German troops pass through a French village as part of Germany’s strategic retreat on the Western Front in 1917. The withdrawal, meant to shorten German lines to allow for the accumulation of much-needed reserves, threw complicated Allied plans for attack in 1917 into disarray.
INTRODUCTION
Pause for Breath
After three years of brutal warfare on the Western Front, and after the twin bloodlettings of Verdun and the Somme, the combatant nations paused to take stock of the strategic situation at the beginning of 1917. Fearing a repetition of the horrible attritional battles, each of the belligerent powers would gamble everything on victory in 1917 but would fall short.
The carnage of Verdun and the Somme had a pervasive effect on World War I as a whole and on the Western Front in particular. The twin battles shattered lives, ended some military careers and advanced others, toppled governments and altered strategic planning. At the most personal level, Verdun and the Somme had fundamentally altered the lives of their soldier participants. Far from the quick and glorious victories that many had expected in 1914, the titanic battles for many had instead epitomized slow, senseless slaughter and the sacrifice of a generation. German lieutenant Ernst Jünger spoke for many:
Field Marshal Paul von Hindenburg (centre), who had risen to fame first at the Battle of Tannenberg, and then as the overall commander of the Eastern Front, in 1916 took control of Germany’s overall military policy, working in tandem with General Erich Ludendorff.
‘For I cannot too often repeat, a battle was no longer an episode that spent itself in blood and fire; it was a condition of things that dug itself in remorselessly week after week and even month after month. What was a man’s life in this wilderness whose vapour was laden with the stench of thousands upon thousands of decaying bodies? Death lay in ambush for each one in every shell-hole, merciless, and making one merciless in return. ... There it was [at the Somme]that the dust first drank the blood of our trained and disciplined youth. Those fine qualities which had raised the German race to greatness leapt once more in dazzling flame and then slowly went out in a sea of mud and blood.’
At the strategic level, Junger’s commander, General Erich Ludendorff, who along with Field Marshal Paul von Hindenburg had effectively taken control of the German war effort, had to come to terms with the legacy of 1916. Admitting in his memoirs that the battles of Verdun and the Somme had left Germany ‘completely exhausted on the Western Front’, Ludendorff summarized the strategic implications of the resulting situation:
‘The Supreme Army Command had to bear in mind that the enemy’s great superiority in men and material would be even more painfully felt in 1917 than in 1916. It was plainly to be feared that early in the year “Somme fighting” would burst out at various points on our fronts, and that even our troops would not be able to withstand such attacks indefinitely, especially if the enemy gave us no time for rest and for the accumulation of material. Our position was unusually difficult, and no way of escape was visible. ... The future looked dark.’
Although Field Marshal Sir Douglas Haig, in command of the British Expeditionary Force, and General Joseph Joffre, who led the French forces on the Western Front, were fully conscious of the fearsome butcher’s bill that their nations had paid during the fighting of 1916, they interpreted Verdun and the Somme as costly victories. Working within that military analytical framework, on 16 November 1916, Haig and Joffre met at the Chantilly Conference to begin work on the strategic plan for the coming year and were primarily concerned with maintaining an unrelenting pressure on the Germans in both France and Flanders. Joffre explained his plan for 1917 rather bluntly: ‘I have decided to seek the rupture of the enemy’s forces by a general offensive executed between the Somme and the Oise at the same time as the British Armies carry out a similar operation between Bapaume and Vimy.’
It also became clear at Chantilly that, due to the price of Verdun, Britain would have to shoulder an ever-increasing military load on the Western Front. The changed Allied strategic balance, coupled with instructions from Prime Minister Herbert Asquith regarding the pivotal value of the German submarine bases on the Belgian coast, prompted Haig to press Joffre to agree that a British offensive in Flanders form the first part
