The Attack at Fromelles (French pronunciation: [fʁɔmɛl] (Battle of Fromelles, Battle of Fleurbaix or Schlacht von Fromelles) was a military operation on the Western Front during the First World War on 19–20 July 1916. The attack was carried out by British and Australian troops and was subsidiary to the Battle of the Somme. General Headquarters (GHQ) of the British Expeditionary Force (BEF) had ordered the First Army (General Charles Munro) and Second Army (General Herbert Plumer) to prepare attacks to support the Fourth Army on the Somme, 50 mi (80 km) to the south, to exploit any weakening of the German defences opposite. The attack took place 9.9 mi (16 km) 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 by both sides consisted of building breastworks, rather than trenches.
The operation was conducted by XI Corps (Lieutenant-General Richard Haking) of the First Army with the 61st (2nd South Midland) Division and the 5th Australian Division of the Australian Imperial Force (AIF) against the 6th Bavarian Reserve Division, supported by the 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 outnumbered 2:1. The advance took place in daylight, on a narrow front, against defences overlooked by Aubers Ridge, with German artillery on either side free to fire into the flanks of the attack. Another attack by the 61st (2nd South Midland) 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 Erich von Falkenhayn, head of Oberste Heeresleitung (OHL, the German army supreme headquarters) judged Fromelles to be the offensive he expected against the 6th Army. The attack gained no ground but inflicted some casualties; next day the failure was evident and a captured operation order from XI Corps revealed the limited nature of the operation. In 2012, a study of German records showed that none of the German divisions opposite XI Corps moved to the Somme until four to nine weeks later; Falkenhayn sent divisions from the Souchez–Vimy area, 20 mi (32 km) south instead, which has been misinterpreted in earlier accounts. The attack was the début of the AIF on the Western Front and the Australian War Memorial described it as "the worst 24 hours in Australia's entire history". Of 7,080 BEF casualties, 5,533 were suffered by the 5th Australian Division; the Germans suffered 1,600–2,000 casualties and lost 150 prisoners.
Background
On 5 July, during the Battle of the Somme (1 July – 18 November 1916) GHQ informed the three other British army commanders that the German defences on the Somme 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. Gaps were to be widened to exploit weakness and disorganisation of the German defence. The Second Army commander, General Herbert Plumer, was occupied by preparations for an offensive at Messines Ridge but could spare a division for a joint attack with the First Army at the army boundary. On 8 July, General Charles Monro (First Army) ordered the XI Corps commander, Lieutenant General Richard Haking, to plan a two-division attack; Haking proposed to capture Aubers Ridge, Aubers and Fromelles but the next day Monro dropped Aubers Ridge from the attack, as he and Plumer thought that no great objective could be achieved with the troops available.
On 13 July, after receiving intelligence reports that the Germans had transferred about nine infantry battalions from the Lille area from 9 to 12 July, GHQ informed the two army commanders that a joint attack was to be carried out around 18 July, to exploit the depletion of the German defenders. Haking was ordered to begin a big preliminary bombardment to simulate a large offensive and conduct a local infantry attack on 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 Germans had not collapsed after the British success at the Battle of Bazentin Ridge (14 July 1916). Sir Douglas Haig, Commander-in-Chief of the BEF, did not want the attack unless it could succeed and Monro and Haking opposed a postponement or cancellation. The weather had been dull on 15 July and next day, soon after Monro and Haking made the decision to go ahead, it began to rain. Zero hour for the main bombardment was postponed because of the weather and at 8:30 a.m., Haking delayed the attack for at least 24 hours; after having second thoughts, Monro postponed the operation until 19 July.
Prelude
Offensive preparations
The Second Army provided the 5th Australian Division (Major General James McCay), the artillery of the 4th Australian Division and heavy guns and trench mortars to XI Corps, for an attack from the Fauquissart–Trivelet road to La Boutillerie, with the 31st Division and 61st (2nd South Midland) Division. Lack of artillery, training and experience in the Australian divisional artilleries and some of the heavy batteries, led to the attack front being reduced to 4,000 yd (2.3 mi; 3.7 km) between the Fauquissart–Trivelet road and Delangre Farm. The ground was waterlogged, flat and visible from Aubers Ridge behind the German front to the south.
The 39th Division and 31st Division moved their boundaries north as the 61st (2nd South Midland) Division concentrated along the Fauquissart–Trivelet road to Bond Street. The 20th (Light) Division moved its boundary south to Cordonnerie Farm on the left of the 5th Australian Division, which concentrated from Bond Street to Cordonnerie Farm. The twelve attacking battalions were supported by more artillery than the Battle of Aubers Ridge in May 1915, more ammunition was available and there were trench mortars for wire cutting. With support from First Army artillery to the south, 296 field guns and 78 heavy 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 rain, visibility was better on 18 July and the artillery bombardment proceeded. The shelling of the German front at La Bassée was repeated and the German artillery retaliated.
Plan
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 5th Australian Division was to attack the left flank of the salient by advancing south as the 61st (2nd South Midland) Division attacked on the right flank from the west. Each division was to attack with 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 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 100–400 yd (91–366 m) wide, before the British artillery fire was lifted from the front line; the infantry would rush the surviving Germans while they were disorganised and advance 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 (more rain 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, then the artillery was to resume bombardment of the front line to catch the German infantry out of cover.
German preparations
General Erich von Falkenhayn, the German Chief of the General Staff, 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. An elaborate, carefully sited and fortified front position was built behind fields of barbed wire, with camouflaged concrete machine-gun nests and a second trench (Wohngraben) close behind the front trench (Kampfgraben), to shelter the trench garrison during bombardments. Communication trenches were built to evade Allied artillery-fire intended to obstruct the movement of reinforcements from the new rear defences.
The front position was to be held at all costs as the main line of resistance but in May 1915, Falkenhayn ordered a reserve position to be built along the Western Front, 2,000–3,000 yd (1.1–1.7 mi; 1.8–2.7 km) behind the front position, out of range of enemy field artillery. To contain a breakthrough, the second position was to be occupied opposite a sector broken into and serve as a jumping-off point for counter-attacks. If the front line could not be recovered, the rear position could be connected to the remaining parts of the front line on either side to contain the break-in.
The construction programme was a huge undertaking and was completed in late 1915. The fortification programme had several opponents, notably the 6th Army commander Crown Prince Rupprecht, who claimed that a rear position 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) and in July 1916, the 6th Bavarian Reserve Division held a 4.5 mi (7.2 km) stretch of the front 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 75 shelters with 9–12 in (230–300 mm) of concrete protection. After a British gas attack opposite Neuve Chapelle and Fauquissart late on 15 July, German artillery bombarded the British front line and a raid on the Australian lines by 100 troops of Bavarian Reserve Infantry Regiment 21, caused nearly 100 casualties, taking three prisoners, for a loss of 32 casualties.
Attack
First Army
Patrols during the night reported no movement 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 on the left. It was hazy early on 19 July but the artillery zero hour was fixed for 11:00 a.m., ready for the attack at 6:00 p.m. A special heavy artillery bombardment began on the Sugarloaf at 2:35 p.m., by which time a German counter-bombardment was falling all along the attack front, causing casualties to the Australians and the field gunners of the 61st (2nd South Midland) 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 5:30 p.m.
In the 61st (2nd South Midland) Division area, infantry of the 182nd Brigade on the right flank, began to move into no man's land through sally ports but some were under German machine-gun fire and became death traps. Two companies of the right-hand battalion managed to get within 50 yd (46 m) of the German parapet, with few casualties, then 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 German flanking fire caused many casualties and German artillery began to bombard the captured area. The left-hand battalion lost more men in no man's land and then found that the wire at the Wick salient was uncut. The few infantry to get through the wire were shot down short of the front trench; reinforcements were also caught in no man's land and pinned down.
In the centre, the 183rd Brigade was bombarded before the advance began and shrapnel shell-fire prevented the infantry from using the sally ports. After climbing the parapet, both battalions were shot down in no man's land, only a few men got 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 under German artillery-fire all morning. On the right, the sally ports were under fire and only a few troops reached the German wire, finding that it was uncut, before falling back. The attack of the left-hand battalion towards the Sugarloaf salient (which was beyond trench-mortar range) was stopped by German fire on the sally ports; the British tried to exit along "Rhondda Sap", which was under 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; all became casualties.
On the 5th Australian Division's front, the troops attacked over the parapet, suffering fewer casualties than the 61st (2nd South Midland) 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 by machine-gun fire from the Sugarloaf after 300 yd (270 m) and the left hand battalion ran into uncut wire, both battalions suffered many casualties 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 pressed on, 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 Australian Brigade battalions attacked through machine gun fire from the front and flanks. A 1,200 lb (540 kg) mine was blown on the outer flank to make a crater lip to screen the attacking infantry but when the Australians reached the German breastwork they kept going, finding the same terrain as the 14th Australian Brigade.
