brigade . The 32nd Battalion , on the eastern flank , suffered heavy casualties while attacking a German stronghold in the ruins of Delangre Farm . Elements of the 14th Brigade reached a main road south of the German line , before withdrawing to the ditch . The Australian 8th and 14th Brigades had gained their objectives and captured about of the German front line . A line was selected for consolidation and a strong - point built at the end of , a German communication trench . Reinforcements with equipment and tools went forward and digging began on a communication trench across no man ' s land , as a German artillery barrage fell and all movement was fired on by machine - guns . By accurate reports reached the 61st Division commander Major - General C . J . Mackenzie of the success on the right and erroneous reports of limited success in the centre and a small lodgement on the Sugarloaf . Mackenzie was ordered by Haking at to attack again at the Sugarloaf to assist the Australians , before it was discovered that the 184th Brigade had not reached it . The Australian 15th Brigade was asked to co - operate with the British attack and the 58th Battalion was sent forward . A renewed bombardment continued , as preparations were made to attack all along the front at , when at Haking cancelled the attack and ordered that all troops were to be withdrawn after dark . Reinforcements for the 182nd Brigade received the order in time but the troops in the German line were overwhelmed , with only a few wounded and stragglers returning . Troops pinned down in no man ' s land withdrew under cover of the bombardment and parties went out to rescue wounded . More discussion between Mackenzie and Haking , led to a decision that the 184th Brigade would attack the Sugarloaf overnight , after a ten - minute hurricane bombardment but German shelling on the British front line then caused a postponement until the morning . The postponement failed to reach the Australian 58th Battalion , which attacked with some of the 59th Battalion and was stopped in no man ' s land with many casualties , survivors from three battalions finding their way back after dark . Despite reinforcements , the situation of the 14th Brigade troops in the German lines became desperate , as artillery fire and German counter - attacks from the open right flank forced a slow withdrawal in the dark . On the left flank , more troops were sent forward with ammunition to the 8th Brigade at dusk and at every soldier who could be found was sent forward . Consolidation in the German lines was slow as the troops lacked experience , many officers were casualties and there was no dry soil to fill sandbags , mud being substituted . German counter - attacks on the front and flanks , with machine - gun fire from Delangre Farm , De Mouquet Farm and " The Tadpole " , began at on 20 July , forcing a retirement to the German first line and then a withdrawal to the original front line . During the withdrawals some troops managed to fight their way out but many were cut off and captured . News of the 8th Brigade retirement reached McKay , the Australian divisional commander , at a meeting with Mackenzie , Haking and Monro to plan the new 61st Division attack . Monro ordered the 14th Brigade to be withdrawn and at a box - barrage around the 14th Brigade began . At the order to retire arrived , although it was not received by some parties . German troops had got well behind the right flank and fired at every sign of movement , forcing the Australians to withdraw along the communication trench dug overnight . By the remnants of the 53rd , 54th and 55th Battalions had returned ; many wounded were rescued but only four of the machine - guns were recovered . Artillery - fire from both sides diminished and work began on either side of no man ' s land to repair defences ; a short truce was arranged by the Germans and Australians to recover their wounded . Air operations . From 14 July the road from Illies to Beaucamps , behind the German front line was kept under air observation . On 16 July 16 Squadron joined 10 Squadron , Royal Flying Corps ( RFC ) on the attack front along with a kite balloon section , bringing the I Brigade squadrons of the RFC in support of the attack up to three corps squadrons and two army squadrons . The corps aircraft photographed and reconnoitred the area before the attack and flew artillery - observation and contact patrols during the battle . Army squadrons flew further afield and denied German reconnaissance aircraft view of British troop movements , particularly behind the XI Corps front . On 19 July , aircraft from two squadrons patrolled the area towards Lille and had numerous air fights , in which two Fokkers and a British DH . 2 were shot down . Bombing raids on German army billets , supply dumps and the railways from Lille to Lens , Douai , Cambrai and Valenciennes also took place . German 6th Army . Opposite the British right , Bavarian Reserve Regiment 17 lost a switch trench facing Trivelet and then a second line was overrun , with the garrison being lost . The left of III Battalion to the south of the Trivelet road , began bombing to its right and part of I Battalion attacked frontally and from the right , taking . On the Australian flank , III Battalion , Bavarian Reserve Regiment 21 was pushed back in the centre and on its right , forming a defensive flank at and in front of Delangre Farm . The right flank of III Battalion , Bavarian Reserve Regiment 16 repulsed the 15th Australian Brigade and was then reinforced by the II Battalion from Rue Delaval , which joined with the left of III Battalion , Bavarian Reserve Regiment 21 . A counter - attack ordered by the divisional commander at , fell into confusion in the dark , under British artillery - fire and an attack on the 8th Australian Brigade , by part of I Battalion , Bavarian Reserve Regiment 21 was stopped by Australian small - arms fire . Later on , two other companies attacked up as I Battalion , Bavarian Reserve Regiment 21 and half of Bavarian Reserve Regiment 20 attacked from the flank , reaching the old front line at on 20 July . The right flank of the 14th Australian Brigade was counter - attacked by most of I Battalion , Bavarian Reserve Regiment 16 , which joined the II Battalion , and recaptured the front line step - by - step , until dawn when a pause was ordered due to exhaustion and lack of ammunition and grenades . When the attack resumed the troops met those of Bavarian Reserve Regiment 21 at around German artillery support was less extensive than that available to the attackers but managed to " smother the British trenches with fire " as the artillery of the 50th Reserve Division and 54th Reserve Division fired from the flanks " thus the backbone of the British ( sic ) attack was broken before it left the trenches at " . Aftermath . Analysis . Neither division was well - prepared for the attack . The 61st Division had disembarked in France in late May 1916 , after delays in training caused by equipment shortages and the supplying of drafts to the 48th Division . The division entered the front line for the first time on 13 June and every man not part of the attack , spent removing poison gas cylinders from the front line , after the discharge on 15 July was suspended when the wind fell ; were removed before the work was stopped , due to the exhaustion of the men . The 5th Australian Division had arrived in France only days before the attack and relieved the 4th Australian Division , on the right flank of the Second Army by 12 July . The Australian divisional artillery and some of the heavy artillery had no experience of Western Front operations and a considerable shuffling of divisions had already taken place , as I Anzac Corps prepared to move south to the Somme front , which hampered preparations for the attack . The attack failed as a diversion , when its limited nature quickly became obvious to the German commanders . A German assessment ( 16 December 1916 ) called the attack " operationally and tactically senseless " and prisoner interrogations revealed that the Australian troops were physically imposing but had " virtually no military discipline " and " no interest in soldiering as it was understood in Europe " . A German report ( 30 July 1916 ) recorded that captured officers said that the Australians made a fundamental mistake , in trying to hold the German second trench , rather than falling back to the front trench and consolidating . When the 15th Australian Brigade was pinned down in no man ' s land , the continuity of the attack broke down and lost protection against flanking fire from the right , which enabled German troops to counter - attack , regain the first trench and cut off the Australian troops further forward . A communiqué , released to the press by British GHQ , was not favourably received by the Australians . It read : " Yesterday evening , south of Armentières , we carried out some important raids on a front of two miles in which Australian troops took part . About prisoners were captured " . Australian losses and doubts about the judgement of higher commanders , damaged relations between the AIF and the British , with further doubts about the reliability of British troops spreading in Australian units , although Grey ( 2008 ) argued that McCay also made errors in judgement that contributed to the result , citing McCay ' s order not to consolidate the initial gains and that poor planning , ineffective artillery support and Australian lack of experience of Western Front conditions , contributed to the failure . A number of senior Australian officers were removed after the débâcle and the 5th Australian Division remained incapable of offensive action until late summer , when it began trench - raiding . In October the 6th Bavarian Reserve Division , with morale high after the defensive success at Fromelles , was sent to the Somme front and never recovered from the ordeal ; Bavarian Reserve Regiment 16 spent ten days in the line and lost . Casualties . The battle was responsible for one of the greatest losses of Australian lives in , although surpassed by the Battle of Bullecourt in 1917 . This was first revealed in detail by Corfield who listed all the names of the dead from the battle . The 5th Australian Division lost , two battalion s were destroyed in the battle and had to be rebuilt : of from the 60th Battalion , one officer and ranks survived and the 32nd Battalion sustained . The 61st Division was already understrength before the battle , engaged half as many men as the 5th Australian Division and lost . German casualties in the 6th Bavarian Reserve Division were . Allied soldiers killed in the area re - taken by the Germans , were buried shortly after the battle . The burial pits were photographed from a British reconnaissance aircraft on 21 July 1916 and marked as dugouts or trench - mortar positions . The bodies were taken by narrow gauge trench railway on 22 July 1916 and buried in eight pits long , wide and deep . Commemoration . New cemetery . Most war graves on the Western Front had been discovered by official surveys during the 1920s and British and Empire dead were reburied in Imperial War Graves Commission cemeteries . Australian soldiers killed in the Battle of Fromelles , were re - buried at the V . C . Corner Australian Cemetery and Memorial , north - west of Fromelles ( the only large exclusively Australian cemetery in France ) . Mortal remains of those killed in no man ' s land were recovered after the war and buried at V . C . Corner British Cemetery . In the late 1990s the site of an unmarked mass grave near Fromelles , was found by Lambis Englezos and other researchers at , near Fromelles at " le bois au fond du village " , known as ( Pheasant Copse / Pheasant Wood ) by the Germans . The researchers believed that the pits had not been found after the war and gained support for an exploration of the site from the Australian Army and the British " All Party Parliamentary War Graves and Battlefield Heritage Group " . In 2007 geophysical survey was commissioned by the Australian government , which indicated that the pits had been undisturbed since the war and contained the remains of approximately . From 23 May – 13 June 2008 an exploratory dig found human remains , personal effects , webbing , brass fitments , uniform badges , buttons and British . 303 ammunition in five of six pits excavated , which were then refilled . Exhumations took place from May – September 2009 , which recovered the mortal remains of soldiers , approximately whom were Australian , from which DNA samples were taken . The original burial site was unsuitable and a new CWGC war cemetery , was built approximately away . On 30 January 2010 , the first body was interred at Fromelles ( Pheasant Wood ) Military Cemetery and the remaining bodies were buried in individual ceremonies by the Royal Regiment of Fusiliers and the Australian Army . In March 2010 , it was reported that soldiers killed at Fromelles , had been identified from DNA . On the 94th anniversary of the battle ( 19 July 2010 ) , the last soldier ( who remained unknown ) was buried . The cemetery was dedicated in a broadcast public ceremony . Memorials and museum . There are several memorials in the Fromelles area commemorating the battle . The V . C . Corner Australian Cemetery and Memorial was built in the early 1920s , the Australian Memorial Park opened in 1998 and the Fromelles ( Pheasant Wood ) Military Cemetery was completed in 2010 . There are other small cemeteries in the area with burials from the battle . In Fromelles Town Hall , there is a museum ( " Fromelles Weppes Terre de Mémoire " ) , run by the " Association pour le Souvenir de la Bataille de Fromelles " ( ASBF ) . A new museum called ' Musee de la Bataille de Fromelles ' is under construction . The plaque in it pays tribute to the pioneering work of Robin Corfield and Lambis Englezos in gaining wider attention to the battle and the loss of life of so many Australians , as well as British soldiers . The museum was originally scheduled to be opened on 19 July 2013 to coincide with the unveiling of some new headstones in the cemetery to mark other soldiers whose remains have been identified .
