Germany's Military Collapse in 1918

From The Weimar Years: Rise and Fall 1918–1933, by Frank McDonough (Bloomsbury, 2023), Kindle pp. 26-28:

Victory in Russia gave the German people real hope of victory in the war. On 21 March 1918, Germany launched a spring offensive, better known as the Ludendorff Offensive, on the Western Front. It aimed to knock Britain and France out of the war before significant numbers of US forces arrived in Europe. Unfortunately, German expectations of victory proved illusory. Scarcely in the annals of military history has there been such a spectacular reversal of military fortune as Germany suffered towards the end of the war. By early June 1918, it was clear that the Ludendorff Offensive had failed. On 8 August, the British Expeditionary Force (BEF), spearheaded by tanks and supported by massive numbers of newly arrived American troops, launched a surprise attack between Amiens and St Quentin in northern France against the German Second Army. It punched a huge hole in the defensive line and captured 15,000 German soldiers. The significance of this decisive British breakthrough in the Battle of Amiens was not lost on Ludendorff, who called it ‘the blackest day of the German army in the history of this war’. He knew the Allies were now able to deploy thousands of tanks on the Western Front while the Germans had been able to manufacture only 20. Fritz Nagel, a German officer in the German anti-aircraft artillery, later recalled: ‘The German armies were in bad shape. Every soldier and civilian was hungry. Losses in material could not be replaced and the soldiers arriving as replacements were too young, poorly trained and often unwilling to risk their necks because the war looked like a lost cause.’

A two-day military conference on the critical situation on the Western Front was held on 13–14 August 1918 at the headquarters of the Supreme Military Command in Spa, Belgium. Hindenburg chaired it, and Paul von Hintze, the new Foreign Minister, and Ludendorff were present. Ludendorff said Germany now needed to adopt a purely defensive strategy, but he thought it might still be possible to sue for peace with the western Allies on favourable terms. Hindenburg agreed with Ludendorff’s judgement about continuing with strategic defence, while Hintze thought the German Army was in no condition to fight a successful strategic defence, and he felt diplomatic steps had to be taken to bring the war to an end.

When Kaiser Wilhelm II was apprised of these discussions in a Grand Council meeting, he seemed blinded by the optimism of Hindenburg and Ludendorff, and instructed Hintze to refrain from making a direct peace offer to the Allies and to wait for a more favourable moment. This proved wishful thinking, as Germany’s Central Power allies now began to collapse. On 24 September 1918, the Bulgarian Army was defeated when the Allied armies based in Greece broke through the Macedonian Front. The Bulgarian government, which had previously been under German control, requested an armistice and accepted it five days later. This placed the Austro-Hungarian empire, Germany’s principal ally, in a precarious position. Emperor Charles I of Austria, desperate to end the war, sent a circular diplomatic note inviting all the belligerents in the war to send representatives to Vienna to a confidential conference to discuss the basic principles of a peace settlement. On 27 October, Austria-Hungary ended its formal alliance with Germany, and the subject nationalities of the Habsburg Empire all declared their independence. On 30 October, the Ottoman Turks signed a regional armistice. Germany was now left without any allies.
