On this day in military history…
The Battle of Aubers Ridge took place on 9 May 1915 during the early, grinding phase of the First World War, when both sides were locked into trench warfare along the Western Front. It formed part of a larger Allied effort, coordinated with the French offensive in Artois, to break through German lines in northern France and restore mobility to a war that had become static and costly.
The British First Army, commanded by Douglas Haig, was tasked with the attack. Their objective was to capture the German-held Aubers Ridge, a slight but tactically significant rise in the flat landscape near the village of Aubers. Although not high by most standards, the ridge provided excellent observation over British positions, making it a valuable defensive asset for the German army. Capturing it would not only deny the enemy this advantage but potentially open the way for a breakthrough toward the town of Lille.
The attack began in the early morning hours of 9 May after a short artillery bombardment. This preliminary shelling was intended to cut German barbed wire and destroy frontline defenses, allowing infantry to advance across no man’s land with minimal resistance. However, the British artillery suffered from a severe shortage of high-explosive shells, relying too heavily on shrapnel, which was largely ineffective against entrenched positions and wire obstacles. As a result, much of the German defensive network remained intact.
When British infantry went forward, they encountered devastating machine-gun fire from well-prepared German positions. The German army, anticipating an attack, had constructed deep trenches, reinforced strongpoints, and overlapping fields of fire. Units advancing across open ground were cut down in large numbers before they could even reach the enemy lines. In some sectors, troops became entangled in uncut barbed wire, making them easy targets.
Despite acts of considerable bravery, the attack failed rapidly. In certain areas, small groups of soldiers briefly reached German trenches, but these gains were isolated and quickly reversed. Communication breakdowns added to the confusion, and reserves were committed without clear knowledge of the situation at the front. By the end of the day, it was clear that the assault had achieved no meaningful progress.
The human cost was staggering. British forces suffered over 11,000 casualties in a single day, including killed, wounded, and missing. German losses were far lighter, estimated at only around 1,000. The imbalance highlighted the deadly effectiveness of modern defensive warfare, where machine guns, artillery, and fortified trenches gave a significant advantage to those holding the line.
The failure at Aubers Ridge had consequences beyond the battlefield. It exposed serious weaknesses in British military planning, particularly in artillery preparation and ammunition supply. Public and political reaction in Britain was intense, contributing to what became known as the “Shell Crisis” of 1915. Newspapers reported the shortage of effective shells, leading to criticism of the government and eventually the creation of the Ministry of Munitions under David Lloyd George to address production issues.
The battle also influenced future British tactics. Commanders began to recognise that short bombardments were insufficient against entrenched defenses and that more careful coordination between artillery and infantry was essential. These lessons, learned at a high cost, would shape later offensives such as the Somme in 1916, though even then success remained elusive.
