The German Imperial War Council of 8 December 1912 was an informal conference of some of the highest military leaders of the German Empire. Meeting at the Stadtschloss in Berlin, they discussed and debated the tense military and diplomatic situation in Europe at the time. As a result of the Russian Great Military Program announced in November, Austria-Hungary's concerns about Serbian successes in the First Balkan War, and certain British communications, the possibility of war was a prime topic of the meeting.
In the continuing debate on the causes of World War I, historians like Fritz Fischer, John C. G. Röhl and Pierre Renouvin consider the conference a decisive step to war, long before the July Crisis.
Background
In the First Balkan War of 1912, the Balkan League formed by Serbia, Bulgaria, Montenegro and Greece under Russian patronage quickly defeated the forces of the Ottoman Empire. In Austria-Hungary especially, the Serbian strengthening was seen with increasing discontent, and the German chancellor Theobald von Bethmann Hollweg urged Emperor Wilhelm II to declare his solidarity according to the Triple Alliance—which Wilhelm did, however overstating the case when on 22 November 1912 he openly proclaimed 'the German support under any circumstances'.
Trying to appease the growing sense of alienation, Bethmann Hollweg had his Foreign Office state secretary Alfred von Kiderlen-Waechter publish a newspaper article in the Norddeutsche Allgemeine Zeitung advising Austria-Hungary against a military action, which in turn caused annoyance in Vienna. The chancellor ultimately provoked a diplomatic crisis, when in a Reichstag speech on 2 December he publicly confirmed the alliance with Austria-Hungary. Lord Chancellor Richard Haldane affirmed the concerns of the British government to the German ambassador Prince Karl Max von Lichnowsky and declared that the British would not remain passive in the case of an Austro–Hungarian attack on Serbia, nor would they tolerate any aggression of Germany against France on that occasion.
Kaiser Wilhelm II read Lichnowsky's report of his meeting with Haldane on the morning of Sunday, 8th Dec. The report left Wilhelm furious, lamenting that in the 'Germanic struggle for existence' the British, blinded by envy and inferiority feelings, join the Slavs (Russia) and their Romanic accessories (France). He immediately summoned the 'war council' for 11 AM that same day.
Attendees
Attendees included Kaiser Wilhelm II, Admiral Alfred von Tirpitz (the Naval State Secretary), Admiral Georg Alexander von Müller (the Chief of the German Imperial Naval Cabinet), General von Moltke (the Army's Chief of Staff), and Admiral August von Heeringen (the Chief of the Naval General Staff). One source also claims that the Chief of the German Imperial Military Cabinet General Moriz von Lyncker attended, and also General Josias von Heeringen, the Prussian Minister of War (and brother of Admiral von Heeringen), but no other of the four primary sources supports their attendance, and one primary source specifically states the War Minister was not invited. All sources agree that Chancellor Bethmann Hollweg was not there. The importance of this meeting can be seen in that the leaders of both the German Army and Navy attended.
Discussions
Wilhelm II called British balance of power principles "idiocy," but agreed that their statement was a “desirable clarification” of British policy. His opinion was that Austria-Hungary should attack Serbia that December, and if “Russia supports the Serbs, which she evidently does…then war would be unavoidable for us, too,” and that this would be better now than later, after completion of (the just begun) massive modernization and expansion of the Russian army and railway system toward Germany. Moltke agreed. In his professional military opinion "a war is unavoidable and the sooner the better". Moltke "wanted to launch an immediate attack."
